P2P blockchain source code

1. In recent years, blockchain digital assets represented by bitcoin have become popular all over the world. Financial institutions, technology companies, investment companies and other participants at home and abroad have invested a lot of human, material and technical resources in the research, development, design, testing and promotion of blockchain digital assets. In order to realize the main characteristics of "four can and three can't" of blockchain digital assets, we can build the core technology system of digital assets by relying on 11 technologies of security technology, transaction technology and trusted guarantee technology. First of all, security technology is used to ensure the fluidity, storability, controllable anonymity, unforgeability, non repeatable transaction and non repudiation of blockchain digital assets. digital currency security technology mainly includes basic security technology, data security technology and transaction security technology. Basic security technology includes encryption and decryption technology and security chip technology. Encryption and decryption technology is mainly used in currency generation, secret transmission, identity verification and other aspects of digital assets. The establishment of a perfect encryption and decryption algorithm system is the core and foundation of the digital assets system, which needs to be customized and designed by the national password management organization. Security chip technology is mainly divided into terminal security mole technology and smart card chip technology. Digital assets can be traded in the form of mobile terminal based on terminal security mole. As the carrier of secure storage and encryption and decryption operation, terminal security mole can provide effective basic security protection for digital assets. Digital asset system trading platform blockchain technology research and development of data security technology, including data security transmission technology and secure storage technology. Data security transmission technology transmits digital asset information through ciphertext + MAC / ciphertext + hash to ensure the confidentiality, security and non tamperability of data information; Data security storage technology stores digital currency information by means of encryption storage, access control, security monitoring, etc., to ensure the integrity, confidentiality and controllability of data information
transaction security technology includes anonymous technology, identity authentication technology, anti plicate transaction technology and anti-counterfeiting technology. Anonymity technology realizes controllable anonymity of digital assets through blind signature (including blind parameter signature, weak blind signature, strong blind signature, etc.) and zero knowledge proof; The identity authentication technology verifies the user's identity through the authentication center to ensure the validity of the digital asset trader's identity; The anti plicate transaction technology ensures that digital assets are not reused by means of digital signature, serial number and time stamp; Anti counterfeiting technology ensures the authenticity of digital assets and transactions by means of encryption and decryption, digital signature and identity authentication. Secondly, the online transaction and offline transaction of digital assets are realized by transaction technology. Digital asset trading technology mainly includes online trading technology and offline trading technology. As a legal currency, digital assets should not be rejected by any unit or indivial, and can be traded online or offline. Online transaction technology realizes online transaction of digital assets through online device interaction technology, online data transmission technology and online transaction processing; The off-line transaction technology realizes the off-line transaction of digital assets through the off-line device interaction technology, off-line data transmission technology and off-line transaction processing technology. Finally, trusted guarantee technology is used to provide a safe and reliable application environment for the issuance, circulation and transaction of digital assets in blockchain. Digital asset trustworthiness assurance technology mainly refers to trusted service management technology. Based on trusted service management platform (TSM), it ensures the security and trustworthiness of digital asset security mole and application data, and provides security chip (SE) and application life cycle management function for digital asset participants. Trusted service management technology can provide application registration, application download, security authentication, authentication management, security evaluation, trusted loading and other services for digital assets, which can effectively ensure the security and credibility of digital assets system
what is blockchain? Blockchain technology, also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, so that everyone can participate in database records. Blockchain technology development blockchain technology development what is a blockchain system? Blockchain system is a database system with integrity. The data written into the system will be automatically copied to the nodes of the blockchain, which can achieve transactional data preservation, support the management and development of databases in various instries, and be proced in combination with various needs. 294.497 billion US dollars, or 2.60%. This week, five new projects entered the top 100, namely FST, ZB, Wix, wax and MXM. On August 11, the price of bitcoin was $11523.58, up 3.20% from last week, and Ethereum was $216.09, down 3.86% from last week. The 24-hour turnover of this week increased by 2.63% over the same period last week; Among the top 100 projects, the total market value and average market value of currency projects increased significantly, and the classification composition of global blockchain assets top 100 projects was stable.

Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:

1, open source code

upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public

2, complete decentralization

anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"

3. Developing decentralized applications

through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers

The current blockchain procts can be defined as Ponzi scheme except bitcoin. The concept of blockchain was born in 2008, but it was after the growing market value of bitcoin that it was recognized by the public and became popular in China. Bitcoin gained its market value only eight years ago after a foreign programmer spent 10000 bitcoins to buy two pizzas. After eight years of long value-added period, the 10000 bitcoins, which once had a market value of only $40, now have a peak value of nearly $200 million

technology is a liar without capital, and the platform built by blockchain without transaction record is a great liar

blockchain builds a fair trust platform with the method of [all bookkeeping] (generally speaking, I called XXX to borrow my 100, and everyone wrote it down, so the transaction can be completed without middleman, and the completion process depends on the records of the whole platform), but the transaction currency does not generate value out of thin air, but accumulates its value little by little in each transaction, In the end, it became money. The endorsement of its value is caused by countless transactions

then other blockchains have three major problems: 1. The maturity of Technology (there is no recognized algorithm now) 2. How can you guarantee the appreciation of these currencies? 3. How to ensure that others don't yell for transactions? The method of blockchain is to increase the difficulty of yelling out (for example, if no one gives me money, I also yell for money, and you can write it down in a small notebook). The method of blockchain is to remember that a small notebook needs to be upside down and write with a pen in its mouth...), so the problem of mining out of thin air may be caused by the technologist

therefore, blockchain is basically a Ponzi scheme except for accumulating a lot of bitcoin in the transaction process. What you're involved in is that the platform will use their virtual currency to trade a lot in the future , whether the monetary value of blockchain output is high or not is e to its trading volume as an intermediate currency, is no different from stock speculation - but stock speculation is actually a Ponzi scheme

the funniest thing is, Blockchain has been calling for decentralization, but if you want to make money to make the circle, the more you have to rely on the endorsement of the big platform to ensure the circulation of money, the more you want to be decentralized, the more you need to help the central GZ government legislate - the funniest thing in life is this, just like VR was riding on pockmango, an AR proct in the first year

6. Bitcoin P2P technology is a virtual encrypted digital currency. That's right. It's more essential. The term blockchain came into being after the birth of bitcoin, because bitcoin opened the door to the blockchain field. The popularity of bitcoin has attracted more and more people's attention to blockchain technology. Before the birth of blockchain, many veteran people used to call it P2P, which is probably the case. Many of the world's leading exchanges, such as okex, have developed some functions based on blockchain technology. You can learn more about okex platform.

7. Blockchain technology can effectively solve the current dilemma of bill market and P2P field (deep data mining and application, data security), provide reliable technical support for effective supervision and low-cost supervision, and build a new trading platform for bill market innovation. In terms of system development scheme, there are not many enterprises that can apply blockchain technology to build. The specific scheme that can be found at present is also developed by Yingtang Zhongchuang. The P2P system scheme developed by Yingtang Zhongchuang with blockchain technology can solve some problems encountered in big data credit investigation.
