Matching engine blockchain

1.

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare

First, in the field of finance,

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

2. Can search on the Internet, ah, this intervention program code

3. Blockchain blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. The definition of supply chain is: around the core enterprise, from the supporting parts to the intermediate procts and final procts, and finally by the sales network to deliver the procts to consumers, it is a whole functional network chain structure from suppliers, manufacturers, distributors to the end users.

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 />

6. The hierarchical structure of blockchain
1, data layer / data layer
the data layer mainly describes the physical form of blockchain, which is a chain structure starting from Genesis block on blockchain, including block data, chain structure, random number, time stamp, public and private key data on blockchain, and is the lowest level data structure in the whole blockchain technology
2. Network layer / network layer
the network layer mainly realizes the mechanism of distributed network through P2P technology, and the network layer includes P2P networking mechanism, data dissemination mechanism and data verification mechanism. Therefore, blockchain is essentially a P2P network with automatic networking mechanism, and the communication between nodes is maintained by maintaining a common blockchain structure
3. Consensus layer / consensus layer
consensus layer mainly includes consensus algorithm and consensus mechanism, which enables highly dispersed nodes to reach consensus on the effectiveness of block data efficiently in the decentralized blockchain network. It is one of the core technologies of blockchain and also the governance mechanism of blockchain community. At present, there are at least dozens of consensus mechanism algorithms, including workload proof, rights and interests proof, rights and interests authorization proof, burning proof, importance proof and so on
data layer, network layer and consensus layer are the necessary elements of building blockchain technology. Without any layer, it can not be called a real blockchain technology
4. Incentive layer / activator layer
the incentive layer mainly includes the issuing system and distribution system of economic incentive. Its function is to provide certain incentive measures, encourage nodes to participate in the security verification work in the blockchain, incorporate economic factors into the blockchain technology system, encourage nodes that comply with rules to participate in bookkeeping, and punish nodes that do not comply with rules
5. Contract layer / contract layer
the contract layer mainly includes various scripts, codes, algorithm mechanisms and smart contracts, which is the basis of block chain programming. Embedding the code into the blockchain or token, realizing the smart contract that can be customized, and automatically executing without a third party when certain constraints are met, is the foundation of the blockchain's distrust
6. Application layer / application layer
the application layer of blockchain encapsulates various application scenarios and cases, which are similar to applications on computer operating system, portals on Internet browsers, search engines, e-malls or apps on mobile phones. The blockchain technology applications are deployed on Ethereum, EOS and qtum, and are implemented in real life scenarios. The future programmable finance and programmable society will also be built on the application layer
incentive layer, contract layer and application layer are not necessary factors for each blockchain application, and some blockchain applications do not completely include the three-tier structure.

7. B91 is not bad, do yellow pages, more complete information. If you are new to blockchain, their website is a relatively comprehensive and complete blockchain database, which is more suitable for you to use when looking for some projects and services.

8. In the past, when you want to access the data of company a, you have to request the database of company A. this center is the database of company A. now, blockchain is where you access the data and request the data of each client in a certain area, because the data is stored on all clients and must match the data of all clients in the area, It's meaningless to change only one client data. I understand that's about it

9. First, the POS + pod hybrid consensus mechanism of the exclusive game community greatly improves the efficiency and consistency of the public chain network
Second, community autonomy. All decisions are made by community members. Under the hybrid consensus mechanism, both POS krypton players and pod technology players have higher yield and discourse power, which effectively avoids the impact of centralized computing power and financial resources on the whole game ecology, and thus reces the risk of bifurcation. If a node wants to propose a bifurcation for a certain protocol or standard, all nodes need to participate in the voting. If the pod + POS weighted value of the voting result exceeds 50%, the system defaults to the chain with high weighted value as the effective chain, and all nodes will migrate to the new chain mining at the time agreed in the voting result
thirdly, because game players have requirements for the performance and bandwidth of hardware devices, vs public chain sets the node players involved in accounting into two categories: full node and light node. Players can manually switch between full node and light node. Generally, light node mode is adopted in the process of the game to provide more hardware support for the game, and full node mode is started after the end of the game and ring the hang up period
fourthly, all the transaction rights in the game come from the players. Only after the players are authorized by the exclusive secret key, the game assets can be circulated. At the same time, all transaction data are encrypted by ECC (elliptic encryption algorithm), which is a modern cryptography technology, to ensure the information security of blockchain
fifthly, as a vertical public chain in the game field, vs will first complete the overall solution of decentralized game proction, virtual asset distribution and token economy operation. It includes game engine, developer environment, standard SDK, etc., which reces the difficulty and threshold for game developers to enter blockchain game development from various environments, greatly reces the workload and cost of game development team, and also makes vs public chain highly scalable.
