This permits bitcoin software program to find out when a selected bitcoin quantity has been spent. For example, if A1 needs to entry the smart contract chaincode S5 on peer nodes P1 or P2, every peer node uses its copy of CC1 to determine the operations that A1 can carry out. For instance, A1 could additionally be permitted to read or write knowledge from the ledger L1 in accordance with policies defined in CC1. We’ll see later the identical pattern for actors in channel and its channel configuration CC2. Again, we are able to see that while the peers and applications are important actors within the community, their behaviour in a channel is dictated extra by the channel configuration coverage than another issue.
