The abstract contains an overview of the patent disclosure:

A method and system are provided to support a decentralized distributed ledger in which transactions are recorded by parties to the transactions without the use of a blockchain. A distributed ledger system provides a protocol framework that supports the development of protocol flows. A protocol flow is computer code that controls the performance of a transaction by the party or parties to the transaction. Protocol flows can be developed for different types of transactions. The distributed ledger system allows transactions to be proposed, accepted, and notarized by a notary and stored without the use of a blockchain ledger. The distributed ledger system can avoid the expense of the computational and storage resources needed to redundantly verify a transaction and store evidence on the many nodes of a blockchain distributed ledger.
