Abstract
Implementations of this specification include identifying a plurality of transactions to be executed in the blockchain, wherein the transactions are arranged in an execution order, wherein the transactions include one or more smart contract calls to smart contracts each having a whitelist identifying one or more accounts that are authorized to execute the smart contract, and wherein the execution order includes a smart contract call to a smart contract that does not have a whitelist arranged after the plurality of transactions; identifying groups of transactions within the plurality of transactions; instructing nodes of the blockchain network to execute each of the groups of transactions in parallel; determining that the nodes of the blockchain network have completed executing all of the groups of transactions; and in response, instructing the nodes of the blockchain network to execute the smart contract call that does not include a whitelist.
