U.S. Patent 11036872 was awarded to SAP SE on June 15, 2021 and is entitled “Privacy-preserving sum-based consistency checks for blockchains.” The first named inventor is Axel Schroepfer of Borthen, . The abstract contains an overview of the patent disclosure:

A blockchain service receives a first request to insert a first value associated with a transaction into a blockchain. In response, the blockchain service calls a commitment service to obtain a commitment based on the first value. The blockchain service then inserts the commitment into the blockchain at a block associated with the transaction. When the blockchain service subsequently receives a second request to confirm whether a second value matches the first value, it can obtain the commitment from the blockchain. This obtained commitment is then passed to the commitment service along with the second value. The blockchain service then receives a confirmation from the commitment service whether the first value matches the second value. The blockchain service can provide a reply to the second request encapsulating the confirmation. Other variations are provided in which residual amount values can be confirmed. Related apparatus, systems, techniques and articles are also described. Link to Full Patent
