This skill provides comprehensive technical guidance for building and auditing Lightning Network channel factories and Layer 2 scaling infrastructure. It focuses on implementing multi-party channels without requiring Bitcoin soft forks, leveraging Decker-Wattenhofer invalidation trees and MuSig2 key aggregation. Developers can use this skill to integrate production-grade features like watchtower breach detection, HTLC/PTLC forwarding, and encrypted Noise NK transport protocols, drawing from high-performance reference implementations like the SuperScalar project.
