Original Abstract Submitted

a system for enabling escrow-free, secure, and convenient atomic asset swaps between blockchains are provided. in detail, when any group of users reach an agreement on the content of cross-chain asset swap transactions, each participant creates an individual signature on the content of each transaction, employs a reversible signature aggregate function to produce an aggregate signature from all his/her individual signatures, and optionally generates a proof to prove the relationship between the aggregated signature and the transaction contents. sequentially, all the participants exchange these aggregated signatures and optional proofs. once a participant publishes one of his/her individual signature, the other parties can use both signatures—one from the sender and the other from the recipient—to construct a complete transaction. once a transaction is broadcast, its corresponding transactions are constructed, and broadcast. upon all transactions being confirmed by the blockchain nodes or miners, the asset swap between participants is completed.
