Data caching method and device based on block chain, electronic equipment and medium

Abstract

The embodiment of the invention provides a data caching method based on a block chain, a data caching device based on the block chain, electronic equipment and a computer readable storage medium. Thedata caching method comprises the following steps: establishing a global cache, wherein the global cache is used for storing data read from a disk; reading account data corresponding to the to-be-processed block from the global cache; executing the transaction in the to-be-processed block according to the account data; and updating the account data in the global cache based on the transaction execution result. According to the technical scheme of the embodiment of the invention, on one hand, the data reading duration can be reduced through the method, so that the data reading efficiency is improved, and on the other hand, the I / O interaction frequency can be reduced through reading the data from the global cache, so that the transaction execution efficiency of the block is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of blockchain, and more specifically, embodiments of the present invention relate to a data caching method based on blockchain, a data caching device based on blockchain, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the rapid heating up of blockchain technology, its technology and application scenarios have received more and more attention. As a representative of blockchain 2.0, Ethereum provides a distributed platform that can run smart contracts. Among them, the Ethereum Virtual Machine (Ethereum Virtual Machine, EVM) applied to Ethereum is a Turing-complete 256-bit virtual machine, which provides better certainty, termination and isolation for smart contracts. [0003] At present, during the operation of Ethereum, it is necessary to read the relevant transaction data of the current block from the disk. However, if each time a new b...

[0003] At present, during the operation of Ethereum, it is necessary to read the relevant transaction data of the current block from the disk. However, if each time a new block is generated, it is necessary to read the transaction data related to the current block from the disk Transaction data will cause frequent data reading from the disk, which will lead to a high number of interactions between the central processing unit (Central Processing Unit, CPU) and the disk’s input / output (Input / Output, I / O), making Block transaction execution efficiency is not high
