lightning-factory-explainer

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.

The declared community implementation at 8144225309/SuperScalar returned HTTP 404 on 2026-10-14. Do not treat it as a verified production implementation, funded-mainnet deployment, 400-test suite or audited watchtower. The original SuperScalar proposal is a protocol source, not proof that a similarly named repository implements it correctly.

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

Explain Bitcoin Lightning channel factories and scalable onboarding.

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.

Review evidence

Distinguish proposal properties from a specific implementation revision. Trace funding ownership, required signers, offline/liveness assumptions, timelock ordering, old-state invalidation, recovery artifacts, fee/bump behavior and unilateral exit under congestion. Define what N measures before stating complexity. Verify HTLC/PTLC and watchtower compatibility with actual protocol versions and test vectors; a claim of no consensus change does not establish deployability or safety. Use an isolated regtest fixture; signing, funding or broadcasting with real funds needs separate explicit authorization.
