Claim 0:
1. A hardware-implemented network interface device in a blockchain network, the network interface comprising:
a processor that, when executing one or more instructions stored in a memory, is configured to:
cause the network interface device to transmit an inquiry to a peer in the blockchain network, the inquiry comprising a trigger to invoke a chaincode installed on the peer;
receive a response from the peer based on an execution of the chaincode by the peer;
calculate, based on the response, a simulation latency value for a simulation of the chaincode by the peer a round trip latency value based on the transmission of the inquiry and the receipt of the response;
store an identifier of the peer in a list of identifiers of other peers of the blockchain network, where the list of identifiers is ordered based on respective latency values of the identifiers; and
select one or more peers from the list based on the respective latency values to endorse a transaction.
