。在哈希时间锁合约可能存在的区块链中,已经部署了原子交换,但是当其中一个区块链没有这种能力时,它就变成了一个挑战。该协议描述了如何在比特币和门罗币之间实现原子交换,每条链上有两个交易,而无需信任任何中央机构、服务器或其他交换参与者。我们建议在两个参与者之间进行交换,一个持有比特币,另一个持有门罗币,当双方都遵循协议时,他们的资金在任何时候都没有风险。该协议不需要门罗币端的时间锁,也不需要脚本功能,但需要两个离散对数相等的知识证明,跨越edward25519和secp256k1组,以及ECDSA一次性VES。
. In blockchains where hashed timelock contracts are possible atomic swaps are already deployed, but when one of the blockchains doesn’t have this capability it becomes a challenge. This protocol describes how to achieve atomic swaps between Bitcoin and Monero with two transactions per chain without trusting any central authority, servers, nor the other swap participant. We propose a swap between two participants, one holding bitcoin and the other monero, in which when both follow the protocol their funds are not at risk at any moment. The protocol does not require timelocks on the Monero side nor script capabilities but does require two proofs of knowledge of equal discrete logarithm across the edward25519 and the secp256k1 groups and ECDSA one-time VES.
