Main chain storage method and system based on blockchain intelligent contract and storage medium

Abstract

The invention discloses a main chain storage method and system based on blockchain intelligent contract and storage medium, and the method comprises the steps of enabling a side chain evidence storageperson to generate an evidence storage service account and a private key on a block chain main chain, and transfer funds to the account; deploying a Relay evidence storage contract on the main chainby using the main chain evidence storage service account; deploying a main chain evidence storage module on a side chain evidence storage person node, periodically acquiring new block head informationof a side chain and storing the new block head information to a main chain Relay evidence storage contract; deploying a main chain storage verification service module at a local node of a side chainuser, obtaining a transaction hash value needing to be verified and a verification parameter of the transaction, and calling a verification method in a Relay storage contract on a main chain to judgewhether the transaction is stored in the main chain or not. Main and side chain data storage and verification are achieved based on the intelligent contract, the main chain capacity expansion problemis solved, meanwhile, the side chain credibility and reliability are guaranteed, and the method can be widely applied to the field of block chains.

Description

Technical field [0001] The present invention relates to the technical field of blockchains, in particular to a method, system and storage medium for main chain certification based on blockchain smart contracts. Background technique [0002] Blockchain is the basic supporting technology of Bitcoin. It first appeared in the article "Bitcoin: apeer-to-peer electronic cash system" (Bitcoin: a peer-to-peer electronic cash system) written by Satoshi Nakamoto, which is described in detail in the article How to establish a decentralized, non-trust-based point-to-point transaction system implementation method, but actually did not clearly propose the definition and concept of blockchain. According to the definition on Wikipedia (Wikipedia), it compares the blockchain to a distributed database technology. By maintaining the chain structure of data blocks, it can maintain a continuously growing, non-tamperable data record. The characteristics of the distributed database of blockchain are d...

Problems solved by technology

However, the existing interoperability solutions between blockchains are all focused on realizing the value transfer of the public chain, and rarely take into account the use of cross-chain technology solutions to enhance the credibility of the alliance chain or private chain and expand the capacity of the public chain, that is, to use cross-chain The chain technology solution stores the data information of the alliance chain or private chain on the public chain, thereby enhancing the credibility of the alliance chain or private chain, and at the same time, migrates a large number of complicated transaction processing to the alliance chain or private chain to overcome the public chain. transaction inefficiencies
