Abstract
In one embodiment, a computer-implemented method includes, using a transaction processor of a first computer, receiving a request from a second computer to verify a first transaction ledger in comparison to a second transaction ledger. The method includes converting the first transaction ledger and the second transaction ledger to a normalized data format. The method includes executing one or more cryptographic one-way hash algorithms over the first transaction ledger and the second transaction ledger to create and store in memory a first hash tree for the first transaction ledger and a second hash tree for the second transaction ledger. The method includes forming and transmitting to the second computer a response to the request based on a comparison of the first hash tree and the second hash tree, the response including a notification of inconsistency between the first transaction ledger and the second transaction ledger or identified discrepancies and updates.
