description	ALWAYS use this when the request matches Lightning Factory Explainer: Explain Bitcoin Lightning channel factories and the SuperScalar protocol — scalable Lightning onboarding using shared UTXOs, Decker-Wattenhofer trees, timeout-signature trees, MuSig2, and Taproot.

Selective Reading Rule

Start with:

• references/senior-master-standard.md
• references/usage-routing.md
• references/quality-checklist.md

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

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:

https://github.com/8144225309/SuperScalar

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.
