Method and system for collecting operation states of main chain and sub-chain of block chain, and storage medium

Abstract

The invention relates to the technical field of block chains, and particularly discloses a method and system for collecting operation states of a main chain and a sub-chain of a block chain and a storage medium, an alliance chain network is constructed, and the alliance chain network comprises a main chain and more than one sub-chain; a state collection smart contract is deployed in the main chain, wherein the state collection smart contract is used for collecting state data of the sub-chain; the sub-chain participating organization has a write permission for the state collection smart contract on the main chain; the current sub-chain participating organization submits the state data by calling the state collection intelligent contract of the main chain, and the main chain broadcasts the collected state data of the current sub-chain organization to a block chain network; other sub-chain participated organizations acquire the state data by monitoring the state collection smart contract of the main chain; therefore, the main chain monitors the operation state of the sub-chain, and the stability and controllability of the operation of the block chain system are improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method for collecting the operating status of main and sub-chains of block chains and a system and storage medium for applying the method. Background technique [0002] The traditional blockchain is a single-chain structure, and each ordinary node in the blockchain must store all states, execute all transactions serially, and reach consensus with all other machines. Once the mainnet is launched, it can only be repaired in a small way, and there is no way to upgrade it on a large scale. In terms of blockchain technology, security and performance on the same chain are contradictory. However, the tasks of the blockchain are diverse. The transfer of digital currency Token has high security requirements, but the asset certification business is not so sensitive to security and pays more attention to efficiency. It is difficult to take care of both in one chain, even if ...

However, the tasks of the blockchain are diverse. The transfer of digital currency Token has high security requirements, but the asset certification business is not so sensitive to security and pays more attention to efficiency. It is difficult to take care of both in one chain, even if Even the later side chain technology is not very useful for alleviating the pressure on the main chain (the side chain uses the interface of the main chain to develop a blockchain project that suits its own technical requirements or its own functions, but the side chain must have A considerable amount of computing power can guarantee the security of the side chain currency. It can be seen that the computing power requirements are relatively high, and there are hidden dangers in security)
