A computer-implemented system and related method address malfunctioning peers in a blockchain, the method comprising receiving endorsement results from peers in the blockchain, where the endorsement results are for one or more transactions in the blockchain. The endorsement results include successful and failed endorsements. The method further comprises distributing the successful and failed endorsements to two or more endorsement collectors, determining which peers are successful endorsement peers (SEPs) that provided successful endorsements, and which peers are failed endorsement peers (FEPs) that provided failed endorsements. A reputation score is calculated for each peer based on endorsement information from the endorsement collectors. The reputation score is then sent to at least one of a client and a system administrator. This reputation score is then used to determine peer selection in a subsequent transaction.
