Abstract (en)

[origin: WO2022040315A1] Systems and methods to at least provide access control for execution of smart contract functions (methods) through consensus mechanisms are disclosed. A first smart contract is stored on a blockchain network. During execution, the first smart contract performs operations that include: aggregating a threshold number of signed blockchain transactions from authorized blockchain addresses, receiving a set of signed blockchain transactions calling a function of a target smart contract from a set of blockchain addresses, verifying that each blockchain address of the set of authorized blockchain addresses is authorized to make the call, and calling the function of the target smart contract when a number of signed blockchain transactions calling the function exceeds a threshold number.
