Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Technical term introduction:
the block chain is a chain data structure formed by connecting data blocks in sequence according to a time sequence, and guarantees a non-falsifiable and non-falsifiable distributed shared general ledger through cryptography. The block in the account book consists of a block head and a block body, wherein the block head encapsulates information such as a previous block hash value, a current block hash value, a mine digging random number, difficulty, a timestamp and a Merkle tree, and the block body comprises transaction information of the current block. The block header of each block stores the hash value of the previous block, so that a chain structure is formed among the blocks. Block chains can be classified into three categories, namely public chains, alliance chains and private chains according to admission mechanisms.
The alliance block chain is generally used among alliance members or organizations, member nodes of the alliance block chain can be joined and quitted only through authorization, the accounting right and the node maintenance right are established through negotiation among the members participating in the alliance chain, the consensus process is also pre-discussed and set, the transaction and the authority on the chain are established according to alliance rules, and compared with a public chain, the alliance block chain is high in transaction speed and low in operation cost.
Consensus algorithm, the goal of blockchain consensus algorithm is to have the data held by all nodes in a distributed network meet consistency and validity. Common consensus algorithms are proof of work (PoW), proof of rights (PoS), authorized shares proof mechanism (DPoS), and authority proof (PoA).
The intelligent contract is a computer protocol which does not need a third party and can be automatically verified and automatically executed according to preset conditions. From a technical level, an intelligent contract is equivalent to a computer program which can automatically execute all or part of contract-related operations and generate verified evidence so as to prove the validity of the execution result of the contract operation, and the process does not need human intervention.
Fig. 1 shows an implementation flow of a block chain-based enterprise credit investigation information processing method according to a first embodiment of the present invention, and for convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

The basic workflow of the PoA consensus algorithm in the federation chain is as follows:
(1) when a alliance block chain is built, a creator designates a group of authoritative nodes signers in a created block as initial authorized nodes according to a set rule (such as random selection and designation);
(2) after the coalition block chain starts mining, signing and broadcasting the generated blocks by the signers appointed in the step (1) in turn;
(3) when a node on the alliance block chain receives a new block, calculating the address of the new block according to the signature of the authentication node in the block head, verifying whether the node is an authorized node or not, and having the authority of signature in the current round, and if the condition is met, determining that the block is a legal block;
(4) and after the members and the number of the signers are changed, updating the address of the signers with the authorized current height in the created block in time, and adding a new authorized node or removing an illegal node in a new round of accounting.
In essence, a smart contract is a computer protocol that does not require a third party, can be automatically verified, and automatically executed according to preset conditions. The operation principle of the intelligent contract is as follows: the contract execution method comprises the steps of encapsulating trigger conditions (such as specific time, specific operation and the like) of contract execution, operation rules, corresponding results (such as output result 1 if condition 1 is met and result 2 is obtained by executing operation 2) under each condition and the like in an intelligent contract, then signing the contract by each participant, attaching the intelligent contract to block chain data in the form of codes after signing is completed, and storing the intelligent contract in a block chain network after a miner packaging verification block in a distributed network. And the block chain system monitors the state change of the intelligent contract in real time, automatically executes the contract after detecting a trigger condition and executes corresponding operation according to an operation rule.
