atomic swap

Atomic swaps use cryptographic hash locks to exchange assets between two chains without trusting an intermediary.原子交换使用密码学哈希锁在两条链之间交换资产，而无需信任中介。

Atomic swaps were one of the earliest trustless cross-chain mechanisms, though they require both parties to be online.原子交换是最早的无需信任的跨链机制之一，尽管它们要求双方都保持在线。
