\section{Conclusion}
|
|
|
|
|
|
We presented a comprehensive universal threshold signature framework addressing practical deployment challenges across 20+ blockchains. Our system integrates four core protocols (CMP, FROST, LSS, Doerner) with chain-specific adapters providing native support for diverse signature schemes (ECDSA, EdDSA, Schnorr, post-quantum Pulsar).
|
|
|
|
The LSS dynamic resharing protocol enables live membership changes without downtime or master key reconstruction, solving critical operational challenges for production systems. Performance benchmarks demonstrate sub-25ms signing latency with 100\% test coverage and Byzantine fault tolerance.

|
|
|
Production deployment secures billions in digital assets across enterprise custody, DeFi protocols, and cross-chain bridges, validating the framework's practical viability. Post-quantum Pulsar signatures provide quantum-resistant alternatives for long-term security.
|
|
|
|
Over four years of continuous development (February 2021 - August 2025, 800+ commits), we evolved from initial CMP/FROST implementation to a production-ready universal infrastructure. The framework's extensible architecture and comprehensive testing establish a foundation for next-generation threshold cryptography.
