FIELD: computer equipment.
SUBSTANCE: invention relates to computer engineering. Technical result is achieved by identifying a group of transactions in a plurality of transactions, wherein transactions in each group are associated with a specific set of accounts in a network of blockchains, wherein a specific set of accounts associated with each of said one or more calls to smart contracts is determined based on the white list associated with that call in the smart contract; instructing network nodes of blockchains to perform each of groups of transactions in parallel, wherein execution of each group of transactions includes execution of transactions within the group sequentially and according to said order of execution; determining, that nodes of network of blockchains completed execution of all groups of transactions; and in response to determination that network nodes of blockchains completed execution of all groups of transactions, instructing network nodes of blockchains to perform said call in a smart contract, which does not include a white list.
EFFECT: technical result is higher transaction processing speed.
