1.
bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below
The inventor of 
bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system In 2010, he graally faded out and handed over the project to other members of the bitcoin communityNakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is
bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin
2. How to operate the isolation witness? In fact, it's not so simple ~
isolation witness is a method of blockchain expansion, which has been successfully implemented on lightcoin and bitcoin
at present, each block in the blockchain not only records the specific information of each transfer transaction, that is, at which time point the account receives or transfers out how many bitcoins, but also contains the digital signature of each transaction, which is used to verify the legitimacy of the transaction. The miner needs to verify each transaction one by one with digital signature when packing the block. After confirming that there is no problem, the transaction will be recorded in the block
however, for ordinary users, they only care about the number of assets in each account, and do not need to verify each transaction one by one. Isolation witness is to take out the digital signature information in the block, so that each block can carry more transactions, so as to achieve the purpose of expansion.

3. Bitcoin isolation verification simply means that there is an additional side chain. The main chain and the side chain complement and support each other. Isolation verification is to solve the problem of bitcoin congestion. At the end of 2013, the problem of bitcoin congestion has appeared, and the expansion has become the consensus of the community, but there is no consensus on how to expand
in 2016, the community held a meeting in Hong Kong on capacity expansion. At the meeting, China's absenteeism and bitcoin core reached a consensus and proposed a compromise scheme, namely hard fork and isolation certification. This is the result of compromise between the two sides, but later the core went back on its words and forced absenteeism to accept the isolation scheme, but did not expand the capacity. China mostly opposes the exclusion of isolation verification.

4. Among the top ten digital currencies listed by the Wall Street organization fundstrat, BCH ranks first. Therefore, BCH has more investment value, flexibility and innovation
it is reported that Microsoft has accepted bitcoin cash deposit and zero confirmation instant payment, and there is no transfer fee for bitcoin cash recharge, which is different from the 1.2% transfer fee for bitcoin recharge. Another interesting phenomenon is that Microsoft has put BTC and BCH payment options on the "bitcoin" option on its website. Companies such as tor browser, overstock.com and eff also gave the same answer. The outside world holds a neutral attitude towards who is the real bitcoin. Let users choose for themselves and they will give the right answer
"a hundred legged insects, die but not stiff" is the most appropriate word to use in bitcoin. Bitcoin has been preconceived and has great influence in the society. In the short term, it is a mountain that is difficult to surpass. However, users will give the best choice according to their experience. As time goes on, BCH has low service charge, low cost and low cost The advantages of convenient payment will graally be recognized. At that time, Nokia used to be the dominant mobile market. At the peak of 2010, its market share was as high as 35%. When it was prosperous, it would decline. Because of its complacency, Nokia lost touch with the smartphone market and was acquired by Microsoft only three years later. It will take time to see whether bitcoin will follow Nokia's footsteps, but whether bitcoin cash can become a rising star is self-evident.

5. Friends who are new to the currency circle are dazzled to see all kinds of digital currencies. What are the origins and characteristics of these cryptocurrencies? Here is a brief introction to some mainstream cryptocurrencies< Bitcoin is the earliest cryptocurrency. In 2008, an Internet geek named Nakamoto Tsung published a paper called bitcoin: a peer-to-peer e-cash system. In 2009, the first creation block was g up by Nakamoto Tsung and has been developing ever since. The original block size of bitcoin was only 1m, and the congestion problem was getting more and more serious. As a result, the block expansion was put on the agenda. The core development group advocated the use of isolation witness and lightning network to realize the expansion, while the big block group advocated the direct expansion of the block. At last, on August 1, 2017, bitcoin cash (BCH) forked from bitcoin (BTC) and expanded its capacity by expanding the block. After this split, bitgold, bitdiamond, super bitcoin, bitgod and many other split coins have sprung up. Later, BCH itself encountered a bifurcation. The Australian CSW, who calls himself Nakamoto Tsung, has to continue to expand the block and lock the underlying protocol of bitcoin. He claims to make a bitcoin that meets Nakamoto Tsung's vision. This time, the bifurcation coin is called BSV
apart from BCH and BSV, most of the other bifurcated currencies have declined. BTC, BCH and BSV represent the exploration of three different directions respectively. BTC is the most conservative and cautious, BSV is the most radical, and BCH is relatively mild and graal. At present, BTC enjoys the name of bitcoin in fact and has the largest market value< br />
< At the end of 2013, vitalik buterin (V God), a gifted programmer born in 1994, published a white paper on Ethereum, proposing the idea of adding various smart contracts to cryptocurrency, which can be used in social networking, trading, games and other fields. The market value of Ethereum has soared all the way, and it will soon be second only to bitcoin, Ethereum with smart contracts is also known as blockchain 2.0
in 2016, Ethereum encountered a serious hacker coin theft incident (DAO), and God V decided to delete the coin theft record by using rollback method. However, some people who insisted that the blockchain should not be tampered with opposed rollback, so Ethereum also split. Unlike bitcoin, the original Ethereum chain has become a minority, known as the Ethereum classic (etc), and the new chain that has been rolled back has become a majority, the de facto Ethereum (ETH)
stable currency system
stable currency is generally anchored legal currency, which can be used to exchange legal currency 1:1 to the issuer. The currency value is relatively stable, but sometimes there will be a small amount of premium in transactions, which is widely used in cryptocurrency transactions. Now the most common stable currency is the usdt issued by tether company, 1 usdt = 1 dollar. Stable currency is generally issued on other cryptocurrency networks, such as bitcoin Omni protocol, Ethereum erc20 protocol, etc< br />
in anonymous currency
on bitcoin, every transaction is clear and searchable, although we don't know who the person behind the address is. Some people think that the privacy of bitcoin is not enough, so some anonymous coins, such as XmR, dash and zcash, which can cover up user information, have emerged. Monroe coin uses ring signature technology, dasey coin adopts mixed coin technology, and big zero coin uses zero knowledge proof, which can play an anonymous effect in different degrees
platform currency system
some digital currency trading platforms often release their own platform currency, and there are certain discounts for trading with platform currency, such as okb of okex, HT of fire currency, BNB of coin security, etc<
some other mainstream currencies
lightcoin (LTC) has copied the code of bitcoin, replaced the consensus algorithm, and shortened the block out time. When bitcoin wants to upgrade, it often does experiments on bitcoin first. Lightcoin is known as "bitcoin, lightsilver"
XRP is currently the third largest currency in market value. It is an Internet transaction protocol, allowing users to transfer money around the world quickly and cheaply
grapefruit coin (EOS), known as blockchain 3.0 and Ethereum upgrade, attempts to introce more functions and application expansion on it

"bitkangaroo" is the first digital currency financial service platform in the world that allocates theoretical revenue from its own mines and machines without power failure. The platform is mainly based on cloud computing procts, and the theoretical revenue is allocated by "1tash" of Wanyou computing power's professional mine, a strategic partner, on a regular basis every day, integrating high-yield, security, liquidity, transparency and professionalism
High Yield: the platform aims at "increasing users' assets", and customers can choose a variety of derivatives to prevent systemic risks
Security: the team stores the standby digital assets in the cold multi signature wallet, and in case of any accident, the reserve fund will be used to distribute revenue to customers
Liquidity: the platform allocates income every day, and can withdraw as soon as it reaches the minimum currency withdrawal standard
transparency: mine data and mine logs are open and transparent, and users can monitor the actual computing power of the mine at any time through the data center monitoring system
Professional: the mine is operated and managed by professional personnel who have been engaged in deep mining for many years. Each unit is isolated by professional network interruption to prevent virus invasion. Multiple standby networks are used in the computer room to eliminate non systematic risks in an all-round way

XTT (Xin time token), based on Ethereum erc20 platform, is a decentralized digital currency carrier based on blockchain as payment technology
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized Ethernet virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)
the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014
extended data:
background
bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years
the blockchain of bitcoin is actually a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network
however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions
In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoinreference source: network Ethereum

9. Bitcoin client (wallet): software for sending and receiving bitcoin. The most popular is the client downloaded from bitcoin's official website. There are other options
Wallet: it has two meanings: 1. It refers to bitcoin client (client generally refers to desktop client; 2; Wallet generally refers to lightweight client or online wallet); 2. A file that stores bitcoin addresses and private keys
bitcoin address: a string such as "" that you can get from the receiver. Create an address with the client and generate the corresponding private key at the same time
private key: in the context of bitcoin, the private key is associated with the corresponding address (technically, the address is the hash value of the public key corresponding to the private key), and is stored in the bottom layer, allowing you to transfer the bitcoin owned by the current address. Please note that because of the ECDSA encryption algorithm used by bitcoin, it can generate the corresponding public key and address from the private key
transaction: a transaction is a message that informs the whole bitcoin network of the occurrence of a transaction, allows the receiver to use the money, and prevents the sender from double paying.

10. Isolated witness (usually abbreviated as segwit) is an update of bitcoin software, which aims to solve a series of serious problems faced by bitcoin
segwit is a proposed update to bitcoin core developed by bitcoin's long term team. Bitcoin core is the most popular bitcoin standard client, which is used by most enterprises in the instry.
