Privacy calculation method based on smart contract in block chain and related equipment

Abstract

The invention provides a privacy calculation method based on a smart contract in a block chain and related equipment. The method comprises the following steps: calling encrypted data and a digital certificate of each participant in a plurality of participants involved in a computing transaction in response to determining that the computing transaction contained in the smart contract in the block chain meets a trigger condition, decrypting the encrypted data by using the digital certificate to obtain the original data of the participant; and based on all the original data, executing calculation logic corresponding to the calculation transaction to obtain a calculation result. According to the privacy calculation method based on the smart contract in the block chain and the related equipment provided by the invention, the security and privacy of the data in the privacy calculation process are ensured through the application of the smart contract system in the block chain, the accuracy and reliability of the data are ensured through calling the non-tampering smart contract calculation, and the user experience is improved. And the problem of data security and trust of the user in the calculation process is solved.

Description

technical field

[0001] The present application relates to the technical field of blockchain, and in particular to a privacy calculation method and related equipment based on smart contracts in blockchain. Background technique

[0002] In the prior art, when the calculation program obtains the calculation result, it needs to obtain all the original data, and then obtain the desired final calculation result through a certain calculation method. However, data ownership and calculation are inseparable, that is, in all cases where raw data is required for calculation, sensitive data and private data of users need to be obtained, so data leakage is prone to occur. Users cannot get the expected calculation results under the premise of ensuring data security and privacy. Contents of the invention

[0003] In view of this, the purpose of this application is to propose a privacy computing method and related equipment based on smart contracts in blockchain.

[0004] Based on the ab...
