Re: Peer communication during chaincode execution
Kimheng SOK
Hi, My usecase is chaincode need to call external program, in the case of multiple peers, each peer could produce non-deterministic result and the invoke function will return Error: Could not assemble transaction. So all peers need to communicate with each other about the result and compute deterministic result so that the error will not happen. This feature could open the possibility to avoid all peers just passively receiving the deterministic result from a client or central entity. For sure the computation time will increase, because the more peers we have, the more communication need to be done just like gossip protocol. So it is a trade-off . The good news is hyperledger is a permission blockchain, so the number of peers is limited depend on the use case, so some applications could be useful to have this feature. Bests,
