DYNAMIC MIXED-MODE METHOD FOR COMBINING ACTIVE/ACTIVE AND VALIDATION ARCHITECTURES FOR DISTRIBUTED LEDGERS

A method is provided for performing transaction processing in a system that includes a plurality of nodes. Each of the nodes include a processor, an application executing in the processor, and an instance of a database used by the application. Each node executes transactions. At least two of the nodes are dynamically selected to receive the same request to process a transaction, and the processor at each of the at least two nodes executes and validates the same request to process a transaction. One or more of the at least two nodes replicates the same request, steps and operations, and/or indicia of the transactions to one or more other nodes in the system. The processor at the one or more other nodes locally processes the transaction and compares its results with the replicated steps and operations and/or indicia of the transaction that were received from one of the at least two nodes and executes one or more remediation actions when the result of the comparison indicates that the replicated steps and operations, and/or indicia of the replicated transactions do not match.
