Problems solved by technology

However, in the actual application process of the above-mentioned certificate storage technology, the rate of business data to be stored may not match the rate of deposit certificates. Publishing transactions to the blockchain while waiting, adversely affecting business performance
[0003] In related technologies, data uplink can be completed in an asynchronous way. In this case, the business side does not need to wait for the server to publish the execution result of the transaction to the blockchain, so it can reduce the impact of synchronous uplink on the business. Adverse impact on performance; however, in the case of using the above method, if the deposit service used for on-chain certificate deposit fails, it may lead to data loss, certificate invalidation and other consequences

Abstract

The invention discloses a data evidence storage method and device, and the method is applied to a server connected with a block chain, and the server carries an evidence storage service for storing data on the block chain. The method comprises the following steps: under the condition that an evidence storage service fails, acquiring to-be-stored data which fails in evidence storage; creating a compensation transaction corresponding to the to-be-stored data, and storing the compensation transaction into a preset compensation transaction queue; and after the evidence storage service fault is recovered, obtaining any compensation transaction from the compensation transaction queue, and sending the any compensation transaction to the block chain through the evidence storage service, so that to-be-stored data corresponding to the any compensation transaction can be stored on the block chain.

Description

technical field [0001] This specification relates to the field of computer applications, in particular to a data storage method and device. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. Among them, data storage is an important application of blockchain technology; in business processing, the server connected to the blockchain usually needs to generate a transaction carrying business data and publish it to the above-mentioned blockchain, so that the above-mentioned business The data is stored in the aforementioned blockchain. However, in the actual application process of the above-mentioned certificate storage technology, the rate of business data to be stored may not match the rate of deposit certificates. Publishing transactions to the blockchain while waiting, adversely ...
