White Paper, Miner, Pizza … |

Museum has played the role of a time recorder. Talking about bitcoin, more than ten years has passed since the creation of it. Although it is uncomparable to the stock market with a hundred years of history, during the ten years, in the different stages of the development of bitcoin and blockchain have continuously poured in geeks, miners, speculators, newbies, leaving keywords such as sudden rich, myth, scam, belief, revolution, etc.
There are also many “old objects” with stories in the “Museum” of the cryptocurrency realm. On Museum Day, let ’s review the stories brought by these “old objects”.
The First Digital Currency White Paper — Bitcoin White Paper
On Oct. 31, 2008, Satoshi Nakamoto released the Bitcoin white paper — A Peer-to-Peer Electronic Cash System in the cryptographic mail group where he belongs, and Bitcoin was born since then.
A white paper is a document that explains the purpose and technology used in cryptocurrency. Usually a cryptocurrency uses the white paper to help people understand what it provides, and it is also an important information channel for investors to understand a project. Therefore, the level of the white paper affects people’s confidence towards the coin.
In a word, in the cryptocurrency and blockchain industry, the value of a white paper is equivalent to that of a standard financing speech. The white paper plays a vital role in this emerging market.
The First Public Bitcoin-Physical Transaction — Pizza
Since Satoshi Nakamoto mined the Bitcoin genesis block on January 3, 2009, Bitcoin has only been spread among the small crowd and has not realized its value.
Not until May 22, 2010, Bitcoin enthusiast “Laszlo Hanyecz” bought a pizza coupon worth $25 with 10,000 bitcoins. This is the first public bitcoin-physical transaction. Bitcoin has its price with 0.3 cents per bitcoin.


This day has also become the famous “Bitcoin Pizza Day” in Bitcoin history. Bitcoin as the imagination of the financial system has more practical significance. The tenth anniversary is coming. How will you commemorate it? Will you buy a pizza?
The First Digital Asset Exchange — Bitcoinmarket.com
After the birth of Bitcoin, in addition to mining, the only way to get Bitcoin in the early days was to conduct transactions on forums or IRC (commonly known as Internet Relay Chat). However, this method involves both long transaction time and great security risk.
In March 2010, the first digital asset exchange — Bitcoinmarket.com launched. However, due to lack of liquidity and transaction depth, it disappeared soon after its establishment, but Bitcoinmarket.com opened the era of the operation of the cryptocurrency realm exchange 1.0.


On June 9, 2011, China’s first Bitcoin exchange — Bitcoin China (BTCChina) launched. Its founder, Yang Linke, translated Bitcoin into Chinese “比特币” for the first time. In 2013, China’s bitcoin trading entered the golden age, and exchanges sprung up. China monopolized more than 90% of the world’s bitcoin transactions. Now, if the top three exchanges Binance, Huobi Global, OKEx are the Exchange 2.0, then the index exchange represented by 58COIN called the 3.0 version, leading the trend.
The First Generation of High-Performance Miner — ASIC Miner
When Satoshi Nakamoto created Bitcoin, the only way to get it is to use computers (including home computers) to mine, mainly relying on the CPU to calculate. However, as the value of digital currencies such as Bitcoin has become higher and higher, mining has become an industry with the competition is getting fiercer, accompanied by increasing difficulty of mining. Therefore, hardware performance competition starts.
In July 2012, the genius Jiang Xinyu (Internet nickname is “Friedcat”) from the junior class of the University of Science and Technology declared at the forum that he could make ASIC miners (chips). As far as mining computing power is concerned, ASICs can be tens of thousands or more higher than the same-generation CPUs and GPUs.
At the beginning of 2013, Zhang Nanqian (Pumpkin Zhang), a suspended doctoral student from the Beijing University of Aeronautics and Astronautics, developed the ASIC miner and named it “Avalon”.


In June 2013, the Friedcat’s miner USB was finally released, and it maintained 20% of the computing power of the entire network.
At the end of 2013, Wu Jihan, used the tens of millions yuan earned from Friedcat through investment, worked together with Jenke group, to develop the Antminer S1. Since then, the miner manufacturer Bitmain began to enter the stage of history.
It is no exaggeration to say that Friedcat and Zhang Nangeng have opened the domestic “mining” era.
The Birthplace of China’s Bitcoin — Garage Coffee
It is not only the “old objects” that record history, but also a place that everyone in the cryptocurrency realm aspires to.
Guo Hongcai once said, “Without no The Garage Café, there will be no cryptocurrency realm today. Since it is a very mysterious place that all waves of people from the café joint together to create today’s digital asset industry.

▲ In March 2013, American student Jake Smith successfully purchased a cup of coffee at The Garage Café with 0.131 bitcoins. This move attracted the attention of CCTV, and it conducted an interview.
Indeed, The Garage Café is the world ’s first entrepreneurial-themed coffee shop. It has been legendary since its establishment in 2011. The Garage Cafét is not only the core coordinate on China’s Bitcoin map, but also the birthplace of the Chinese cryptocurrency circle, where digital asset realm tycoons including Guo Hongcai, Zhao Dong, Li Xiaolai, Li Lin have made their ways.
The development of digital currency is only 11 years old. Through these “old objects”, we review the various stories of this wave of technology together, hoping to help you understand the development process of the digital currency field. Meanwhile, I also remind all practitioners to use history as a mirror and forge ahead.

  • Atomix HD Tezos Wallet
HD wallets (hierarchical deterministic wallet) are the wallets that use a single 12 or 18-word mnemonic phrase that is used to identify following addresses and private keys in a wallet software. Atomix is HD wallet that supports Tezos, it merges benefits of decentralized and centralized exchanges. With Atomix, all private keys are kept encoded on the computer. No identity verification or registration is required to use the wallet.
  • Simplestaking
Simplestaking is Tezos focused wallet being a web app and desktop app with support for hardware wallet Trezor Model T. The wallet is developed using NgRx state management and Angular framework.
  • Galleon Tezos Wallet (Tezori)
Galleon is a smart open source wallet for XTZ that supports both hardware and software wallets on Windows, Linux and Mac. It was developed by Cryptonomic and funded by the Tezos Foundation.
  • Tezos CLI Wallet
The Tezos CLI wallet can be used by those users who have some coding understanding while it requires the use of command lines. Tezos has mentioned the wallet on its website and has been audited by an independent external security inspector. As the Tezos CLI needs some level of command line knowledge, it can be quite difficult to use.

How to keep your wallet safe

A cryptocurrency wallet can be regarded as a regular wallet with money, but it has advanced features, which increases the level of risk. Simple rules will help prevent the loss of your own savings:
  1. Do not store large amounts for long periods on wallets that do not provide full control. It is better to store large amounts for a long time only in wallets that provide full control over the private key and, accordingly, over digital assets. This will help protect your coins against fraud and cyber attacks.
  2. Encrypt information and back up private keys. In case of reinstalling the PC or the occurrence of force majeure situations, this will help to restore access to the wallet quickly.
  3. Store secret keys on an offline device. It is preferable to use a platform that is not accessible for hacking via the Internet.
  4. Use reliable antivirus software and update it regularly. This will prevent the leakage of personal data that hackers can use to crack passwords.
  5. Register several types of wallets. It will allow you to distribute your funds and use the most suitable wallet depending on the situation.
If you use your Tezos wallet wisely and do not neglect the precautions, the risk of funds loss will be minimized.

5 unique hardware wallets of 2019

5 unique hardware wallets of 2019

https://preview.redd.it/vlyx9v097rq31.jpg?width=1080&format=pjpg&auto=webp&s=ca7a84bb60fd36f51f95a444980fa2d70827f229
Currently, Ledger and Trezor dominate among all hardware wallets, and they have no equal. However, there are others who are also trying to occupy their niche and attract as many users as possible. Let’s consider 5 unique wallets that experts have reviewed.
YubiKey. This is not quite a cryptocurrency wallet. Although it doesn’t store cryptocurrency, it makes it possible to provide an additional step for entering online accounts and is associated with cryptocurrency exchanges. The largest exchanges work is with this wallet. Despite the fact that it has been working for 12 years, only this year it has become more noticeable in the market. After the hacking on the Binance exchange, the site management began to recommend it as a good security module.
SafePal. This hardware wallet belongs to a new generation. It combines security and mobility with accessibility. It is much easier using it than leading wallets. Now the wallet has added a number of altcoins, in adition to Bitcoin. Analysts believe that it has a very good chance of becoming one of the leaders.
Cobo Vault. This wallet doesn’t transfer data via Wi-Fi, USB, NFC networks. All data is erased if there is a violation in the security system. It can be only activated. It also offers another line of defense. All keys are stored on equipment that military structures use for their own purposes.
Ballet. This standalone wallet doesn’t have electronic components. This is a simple metal card. The private key is stored by printing. This wallet is used by many exchanges in China, and now it can go global.
Kastelo. This hardware wallet has open source code. It is developed by the Monero community. It doesn’t have a wireless transmitter. It is open and transparent. The project is independent and is being developed by several people. Now the wallet is trying to break into leading platforms. Each of the wallets has its advantages and disadvantages. Developers are trying to eliminate vulnerabilities by providing users with additional security features.

Coinbase Tutorial. A Definitive Guide for Newcomers.

Coinbase Tutorial. A Definitive Guide for Newcomers.

As cryptocurrencies become more abundant throughout our society, more information must be prevalent to educate the newcomers into the world of cryptocurrency and blockchain technology. If you’re new to cryptocurrencies, then you’ve come to the right place as Coinbase is one of the simplest cryptocurrency trading platforms to get started on. Once you understand Coinbase, more advanced trading platforms such as Binance won’t seem as intimidating.

What is Coinbase?

Coinbase is a cryptocurrency trading platform which allows you to buy and sell five different cryptocurrencies: Bitcoin, Bitcoin Cash, Ethereum, Ethereum Classic, and Litecoin. Note that there are over thousands of different cryptocurrencies but these four are what Coinbase specializes in.

Making a Coinbase account

Creating a Coinbase account is very simple but there’s much more to it compared to something like creating a Reddit account. Be sure to have either your driver’s license, passport, or identification card at hand as you’ll be asked to provide this information via upload.
Coinbase currently has a sign-up promotion going on. If you haven't signed up yet, sign up using this link and you'll receive $10 free in bitcoin (after you spend $100).

Why does Coinbase need to see my ID?

Coinbase needs to be able to verify your identify because they are a regulated financial service company operating in the US. As they state on their website:
As a regulated financial service company operating in the US we are periodically required to identify users on our platform. This ensures we remain in compliance with KYC/AML laws in the jurisdictions in which we operate, something that is necessary for us to be able to continue to offer digital currency exchange services to our customers.
Once you’ve created your account, you’ll have to wait until you get approved before you’re allowed to start buying and trading on the platform. This can take upwards of 7 days till approval. Coinbase will also make two distinct small charges towards your bank account. You will need to find these charges and register them into Coinbase as a part of the approval process.
The time in which it’ll take to get approved will vary person to person, just be patient and you eventually will get approved. In the mean-time I highly recommend taking some extra steps done to ensure the security, and longevity of your account.

Securing Your Coinbase Account

Two Factor Authentication

Upon signing into your Coinbase account, you’ll be sent a text message containing a code in which you will have to input allowing you to access your account. This is a security measure done to ensure it is specifically you trying to access your account, it’s important to note that a hacker could still compromise your account through a social engineering attack with what is known as a phone porting attack. This attack is done after obtaining your phone number and various other personal information, the hacker will then call up your phone carrier impersonating you, and then attempt to port your number over to a new device. Once a hacker has access to your text messages, they can then access your account with your SMS two-factor authentication code. If you’d like to see a real example of how this can play out, Cody Brown shares his example of how he lost $8k worth of bitcoin to this attack.
Anyways, the best way to prevent this is through the use of an authenticator. The most common being Google Authenticator. I don’t want to get into too much technical details as to how authenticators work. Think of it as a digital key, stored on a device that changes every 30 seconds.
In order to enable authenticator for Coinbase, go to Settings > Security and Enable Authenticator as shown here. After that a prompt will appear along with a QR code and a secret code (comprised of a random string of 16 letters & numbers). You will need to open up your Google Authenticator app and scan in your QR code. You will also need to write down your secret code and keep it in a safe place such as a safe and/or security deposit box.
Once enabled, any time you wish to access your Coinbase account or make trades/transfers, you will need access to the 6-digit code provided by your authenticator.
IMPORTANT: If you lose access to the device you’ve enacted authenticator on, you ABSOLUTELY WILL NOT be able to recover your account UNLESS you have that 16 digit secret code. This is a serious matter that should be taken with serious caution. It is important you take preventative security measures to ensure the security of your cryptocurrency. I highly recommend calling your bank and opening a security deposit box. This will mostly likely cost a yearly fee but the peace of mind alone is worth it IMO.

Phishing Schemes

I’d like to briefly touch on phishing schemes. Phishing is the act of attempting to obtain personal information through the use of social engineering. Common phishing schemes/methods include: fraudulent e-mails in which the sender tries to impersonate an entity of authority (we’ve all received these sketchy e-mails before) and websites registered under the misspelling of a popular domain. In the world of crypto, it is essential to be attentive to schemes like these as it is much easier to fall victim than you may think. The anonymity of crypto alone makes it very appealing to hackers & scammers. You should always be on the lookout for fraudulent schemes.
Some preventative actions you may want to consider taking:
  • Creating a bookmarks folder of all the popular crypto-related sites you visit
  • Creating email inbox rules to distinguish trusted entities.
  • As a safety precaution, ensure you have authenticator enabled throughout all your crypto-related accounts with the security keys kept in a safety deposit box.
  • Use a hardware wallet to store your cryptocurrency instead of keeping them on exchanges (I’ll touch more on this later)

Funding Your Coinbase Account

Congratulations, your Coinbase account got approved! You can now start funding your account… or so you thought.
Upon your first cryptocurrency purchase with Coinbase, it is very likely your bank will automatically flag the purchase as fraudulent. If this happens to you (which it most likely will), you will need to call up your bank and let them know to let the purchase go through.
Once you’ve taken care of that, buying and selling cryptocurrency is relatively self-explanatory. Just go to Buy/Sell in the menu and choose which currency you’d like to buy/sell as shown below.

Funding Limits

Coinbase has weekly limits as to how much cryptocurrency you may purchase. Your limits will not start out this high but increase with proper verification and the longer you have an account.
Weekly Buy Limits
  • Cash: $100,000
  • Bank Account: $25,000
  • Credit/Debit Card: $7,500
Weekly Sell Limits
  • $100,000
Credit/Debit Card and bank account purchases are both instantaneous, however, for bank account purchases, it'll take 5-7 business days for you to see the charge in your account.
For information see:

Fees

There’s three distinct fee’s you will encounter with Coinbase.
  • Conversion & Exchange Fees: These are fees you’ll encounter through the buying, selling or exchanging of crypto. A fee is charged when you convert fiat to crypto.
  • Transfer Fees: A fee is charged if you’re transferring crypto to a different wallet (IE: Crypto Binance). Note that if this wallet happens to be another Coinbase wallet, there is no fee.
  • Mining Fees: These's are inherent fee's you'll encounter with any sort of crypto transaction. Mining fee's will also change depending on which cryptocurrency you are purchasing. I don't want to delve to much into the technical aspects as to why this is (as it can get very technical). I'll have to save this for a later post.
Note that the Bitcoin network is notorious for insanely high fee's. Purchase and transaction fee's upwards of $50+ are not uncommon during periods of high network congestion. Using Bitcoin to purchase something like a cup of coffee is completely trivial, and as we advance forward into the space, it's becoming more apparent that Bitcoin's main use case will be that of a digital gold rather than a global payment network.

Lowest Possible Fee With Coinbase

If you're going to be making large crypto purchases through Coinbase, ideally you'd want to get the lowest fee possible. I have found that the best way to do this is by your linking a bank account rather then by purchasing through debit/credit card. See photo.
  • Funding via bank account: 1.46% fee
  • Funding via debit/credit card: 3.83% fee
See photo.
As you can see, both allow instantaneous availability of funds. However, it'll take 5-7 business days for the bank account transfer charge to appear in your account.
Note: The fee you receive will also depend on how large of an amount you are purchasing. Expect fees to be a bit higher for smaller purchasing amounts and lower for larger amounts.

Fees Continued

It's important to know that fees will change depending on what country you're from and what cryptocurrency you happen to be purchasing. For more information on Coinbase fees I highly recommend visiting their fee disclosure page.

Avoiding Coinbase Transfer Fees Using GDAX

There is a bit of loophole to avoid Coinbase transfer fees. This is done through Coinbase’s advanced trading platform known as GDAX. It looks intimidating, but it’s a lot easier to use than they make it seem. Luckily, as Coinbase user, you technically already have a GDAX account. Simply follow the sign-up steps for GDAX, and you’ll find your information pre-populated. No need for long wait-times for verification etc.
To mitigate Coinbase transfer fees, send your money: Coinbase - GDAX - wallet of your choice

Sending & Receiving Cryptocurrency

Sending and receiving crypto with Coinbase is super easy…

Sending

Go to Accounts in the menu, look for the currency you’d like to send, then click Send. A prompt will come up instructing you to put in the recipients address and the amount you’d like to send. Ethereum example.

Receiving

Go to Accounts in the menu, look for the currency you’d like to receive, then click Receive. A QR code and random string of numbers will appear. That random string of letters & numbers is your wallet address. This string is what you’d give to someone if you were looking to receive crypto. Your wallet address is also crypto specific. This means that if you try to send Litecoin to your Bitcoin wallet address, the transaction will fail.
Random LPT: If you’re ever needing to transfer a large amount of crypto to another wallet, I recommend sending a test amount which is basically just a small amount of crypto. If said small amount appears in the wallet, you know you have the correct address. If not… you may need to just wait a bit longer and hopefully it will appear, or you’ve sent it to the wrong wallet address.

Securing Your Cryptocurrency

There are many ways you could go about securing your cryptocurrency. I’m going to discuss two.

The Vault

The Vault is a feature Coinbase offers free of charge to safeguard your funds by adding multiple layers of security. With the vault, there is a designated time frame for withdrawals. This helps to safeguard against hackers getting into and emptying your account. Additionally, you can have other people (or email addresses) needed to confirm these withdrawals for an added layer of security.
Warning: The vault is a feature you should use if you are planning on holding your cryptocurrency for a longer period of time. It is not recommended if you are looking to turn quick profits through buying and selling often due to the 3 day waiting period for withdrawals.

Ledger Nano S

The Ledger Nano S is a cryptocurrency hardware wallet. It allows you to store your cryptocurrency in physical device akin to that of a USB drive. You would then ideally keep this in a safe at home. This is my personal preferred method of storing cryptocurrency because I don’t have to worry about hackers potentially gaining access to my cryptocurrency online, rather, that security falls into my own hand. I just have to make sure I don’t lose or damage my Ledger, and even if I managed to do that, there is a 16 word recovery phrase provided by the Ledger in the event of a lost, damaged, or stolen Ledger. As long as you have the recovery phrase, you can recover all your cryptocurrency.
So after purchasing crypto through Coinbase, instead of leaving my digital goods on the exchange, I transfer it to cold storage (which is another word for hardware wallet IE: Ledger Nano S).

My Primary use of Coinbase

I primarily use Coinbase as an easy access point into the crypto world. Coinbase makes it very easy to purchase the largest of cryptocurrencys and once you have access to these, you can start purchasing more niche cryptocurrencies such as Ripple, EOS, IOTA, NEO, etc... You would do this through the use of much larger exchange such as Binance.
You cannot directly convert fiat to crypto with Binance yet. So in order to fund a Binance account, you need to convert your fiat to crypto through an exchange that allows you to do so, (this is where Coinbase comes into play) send that crypto to your Binance account, then make a purchase.
The way I go about doing this is:
  • 1st I purchase Ethereum through Coinbase. I purchase Ethereum instead of Bitcoin, because as I mentioned before, Bitcoin is notorious for insanely mining and transaction fees. Ethereum has much lower fees.
  • 2nd I send said Ethereum to my Binance account
  • 3rd Once I receive that Ethereum on my Binance account, I make my niche cryptocurrency purchase through the Binance exchange.
I have a step-by-step guide that details out this process. You can view it here.
PHEWWWW. That was a lot of words... Anyways, I hope this was beneficial to you crypto newbies out there. I plan on making more tutorials like this in the future :) If you have any questions, just leave them in the comments sections down below. I’m sure either myself or the community would be able to respond.

My attempt at an ELI5 for cryptocurrency to help my friends.

This is a long one so fair warning and no there is no tl;dr. I've only been at this for about 6 months and worked up this paper the other day for my friends who are interested but know very little about this. Hopefully whoever reads this can make in corrections as I am far from an expert.
Blockchain
Cryptocurrency, Bitcoin, Ether are all blockchains. Blockchains are basically a spreadsheet (LEDGER) that is duplicated multiple times across a network and updated regularly simultaneously. There is no centralized version of this ledger. It is hosted simultaneously by thousands/millions of computers. These ledgers will update on their own, Bitcoin as an example automatically checks itself every 10 minutes. Each of these 10-minute increment of transactions (in bitcoins case transactions would be sending or receiving bitcoins from one person to another for goods or services) are called BLOCKS. For these blocks to be confirmed, accepted, and updated to the ledger nodes are required.
Nodes (Mining/Forging)
A node is a computer running the blockchain software on the network. The blockchain software will automatically download the entire ledger of all transactions since its inception. At regular intervals, the software will take the transactions of a block (data on the ledger) and convert them into a mathematical puzzle to be solved by randomly chosen nodes (MINING). Mining requires powerful processors (typically GPUs) and substantial quantities of energy to receive mined tokens profitably. When a specific number of nodes solve the puzzle with the same answer they are basically confirming that the data on the block is accurate as multiple independent nodes found the same answer. When confirmed, the block gets added to the previous blocks making a chain of blocks aka a blockchain. As an incentive to run your computer as a node you are rewarded with TOKENS. If a single person or group of people wanted to manipulate the ledger, the amount of machinery and electricity used to achieve the majority of miners thus allowing you to manipulate the ledger is so exponentially expensive that it serves no reasonable purpose. This is an example of a Proof of Work Blockchain System (computer solves puzzle and rewarded with tokens)
Tokens
Tokens are part of the core of the blockchain. They are an incentive to validate transactions and create blocks. They gain intrinsic value based on the blockchain they are associated with. Some blockchains grant token holder’s different abilities. With Bitcoin, tokens are needed to pay for transaction fees. Others allow voting rights on how certain blockchain functions are managed. There is a limited amount of Bitcoin that will ever be released to nodes (21 million expected to be all be released by 2033) which also keep inflation from being a problem. Blockchains can create their platform with whatever number of tokens they would like and release them or create means to mine them as they see fit. Essentially, as with any other fiat money (currency that a government has declared to be legal tender NOT backed by a physical commodity), as adoption and trust increases the value of the token will increase. If most people accept Bitcoin for services and stores accept Bitcoin for goods than it is as good as the next currency.
Wallets
Whether you mine for tokens, are paid in tokens for goods or services or purchase tokens from a person or currency exchange you need a place to store them securely and a way to send and receive them. Cryptocurrency Wallets don’t store currency, they hold your public and private keys that interface with the blockchain so you can access your balance, send money and manage your funds. The public key allows others to send money to the public key only. A wallet that is "offline" (see Hardware or Paper below) cannot access funds or send money unless it is accessed with another form of wallet, either desktop, online, or mobile.
1) Desktop Wallet - Installed on your computer and are only accessible from that SINGLE computer. Very secure but if someone hacks your computer you are exposed. 2) Online Wallet - Run remotely (cloud based) and are far more convenient to access but make them more vulnerable as they are controlled by a third party and are also vulnerable to hacking attacks. Exchange wallets are online wallets but you are not in control of the private key. View it as a wallet that is lended to you so you can trade. The wallet is technically not yours. 3) Mobile - Ran on an app and are useful as they can be used anywhere including retail stores 4) Hardware - Private keys are stored on a tangible device like a USB drive. They can make transactions online but they are stored offline. Compatible with web interfaces and support many but not all currencies. To use, plug into a computer, enter a pin, send currency and confirm. Safest form of storage. 5) Paper - Basically a physical printout of your private and public keys. It is not stored online anywhere and the only way transactions can happen is if you transfer money with the help of an Online wallet.
Example of a Public Key = 1A684DbsHQKPVCWgaUsYdF4uQGwTiA9BFT Example of a Private Key = E9873D79C6D87DC0FB6A5778633389F4453213303DA61F20BD67FC233AA33262
Most wallets provide a Recovery Mnemonic Passcode that is a series of words (typically 12 to 24 words) in a specific order. If you lose your login information for your wallet you can supply the mnemonic passcode and retrieve your lost login information. If you lose your login information and your mnemonic passcode your wallet will be inaccessible and your tokens are lost to you. The above basically describes a first generation Blockchain Cryptocurrency such as Bitcoin. It is used basically as currency with no centralized entity regulating the release of additional currency and keeping the ledger of where the money is going secure and extremely safe from manipulation.
Second Generation Blockchain
The second generation blockchains sprung out of this environment with something more valuable. Utilizing the blockchain system to allow applications to be ran on top of a decentralized secure system. Instead of just recording transactions, contracts could be transmitted the same way. More complex transactions (SMART CONTRACTS) allow for things such as: - Funds to be spent only when a required percentage of people agree - Manage agreements between users (such as insurance) - Provide utility to other contracts - Store information about an application such as domain registration information or membership records This basically can allow applications to be ran on top of the blockchain system. This can cut out the middleman for many real-world applications (mortgages, banking, communications, security confirmations etc.)
Proof of Work/Proof of Stake
As I mentioned earlier, Proof of Work (PoW) requires nodes to solve a mathematical puzzle which is rewarded with tokens. Proof of Stake (PoS) is different, the tokens with proof of stake systems are pre-mined meaning they are all created when the blockchain system is created. Blocks are not verified by the typical method. The block validator uses the blockchain software to stake their tokens and are chosen based on specific factors depending on how many tokens the person holds and for how long. Depending on how many tokens they hold will restrict the quantity of blocks they can validate. If they own more they can validate more often but all validators will be chosen randomly keeping the rewards fairly distributed (unlike PoW which typically reward the first completed.) The blockchain still requires a mathematical puzzle to be solved but it is much easier than PoW requiring far less time and energy. If the blockchain has premined all of their tokens then new tokens cannot be mined for rewards in PoS. The reward for staking your tokens to be a validator is a portion of the transaction fee that is charged as part of normal transactions on the blockchain. That is why PoS miners are called forgers. If manipulation is attempted than their stake can be taken from their wallet adding more motivation to prevent data manipulation.
Fork
Some cryptocurrencies may need to update or upgrade the coding of their blockchain software. When this happens usually a fork occurs. This basically means the cryptocurrency splits into two separate cryptocurrencies. Because the nature of blockchain technology, they are decentralized and autonomous so the older version cannot be deleted or removed. If people choose to continue using the old version they can. For mining/forging purposes the nodes will need to choose which they will mine/forge and download the blockchain software on their computer to proceed. When the fork occurs, anyone holding tokens in the original currency will be given the same number of tokens in the forked currency. (When Bitcoin forked to Bitcoin Cash, anyone holding x amount of Bitcoin would receive a new wallet for Bitcoin Cash also containing x amount of Bitcoin Cash.) This is called a Hard Fork and all previous transactions are made invalid. There are also Soft Forks, in this case it is backwards compatible and all previous transactions are valid. This can result in two currencies but in most cases, it doesn’t as it is usually accepted by most miners/forgers because it is backwards compatible.
Exchanges
Online currency exchanges allow you to buy, sell or exchange fiat money (USD, EUR, etc) with digital currencies or in most cases digital currencies for other digital currencies. There are a large variety of different exchanges that are operated in multiple countries but there are around a dozen that the majority of cryptocurrency trading volume are present on. Not all cryptocurrencies will be listed on all exchanges, some have specific prerequisites to be listed on their exchange and there may be fees associated as well. Once your account is set up you will have a list of all available cryptocurrencies to trade. Each currency will have an associated online wallet with the public key address allowing you to send that specific currency to that wallet. (Many exchanges are having delayed or canceled identity verification, currency transfers and lack sufficient customer support due to the influx of new traders) Examples of top exchanges: 1) Coinbase (trades fiat) 2) GDAX (trades fiat) 3) Gemini (trades fiat) 4) Changelly (trades fiat) 5) Bittrex 6) Binance 7) HitBTC 8) EtherDelta 9) Bitfinex 10) Kraken 11) Bithumb 12) Bitstamp 13) Poloniex 14) OKEx
Sending/Receiving Tokens
All wallets have the ability to send digital currency to other wallets. The function is relatively easy, make sure the currency you are sending is going to the appropriate wallet for that currency. Ethereum tokens cannot be sent to a Bitcoin wallet for example. (The tokens aren’t actually moving location; the list of transactions/ownership is what is stored in the wallet). Triple check the wallet private key you are sending the tokens to. If you type the wrong address the tokens will be lost in nearly all incidents. Some mobile wallets allow you to scan a QR code that will automatically enter the public key rather than copying/pasting or typing out the public key.
Taxes
As of January 1, 2018 it appears that taxing on digital currency has changed. Every trade between any digital currencies (Bitcoin to Ether, Ether to Litecoin etc) will be a taxable transaction. If you hold the currency for longer than one year than you will pay capital gain tax when it is traded or sold (15%-20%) and if you sell or trade in less than a year you will have to add the profit to your taxable income to adjust your tax bracket.
Altcoins
Altcoins are basically any coin that is not Bitcoin. Most cryptocurrencies do not have a native blockchain (their own independent dedicated blockchain). Bitcoin, Ether, Ripple, Waves, NXT, Cardano all have their own native blockchain. Many other cryptocurrencies run on other cryptocurrency’s blockchains. Litecoin runs on Bitcoins blockchain, hundreds run on the Ethereum blockchain. These currencies act as smart contracts running on the adopted blockchain.
DApps (Decentralized Applications)
For a blockchain application to be considered a DApp it must be 1) Open source, code available to all 2) Decentralized, uses blockchain cryptographic tech 3) Incentive, must have tokens to fuel itself 4) Algorithm/Protocol, generates tokens and has a built-in consensus mechanism (mining/forging.)
There are 3 types of DApps, each basically piggybacks off the platform of the previous Type 1 – Have their own blockchain (like bitcoin) Type 2 – Use the blockchain of Type 1 DApps Type 3 – Use the protocol of Type 2 DApps
ICO (Initial Coin Offering)
Much like an IPO (Initial Public Offering) that offers stock in a private company to the public, an ICO raises money for new Cryptocurrency ventures. Typically, a minimum investment is required in the form of a cryptocurrency such as Bitcoin or Ether and the investor is given tokens of the cryptocurrency at a reduced cost. Due to the fact that ICO’s are so new, government agencies have not begun regulating these ventures making them extremely risky as anyone with a competent coder can create and market a cryptocurrency that can be used to swindle investors who aren’t cautious. The US government no longer allows its citizens to participate in ICO’s and if you are using a computer with an IP address located in the United States, ICO’s websites will not allow you to invest.
Research
1) Whitepapers – Each cryptocurrency will have their own dedicated websites and most will have a whitepaper that has a description of what their cryptocurrency is designed to do. 2) Roadmaps – Also on each cryptocurrency’s website, they tend to have a roadmap or timeline as to when they are planning to complete certain milestones be it added features to the blockchain or wallet or any other important events. 3) Coinmarketcap.com – List of every available cryptocurrency, the exchanges they trade on, market cap, trade volume, available tokens, newly created tokens etc. 4) Reddit.com (cryptocurrency subreddit) – Subreddits focused on cryptocurrency as well as specific subreddits focused on individual cryptocurrencies. Be cautious as many people on these sites are uninformed and/or are trying to manipulate the market by fooling others to buy or sell based on fraudulent information. 5) Bitcointalk.org – Forums specific to individual cryptocurrencies. There is a lot of self-marketing (bounties) on this site. Take what they say with a grain of salt 6) TwitteFacebook (Social Media) – Many times news from team members or the cryptocurrency’s social media page will break news before it is listed on any of the above-mentioned outlets. Find out who is working for the cryptocurrency you are interested in and start following the team’s social media. Don’t forget to look at their linkedin accounts if available, previous employment and behavioral history to confirm they are competent. 7) Github - Code from projects can be uploaded here and reviewed for issues and revisions.
Common Terms/Slang
Shilling – covert advertising, personally endorsing a token so as to manipulate the price to either recoup a loss or increase gains on a token the individual owns. FUD – Fear, Uncertainty, Doubt; another method to manipulate the price of a token the person owns by making others second guess their investment decision on a specific token. FOMO – Fear Of Missing Out; buying a token (usually after the price has already increased) hoping they haven’t missed the majority of a price increase. Shitcoin – A cryptocurrency that has become worthless overtime or a scam operation. To the Moon – Massive increase in a token’s price.
I'm sure there are probably revisions to be done on this as I am still getting my head around all of the concepts. Any help to this would be appreciated.

Crypto Wallet

Crypto Wallet Guide
Humans have come a long way from the barter trading (trading goods without using the money) to gold, then later to paper currency and now we have arrived in the age of digital currency.
There are more than 2000 cryptocurrencies in the world with a market capitalization of around $175 billion, it is necessary to know about them. Where these currencies are stored? How does the crypto wallet work? If You are still reading this, it says you are a beginner and want to explore the crypto world.
To understand the crypto concept, first, know about the crypto wallets.
What Is Cryptocurrency Wallet?
A cryptocurrency wallet is a software program used to store, send, receive private and public keys and can be used to track ownership. It enables you to send and receive digital coins through blockchain. Wallets are a necessary factor for investing and owning cryptocurrencies of any sort.
However, Some wallets are built for a single cryptocurrency( bitcoin and coins forked from bitcoin like bitcoin cash), some can be used for more than one coin(multi cryptocurrency wallet), some wallets you’ll manage yourself, and some will be custodial.
What Are Public & Private Keys?
A public key is a unique identifier for a person and a private key is like a password similar to an ATM pin. A sender will require the public key of the receiver to send him the cryptocurrency and the receiver will be able to access and use these cryptocurrencies by using the private key. A private key must be protected in order to avoid fraudulent activities such as hacking, stealing of cryptocurrencies, etc.
A public key can be extracted from a private key, but a private key can never be extracted from a public key.
A private key should always be kept safe. Exposing it would be vulnerable for various hacks and stealing of the coins by with whom you have shared. sending them to another wallet which they control.
Example of a private key: N2nGYRCBbs6ZRs8w5LHam4r85ikxBzhRNgpNJjqk7D5vrpuaVJB
Example of a public key: 958ikZuaAbGkzXuFL9sfGHYj9ethop8qMh
How Does a Cryptocurrency Wallet Work?
Cryptocurrency wallets work like the safety deposit boxes. Unlike traditional pocket wallets, where they don’t store digital currency. The crypto wallets store your private and public keys and interface with multiple blockchains. Thus, users can track their balance, send money and conduct other operations.
Moreover, currencies don’t get stored in any single place. Also, it is advised not to store the cryptocurrencies on the wallet offered by the particular exchange, because the exchange will own your private key. So better you transfer it to your own crypto wallet to have control over the cryptocurrencies owned by you.
A wallet address is the same as a bank account number. Providing your bank account number to other people, as they need it to transfer your funds. For example: This is like your friend transferring you money, so he needs your bank account number.
In the world of cryptocurrency, if anyone wants to transfer you crypto coins, you should provide him with your wallet address. Similar, like in the real world, however, no two wallets can have the same address, which means that there is no risk of your fund being to transfer to others address. Moreover, there is no limit to the 5number of wallet addresses you create.
Different Types of Crypto Wallets
There are multiple types of wallets that provide different ways to store and access your digital currency.
Hot Wallets vs Cold Wallets
you might come across frequently with the terms “hot wallets” and “cold wallets”. All crypto wallets fall under these two types.
In general, whatever is connected to the internet is less secure than something that is not. This is the difference, where “hot” wallets are connected to the internet and “cold” wallets” are not.
Online, desktop and mobile wallets are hot wallets, while hardware and paper wallets are cold wallets.
1). Software Wallet:
There are three forms of software wallets:
Desktop wallets: These are installed on a laptop or a PC, and can be accessed from a single computer. Although they provide high security, if the computer is attacked by the virus, there is a chance of losing your wallet.
Online wallets: These wallets run on the cloud and can be accessed from any device. Here, your keys are stored online.
Mobile wallets: These wallets that run on an application in a smartphone; they are simpler than the desktop wallets and can be used anywhere.
2). Full Node Wallet:
Here you can control your private keys and provide a full copy of the blockchain. Essentially every coin has an official wallet of this type and that can be found on the official GitHub of the site. “Official” means endorsed by the developers who created the coin.” Many cryptos are decentralized, so there is no real official anything.
3). Coin-Specific:
A wallet which works only with a specific coin.
4). Network-Specific:
A wallet which can hold multiple tokens on a single network.
5). Hardware Wallet:
These type of hardware are specifically built to hold cryptocurrency and keep it safe. This includes USB devices. Moreover, these devices can go online to make transactions and get data and then can be taken offline for transportation and security.
6). Paper Wallet:
This type of wallet lets you to both send and receive digital currency using a paper wallet. You can take a print of your QR code for both a private and public key. With this feature, you can completely avoid storing digital information about your currency by using a paper wallet.
7). Custodial Wallet:
In Custodial wallet, you can’t control your keys directly. Most exchange wallets are custodial wallets.
8). Multisignature Wallet:
It requires multiple parties to sign a transaction for any digital money to be spent. Multisignature wallets are designed to have more layer of security.
How To Choose a Wallet?
Here are some ideas on how to choose the best wallet for you.Hardware and paper wallets are the best to secure funds. Also, We always suggest official or officially endorsed wallet for any given coin.
Ledger Nano S: Multi-currency support, Built-in Display, Easy to operate, Security, Backup and restoration.
Ledger Blue: Malware proof, Multiple currencies, Secure elements.
Jaxx: Exclusive design, Easy to use, Personalized key, available on multiple OS.
Edge wallets: Security, Multi-Currency Support, Easy to use.
Exodus : Multi-currencies, Complete security, Great design, Multi-currencies.
Coinpayment: Bit-go integrated, Online store acceptable, vault, multi-coin wallet.
Most top performing wallets are (Binance, Coinbase, etc.) and they have exchanges too that offers for easy and quick trading between Bitcoin and other crypto or bitcoin and fiat currencies.
Online wallets are prone to security hack and therefore should be used as little as possible. It will be safe to divide your funds among the different types of wallets.
How to Register in a Wallet?
If you are a newbie to the crypto world, then read these points before proceeding:
Download the official wallet from the website.
Register for a custodial wallet service ‘Coinbase’ or non-custodial wallet service like ‘Blockchain’ Wallet (which handles both wallet and exchange with one account).
Purchase a hardware wallet like TREZOR for storage.
Use a universal software wallet or any other wallet that meet your needs like the ones mentioned above.
Coinbase and TREZOR are one of the good major choices, since, they have guides and can be kept safe with the best execution, and also, don’t need to download the full blockchain for a coin.

Cryptocurrency Terms And Definitions - Common Crypto Words To Know

The blockchain community is not left out when it comes to the use of jargon and phrases. The use of words that look strange to those who are not involved in crypto is totally inevitable. It’s definitely going to be difficult for anyone not in this space to understand words like “ERC20, ICO or gas. So in order to help such people out, we have made a list of the most common cryptocurrency terms and definitions. Please sit back and enjoy your ride.

Cryptocurrency Terms And Definitions
One can categorize these terms into various parts. First of all, we will deal with general cryptocurrency terms and definitions.

Blockchain
Blockchains are distributed ledgers which are secured by cryptography. Everyone has access to read the information on every blockchain which means they are essentially public databases but the data update can only be done by the data owners. In the case of blockchains, data doesn’t remain on a single centralized server, they are copied across hundreds of thousands of computers worldwide. Projects such as Ethereum, Vechain, EOS etc. fall under this class of technology.
Mining: The means of trying to ‘solve’ the next available block. One needs huge amounts of computer processing power to carry this out effectively. There is always a reward for doing this.
Mining rig: A specially designed computer that processes proof-of-work blockchains such as Ethereum. They consist of multiple high-end graphic processors (GPUs) so as to maximize their processing power.
Node: This is a computer that has a copy of the blockchain and is working to keep it in a good shape.
PoW: The full meaning of this is Proof-of-work. The Ethereum network currently makes use of this algorithm.
PoS: Its full meaning is Proof-of-stake. It is the proposed future algorithm for Ethereum. Those that own ETH will be able to lock up all or a portion of their ether for a given amount of time in order to ‘vote’ and generate network consensus instead of mining in its current form. Stakeholders will get rewards in form of ETH by doing so.
Fork: This takes places when a certain blockchain splits into two different chains. This usually happens in the crypto space when new ‘governance rules’ are infused into the blockchain’s code.
Software wallet: A crypto-currency storage that exists purely on a computer as software files. You can generate these kinds of wallets for free from diverse sources. MyEtherWallet (MEW) is one of the most popular sources around.
Hardware wallet: A device that one can securely keep cryptocurrency. People often say that these wallets are the most secure way to store cryptocurrency. Examples of the most common hardware wallet models around are Ledger Nano S and Trezor.
Cold storage: This is a way of moving your cryptocurrency from an online wallet to an offline one, as a means of safekeeping them from hack. There are a lot of ways to carry this out. Some methods that are commonly used include:
· Using a hardware wallet to store your cryptocurrency.
· By printing out the QR code of a software wallet and keeping it somewhere which is safe.
· You can also move the files of a software wallet onto an external storage device such as USB drive and keeping it somewhere safe.

Trading Related Cryptocurrency Terms And Definitions
Exchange: These are websites where people trade (buy and sell) their cryptocurrencies. Some of the popular crypto exchanges we have around include Binance, Poloniex, Bittrex etc.
Market order / market buy / market sell: A sale or purchase which is made on an exchange at the current price. A market buy acquires the cheapest Bitcoin available on the order book while a market sell fills up the most high-priced buy order on the books.
Limit order / limit buy / limit sell: These are orders which are placed by traders to buy or sell a cryptocurrency when the price reaches a certain amount. They are pretty much like ‘for-sale’ signs you see on goods.
Sell wall / buy wall: Cryptocurrency traders are able to see the current limit buy and sell points using a depth chart. The chart’s graphical representation is very much like a wall.
FIAT: Refer to a government-issued currency. An example is the US dollar.
Whale: A person who owns huge amounts of cryptocurrency.
Margin trading: This is an act of increasing the intensity of a trade by using your existing coins. It is very risky for an inexperienced trader to partake in this. Stay safe!!
Going long: This is a margin trade that gives profit if the price goes up.
Going short: It is a margin trade that gives profit if the price goes down.
Bullish: Being optimistic that the price of cryptocurrency is going to increase.
Bearish: This is an expectation that the price of cryptocurrency is going to decrease.
ATH: This simply means All-Time-High. This is the highest point that has been reached by a particular coin or token. Take for instance, Bitcoin’s ATH is about $20,000 and this was achieved around December 2017 and January 2018.
Altcoin: A word used to qualify other cryptocurrencies which is not Bitcoin. Examples of altcoins are Ripple, NEO, EOS, Vechain, Electroneum etc.
Tokens: These are ‘currency’ of projects which are hosted on the ethereum network. They raise money by issuing their own tokens to the general public. Tokens have a significant use in the project's ecosystem. Examples of tokens are Enjin Coin (ENJ), Zilliqa (ZIL), OmiseGO (OMG), Augur (REP) etc.
ICO: The full meaning is Initial Coin Offering. This is synonymous to an IPO in the non-crypto world. Startups give out their own token in exchange for Bitcoin or ether.
Shilling / pumping: An act of advertising another cryptocurrency. It is mostly done in a way that tricks as many people as possible into believing that a coin or token will get to a higher price in the future.
Market Cap: This is the total value of a cryptocurrency. To calculate this, one has to multiply the total supply of coins by the current market price. You can get a run-down of several cryptocurrency projects on Coinmarketcap.
Stable coin: This is a cryptocurrency which has an extremely low volatility. You can use a stable coin to trade against the overall crypto market.
Arbitrage: A situation where a trader takes advantage of a difference in the price of the same coin / token on two different exchanges.
FOMO: Simply means Fear Of Missing Out. That overwhelming feeling that one needs to get on board when there is a massive rise in the price of a commodity. This is also applicable in the crypto space.
FUD: Fear, Uncertainty, and Doubt. It is a baseless negativity which is spread intentionally by someone or a group of people who want the price of cryptocurrency to decrease.
FUDster: A person who spreads FUD.
Pump And Dump: This happens when an altcoin gets a ton of attention, leading to a massive increase in price, and likewise followed by a big price crash of that altcoin.
ROI: Return on Investment. The percentage profit a trader makes on an initial investment (i.e. A 100% ROI simply indicates that a trader doubled his money).
TA: Trend Analysis or Technical Analysis. A way of examining current coin charts so as to make predictions for the next market movement.

Next, we will be moving on to crytocurrency terms and definitions that are ethereum related.
Dapp: Decentralized Application. It is an application that uses a decentralized peer-to-peer network like Ethereum smart contract as its back-end code.
Bagholder: A person who still holds on to a particular altcoin despite having a pump and dump crash.
Smart contract: This is a code that is deployed onto the Ethereum blockchain, it often helps with the direct interaction of how money flows from one point to another.
The Flippening: A future event showing the capacity of Ethereum’s market cap (or some other cryptocurrency) surpassing Bitcoin’s market cap, making Ethereum the most ‘valuable’ crypto-currency.
Gas: It is a measurement of the amount of processing needed by the ethereum network to execute a transaction. More complex transactions like deploying a smart contract onto the network requires more gas than sending ether from one wallet to another which is obviously a simpler operation.
Gas price: This is the amount of ether an initiator of a transaction is willing to spend for each gas unit on a transaction. The higher the gas price, then the faster the processing of the transaction.
Wei: It is the smallest denomination of ether.
Gwei: This is a denomination of ether (ETH). Gwei is the unit for measuring gas prices. 1 Ether = 1,000,000,000 Gwei (109).
MEW: MyEtherWallet is a site where users can generate ethereum wallets for free.

We also have a handful of cryptocurrency terms and definitions that are memes. See some of them below;
Hodl: People use this word when signifying that a person is keeping his coins / tokens for a long period of time. A couple of years back, someone on a Bitcoin forum made a post with a typo HODL in place of HOLD. Ever since then, this term has become one of the most popularly used term in crypto.
Mooning: In crypto, this term comes to play when the price of cryptocurrencies move up astronomically.
Lambo: This is highly synonymous with crypto. You can't leave out this word when discussing about cryptocurrency terms and definitions. This is the car we’re all goona buy when crypto makes us rich.
This is gentlemen: People use this phrase when pointing out positive things that are currently taking place in the cryptosphere.

Now that you are conversant with some of the commonly used cryptocurrency terms and definitions, you can now go out there and showcase your new crypto vocabulary to the world.

A detailed simple guide for Pundi X in Spanish language.

Website; https://www.bitcobie.com/pundix/
Extracted from site below;
¿Qué es Pundi X?
Comprar criptomonedas debería de ser tan fácil como comprar una botella de agua. Esta frase es el eslogan oficial de Pundi X y no hay una frase que defina mejor al proyecto ni el camino que deben coger las criptomonedas para llegar a una adopción masiva.
A principios de 2018, justo cuando se empezó a desinflar el mercado tras el espectacular rally del 2017, Pundi X cumplía con las expectativas y consigue recaudar en su ICO 35 millones de dólares en apenas 90 minutos.
No era para menos ya que Pundi X puede convertirse en una pieza clave para el éxito de todo el ecosistema blockchain. Lo interesante de este proyecto es que se puede convertir en el puente perfecto para que el resto de las criptomonedas lleguen a billones de personas que de otra manera tardarían mucho más en conocerles.
Comprar criptomonedas debería de ser tan fácil como comprar una botella de agua.CLIC PARA TUITEAR
Las aspiraciones de esta ambiciosa empresa son el desplegar una gigantesca red de puntos de venta con la que facilitarían el acceso a la criptoeconomía a entusiastas, comerciantes y cada vez a más usuarios para así llegar lo antes posible a una plena adopción de las criptomonedas.
Este proyecto de origen indonesio nace también con un gran propósito, que es el de dar acceso a servicios financieros a la población desbancarizada de indonesia que es una inmensa mayoría. Ese mismo modelo lo podrán replicar en zonas de África y Sudamérica, sin duda es un nicho de mercado prácticamente infinito.
Pundi X ofrecerá también a los usuarios un monedero simplificado y es que la fortaleza de este proyecto es la debilidad de muchos otros, la larga y costosa curva de aprendizaje del usuario medio es lo que pone más barreras a la entrada de nuevas personas al criptomundo, con Pundi X esta curva se hace mucho más pequeña y llevadera.
¿Quién es quien en el equipo de Pundi X?
Para mucha gente el equipo de Pundi X es de los más activos que existen y el trabajo en el proyecto es constante, además de eso es un equipo muy abierto a la comunidad y lo han demostrado con numerosos ejemplos en los que se han atendido peticiones de los usuarios en beneficio del proyecto.
Su CEO y cabeza visible es Zac Cheah, formado en diversas universidades tecnológicas y con una amplia experiencia en el ámbito de los videojuegos, ha trabajado en Google y en Opera. No duda en moverse por todo el mundo para mostrar las posibilidades de Pundi X a curiosos e inversores.
Pitt Huang es su CTO/COO, emprendedor desde muy temprana edad vendió su primera empresa a los 25 años, es un apasionado de los gadgets y una figura muy importante para PundiX, igual que su presidente Constantin Papadimiriou, que cuenta con una dilatada experiencia en el ámbito del Fintech.
El CFO de PundiX, Danny Lim, es un experto financiero con experiencia laboral en Lenovo o Baidu. El equipo lo cierra David Ben Kay, que es el encargado de que todos los ámbitos legales y normativos se cumplan. David estuvo dentro de la Ethereum Foundation, en Microsoft China y se graduó en la universidad de UCLA.
Este equipo se complementa con una infinidad de embajadoresrepartidos por todo el mundo que hace una labor diaria de acercamiento a la comunidad, recientemente se ha nombrado a Joao Victor representante de PundiX en Latinoamérica, a Liko Yosafat como una de las personas más activas dentro de Pundi X o a Gerhard Drobits, responsable de PundiX en Europa.
¿Cuales son las alianzas de Pundi X?
La naturaleza del proyecto de PundiX permite que para los grandes actores del criptomundo les sea muy atractivo remar al costado de este gran proyecto. Ahora mismo entre las filas de asociaciones con PundiX se encuentran empresas como Binance, Nem, Verge, Qtum, Stellar, Achain, ZCash, Utrust o Fintech Indonesia entre muchos otros.
Se rumorea también por internet que Pundi X pudiese tener entre parte de sus advisors a gente de McDonalds Indonesia o Nike, de eso no hemos podido confirmarlo así que lo dejaremos como un simple rumor, pero sin duda es cuestión de tiempo que grandes empresas se sumen a la revolución de las criptomonedas.
¿Qué es NPXS?
NPXS es el actual token de Pundi X, un token ERC20, funciona en la blockchain de Ethereum y es el gas de la plataforma PundiX y el que garantiza su funcionamiento.
En un principio el token de Pundi X era PXS, pero tras recibir innumerables peticiones por parte de la comunidad de realizar una fracción mayor del mismo la comunidad decidió realizar un swap, en el que el usuario que enviaba un PXS recibiía 1.000 NPXS. De esa manera las métricas de Pundi X se convirtieron en algo más coherente para el correcto funcionamiento del XPOS, la joya de la corona.
Es muy importante que conozcas la naturaleza real del token NPXS, ya que no fue ideado para convertirse en un medio de pago, si lo fue Pundi X, el token NPXS es la gasolina del XPOS y el elemento con el que se podrá interactuar tanto con la empresa como con las funciones del punto de venta.
Podrás observar que el número total de tokens de Pundi X es bastante mayor que el de la mayoría de criptomonedas, algunos eso lo ven como un freno a una subida considerable de su precio, pero la realidad es que si el supply fuera más bajo quizás se quedaría corto una vez desplegada toda la rede de puntos de venta, que es el propósito por el que trabaja el equipo de Pundi X.
¿Cómo funciona el airdrop de Pundi X?
Mucha gente llega a este proyecto por su airdrop y es que parte de la distribución planteada por Pundi X en su Whitepaper es la de desbloquear los tokens en beneficio de sus holders progresivamente todos los meses, así quedó fijado que durante el 2018 se daría cada mes un 7,316% sobre los tokens que hubiese en cada wallet de Pundi X, incluso estando en la mayoría de exchanges, aunque no en todos en los que se pueden negociar.
Este porcentaje se reducirá en 2019 al 2,11637% y al 0,88187% a partir de enero del 2020, dando por finalizada la distribución del token de Pundi X el 31 de enero de 2021.
Este sistema que a priori es muy atractivo para el poseedor de Pundi X a largo plazo se convirtió a mediados de 2018, en pleno mercado bajista, en un arma de doble filo para el holder ya que la sencillez de obtener los tokens atrajo a más especuladores de los que podría soportar el proyecto.
El sistema de distribución antiguo solo requería tener tokens de Pundi X tres horas antes del snapshoot y tres horas después. Esa cantidad es la que determina cuantos tokens tenía tu wallet y acto seguido al cabo de unos días recibías tu recompensa por aguantarlos.
Este sistema provocó que un gran número de personas compraran masivamente NPXS antes de la foto y vendieran inmediatamente después ya que una vez hecha esta, recibirían igualmente los tokens que les corresponde, esos tokens por supuesto se vendían nada más llegar para arañar BTC o ETH, convirtiendo a Pundi X en un “proyecto escalón” vapuleado por grandes especuladores que perjudicaban al fiel holder de Pundi X.

Revisando el sistema de distribución de tokens
Una vez más el equipo decidió escuchar las numerosas peticiones de revisar el sistema de distribución de los tokens de PundiX y propuso a votación en agosto del 2018 un nuevo sistema, que, aunque no es totalmente perfecto, es inifinitamente más justo con el holder de Pundi X que el anterior.
El nuevo sistema hace una media de los tokens que tienes durante todo el mes en tu monedero, de tal manera que para recibir el 7,316% total de 1 NPXS este tiene que estar 30 días en tu poder, de no ser así te corresponde la parte proporcional a los días que lo hayas guardado. La nueva formula es la siguiente:
(La cantidad más baja de tokens NPXS del mes X 10%) + (la cantidad promedio diaria de NPXS X el resto de los días de retención X 90%)
Para que lo entiendas mejor, te planteamos tres ejemplos:
Ejemplo 1:
Imagina que a principio de mes tienes 2.000 NPXS, decides vender 1.000 NPXS el 15 de agosto y vuelves a comprar 1.000 el 30 de agosto. Realmente solo hay dos transacciones en tu monedero ese mes y el número de tokens es el mismo al final de mes, pero durante 14 días sólo has tenido 1.000 NPXS, por lo tanto:
(1000 x 10%) + {[(2000 x 14 días) + (1000 x 14 días) + (2000 x 2 días)] / 30 días} X 90% = 1480
Los tokens desbloqueados que recibirás serán alrededor de 108 NPXS (1480 X 7.316% = 108)
Ejemplo 2:
Si no tenías ningún NPXS a principio de mes y decides comprar 2.000 NPXS el 30 de agosto, sólo has tenido tokens de Pundi X 2 días, por lo que entiende la comunidad que no es justo que recibas lo mismo que alguien que los ha tenido todo el mes, por lo tanto con el nuevo sistema el calculo sería:
(0 x 10%) + {[(2000 x 2 días + 0 x 28 días) / 30 días] X 90%} = 120
120 X 7.316% = 8
Los tokens desbloqueados que recibirá serán aproximadamente 8 NPXS.
Ejemplo 3:
Si el número de tokens de tu monedero no varía en todo el mes, es decir tienes 2.000 NPXS y no haces ningún movimiento lo que recibirás es lo siguiente:
(2000x 10%) + [(2000 x 30 días) / 30 días] X 90% = 2000
2000 X 7.316% = 146
Recibirá alrededor de 146 NPXS
Reparto equitativo de tokens
Como puedes observar este sistema reparte de una manera equitativalos tokens en función a los días que los mantienes en la cartera, por lo tanto si tu idea es acumular y recibir el total del airdrop mensual es importante que compres los tokens antes de las 23:59:59 SGT (GMT+8) del último día de mes, para recibir el mes siguiente el porcentaje total de la distribución de tokens de Pundi X.
Este reparto entrará en funcionamiento a partir de septiembre del 2018, el equipo aún no sabe si por dificultades técnicas las casas de cambio harán correctamente ese reparto por lo tanto recomiendan fervientemente mantener los tokens de Pundi X en una wallet ERC20 en la que tengas el control de tus claves privadas.
En un nuevo comunicado el equipo ha anunciado el día 28 de agosto del 2018 que los exchange Binance y OkCoin Korea soportarán el nuevo sistema de airdrop.
(Nosotros en Bitcobie te lo recomendamos inclusive si los exchanges hiciesen el reparto correctamente ya que, sin control de tu clave privada, no tienes realmente nada)
Cómo invertir en PundiX sin morir en el intento
PundiX actualmente es un token ERC20, por lo tanto, funciona en la blockchain de Ethereum y como todos los tokens ERC20 se puede almacenar en una wallet compatible con esa tipología de tokens. Por lo cual, el primer paso que tienes que realizar es el de elegir bien donde vas a almacenar tus NPXS.
El equipo de Pundi X (y Bitcobie) te recomienda fervientemente que almacenes tus tokens NPXS en una wallet en la cual controles las claves privadas, bien puede ser en MyEtherWallet, usando la interfaz de Metamask o en tu Ledger Nano, siempre en función a la seguridad con la que quieras trabajar.
Lo que no es recomendable y no sólo por no recibir correctamente el airdrop con el nuevo sistema, es almacenarlas en un Exchange. No olvides que si lo haces de esa manera no tendrás el control de tu clave privada por lo tanto serás vulnerable a los hackeos de estas páginas pudiendo perder todos tus fondos.
Una vez elegido el recipiente es importante que te hagas con Bitcoin o Ethereum para intercambiarlo por Pundi X, actualmente no hay ninguna casa de cambio que acepte el cambio directo entre Pundi X y dinero FIAT. Para eso las opciones recomendadas suelen ser Coinbase, Localbitcoins o si resides en España, Bit2me, una página que realmente pone muy fácil al usuario el acceder a sus primeras criptomonedas.
La verdadera revolución de Blockchain llegara cuando mejore al menos 10 veces lo que tenemos hasta ahora.CLIC PARA TUITEAR

Cuando tengas la cantidad deseada de Ether o Bitcoin, deberás mandarlos a la casa de cambio de tu elección que permita el intercambio de esas criptomonedas por Pundi X, actualmente puedes hacerlo en: Binance, Latoken, Hotbit, Coinnest, Bitbns, CoinBene, Coinrail, Gate.io, Tidex, Tokenomy, Bit-Z y Radar Relay (por orden de volumen diario)
Una vez hecha tu compra llega el momento de decidir enviarlos o no a la wallet que has escogido previamente, nuestra recomendación es que te fijes siempre en las comisiones que te vayan a cobrar las casas de cambio, hay ocasiones en que, si la cantidad adquirida es muy pequeña, la comisión se come demasiada parte del lote.
Si tu idea es tradear con Pundi X, lo mejor es que lo mantengas en el Exchange de tu elección para poder disponer de ello cuando sea necesario, aunque si ese va a ser tu camino, a partir de septiembre podemos decir que el airdrop para ti será totalmente testimonial ya que buscarás beneficios por otra vía que no es la del holder.
¿Qué es NPXSEM y en qué se diferencia de NPXS?
Este punto es delicado para algunos de los inversores de Pundi X, pero nada más lejos de la realidad. Pundi X llegó un acuerdo con NEM para desarrollar también sus XPOS en la blockchain de NEM, este acuerdo implica la distribución de 20.000 dispositivos en tres años (las previsiones para Pundi X son de distribuir al menos 100.000 dispositivos en tres años)
Esta versión del token no divide al proyecto ya que el proyecto siempre ha sido NPXS, en el caso de NEM es simplemente un cliente del proyecto, ya que toda la investigación y desarrollo del equipo de Pundi X se centra en NPXS. Además, todas las funciones del XPOS se realizarán con NPXS y el uso del XPOS basado en NEM también quemará tokens NPX.
Si has llegado aquí para saber de uno y de otro proyecto, lo que tienes que tener claro es que el que actualmente tiene más volumen, más equipo, más distribución y mayor proyección es NPXS, el otro token es independiente de los logros del primero.
La blockchain de Pundi X, f(x)
Uno de los anuncios más importantes de Pundi X desde su lanzamiento ha sido el de su futura blockchain. Una vez lanzada Pundi X dejaría de depender de la red de Ethereum o Nem, y pasaría a ser un agente muy poderoso en el criptomundo y teniendo en cuenta las aspiraciones de convertirse en el puente entre el mundo real y el criptomundo, era necesario dar un paso así.
Internet cambió por completo todas las capas del mundo. El TCP/IP se convirtió en el estándar de comunicación y empresas como Cisco o IBM fueron las encargadas de colocar las tuberías y engrasar la maquinaria que ejecutaría esos protocolos. Internet propició un mecanismo de información tan rápido que han permitido a Google, Facebook o Amazon terminar prácticamente con la industria tradicional de comunicación e información. ¿Puede blockchain convertirse en el próximo internet?
Zac Cheah, CEO de Pundi X Labs, ve la revolución de blockchain en tres fases. Bitcoin fue la carta de presentación al mundo de lo que eran las criptomonedas. Ethereum nos enseñó como construir activos descentralizados, los miles de altcoins que conocemos. La tercera fase de la revolución es lo que tantas compañías Blockchain anhelan, llevar el rendimiento de la cadena de bloques a un nivel completamente superior al de la industria tradicional e internet.
Para llegar a ese punto, es necesario que blockchain mejore al menos 10 veces lo que tenemos hasta ahora. En otros momentos revolucionarios, Disquetes, VHS, fibra óptica, han demostrado que esa mejora es esencial en la ecuación si se pretende cambiar un estándar.
Velocidad x10
Actualmente Visa puede ejecutar entre 7.000 y 20.000 transacciones por segundo, TPS. Cualquier cadena de bloques que ofrezca pequeños múltiplos de mejora no desplazará un sistema tan robusto como el de Visa o MasterCard. Una mejora de 10x significa que tendríamos que conseguir 200.000 TPS. Hay varias compañías que pretenden conseguir ese punto, incluso algunas dicen haberlo conseguido, al menos sobre el papel.
PundiX pretende conseguir esa mejora no sobre su whitepaper, sino en aplicaciones reales, ya que de otra forma el resto sería palabrería. La pregunta entonces es si Pundi X puede llegar a esos números o superarlos de manera realista.
Habría que analizar por puntos. El sharding es el proceso de dividir una red global en partes de una red local. Cada red local se hace cargo de un consenso de dos tercios para que una transacción en particular se verifique en la red local para luego transmitirse a la red global.
Esto es uno de los métodos en el que las compañías de blockchain están trabajando muy fuertemente, Pundi X es una de ellas ya que uno de los problemas actuales es que si una blockchain actualmente tiene 21 nodos (por ejemplo) y tarda un segundo para confirmar una transacción, en el momento en el que tenga 210 nodos, tardará 10 segundos en verificar por consenso esa transacción.
Por lo tanto, Pundi X pretende convertir en un nodo cada XPOS que distribuya, de esa forma con el Sharding, conseguiría tener una blockchain con 100.000 nodos, que mediante el sharding conseguiría una velocidad de TPS envidiable.
Escalabilidad x10
Cuanto mayor escalabilidad, más negocios se pueden tener. En blockchain eso está más patente que nunca, en este caso dependemos del código y de los nodos. Actualmente Ethereum es la blockchain con mayor número de nodos, pero quizás no por mucho tiempo. PundiX tiene como objetivo implementar 100.000 XPOS en todo el mundo que actuarían como nodos de la red de PundiX, eso en tres años.
Consenso x10
Muchas veces llegar a un consenso es un gran problema, como en la vida, cuanto más grande es la población más lento es llegar al consenso. Si un pequeño grupo puede decidir por el grupo mayor en un parlamento, el consenso se puede acelerar, ¿pero de qué manera sabemos que hemos elegido bien al grupo que nos gobierna?
PundiX propone que de sus 100.000 XPOS se elijan aleatoriamente el 1% de los nodos para tomar una decisión, pero señala la necesidad de que los nodos no sean de una misma región, ya que eso haría que el consenso no fuese del todo efectivo. Si cumple con su objetivo de distribuir sus XPOS por todo el mundo conseguirá aumentar la velocidad del consenso a la vez que garantiza su descentralización.
Apertura x10
La Blockchain de Pundi X se está construyendo para que todas las blockchains públicas puedan trabajar en ella. Pretenden que desarrolladores puedan crear dAps que se incluirían en la blockchain de Pundi X, los minoristas de XPOS podrán descargar actualizaciones y expandir su oferta a los consumidores, o incluso se podrán desarrollar Smart contracts que permitan una conexión total entre usuarios de Pundi X y emisarios.
F(dApps)
Los desarrolladores especializados en Android podrán desarrollar aplicaciones en f (x) y por ende en el XPOS, de la misma manera que lo hacen con las apps para Android. Habrá una DApp store que permitirá cargar aplicaciones desarrolladas para el XPOS e instalarla en el dispositivo del comerciante, como si de un Smartphone se tratara. El XPOS además servirá de nodo neutral para que otras blockchains puedan desplegar aplicaciones propias.
¿Qué es el XPOS?
El XPOS es la joya de la corona de Pundi X, sin duda es la pieza con la que pretenden revolucionar la revolución que supone para el mundo la tecnología Blockchain. Este aparato, que recuerda por su forma a un datafono permite que la interacción con las criptomonedas sea algo sencillo para el usuario ya que podrá pagar con tarjeta de crédito, con XPASS, con Apps para adquirir criptomonedas o incluso usar estas últimas para intercambiarlas por bienes y servicios.
La implementación de este dispositivo no es meramente comercial, ya que cada uno representará un nodo en la futura blockchain de Pundi X, por lo tanto, son una pieza clave para el éxito de este ambicioso proyecto.
El Pundi X XPOS soporta pagos desde monederos de criptomonedas o de métodos tradicionales como pueden ser Visa, ApplePay etc… De esa manera el comerciante puede tener en un sólo dispositivo todos los métodos de pago que acepte en su tienda. El comerciante también puede recibir beneficios de los anuncios que se pongan en la pantalla del XPOS, estos anuncios se pagarán con NPXS.De una manera sencilla el XPOS ayuda a los comerciantes a facilitar las operaciones de compra venta de Bitcoin, ETH, XEM, QTUM, ACT, NEM, VERGE, BNB y muchos más, ya que incluso se permite el listado de monedas locales siempre que tengan al menos 5.000 usuarios.
Además de esto, el XPOS permite comprobar las transacciones con criptomonedas, las membresías Premium de la tienda, controlar el inventario, controlar los pedidos etc…
Cuando el empleado va a hacer una transacción, como por ejemplo comprar Bitcoin, el usuario ve en la pantalla el precio en moneda local, entonces escanean el código QR con sus monederos y completan la transacción de manera inmediata.Una vez hecha la transacción de manera satisfactoria, el XPOS imprime un recibo para el cliente y el comerciante, como los datafonos tradicionales. En este recibo también se podrían emplazar anuncios, por los que el comerciante recibiría también una comisión.
Hay que destacar que los puntos de ventas convencionales suelen cubrir una gama de funcionalidades, como puede ser una caja registradora, un datafono de tarjetas de crédito o un software para gestionar el inventario. El XPOS de PundiX es capaz de hacer todo eso y aceptar y procesar criptomonedas, de esa manera enriquece la experiencia minorista tanto para comerciantes como para clientes.

Especificaciones técnicas
El XPOS combina lectores de tarjetas múltiples, estándares de encriptación y funciones de casa de cambio de criptomonedas. Todo ello lo consigue además con un dispositivo ligero que se adapta fácilmente a la mano del usuario.
El XPOS tiene una pantalla de 5,5” de alta resolución y un teclado táctil, con la batería puesta el dispositivo pesa 450g, con unas medidas de 210 x 75 61 mm, consiguiendo reducir muy notoriamente el espacio que ocupan los cajeros de bitcoin habituales, facilitando así su distribución en cualquier tipo de proyecto.
Batería: el dispositivo XPOS es alimentado por una batería desmontablede polímero de iones de litio con una capacidad de 4000mAh (salida de 3.8V), equipada con un cable de carga microUSB y una fuente de alimentación externa, así como una batería de celda de botón de respaldo. La batería y el estado de carga están convenientemente indicados por luces LED.
El software que usa el XPOS de Pundi X está basado en Androidañadiendo una capa extra de seguridad, diseñada para admitir tanto apps sobre blockchain como para admitir monederos de criptomonedas o realizar conexiones continuas con casas de cambio seguras.
El hardware del dispositivo incluye un procesador ARM COrtex MTK8735 de cuatro núcleos (1,3GHz), 1 Gb de RAM, ROM 8G y un módulo dedicado de CPU de seguridad, (Megahunt Micro 1901C). El XPOS viene con una variante de ROM2Gb (RAM) + 16Gb. La capacidad de almacenamiento del dispositivo es de 4,11GB
Lectores de tarjeta, bandas magnéticas y lectores Contact-Less
Pundi X ofrece una gran variedad de hardware compatible que incluye un lector de bandas magnéticas, lectores IC de contacto y sin contacto, lector PSAM, Lector SIM/UID y un lector TF.
Además de esos lectores está equipado con una cámara trasera AF de 5MP con flash que permite escanear códigos de barras o QR, tomar fotos para el registro KYC al activar la tarjeta criptográfica, una impresora térmica para imprimir los recibos, puertos de E/S y micrófono y altavoz integrados.
Gestión segura de claves y protocolos de encriptación
La compatibilidad del XPOS es global, se puede usar por todo el globo terráqueo. Las bandas anchas que pueden usarse incluyen FDD-LTE (B1 \ B2 \ B3 \ B5 \ B7 \ B8 \ B20 \ B28), b (B40 \ B41), WCDMA (B1 \ B2 \ B5 \ B8) y GSM (cuadrante banda). También viene con Wi-Fi de doble banda, Bluetooth y GPS incorporado.
La CPU y su área circundante se diseñaron minuciosamente y se han ubicado en un segmento protegido. Cualquier intento de abrir el componente protegido activará la alerta de seguridad y eliminará los datos confidenciales.
El XPOS tiene un diseño de CPU especial para almacenar la clave pública encriptada y proporciona la seguridad física. Tanto el número de identificación único de la CPU como una clave cifrada generada al azar protegen los datos FLASH y la clave pública encriptada, asegurando que los datos subyacentes de XPOS y BOOT, KERNEL sean seguros.
Desde los niveles BOOT, KERNEL, SYSTEM y APK, la verificación de la firma se realiza capa por capa. Solo APK legítimos se pueden instalar en el sistema. Para actualizar la capa subyacente hasta la capa superior, el sistema debe verificar y validar la firma, de lo contrario, las aplicaciones no se pueden instalar en el XPOS.
El lector de banda magnética está diseñado para evitar la extracción o colocación de detectores. Si se detecta dicha acción, activará una alerta de seguridad y eliminará los datos confidenciales.
Precio y distribución del dispositivo
El precio del dispositivo ronda los 300$ si se compran franjas de 1 a 10 dispositivos, en caso de pedidos mayores va descendiendo su precio. El pago de los 300$ se debe hacer en NPXS, tomando el valor del momento de la compra, parte de esos fondos son la garantía de funcionamiento del XPOS ya que es Pundi X siempre la propietaria del dispositivo y la encargada de repararlo o sustituirlo en caso de avería.

Aunque cada dispositivo vendrá con 10 tarjetas, es posible comprar lotes por separado incluso tu como usuario pedir tu propia tarjeta. Una de las características más interesantes es que si un comerciante hace un pedido medio tendrá la posibilidad de personalizar sus tarjetas con su logotipo e incluso el nombre de su cliente.

El plan de distribución de Pundi X es el de conseguir colocar 100.000 dispositivos como mínimo en tres años, viendo la gran demanda de soluciones como la suya, seguramente esa cifra se pueda quedar corta, en Julio del 2018 se inició la distribución de 5.000 dispositivos a los inversores de la ICO y socios estratégicos y en Agosto del 2017 se abrió la posibilidad de realizar un pedido de otros 5.000 dispositivos, en esta ocasión abiertos a todo el mundo.
Comisiones y beneficios para Pundi X y el comerciante
El comerciante que emplea el XPOS obtiene beneficios de diferentes fuentes:
Obtiene un 1% extra sobre el precio como comisión (Se puede configurar desde un 0% a un 3%, aunque Pundi X recomienda usar el 1%)
Puede vender Criptomonedas aplicando de nuevo esa tarifa del 1%
Puede vender las tarjetas XPASS
Puede configurar su inventario, programas de lealtad, anuncios o imprimir recibos inteligentes
Recibir ingresos por publicidad mostrada en sus recibos o dispositivos
Puede aceptar criptomonedas como medio de pago, recibiendo otra vez el 1% de comisión
Por supuesto, será un pionero en tender un puente entre el usuario medio y el criptomundo.
El 100% de los ingreses que genere Pundi X a través de las transacciones en el XPOS se quemarán automáticamente del circulante de NPXS, eso quiere decir que si en una transacción, Pundi X gana 1$ de comisión, se eliminará automáticamente y de forma permanente el equivalente a 1$ en NPXS de ese momento.
El plan de distribución de Pundi X es el de conseguir colocar 100.000 dispositivos como mínimo en tres años.CLIC PARA TUITEAR
Si la operación se ha realizado con tokens de Pundi X, la comisión se retirará automáticamente del circulante, en caso de que la transacción se haya hecho con otra criptomoneda o incluso con FIAT, se realizará una recompra de la comisión que acto seguido se quemará del circulante total. En el caso de que se haga un pago en FIAT incluyendo pagos con tarjetas Visa o Mastercard se quemarán de la misma forma tokens NPXS.
Imagina entonces que un usuario compra un valor de 1.000€ en criptomonedas a un comerciante, y lo hace además usando la tarjeta XPASS. El cargo total que pagará el usuario será de 1.010€, es decir, 1.000€ por el valor de las criptomonedas y 10€ de la comisión del servicio. De estos 10€ se pagan 3,5€ a Pundi X y 6,5€ al comerciante por proporcionar el servicio de XPOS y XPASS.
Si en un mismo caso el usuario no emplea una tarjeta XPASS de Pundi X y emplea una tarjeta de un Partner de Pundi X o del comerciante, la comisión se repartiría en un 65% para el comerciante, un 5% para Pundi X y un 30% para el Partner emisor de la tarjeta.

Conclusión
Cuando estábamos ideando Bitcobie no conocíamos un proyecto como PundiX, si lo hubiésemos hecho, seguramente la primera guía que hubiésemos escrito hubiese sido esta y no la de Bitcoin. No por desmerecer a la reina de las criptomonedas, ni mucho menos. Lo hubiésemos hecho porque PundiX puede convertirse en la pieza clave de la adopción mundial de la tecnología blockchain.
Su solución facilita la vida al usuario y facilita la vida al comerciante, de hecho, la posibilidad de concentrar en el XPOS todo lo que necesita un comercio para funcionar hace que su atractivo se multiplique por 10.
Por no decir que la relación de PundiX con su comunidad es de las más cercanas que hemos podido ver, cosa que se agradece. El equipo muestra una transparencia total y es de los equipos más activos que existen en el panorama cripto.
La noticia de su propia blockchain que a la vez dará servicio a otras blockchain es una muestra más de que PundiX se quiere convertir en una piedra angular para todo el mundo. El convertir los XPOS en nodos es una auténtica jugada maestra que dotará a PundiX de la posibilidad real de mejorar la velocidad de transacciones soportada por un gigante como VISA.
Como en todo en este mundo hay que ser prudentes y ver la blockchain de PundiX en funcionamiento, pero si funciona igual de ligera y eficaz que su XPOS sin duda estamos ante uno de los proyectos más prometedores que se pueden encontrar hoy en día en el criptomundo (Sin contar que es de los pocos que ya tienen un producto en la calle funcionando, no solamente un MVP o una idea).

What a Blockchain Wallet is? What is its purpose?
Find the answer after reading this article.
Public/Private Key
The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver.
Accessing wallets
Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals.
Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets.
Types of Wallets & Storage Methods
The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners.
Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens.
Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples.
Hardware wallets — LedgeTrezoAlternatives
Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers.
Paper Wallets
Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper!
Real World Historical Examples of Different Wallet Types
Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops.
Neon Wallet
The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible.
Real World Example — Poor Practices
MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets.
In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes.
Case Study: Good Practice Binance, the Attempted Hack
During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt.
Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations
As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange.
Hardware Wallets Advantages and Limitations
We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations.
Paper Wallets Advantages and Limitations
Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever.
Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security
Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose.
You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait.
How to Monitor Funds
There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor.
That’s not all! You can learn how to transfer and monitor the funds in and out of your wallet by clicking on the link.
