The huge US-based financial institution, JPMorgan Chase is seeking a patent on a system that would used distributed ledgers, a blockchain system, to facilitate and reconcile financial transactions.
 Distributed ledgers, such as Blockchain, provide a unique system for recording transactions and storing data. In general, distributed ledgers hold a log of transactions (events) that may be replicated across a public or private distributed network. Cryptography and digital signatures may be used to determine valid parties and transactions such that all parties/observers agree on the order and state of the ledger in real-time without having to rely on a trusted third party to hold the true "golden copy." The distributed ledger thus provides a practically immutable, verifiably true audit trail.
"In one embodiment, a method for processing network payments using a distributed ledger may include: (1) a payment originator initiating a payment instruction to a payment beneficiary; (2) a payment originator bank posting and committing the payment instruction to a distributed ledger on a peer-to-peer network; (3) the payment beneficiary bank posting and committing the payment instruction to the distributed ledger on a peer-to-peer network; and (4) the payment originator bank validating and processing the payment through a payment originator bank internal system and debiting an originator account."
