Blockchain AI technology public chain

1.

blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

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. In essence, it is 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 bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

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

In recent years, blockchain and artificial intelligence have been very popular

first of all, blockchain is to establish a decentralized network. The so-called decentralization means that the network does not belong to you or me

it belongs to everyone

Artificial intelligence is a new technology science that researches and develops the theory, method, technology and application system for simulating, extending and expanding human intelligence. In other words, "machine self-learning"

in this way, we can think about the combination of blockchain and artificial intelligence

first of all, we need to understand that blockchain can be divided into three stages

However, in the first three stages, there are some problems, such as the lack of decentralization, low scalability, the mismatching between the incentive of the blocker and the best profit of the whole network, and the network always running at the maximum capacity. Serious waste of resources and rece efficiency

so can we combine artificial intelligence with underlying public chain technology to solve these problems

The answer is yes! And there has been team research and development, and has made a certain progress

Velas is a public chain that enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and carries out self-learning and self optimization. It is committed to improving the security, interoperability and high scalability of the transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed. Not only that, AI chooses who to mortgage the token according to the needs of the blockchain; Velas only blocks when needed; Every 1 second to every 2 minutes; Scalability (up to 30000 TPS); Block procers are selected by artificial intuition

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 />
