Does blockchain need cabinets

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

3. Blockchain itself is decentralized, either for indivials or teams. It doesn't have to be a company. If your project needs to be engaged in offline business, you need to register a company. However, if you are engaged in pure blockchain network, there is no need to set up a company. For example, the well-known hummingbird strategy Arbitrage (HMT. One) is carried out between different exchanges.

4. According to the current talent demand in the blockchain field, it can be roughly divided into the following categories:
1. Build a distributed ledger application based on DLT technology to realize the business requirements of customers on DLT. At present, the more famous one in this field is REBO. So what does DLT mean? Just look at what REBO is doing
2. Develop your own application on the existing public chain. At present, most companies are doing this. This category is also characterized by low threshold, high business potential and low risk
3. Companies develop their own public chains, which have the greatest potential in the future, but also have the highest risks and technical difficulties
4. Blockchain ecological infrastructure. For example, mobile wallet, hardware cold wallet, trading platform, blockchain content platform and so on are the blockchain instries with the highest commercial profits at present. Relatively speaking, the threshold is low and the risk is low, but there are many competitors
if we start from technology, what languages and knowledge do we need to learn
for the first class, go language is necessary, because DLT is mainly based on go language, and it also needs to master certain application development ability, because it must be a piece of software rather than a bunch of command-line source programs delivered to customers. For the second category, the mainstream of smart contract is the solidness language of Ethereum smart contract, so if you want to enter the second category of enterprises, you need to start with Ethereum. The third type of public chain development, the mainstream is C + + and go, but there are also many famous projects are implemented in trust, such as: Facebook's Libra, fire coin's nervos and so on. In fact, the fourth category has little to do with blockchain technology, because development such as trading platform does not need blockchain technology
in addition to the above technical hard power, blockchain companies prefer "slash youth", that is, talents who master multi field knowledge at the same time, which can be divided into three categories: finance and blockchain, content operation and blockchain, community operation and blockchain. Among them, the third kind of talents is the rarest, because most technical talents are not good at communication and exchange. However, e to its distributed characteristics, blockchain especially needs the joint efforts of the community to create and maintain a chain
in the end, many people mistakenly think that blockchain is a brand new instry, and that blockchain is totally different from traditional fields. This is actually a big mistake. From what has been written above, you can also find that in the end, blockchain still needs to solve the actual needs in reality. The only difference is that the tools to solve the needs have changed, so don't think that only knowing blockchain can kill all sides, It is very important to have the basic knowledge of the requirement field
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.

5. There are no specific requirements. It is recommended to experience the blockchain in bitmax. This platform has strong financial strength, security and technology, so it is very good to choose other countries for blockchain transactions.

6. 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

7. It is stored on the chain, and the data is stored on the server; It's just that the so-called servers are distributed.

8. Bitcoin is a kind of P2P virtual currency. Point to point transmission means a decentralized payment system. Bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole
P2P network to confirm and record all transactions< Bitcoin trading is carried out through bitcoin trading platform,
at present, the better bitcoin trading platforms in China are
okcoin, bitcoin China,
fire coin network, 796 trading network, etc. the capital of each company is different,
okcoin is based on Technology, and fire coin network pays more attention to user experience,
but in terms of professionalism,
okcoin is relatively good.

9. Nowadays, blockchain and artificial intelligence have become an eye-catching field. At present, many instry giants at home and abroad are competing in the field of blockchain, and the stocks of listed companies that have announced their involvement in this field are also rising. Although there are still uncertain factors in policy and other aspects, blockchain is undoubtedly the next instry dark horse< First, when registering a blockchain company, let's first understand what the business scope of the blockchain company is:
1. Technology development, technology transfer, technical consultation, technical services, business consultation, enterprise management, marketing planning, real estate brokerage, enterprise marketing planning, conference services in the field of network information and computer network technology, Exhibition services
2. Engaged in technology development, technical consultation, technical service, technology transfer, computer system integration, computer data processing, computer network engineering maintenance, digital works database management, self owned equipment leasing, computer software research and development, cloud infrastructure services, enterprise management consulting in the field of computer network technology and computer software and hardware technology, Business information consulting, enterprise management, corporate image planning, exhibition services, photography, design and proction of all kinds of advertising, using its own media to publish all kinds of advertising, computer software and hardware and auxiliary equipment, communication equipment sales, engaged in the import and export business of goods and technology, trade brokers and agents
3. Development and application of blockchain technology; Big data R & D and technology promotion; Technology development of electronic currency and game currency; Health instry investment (specific projects will be declared separately); Commemorative coin design; Conference and exhibition services; Sales of cultural artworks (except ivory and its procts); The development of digital integral system; Cultural exchange activities planning; Domestic trade; Import and export business< Second, how to register a blockchain company
1. A company registered by name verification must first have a name. According to the enterprise name verification disclosed by the instrial and commercial registration bureau, the name registration rate related to blockchain is on the rise. Therefore, entrepreneurs who want to show their talents in the blockchain instry should quickly think of a good name
2. Apply for the license materials, sign and make the application materials of the registered company, provide the identity information of the legal person, shareholders and supervisors, determine the shareholding ratio of shareholders, the amount of registered capital, business scope, etc., verify the identity cards of the legal person and supervisor of shareholders, and submit the signed application materials to the Administration for Instry and commerce. At the same time, the ID card of the person in charge of finance should be provided
3. Apply for a business license and submit the signed registration materials to the instry and Commerce Department for review. After the review, you can get the business license
4. To open a company's basic bank account, a company needs to provide the original and plicate of its business license, official seal, financial seal, corporate seal and ID card of its legal representative to open a basic bank account. You can get a license to open an account in about two weeks
5. After the tax type is approved and the bank account opening license is obtained, prepare the tax verification data. Need business license, official seal, bank account opening license, business address of housing lease contract, housing lease invoice, digital certificate, and need to do information online now, print out after passing. Take this information with you to check the tax
6. When purchasing an invoice, the tax agent should bring his / her original ID card, tax agent card, official seal, invoice seal and Golden Tax plate to the tax hall for collection.
