Bylines, paper authorship, correspondence addresses and the founder blurb under each post named an individual. They name the organisation that published the work instead: the brand on posts and pages, the research byline on papers, and research@ in place of a personal address. Both are what these repositories already used elsewhere — nothing new was coined. Co-authors are untouched. Where a paper named someone else alongside, they stay named; only the one byline changed. Bibliography entries, running heads, PDF metadata and affiliations move with it, so a citation still resolves to whoever the cited paper names. Sample and fixture data uses the placeholder name these tests already use elsewhere, so no assertion changed meaning.

We present a comprehensive universal threshold signature framework supporting 20+ blockchains through unified cryptographic protocols with post-quantum security. Our system integrates four core protocols---CMP (ECDSA), FROST (Schnorr/EdDSA), LSS (dynamic resharing), and Doerner (2-party optimization)---with chain-specific adapters providing native support for XRPL, Ethereum, Bitcoin, Solana, Cardano, TON, and 14 additional networks. The framework achieves sub-25ms signing latency, 100\% test coverage, and Byzantine fault tolerance up to $t-1$ malicious parties. We introduce the LSS protocol for live membership changes without downtime, enabling practical deployment in production custody systems. Post-quantum security via Pulsar lattice-based signatures provides 128/192/256-bit security levels as quantum-resistant alternatives. Performance benchmarks demonstrate 12-82ms key generation and 8-40ms signing across threshold configurations from 3-of-5 to 10-of-15. The system is production-deployed securing billions in digital assets across enterprise custody solutions, DeFi protocols, and cross-chain bridges. This work represents over four years of continuous development (February 2021 - August 2025) with 800+ commits.
