USING VIRTUAL BLOCKCHAIN PROTOCOLS TO IMPLEMENT A FAIR ELECTRONIC EXCHANGE

摘要

Methods for a virtual blockchain protocol include generating a public key and a private key for transmitting a message from a sender to a recipient. The sender encrypts the message using the public key and a cryptographic key of the recipient to generate a first data package. The sender signs a hash function of the first data package using a cryptographic key of the sender to generate a third data package. The sender transmits the first data package and the third data package to the recipient. The sender receives a signed version of the third data package signed using the cryptographic key of the recipient. The sender determines that the signed version of the third data package has been posted to a blockchain. The sender posts the private key to the blockchain.
