Dr Peng actively explores blockchain Technology

1. First of all, we can take a look at the official website explanation of blockchain technology. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
as we all know, blockchain technology is an independent underlying architecture from bitcoin system. From the perspective of architecture model, it is a set of distributed ledger, which is naturally used for bookkeeping
in the blockchain technology, if you want to generate accounting records, you need to have the transaction and flow of funds. Therefore, in the initial blockchain technology, the cryptocurrency corresponding to the main network is used as circulation goods, and the circulation transaction records of cryptocurrency between the accounts of the main network of the blockchain will be recorded on the main network
different from other transaction record databases, transaction records on the main network of blockchain technology will be recorded on all block nodes (i.e. all data blocks) in the main network, which is the so-called decentralization principle. That is to say, in blockchain technology, there is no central database to store all records, Every block on the chain has the transaction data of the whole chain, that is to say, every data block is the center
another feature of blockchain technology is that it can't be tampered with, because every transaction on the blockchain will be recorded in all blocks on the chain, so no single data block can change the record. Even if you change it, all other data blocks will also record real data, and each group of data can be traced back to the first time
because of these characteristics of blockchain technology, after the advent of bitcoin, blockchain has also attracted a lot of attention, and many people also began to want to use blockchain technology to make a centerless, traceable and unchangeable data, so as to ensure the credibility of the data
however, blockchain technology also faces many problems, such as single application scenario, non modifiable original error data, non recoverable currency stolen by hackers, etc.

2. Several successful ones are block chain housing rental platform in xiong'an New District, SMIC block chain public service platform in Changsha high tech Zone, and block chain Real Estate Registration Platform in Loudi. Hunan has done a good job in the application of block chain technology in the whole country. There are mature and successful application cases in provincial capitals and prefecture level cities.

3. Blockchain belongs to it technology, and finance is an application direction of blockchain
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

Blockchain and artificial intelligence are the next era

There is a good combination between the two

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

artificial intelligence, abbreviated as AI. It is a new technical science to research and develop the theory, method, technology and application system for simulating, extending and expanding human intelligence

Artificial intelligence is a branch of computer science, which attempts to understand the essence of intelligence and proce a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system. Since the birth of artificial intelligence, its theory and technology have become increasingly mature, and its application fields have also been expanding. It can be imagined that the scientific and technological procts brought by artificial intelligence in the future will be the "container" of human intelligence. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like human and may surpass human intelligence

At present, blockchain technology can be divided into three versions

At present, in the first three versions, there are some problems, such as the lack of decentralization, low scalability, the mismatch between the incentive of the blocker and the best profit of the whole network, and the network always runs at the maximum capacity, such as bitcoin and Ethereum, which affect the efficiency

Velas combines the two to develop a public chain that can learn and improve itself

Velas enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and concts self-learning and self optimized public chain, aiming at improving the security, interoperability and high scalability of transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed

technically, Velas has integrated functions and services such as cross chain payment, multi signature wallet supporting multi currency, anonymous transfer, etc. Its Ecosystem focuses on all application scenarios covering transaction and payment, such as exchanges, multi signature wallets, merchant platforms, etc. after AI is fully connected to the system, the transfer fee can be completely exempted

and complete decentralization through AI enhanced dpos (aidpos) & gt; AI chooses who to mortgage the token according to the needs of blockchain & gt; Velas only blocks when needed & lt; Between every 1 second and every 2 minutes & gt& gt; Scalability (up to 30000 TPS) & gt; Block procers are selected by artificial intuition< br />

For blockchain messages, bitcoin is to blockchain what e-mail is to the Internet. As we all know, e-mail for the first time in the history of human information dissemination and exchange realizes the function of timely, free and verifiable sending data to anyone else in the world. Both the sender and the receiver can save copies of the data sent in e-mail. However, the e-mail data copies retained by both parties also become an inherent defect of online value transfer, because both parties have their own value. Therefore, it is necessary to ensure that the value is not double paid by the existence of third-party institutions, such as banks, stock exchanges, clearing centers or notaries. As an internet protocol, bitcoin can transfer value to each other instantly and safely without the existence of intermediary organizations such as credit granting third party, which reces transaction cost and improves transaction efficiency. Xiaobian now arranges the schematic diagram of blockchain technology and related technical principles for you

literally, blockchain is a distributed account book system composed of a series of data blocks generated by cryptographic methods. Each data block contains a large amount of transaction information, which is used to verify the validity of its information and generate the next block. These blocks are arranged in the order of generation, and each block is a node

the remarkable feature of blockchain is that there is no third-party supervision as a central server, and the transaction information in the block cannot be changed. The information contained in the block can be financial transactions or any other digital transactions, including documents. The success of the Internet business model, which has dominated the business world of human society for a long time, depends on the third-party financial institutions as credit granting institutions to process and mediate electronic transactions. The role of the third-party credit granting institutions is to verify, protect and save transaction records

However, there are still a large number of fraulent online transactions, which need to be mediated by a third party, resulting in higher transaction costs. Bitcoin, based on blockchain technology, uses encryption to prove, rather than credit a third party, so that all parties willing to trade can achieve online transactions through the Internet

every transaction can be protected by digital signature and sent to the "public key" of the receiver who uses the sender's "private key" for digital signature. The owner of bitcoin, namely cryptocurrency, needs to prove the ownership of its "private key" in order to consume and trade online. The receiving party uses the sender's "public key" to verify the digital signature on the transaction, that is, the ownership of the other party's "private key"

each transaction is broadcast to each node in the bitcoin network and recorded in the public ledger after verification. Moreover, before each transaction is recorded in the public ledger, it needs to verify its validity. Therefore, the verification node needs to ensure two things before recording each transaction: that is,

(1) consumers have the signature authentication of their encrypted electronic currency

(2) there are enough encrypted e-money in consumer accounts

Figure 1 shows the transaction process and principle based on blockchain technology

I hope this answer will help you

8. The draft of the "fourteenth five year plan" points out that seven key instries of digital economy, such as instrial Internet, blockchain, artificial intelligence and so on, as well as digital application scenarios such as intelligent transportation and intelligent energy, should be further defined, and "accelerating digital development and building digital China" should be regarded as an independent chapter, from creating new advantages of digital economy to speeding up the construction of digital society, From improving the level of digital government construction to creating a good digital ecology, this paper outlines the new prospect of Digital China Construction in the next five years. In 2025, the added value of core instries of digital economy will account for 10% of GDP
through consensus algorithm, the user data can be updated synchronously among judicial nodes such as notary office, Arbitration Commission, Internet court, judicial identification Institute and right institution on the security chain, so that each node on the security chain can realize real-time exchange of data and information, and effectively improve the judicial credibility of the blockchain data
based on the mode of "blockchain + judicature + application", e-security deeply arranges e-signing, and helps enterprises transfer traditional offline paper contracts to online signing by means of professional underlying data storage capability, full evidence chain technology and post signing judicial services, providing real name authentication, E-contract, signature management and other services
, the use of blockchain technology for the original works of online right confirmation, infringement detection and infringement forensics, as well as online right registration and other intellectual property protection services. It provides online arbitration filing application, agent execution, direct evidence to arbitration commission and other services for enterprises and indivial users. At the same time, it can also provide the notary office with the construction of Internet notary system, notary intelligent terminal and corresponding customized services, and help the notary office to comprehensively transform and upgrade its business. At present, it has successfully provided judicial services such as Internet notarization system construction for many notary offices. And other application scenarios, lead the blockchain to different instries and fields, provide full supporting solutions, and accelerate the rapid implementation of blockchain in the whole instry. As the cornerstone of digital economy, blockchain technology plays an important role. Through "blockchain +" to quickly complete the transformation and upgrading, release new momentum for the development of digital economy.
