Abstract: Methods and systems described in this disclosure electronically notarize a document. The system can receive biometric information from a user, extract characteristics from the biometric information, and compare the characteristics of the biometric information with previously stored characteristics of the user's biometric information. When the characteristics of the biometric information match the previously stored characteristics to a threshold, the system can create an identity of the user using the characteristics of the biometric information. The system can send a document to the user for cryptographic signature and receive an indication that the document has been signed. The cryptographic signature can be generated with a digest of the document, the identity, and a cryptographic key associated with the user. The system can inspect the digest of the document, the cryptographic key, and the identity associated with the document to verify authenticity of the document and the identity of the user.

Abstract: A system includes at least one processor and at least one memory communicatively coupled to the at least one processor, where the at least one memory stores instructions. When executed by the at least one processor, the instructions are configured to receive death certificate information from a node of a distributed ledger system, determine, a record to be updated based at least in part on the death certificate information, and update the record. The death certificate information and the record are associated with an individual.

Abstract: Systems and methods for performing netting of business-to-business payments for settlement of running balances between parties are provided. To that end, blockchain infrastructures allow smart contracts that may be suitable for subrogation and netting operations, and the smart contracts that facilitate the operations. Application-programming interfaces (APIs) are provided that may be used to interact with the smart contracts.
