A system, method and apparatus in which a client computer initiates and communicates a distributed ledger transaction, which transaction is labeled with a timestamp. A first hashing algorithm are applied to the transaction data and timestamp data to create a first hash value, and the first hash value is associated with the transaction data. When a second distributed ledger transaction is initiated, a second hashing algorithm is applied to the second transaction data to generate a second hash value, and a third hashing algorithm is applied to the to the first and second hash values to create a third hash value which is associated with the second transaction data. The procedure is implemented with each additional transaction data submission. The transaction data is processed in a first-in-first-out sequence based upon the hash values associated with the transaction data.
