  "map_content": "- Lightning payments themselves are not on-chain \u201cScript transactions.\u201d They\u2019re off-chain balance updates enforced by a set of pre-signed Bitcoin transactions.\n- Script is used under the hood to secure channels and HTLCs: channel funding (2-of-2 multisig), commitment transactions (to_local/to_remote with timelocks), HTLC outputs (hashlock + timelock), and anchor outputs for fee bumping.\n- If a channel force-closes or an HTLC times out/succeeds on-chain, those enforcement transactions are standard Bitcoin Script spends. But you can\u2019t attach arbitrary Bitcoin Script conditions to an LN payment like you would in a custom on-chain script.\n- With Taproot/Tapscript, the ecosystem is moving toward PTLCs and \u201cscriptless scripts\u201d (using adaptor signatures), which expand what\u2019s possible off-chain\u2014but this still doesn\u2019t mean arbitrary Script programs are carried over LN payments. Some advanced constructs (e.g., DLCs) can integrate with LN in research/prototypes, but broad, arbitrary scripting over LN is not supported today.",
