300099 blockchain technology explanation

1. 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.

2. Bitcoin mining machine for bitcoin mining equipment mining equipment ordinary computer USB mining machine professional ASIC mining machine

using ordinary computer CPU does carry out bitcoin mining. Because bitcoin mining has formed a huge instry all over the world, ordinary computer is difficult to dig bitcoin. You need to buy expensive and professional bitcoin ASIC mining machine and join bitcoin miners' organization to dig bitcoin, that is, join the mine to dig Mining

bitcoin mining machine market has a high threshold. It is suggested that new players who want to dig for gold should be cautious.

at present, bitcoin mining needs professional ASIC mining machine. For example, Avalon mining machine, the mainstream of the market, is said that Avalon's fourth generation 28nm process chip, that is, chip flow, is expected to focus on the fifth generation 16nm process chip

3. So far, it seems that Guo Jia hasn't said that any digital currency is illegal. It's just that the value is high or low. For example, the British Saipan coin has noble blood, and the famous bitcoin has not made many billionaires

4. Blockchain technology involves a wide range of disciplines and contents, including network communication, data storage, data encryption, consensus mechanism, security mechanism, cryptography and other related contents. Only by comprehensively mastering these knowledge can we better master the blockchain technology. In addition, the most important thing for learning blockchain technology is to use blockchain in practice, and the real purpose of learning technology is to develop applications that are helpful to life and proction. Xuanling technology has been committed to the development of blockchain technology related applications, and has an experienced development team. If you have relevant intention, you can contact the official website.

1. Technical language

Python and go are two technical languages mentioned by many companies. Learning needs to be a priority. Moreover, these two languages have great application in the technical direction outside the blockchain. For example, go is used in the background construction of large concurrent systems, and Python is used in the construction of artificial intelligence systems. So learning these two languages is a priority

2. Technical framework

master one or more of bitcoin, Eth and hyperledger. Needless to say, BTC is written in C + +. A large number of currency projects, such as lightcoin, dash, Monroe, zcash, use bitcoin technology for secondary development

eth is the representative of blockchain 2.0, which can build a variety of application classes DAPP on eth network. Now a large number of application blockchain projects are developed using eth platform

hyperledger fabric is a blockchain development platform pushed by IBM, which is mainly used for the development of alliance chain, and is the most popular alliance chain development platform at present

3, algorithm

pow (proof of work), POS (proof of rights and interests algorithm), pbft (Byzantine fault-tolerant algorithm) are all important components of cryptography in blockchain. A full understanding of these algorithms will help you to have a better understanding of cryptography when you participate in the underlying development of blockchain projects

extended data:

blockchain technology is a kind of Distributed Accounting Technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in the establishment of the database, and each established data can not be tampered with, and everyone participates, The problem of trust between strangers is solved

blockchain technology has emerged. It is an accounting technology with the participation of the whole people. The transaction information and data between AB and ab are published to the public and can not be tampered with. As we all know, there is no need for any authoritative Third Party C here. In other words, everyone in the system plays the role of C, which is also called decentralization
