Flashback: Sept 22, 2017, @SatoshiLite and @JStefanop1 successfully made the first cross-chain atomic swap between Litecoin and Bitcoin. Atomic swaps, also known as cross-chain atomic swaps, enable the peer-to-peer exchange of cryptocurrencies operating on different blockchains without a centralized intermediary. The term "atomic" comes from atomicity, a database principle ensuring that a transaction is indivisible. Atomic swaps are powered by Hashed Timelock Contracts (HTLCs). An HTLC is a smart contract that requires both parties to meet specific cryptographic conditions within a set timeframe to execute a transaction. It has two key components: a hashlock and a timelock. A hashlock secures the deposited cryptocurrency until both parties provide cryptographic proof that they have fulfilled their side of the agreement. LTC ⚡️
