Blockchain protocol API
blockchain is a digital account book that can be jointly bookkept, and will record all transactions that have occurred and have been unanimously recognized by the system it's the same as the whole family. You're bookkeeping, and your father and mother are also bookkeeping. They can see the general ledger, but the saved information can't be tampered with any more
In 2008, Nakamoto first proposed the concept of blockchain subsequently, blockchain has become the core component of electronic currency bitcoin, which serves as the public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independentlyextended data:
type of blockchain
1, public blockchain
any indivial or group in the world can send transactions, and transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain. There is only one blockchain corresponding to this currency in the world
2, Alliance (instry) blockchain
instry blockchain: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction, However, regardless of the bookkeeping process (in essence, it is still managed bookkeeping, only distributed bookkeeping, how many preselected nodes, and how to determine the bookkeeper of each block to become the main risk point of the blockchain), anyone else can conct limited query through the open API of the blockchain
3, private blockchain
only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and enjoys the write permission of the blockchain. This blockchain is not very different from other distributed storage schemes
Take a blockchain API tool that I am currently using as an example
previously, I occasionally found bctools , which can quickly and conveniently test and verify BTC and EOS blockchain API. At the same time, these API interface test network and main network can be verified on bctools ; If you are interested, you can go http://bctools.io Use it
at present, Apis on bctools seem to have the following types:
choose your own direction
the cost of developing an interface is not so high. Except for EOS, there is not much data to be chained, which is basically completed locally. As a top blockchain technology developer in China, weisanyun is still a good technology developer.
Help to confirm the rights of digital assets and stimulate innovation vitality
In the era of digital economy, data resources are becoming more and more important. In 2019, China has officially regarded data as one of the seven proction factors as important as labor, capital, land, knowledge, technology and management, and promoted the establishment of data factor market system. However, e to the difficulty of data right confirmation, data traceability and interest sharing, data can not be effectively allocated and circulated in an orderly way, which seriously restricts the development of digital economy
extended information:
precautions:
the trading volume is large, there is an undertaking in the plate, and the seal is strong. The winning rate is relatively higher as a seal. Tomorrow itself is a process of emotional weakness but secondary confirmation. Even if the market recognized seal is not the strongest turnover dragon, the possibility of premium the next day is also higher
the price performance ratio of tomorrow's sale. To put it most simply, if you wait to buy four stocks tomorrow, you only need to catch one that can change hands. Then at least we won't lose money
cognition of short-term players. For short-term trading, the biggest driving force is hot spot, which brings incremental funds. Even in the emotional game, the role played by the short runners is to blow up the bubbles so that they can be profitable. p>
1 - consensus mechanism
2 - distributed data
3 - cryptography technology
4 - Smart contract
5 - authentication access
6 - node management, etc.
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. Blockchain is equivalent to the Internet in the 1990s. Bitcoin, Puyin and other digital currencies are applications of blockchain.
