Abstract
A digital currency intra-chain and cross-chain off-chain swap method based on trusted hardware. An initiator sends a swap message containing a public-private key pair to be swapped by a initiator to a responder, and deletes the public-private key pair to be swapped by the initiator; after receiving the swap message, the responder saves and locks the public-private key pair to be swapped by the initiator, locks the public-private key pair to be swapped by the responder, and sends a response message containing the public-private key pair to the initiator; after receiving the response message, the initiator saves the public-private key pair to be swapped by the responder and sends a confirmation message to the responder; after receiving the confirmation message, the responder deletes the public-private key pair to be swapped by the responder and unlocks the public-private key pair to be swapped by the initiator to complete the swap.
