Claim 16:
17. A computer program product comprising a non-transitory computer readable medium storing one or more instructions that, when executed by a processor of a client node in a blockchain network, cause the processor to perform:
transmitting an inquiry to a peer in the blockchain network, the inquiry comprising a trigger to invoke a chaincode installed on the peer;
receiving a response from the peer based on an execution of the chaincode by the peer;
