Classification: CPC H | IPC H

Claim 19:
20. A computer system for generating cryptographic proofs, comprising:
a non-transitory data store comprising a cryptographically-linked transaction file comprising a plurality of cryptographically-linked transaction records and an incremental hash tree comprising a plurality of leaves, wherein each leaf corresponds to a different cryptographically-linked transaction record in the cryptographically-linked transaction file; and
a computer system operatively coupled to a communication channel and the non-transitory data store, wherein the computer system is configured with executable instructions that, when executed by a processor, cause the computer system to:
receive over the communications channel a first cryptographic proof request pertaining to a subject transaction that has been stored in a subject transaction record in the cryptographically-linked transaction data file;
generate first cryptographic proof data pertaining to the subject transaction, wherein the first cryptographic proof data comprises binary cryptographic proof data from the incremental hash tree and linear cryptographic proof data; and
transmit the first cryptographic proof data over the communications channel in response to the cryptographic proof request.
