1 Overview
"Blockchain and Artificial Intelligence: Building an Intelligent Digital Economy World", published by People's Posts and Telecommunications Publishing House, edited by Liu Quan. After looking at it, I feel that the specific applications are very general and very shallow, with little benefit. The author is a Ph.D., the director of the Cyber Security Institute of CCID Think Tank of the Ministry of Industry and Information Technology, the president of CCID Blockchain Research Institute, and the secretary general of China Electronic Certification Service Industry Alliance. Generally speaking, I have also seen some CCID think tanks before. Basically, these government-run think tanks have less knowledge than the industry. They can be used to look at them in general, but they will fall into the pit if they really matter.

2. Blockchain technology
2.1 Blockchain related concepts and core technologies
2.1.1 Concept
Consensus mechanism:
Timestamp:
Smart contract:
Public chain, alliance chain, private chain:
Side chain, cross chain, lightning network:
The side chain is based on the transfer of the main chain.
Cross-chain is to solve the interoperability between blockchains and is the key to realizing the Internet of Value.
The Lightning Network provides technical solutions for off-chain transactions in the “encrypted digital currency” frequent small-value transaction scenarios that suggest delays and other issues. It includes two core mechanisms: multi-signature address, sequence expiration revocable contract (RSMC) and hash time locked contract (HTLC). The off-chain payment channel functions as a third-party platform similar to Alipay.
2.1.2 Core Technology
Consensus algorithm: The consensus mechanism is used to solve the process of each node in the blockchain reaching a consensus on a proposal or record. The point-to-point network has a large delay. Paxos, Raft, PBFT, PoX and other algorithms. The public chain scenario is mainly PoX, such as Proof of Work (PoW), Proof of Stake (PoS), Algorithm and Proof of Stake (DPoS). Consensus algorithms for alliance chain scenarios are mainly Byzantine fault-tolerant algorithms PBFT and RAFT.
Asymmetric encryption algorithms: RSA, ECC, D-H, etc. ,
Distributed storage technology
P2P network technology:
2.1.3 Features
Decentralized
Technology-based trust
Data is difficult to tamper with and traceable
High reliability of system and data
High scalability and inclusiveness
2.1.4 Application value
Widespread application will realize the reconstruction of business organization and the transformation of social collaboration methods:
Disintermediation
Data confirmation.
Blockchain can perfectly solve the problems of key data protection and authorized access: data ownership confirmation and management, hard-to-tamper timestamps can solve data tracking and information anti-counterfeiting problems, and necessary privacy protection mechanisms.
Flexible programmable features (smart contracts) help standardize the existing market order
3 Blockchain + artificial intelligence integration promotes the development of digital economy
3.1 Features of the Digital Economy
Self-organization, marginal cost tends to zero, co-governance and sharing, clear data property rights, and network effects.
3.2 Blockchain + artificial intelligence integration
Data becomes the means of production of the digital economy. Artificial intelligence improves productivity, and blockchain changes production relations.
The Internet solves the problem of information dissemination, and the blockchain solves the problem of trust and realizes the transfer of value. The combination of the two realizes the value transmission Internet and realizes the digital economic ecology.
3.3 Fields of integrated development of blockchain + artificial intelligence:
(1) Fields requiring high-quality information sharing
(2) Fields that need to meet data security and confidentiality
(3) Areas that require supervision and achieve information transparency
(4) Fields that need to be traced and confirmed
(5) Areas where trust and multi-party collaboration are needed
