Patent 11949788 was granted and assigned to Codenotary on April, 2024 by the United States Patent and Trademark Office.
Disclosed herein are computer-implemented methods of, and computer systems for, constructing dual cryptographic proofs for transactions where transaction data is stored in a cryptographically-linked data file and in an incremental hash tree, where a dual cryptographic proof includes linear cryptographic proof data from the cryptographically-linked transaction file and binary cryptographic proof data from the incremental hash tree. The transaction may include one or more key-value pairs.
