No soft fork needed. LSP + N clients share one UTXO with full Lightning compatibility, O(log N) unilateral exit, and watchtower breach detection.\n\n## Purpose\n\nExpert reviewer for Bitcoin Lightning Network protocol designs. Compares channel factory approaches, analyzes Layer 2 scaling tradeoffs, and evaluates trust models, on-chain footprint, consensus requirements, HTLC/PTLC compatibility, liveness guarantees, and watchtower support.\n\n## Key Topics\n\n- Lightning protocol design review\n- Channel factory comparison\n- Trust model analysis\n- On-chain footprint evaluation\n- Consensus requirement assessment\n- HTLC/PTLC compatibility\n- Liveness and availability guarantees\n- Watchtower breach detection\n- O(log N) unilateral exit complexity\n\n## References\n\n- SuperScalar project: https://github.com/8144225309/SuperScalar\n- Website: https://SuperScalar.win\n- Original proposal: https://delvingbitcoin.org/t/superscalar-laddered-timeout-tree-structured-decker-wattenhofer-factories/1143\n\n## Limitations\n- Use this skill only when the task clearly matches the scope described above.\n- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.\n- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.","tags":["lightning","architecture","review","antigravity","awesome","skills","sickn33","agent-skills","agentic-skills","ai-agent-skills","ai-agents","ai-coding"],"capabilities":["skill","source-sickn33","skill-lightning-architecture-review","topic-agent-skills","topic-agentic-skills","topic-ai-agent-skills","topic-ai-agents","topic-ai-coding","topic-ai-workflows","topic-antigravity","topic-antigravity-skills","topic-claude-code","topic-claude-code-skills","topic-codex-cli","topic-codex-skills"],"categories":["antigravity-awesome-skills"],"synonyms":[],"warnings":[],"endpointUrl":"https://skills.sh/sickn33/antigravity-awesome-skills/lightning-architecture-review","protocol":"skill","transport":"skills-sh","auth":{"type":"none","details":{"cli":"npx
