Provided is a system, method, and computer program product for handling fault tolerance in a blockchain enabled network system. The system includes a computing system with at least one of a plurality of processors arranged as an active processor node, at least one data storage device including a first ledger corresponding to a first blockchain and a second ledger corresponding to a second blockchain, at least one standby processor node, and at least one standby data storage device. The at least one active processor node is programmed or configured to analyze and record blocks corresponding to data received through the network system on the first ledger and the second ledger such that the first ledger and the second ledger have matching data, detect at least one failure or anticipated failure, and in response to detecting the at least one failure or anticipated failure, generating a switch-over command.
