Using Virtual Blockchain Protocols to Implement Fair Electronic Exchanges

摘要

Methods for a virtual blockchain protocol include generating a public key and a private key to send a message from a sender to a recipient. The sender encrypts the message using the public key and the recipient''s encryption key to generate the first data payload. The sender signs the hash function of the first data payload using the sender''s cryptographic key to generate the second data payload. The sender sends the first data payload and the second data payload to the recipient. The sender receives a signed version of the second data payload that is signed using the cryptographic key of the recipient. The sender determines that the signed version of the second data payload has been sent to the blockchain. The sender sends the private key to the blockchain.
