All blockchain makers need p-notes

1.

We need to establish data layer, network layer, consensus layer, incentive layer, contract layer and application layer

1. The data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and time stamp

2. The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism

The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes

The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuing mechanism and distribution mechanism of economic incentives

5. The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain

6. The application layer encapsulates various application scenarios and cases of blockchain

, general secretary of the CPC Central Committee, stressed in the eighteenth collective learning of the Central Political Bureau, "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". <

p>

the forward-looking judgment of the CPC Central Committee has brought the "blockchain" into the public view and become the common focus of financial capital, real economy and public opinion

from network power to big data, from media integration to blockchain, the Politburo of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, showing the direction, foresight and foresight of the CPC Central Committee, leading the pace of China's instrial change and economic transformation. This collective study of the Political Bureau of the Central Committee of the CPC, with special emphasis on "blockchain", has opened up an imaginary space for the development and application of blockchain

from the perspective of science and technology, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the perspective of application, in short, blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent

these features ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry, and realize the cooperative trust and concerted action among multiple agents

2.

Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade

extended data :

1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

3. Blockchain was born in bitcoin. It is a decentralized database. As the bottom layer of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction. Here you can recommend a better practical application scenario of combining physical jewelry and blockchain technology. Domenech's Maobei digital virtual currency, please adopt

4. It depends on what standard you want and what kind of company you choose
I think Shengshi Huacai has a good price performance ratio
the price of blockchain is not very expensive

5. Jinwowo analysis believes that: first of all, blockchain technology is not just a technology, but an organic combination of cryptography, P2P network communication, consensus algorithm and other technologies, and the technologies involved have basically appeared long ago
in a word, jinwowo thinks that this technology can solve many problems, but not every problem is suitable for blockchain technology! Moreover, blockchain technology itself is still in the development stage, and there are still many bottlenecks to overcome. If there is popularization in the future, it will have the same subversive impact on human society as the Internet
in the future, jinwowo will continue to tap the value of blockchain technology in the commercial field and give full play to the advantages of big data services

6. No, blockchain is very extensive. Some of them are games and limited transactions. Mining is not equal to blockchain

7. Safety still needs to understand the platform carefully, including the risk control measures of the platform. As long as you want to choose a bank deposit, performance insurance, but this is for investment.

8. Fish three flowers or one or nine, Aquarius according to the tips in the card city run this plane that trumpet, Capricorn a kind of attribute BB like fire, Sagittarius go to each continent once or kill leiyinwu Gobi monster once, Scorpio 400 card or the last ten answers, you row a number in the top ten, get a card or kill dozens of monsters, Libra with gold or random back to the city to draw, It's easy for Virgo to ride a pet and let it see. The lion needs to prepare or kill 5 in advance to kill guards or select 3 places in the hall of fame. The Gemini shopping God is easy to do. The cancer is killed once or several times and 1000 blood is prepared. The Taurus digs more in advance. Each time is different. The Aries is not easy to do. If it's good for double experience, the second time may be double attack

9. The project of currency win alliance is OK, aiming at the good project of currency win alliance, and the technology is OK.

10. I am a relevant person in the blockchain instry and can answer your questions. Blockchain first expanded from the field of encrypted digital currency to other fields. For example, the financial instry is now maturing
other areas are also under exploration, such as Shanghai wangchain technology, which has applied blockchain to agriculture, finance, food and other instries.
