The method includes modifying at least one of the one or more variables included in the data file, generating a new hash value via application of one or more hashing algorithms to the modified data file, and generating a new transaction value based on at least the generated new hash value and the specific transaction hash. The method includes digitally signing the generated new transaction value, and electronically transmitting the signed new transaction value.
