Description
Technical Field
The invention belongs to the technical field of block chain systems, and particularly relates to a block chain distributed database-based sharing mechanism.
Background
The blockchain is a novel application mode of decentralized distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and other computer technologies. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system. The block chain technology development goes through three stages in total: the first stage of the currency block chain technology represented by bitcoin, the second stage of the concordance block chain technology represented by Ethengfang and the third stage of the super account book project technology for realizing complete authority control and safety guarantee.
Wherein the decentralization is: the peer-to-peer communication technology is an internet technology of peer-to-peer links, and realizes communication between peer nodes by relying on common computing power and bandwidth of participants in a network. Asymmetric encryption algorithm: the method comprises the steps of using an asymmetric encryption algorithm to realize encryption and signature verification of data, encrypting the data by using a public key, decrypting the data by using a private key, signing the data by using the private key, and verifying the signature by using the public key. The chain data structure: the frequently-mentioned blocks are that index data are stored on each block, the blocks are combined together in a chain mode to form a data structure, and the block header of each block contains the transaction information compression value of the previous block, so that the created block can be linked to the current block, that is, all the blocks contain the reference structure of the previous block, and each block is gathered to form a long chain.
The consensus mechanism refers to that when a plurality of nodes form a network cluster through asynchronous communication, the network is unreliable by default, and a consistency state is formed through a specific mechanism, namely consensus. The consensus algorithm in the platform adopts PBFT, the PBFT algorithm can tolerate less than 1/3 invalid or malicious nodes as malicious nodes, the Byzantine problem under the condition of a limited number of nodes is realized, the fault tolerance of 3f +1 is realized, and certain performance is ensured.
An intelligent contract is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible. The intelligent contracts define and execute the loaded items through code, so that the two parties do not need to establish trust, the intelligent contracts are automatically executed once started, and the intelligent contracts are completely decentralized and do not depend on a single server to automatically run through a network node.
The transaction number per second of the blockchain is 7, which is much lower than the transaction speed of the internet. The transaction verification time is long in bitcoin as an example, and the one-time confirmation time of the current bitcoin transaction is about 10 minutes on average, which is also the generation time of one block. In the case of 6 confirmations, it is necessary to wait for 1 hour, whereas the authentication of a transaction such as a payment treasure requires only a few seconds. (2) Decentralization easily results in that products relying on block chain technology cannot form an authoritative credit endorsement, which for many current business models, if the technology is completely based on decentralization, there is a huge transformation risk, and in the business field, the risk needs to be particularly concerned. (3) And (4) the safety problem of the intelligent contract. The intelligent contracts of the blockchain are visible to all users, so that security vulnerabilities on the blockchain are easily attacked by malicious attacks and may not be repaired quickly, resulting in immeasurable losses.
