BTC bitcoin
bitcoin is the first distributed digital asset platform created. Since its launch in 2009, it has proven to be not only the most popular, but also the largest market capital value. In addition, it is also the most expensive, with a value of $10710 per coin on February 17, 2018. Bitcoin introces the first blockchain distributed ledger dedicated to recording all transactions, and gets rid of the function that users need a central authority to process or verify transactions
its goal is to provide a platform for users to conct cross-border transactions without any intermediary, which is what we call decentralization. The platform's largest money (BTC) supply is about 21 million. Of this figure, about 16.5 million have been mined and are now in circulation. It is mined all the time around the world to ensure the circulation of coins
Advantages:1. Its distributed system provides users with great freedom
2. High portability

2. The user may lose the key
eth Ethereum
Ethereum is also a distributed platform, which was created by Network Programmer vitalik buterin in July 2015. Ethereum aims to enable users to create and deploy smart contracts. One of the main functions of smart contracts is to allow the creation of encrypted assets or tokens running on Ethereum networks. Ethereum token is used to purchase various functions such as cloud storage space. These tokens are stored in a digital wallet compatible with Ethereum blockchain
Ethereum's digital currency ether serves as the medium for executing smart contracts. At present, about 98 million ether coins have been mined and circulated, and the circulation supply increases by about 18 million every year. Ethernet coin is created to run on the Ethereum network. It can be used to compensate the participant nodes or transfer from one user to another

< H2 > extended data:generation principle:
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique
in the metaphor of banknotes, bitcoin is the number of the top word of a banknote. The number of the top word on a banknote owns the banknote. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
after completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to post the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
BTC, usdt, ETH, BCH, LTC mean respectively:
1, BTC
bitcoin. The concept was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software is designed and released, and the P2P network is built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
2, usdt
TEDA currency is a virtual currency that links cryptocurrency with legal currency US dollar, and is a virtual currency kept in foreign exchange reserve account and supported by legal currency
EthEthereum is an open source public blockchain platform with intelligent contract function, which provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether
4. BCH
bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers
at 20:20 on August 1, 2017, bitcoin cash starts mining, and each bitcoin investor's account will have the same amount of bitcoin cash (BCH)
5, LTC
litecoin, abbreviated as LTC, currency symbol: & # 321;; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")
The token on theblockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum
the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin
extended data:
Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks
for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound
in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum. The concept of Ethereum was first inspired by bitcoin by vitalik buterin, a programmer, between 2013 and 2014, and now it's 2.0. Ethereum 2.0 is also something that the whole coin circle is waiting for. In order to celebrate the birth of the genesis block of eth2.0 on December 1, chinacoin officially supports the exchange of eth2.0 verification nodes at 17:00 Hong Kong time on November 20, 2020. It will invest its own eth in the verification node mining and exchange qeth to obtain liquidity. It will participate in the mining as soon as the exchange is received. Now it will give back to the user's welfare. The top 1000 eth enjoy the over exchange of qeth according to the ratio of 1:1.02. Compared with eth2.0, qeth has too many advantages: liquidity is guaranteed, users do not need to bear the technical cost, the threshold of participation does not need 32 eth, as low as 0.1eth, nodes are maintained by the platform, and the revenue is distributed according to eth2.0< br /> < br /> < br />
with Ethereum officially confirming erc-721 as one of the new token standards, many people are asking what erc-721 is recently. There are many technical posts on the Internet to analyze the code differences between erc-721 and erc-20. They are very unfriendly to Xiao and leek. With the attitude of sharing knowledge, I will try to explain the most significant differences between erc-721 and erc-20 with intuitive words
erc-20 standard token:
1
2. It can be subdivided into N parts (n = 10 ^ 18)
conclusion: similar to the currency in real life, it can perform all monetary functions. The application cases are similar to legal currency and virtual currency
erc-721 standard token:
1
2. The minimum unit is 1 and cannot be subdivided
summary: non homogeneity exists widely in life, such as art, pets, handicrafts, custom-made items, etc., and can even be used to mark students in schools, doctors and patients in hospitals, etc. The application scenarios are very wide
the above description is relatively concise. Taking a look at specific projects can help you better understand erc-721 standard. At present, the popular projects using erc-721 standard can take a look at
- cryptokitties (cryptokitties | collect and breed digital cats!)
this is the "ethereal cat" mentioned before. It's very basic and interesting. Each cat is a token with unique attributes. The more unique the attributes, the higher the value of the cat. It's very popular, but its development potential is limited
- 0xcert (0xcert - supporting uniformity.)
this project is a recent project of personal interest, which is close to life and easy to implement. Erc-721 token is used to mark real-life artwork or a unique item, and record the basic attributes, characteristics, value, previous owners, etc. It is very helpful in combating counterfeits and piracy. It may also be used in the second-hand market, exchange of valuables and other scenarios in the future
personally, I am very optimistic about erc-721 standard. After the whole blockchain instry calms down from the carnival, the implementation of the project has become the first consideration for developers, and erc-721 is very suitable for connecting the blockchain with the real world.
bitcoin, Ruitai coin, Laite coin, Ethereum and other digital cryptocurrencies all use blockchain technology
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is used to verify the validity of its information (anti-counterfeiting) and generate the next block. Blockchain is a series of data blocks generated by cryptography, each of which contains the information of a bitcoin network transaction
