Abstract
The system, method, and computer program product described herein provides a built-in feedback mechanism for a blockchain to sanction validator nodes that consistently 'vote' in a manner that does not match the ultimate consensus. The method includes receiving a vote on whether to add a transaction to the blockchain, comparing the vote to a consensus decision on whether to add the transaction to the blockchain, determining based on the comparison that the vote does not match the consensus decision, in response to determining that the vote does not match the consensus decision, incrementing a value associated with the validator node in a feedback registry, determining that the value associated with the validator node is above a predetermined threshold value, and in response to determining that the value associated with the validator node is above the predetermined threshold, proposing a sanction of the validator node to the plurality of validator nodes.
