1. blockchain does not belong to any instry. 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. 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.
2. From the perspective of data, blockchain is a kind of distributed database or distributed shared general ledger. The "distributed" here is not only reflected in the distributed storage of data, but also reflected in the distributed records of data. From the perspective of effect, blockchain can generate a set of time sequence, tamper proof and trustworthy database
blockchain has four core technologies. The first one is block + chain, which is the most core and basic technology in blockchain. The second core technology is distributed structure. The ingenious design of blockchain structure is to let every node participating in data transaction record and store all data. The third core technology is asymmetric encryption algorithm, and the fourth core technology is script, which can be understood as a programmable smart contract.
3. Seeing some answers to the debate on the definition of blockchain, I suddenly realize that my answer to this explanation principle has always been directed at bitcoin. There is no specific and unique answer in the instry between the definition of blockchain. Here I first summarize the characteristics of "blockchain" according to the papers I read:
1; Hash chain & quot There are several nodes participating in the system operation (distributed)
3. Reach a consensus on the consistency of basic data (consensus agreement / algorithm) through a certain protocol or algorithm
since bitcoin is currently one of the most typical and influential applications of blockchain, it will be much easier to understand how bitcoin uses blockchain before understanding other forms of blockchain applications
4. Blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.
5. Blockchain is a decentralized point-to-point transmission of distributed books, a technology based on consensus mechanism. Hashton blockchain training institutions are very good. You can learn about them.
6. He was the first bitcoin underlying technology to realize the sharing mechanism of point-to-point transmission of distributed data storage, so as to achieve the transparency and security of transactions. For example, six degree chain is actively introcing this technology. I think it is quite reliable.
7. Under the background of Internet, when we need to exchange value with unfamiliar adversaries, how can we prevent people from being deceived and confused by malicious saboteurs, so as to make wrong decisions. Shengshi Huacai, our company's partner, is very good at blockchain. His family is a professional financial IT solution and technical service provider. You can contact them if you need
8. What kind of blockchain technology is popular recently? Blockchain technology is considered to be the brightest star in financial technology, and it may continue to develop in the future. It has many characteristics, including data distribution, data trust and collective consensus mechanism, and most importantly, openness, transparency, anonymity and privacy, According to the data in the blockchain, we can get some basic information of contemporary society
blockchain technology is such a safe and scientific database. It can be simply understood as an authoritative database, in which the basic content is true, verified and audited by others. In terms of financial technology, it is very easy to find some desired data, which is very good for business people
9. It is impossible to use the central bank's
digital currency to increase the risk of residents' information security. The central bank's digital currency is generally stable and traceable
