Blockchain auditing system and method

A method comprising:

• calculating and storing, by a microprocessor, a copy of a first hash, wherein the first hash is calculated against a blockchain in a distributed ledger and wherein the first hash is stored separately from the distributed ledger;
• calculating and storing, by the microprocessor, a second hash, wherein the second hash is calculated against the blockchain in the distributed ledger and wherein the second hash is stored separately from the distributed ledger;
• identifying, by the microprocessor, an event associated with the blockchain in the distributed ledger;
• and
• in response identifying the event associated with the blockchain in the distributed ledger, identifying a compromise of the blockchain in the distributed ledger based at least one of the first hash and the second hash.

A non-transitory computer-readable data storage medium storing instructions executable by a processor to:

• calculate and store a copy of a first hash, wherein the first hash is calculated against a blockchain in a distributed ledger and wherein the first hash is stored separately from the distributed ledger;
• calculate and store a second hash, wherein the second hash is calculated against the blockchain in the distributed ledger and wherein the second hash is stored separately from the distributed ledger;
• identify an event associated with the blockchain in the distributed ledger;
• and
• in response identifying the event associated with the blockchain in the distributed ledger, identify a compromise of the blockchain in the distributed ledger based at least one of the first hash and the second hash.
