What is the blockchain technology? It's finally coming

1.

In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography

broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contracts composed of automated script code to program and operate data

working principle

blockchain system is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and timestamp; 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 issuance mechanism and distribution mechanism of economic incentives; The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain; The application layer encapsulates various application scenarios and cases of blockchain. In this model, chain block structure based on timestamp, consensus mechanism of distributed nodes, economic incentive based on consensus computing power and flexible and programmable smart contract are the most representative innovations of blockchain technology

2. What is blockchain? Blockchain is a kind of distributed shared accounting technology. What it needs to do is to enable all parties involved to establish a trust relationship at the technical level. Blockchain can be roughly divided into two levels, one is to do the underlying technology of blockchain; The second is to do the upper application of blockchain, that is, the transformation, optimization or innovative application based on blockchain. Blockchain is still in its infancy. Many people are discussing with me how to guarantee both rights and privacy. Of course, now they are just exploring, which means that the content of the whole network should be fair and clearly protected. That's all I can say. This is how I will arrange it in the future

blockchain concept? The idea of blockchain is to completely decentralize and rely on distributed justice. In that case, the cost will drop a lot in theory, proving that the real assets and property rights are directly corresponding on the Internet. After solving the problems of decentralization and asset ownership that the first generation of Internet information did not solve, how much role does big data play in financial innovation? Only by using big data to register can we know who it belongs to. In fact, this has always been a problem that we can't solve now. It's not a small problem. Any technology in the capital market that makes clear the property rights of things that are not clear about the property rights is a huge change for the whole market

what is a blockchain? Blockchain technology itself can solve data ownership, pricing and sharing mechanism. There are still some problems that can not be completely solved. For a simple example, when it comes to user privacy, I have a data on the machine, and the partner comes and makes an insurance to analyze the cooperation. Here is a risk to be given or not to be given, whether it can be dealt with, or whether the property right of the laboratory can be clearly divided, and then the processing right and the data right can be clearly stated, It's common for all of us to proce common procts. We need to divide different things, how to price and how to divide them. In addition to the technology of blockchain, a distributed database, the above is a new task, which is another problem, and then the problem of pricing, which is the problem of market mechanism, which is proved and approved by all fields, So I think blockchain is a very good core technology, but it can't cover all the problems

Introction to Bubi blockchain

Bubi blockchain is mainly positioned to provide commercial level blockchain infrastructure services, mainly including building a blockchain system and building a supporting system with high scalability on the blockchain system. And the support system above is the application of all walks of life. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, almost all the energy of the team of more than a dozen people has been devoted to the research and development of the underlying technology. The reason why Bubi blockchain chooses points has something to do with the promotion method of the market. As we all know, blockchain is a very suitable technology for digital asset issuance and trading. Integral is a kind of natural legal and compliant digital asset, which has little impact because of its small amount. So it's a very suitable choice to take points as the first attempt of digital asset issuance. Issuing points based on blockchain can also bring great help to the circulation and exchange of points

what is a blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to recing the cost of property transfer, blockchain technology can also be applied to various fields, such as company stocks, financial derivatives and points planning of commercial institutions. At present, blockchain community is focusing on promoting the wider application of this technology in the field of financial assets, and related platforms that are still under development have also received considerable investment

blockchain concept? In terms of structure or definition, these things are very different. The U.S. dollar, or any currency, by definition, is mainly used as a medium of transaction or a store of value for economic activities. Within the geographical scope of a certain currency circulation, people in the region reach a consensus on the use of this currency, which is convenient for people to use the same currency to purchase goods or services (the function of currency as a trading medium). We have the responsibility to manage money through monetary policy, so as to ensure the value of money and avoid inflation (the value storage function of money). In today's world, almost everyone uses some kind of currency in their daily life

what is a blockchain? Even developers in the blockchain community tend to ignore the grand picture mentioned above. There are many competitive projects in the blockchain community, which are also full of disputes about the evolution direction of blockchain technology. Over time, some projects in the community will succeed, others will not be so lucky. Things will not always develop in the direction we expected. However, no matter how these projects in the early blockchain community develop, it has been very clear that blockchain technology has brought us at least one revolutionary function: blockchain technology will greatly rece the cost of financial property transfer, and blockchain will be used to control Manage and distribute financial assets

what is a blockchain? Blockchain concept? After a certain application analysis, we will go back to the starting point. The definition of blockchain technology will become more and more abundant with the development of application. People will find more mysteries of blockchain technology.

3. Who can say, how about mining? Mining refers to the use of bitcoin mining machine to obtain bitcoin, that is, the computer used to earn bitcoin. If you can get bitcoin, you can make money. This kind of computer generally has professional mining chips, and works by installing a large number of graphics cards, which consumes a lot of power. The computer downloads the mining software and then runs a specific algorithm to get the corresponding bitcoin after communicating with the remote server< First, the principle of Mining:
1. As long as there is a computer that can access the Internet and download the bitcoin program from the bitcoin website, the first run will generate a digital account, and then keep running, the program will continuously calculate a series of "mathematical problems". When you have successfully calculated "a mathematical problem", the, It's possible to get a certain amount of bitcoin
2. Bitcoin is a P2P network. To keep the network running, it is necessary to keep someone uploading and sharing data to others online. Bitcoin network needs someone to contribute computer resources for computing to ensure the operation of bitcoin network. Therefore, bitcoin is designed that whoever contributes computing power to keep the network running can get the fee paid by the network bitcoin< Second, mining security mechanism:
Mining creates a competition mechanism equivalent to lottery, and it is very difficult for anyone to continuously add new trading blocks to the block chain. This mechanism can prevent any indivial from obtaining the ability to freeze certain transactions, thus ensuring the neutrality of the network. This mechanism can also prevent any indivial from replacing part of the block chain to rece their own costs
precautions:
1. It's better to do DIY mining machine by yourself, from purchasing accessories to assembling, and then to mining software, to learn, focus, practice and graally understand the blockchain
2. Mining is actually a fixed investment process: regardless of the currency price, a certain amount of positions will be increased every day
3. The bitcoin wallet used to store bitcoin uses military level encryption, which makes it impossible for hackers to steal easily. Bitcoin wallet also allows users to set two passwords, a public account password and a private password. The user of public account password is to let the user receive bitcoin. If users want to withdraw or transfer bitcoin from their accounts, they need to use a private password.

4. Explain blockchain with scientific language --- blockchain is a permanent and irreversible modified record generated by superimposing encrypted data (blocks) in chronological order. Many financial institutions in the world, including JPMorgan Chase, HSBC, Citibank and New York Mellon bank, have also cooperated with blockchain companies to study the application of blockchain technology in the financial market. The person in charge of the blockchain Technology Laboratory of Shanghai Heshu software said that when there is no trusted third party in blockchain, all transaction data will be stored in a data block, and the transaction information will form a complete chain and be included in the blockchain, which is a more reliable ultimate solution than the trusted third party.
