1. 1. What is the technology of blockchain?
2. They are both encrypted virtual digital currencies. The difference is that bitcoin was born early, has a large audience, and is highly accepted (Dell and Microsoft both accept bitcoin payment). Bitcoin is the representative and originator of cryptocurrency, and has a high market value. Bitcoin is also a small-scale social experience. Ethereum is the second generation of digital currency, and IOT is the follow-up currency, It is also developed based on the smart contract of Ethereum. Last time I saw their founder Zhang Feng's roadshow, it was good
3. Blockchain in English is blockchain. Block literally means block and block, while chain means chain and chain
1. The use of cryptography technology, encryption and decryption, so that records can not be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc
2. The huge amount of computation needs to be supported by a reasonable reward mechanism. Because every transaction has to be recorded, so far, bitcoin's blockchain has more than 60 g's. Each new transaction needs to confirm all the information related to the transaction account to make sure that the transaction is effective. The huge amount of calculation needs powerful computer to complete
in order to encourage powerful computing power to participate, bitcoin gives two kinds of rewards: one is to issue a certain amount of bitcoin to these computers every day; the other is to issue a certain amount of bitcoin to these computers every day; Instead, all transfer fees will be awarded to these computers The technical term of these computers is "miner", and the person who owns the miner is called "miner"
coin China has made efforts in asset digitization and launched a digital currency crowdfunding platform, coin China.

4. Blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.
