Block chain fine-grained editing method supporting rapid state updating

Abstract

The invention discloses a block chain fine-grained editing method supporting rapid state updating, and the method comprises the steps: for each transaction executed by an editable block chain for the first time, generating a rapid execution code of the transaction according to the execution process information of the transaction, and recording a read set and a write set of the execution process of the transaction; after an editing event that a block chain editing authority owner edits a certain historical transaction on a block chain occurs, transactions of which the states of read set elements are changed compared with those in the first execution are optimally executed in parallel, and the execution of the transactions is accelerated by using a quick execution code generated in the first execution of the transactions. And after all transactions in a certain block B are updated, state tree, transaction tree and receipt tree information in the block heads of the block B and all blocks which are influenced by the update before are updated in parallel. According to the method and the device, the time and computing resources required by updating the state of the block chain node after the editable block chain node performs the editing operation can be reduced, and the performance of the editable block chain is improved.

Description

technical field [0001] The invention belongs to the technical field of blockchain, relates to the execution process of blockchain transactions, the storage process and storage structure of blockchain data, and specifically relates to a blockchain fine-grained editing method that supports rapid status update. Background technique [0002] The blockchain is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces", "traceable", "open and transparent" and "collective maintenance". However, the traditional blockchain technology lacks the ability to supervise the data on the chain, and some illegal information cannot be deleted after being uploaded to the blockchain. Therefore, the concept and technology of editable blockchain is derived. [0003] For editable blockchain, according to the different data editing objects, it can be divided into block-level, transaction-level and data item-level editing operations. The block...

AI Technical Summary

Problems solved by technology

In the process of blockchain nodes re-executing transactions to update the state, the stability and correctness of the global state data of the blockchain cannot be guaranteed

Therefore, during the state update period, the blockchain cannot perform normal block operations, which affects the performance and usability of the editable blockchain

[0005] However, the existing research on editable blockchains only involves the agreement to reach a consensus on an editing behavior in the whole network, and there is no effective strategy for the state update behavior in actual execution.
