Blockchain-based transaction management method and system

Abstract

The present invention provides a blockchain-based transaction management system and method, wherein the bookkeeper responds to receiving a sub-chain generation message from an authoritative party, and generates the first zone of the sub-chain indicated by the sub-chain number in the message block, and record the sub-chain generation message into the block chain indicated by the parent chain number in the message; The sub-account is established for the designated parent account on the sub-chain, and the user can conduct transactions on its sub-chain through the sub-account. In this way, by establishing sub-chains that are logically independent from the main blockchain and accounts on different sub-chains conduct transactions simultaneously, the overall operational efficiency of the blockchain is improved. Moreover, both parties to the transaction can choose to generate a sub-account on a sub-chain with a low transaction volume or fewer blocks, and the payer transfers funds to this sub-chain in advance, thereby significantly increasing the time for the transaction to take effect and speeding up the transaction.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to a transaction management system and method based on blockchain. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed accounting system. Structurally, a block usually includes two parts: a header and a body. The block header is used to link to the previous block, and the transaction information recorded in the block body is all the value exchange activities that occurred after the previous block was formed and before the block was created. This feature ensures the integrity of the database. Every piece of transaction data on the blockchain can be traced back to the source through the structure of the "blockchain" and verified one by one. [0003] The blockchain solves the problems of decentralization and trustles...

Problems solved by technology

However, as the scale of the blockchain continues to expand, the waiting time required to upload transaction data to the chain will also increase with the growth of the length and scale of the blockchain, that is, it takes a long time for the transaction to take effect. Transaction speed and blockchain usage efficiency have a big impact
