Principle of blockchain router
blockchain is an important concept of bitcoin, which is essentially a decentralized database and serves as 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
blockchain is public on the network and can be queried in every offline bitcoin wallet data. The function of bitcoin wallet depends on the confirmation with the blockchain. An effective inspection is called a confirmation. Usually, a transaction needs to obtain several confirmations. The lightweight bitcoin wallet uses online confirmation, that is, it will not download the blockchain data to the device storage
many of bitcoin's competitors also use the same design, but the workload proof and algorithm are slightly different. For example, the use of proof of interest and scrypt and so on
in addition, digital cryptocurrencies such as Laite coin, Ethereum, Weimeng coin, doggy coin and Ruitai coin also use blockchain technology.
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
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
Classification and application of blockchain:
1. According to different scenarios, design systems and attribution, blockchain is generally divided into three categories: public chain (public service), private chain (focusing on the application of an enterprise or instry) and alliance chain (generally belonging to an instry or a supply chain)
2. It is basically divided into three kinds of applications:
< UL >blockchain applications of well-known enterprises: (Netease blockchain cat (games), Xunlei's chain customer, Fengfeng's cool broadcast cloud (BFC points), laikelib and jiajiabao of Heshu software, Renren's social rrcoin, 360's router, and other well-known enterprises)
start up companies based on blockchain (Ethernet wallet, Babbitt, fire coin)
public applications (the bank has set up a research and development laboratory)
the current market situation and development of blockchain:
currently, blockchain applications in the market are mainly issuing "token", realizing "integral management" and pet games, with relatively single functions and few data of blockchain related apps, More are financial apps
