Title:
SMART CONTRACT-BASED CALCULATING, UPDATING, AND READING METHODS AND APPARATUSES, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/185050
Kind Code:
A1
Abstract:
A smart contract-based calculating method, which is applied to node devices in a blockchain. A smart contract used for executing approximate calculation is deployed on the blockchain. The method comprises: receiving a smart contract call transaction, which is initiated by a calculation initiator, for the smart contract, wherein the smart contract call transaction comprises calculation parameters corresponding to the approximate calculation, and the calculation parameters comprise a data identifier of a data set participating in the approximate calculation; in response to the smart contract call transaction, calling sampling logic contained in the smart contract call transaction, and performing stratified sampling on data samples in the data set corresponding to the data identifier; and further calling approximate calculation logic contained in the smart contract call transaction, and performing approximate calculation on the basis of the data samples obtained by stratified sampling from the data set to obtain an approximate calculation result for the data set.
