アトミック・スワップ (Atomic Swap)
仲介者なしでの暗号資産の直接交換。
Network Benefits: 1. Sovereignty: Users retain full control of private keys. 2. Interoperability: Bridges isolated blockchain 'silos'. 3. Security: No single point of failure (unlike CEXs). Challenges: 1. Complexity for end-users. 2. Time delays due to block confirmations on multiple chains.

Think of it as a global vending machine system where you can put in a [Bitcoin](/ja/terms/bitcoin) and get out Litecoins immediately, without any person in the middle holding your money. If the machine breaks or the other person walks away, you just get your Bitcoin back automatically.
🤓 Expert Deep Dive
The plural 'Atomic Swaps' refers to the broader implementation of this technology in DEX protocols and Layer-2 networks. A major technical hurdle for widespread adoption is the 'Liquidity Problem'—unlike an Order Book or AMM, an atomic swap requires a specific counterparty for every trade. Advanced versions like 'Submarine Swaps' enable bridging between the Bitcoin mainnet and the Lightning Network, while emerging 'Adaptor Signatures' aim to replace HTLCs to improve privacy and reduce on-chain footprint by making swaps look like standard transactions.
