  • Publication number: 20190229921
    Abstract: This invention is in the field of private cryptographic transactions and discloses a method to create completely private “multi-signature” transactions using a private or “zero knowledge” proving system. The method includes multiple provers, each of which create one or more proofs with completely private hidden inputs. The proofs may require that a private value must be the same in more than one proof. The invention discloses a method of ensuring this by encrypting the private input and using this as a public input to the proofs.

  • Publication number: 20180331832
    Abstract: This invention is an improved system for processing transactions with a cryptographic currency. The system uses a blockchain protocol as a public record of transactions to ensure only valid tokens can be used as transaction inputs, and that they can be used only once. Witnesses assemble transactions into a blockchain. Once enough witnesses confirm a block, it becomes a permanent and indelible part of the blockchain.
