Title:
SMART CONTRACT-BASED CALCULATION, UPDATE AND READ METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/185052
Kind Code:
A1
Abstract:
A smart contract-based calculation method. A smart contract for performing approximate calculation is deployed on a blockchain. The method comprises: receiving a smart contract call transaction for a smart contract initiated by a calculation initiating party, the smart contract call transaction comprising calculation parameters corresponding to approximate calculation, and the calculation parameters comprising a data identifier of a data collection participating in the approximate calculation; in response to the smart contract call transaction, calling a sampling logic comprised in the smart contract call transaction, dividing the data collection corresponding to the data identifier into an outlier data subset consisting of a plurality of outlier data samples and a non-outlier data subset consisting of a plurality of non-outlier data samples, and performing sampling for the non-outlier data samples in the non-outlier data subset; and calling a calculation logic comprised in the smart contract call transaction, performing accurate calculation for the outlier data samples in the outlier data subset, performing approximate calculation on the non-outlier data samples obtained by sampling, and combining the results of accurate calculation and approximate calculation.
