Account activeness perceived block chain world state dynamic construction method and system

Abstract

The invention discloses a block chain world state dynamic construction method and system based on account activeness perception, and the method comprises the steps: calculating the activeness of an account of which the state is changed in a block, dividing an active account and an inactive account, and constructing an active account table; an active account state table is constructed according to the accounts with the changed states and the states of the accounts; receiving a transaction executed in the current block, and dividing account properties of accounts with changed states in the transaction according to the active account table so as to construct a world state tree; and updating the active account state table according to the account with the changed state in the transaction and the latest state of the account, judging whether the account properties of the target account in the current block and the previous block are converted or not, adopting a corresponding branch conversion strategy according to the conversion of the account properties, and updating the world state tree according to the branch conversion strategy. The problems that along with exponential growth of Ethereum state data, storage space is increased, and query and updating efficiency is reduced are solved.

Description

A method and system for dynamically constructing the blockchain world state based on account activity perception technical field [0001] The present invention relates to the technical field of block chain state organization, and in particular, to a block chain with account activity perception World state dynamic construction method and system. Background technique The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art information. technique. [0003] Blockchain is a distributed and decentralized computing and storage architecture. Typical blockchain platforms use Bitcoin using the UTXO model and Ethereum using the account model. In Ethereum, a transaction is the amount of information that Ethereum is based on According to the data unit, the essence of system operation is to process transactions and update the status of the entire network. The full Ethereum state refers to all...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the above-mentioned problems, the present invention proposes a method and system for dynamically constructing blockchain world states that are aware of account activity. Aiming at the problem of exponential growth in world state accumulation, the influence of different activity levels of accounts is considered to solve the problem of Ethereum state data is growing exponentially, which brings problems of increased storage space and lower query and update efficiency
