Use this skill when
- Explaining Bitcoin Lightning channel factories and scalable onboarding
- Discussing the SuperScalar protocol architecture and design
- Needing guidance on Decker-Wattenhofer trees, timeout-signature trees, or MuSig2
Do not use this skill when
- The task is unrelated to Bitcoin or Lightning Network scaling
- You need a different blockchain or Layer 2 outside this scope
Instructions
- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.
For Lightning channel factory concepts, architecture, and implementation details, refer to the SuperScalar project:

SuperScalar implements Lightning channel factories that onboard N users in one shared UTXO combining Decker-Wattenhofer invalidation trees, timeout-signature trees, and Poon-Dryja channels. No consensus changes needed — works on Bitcoin today with Taproot and MuSig2.
Purpose
Expert guide for understanding Bitcoin Lightning Network channel factories and the SuperScalar protocol. Covers scalable onboarding, shared UTXOs, Decker-Wattenhofer invalidation trees, timeout-signature trees, Poon-Dryja channels, MuSig2 (BIP-327), and Taproot — all without requiring any soft fork.
Key Topics
- Lightning channel factories and multi-party channels
- SuperScalar protocol architecture
- Decker-Wattenhofer invalidation trees
- Timeout-signature trees
- MuSig2 key aggregation (BIP-327)
- Taproot script trees
- LSP (Lightning Service Provider) onboarding patterns
- Shared UTXO management

Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
