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.

\begin{abstract}
|

We present \textbf{M-Chain}, a purpose-built blockchain for decentralized multi-party computation (MPC) custody of cross-chain assets. M-Chain eliminates single points of failure in traditional bridge architectures by implementing on-chain threshold signature coordination, autonomous slashing for non-performing signers, and quantum-resistant dual-signature protocols. The system supports multiple threshold schemes (CGG21 for ECDSA, MuSig2 for Bitcoin Taproot, FROST for EdDSA, and Corona for post-quantum security) with sub-200ms signature generation latency. M-Chain introduces the \textbf{SwapSigTx} transaction type, providing cryptographic proof that a threshold quorum has authorized a cross-chain transfer, replacing centralized swap databases with auditable on-chain logic. Economic incentives align validator behavior through per-signature rewards and time-based slashing penalties. We demonstrate custody of Bitcoin, Ethereum, and XRPL assets with $>$99.9\% uptime and zero security incidents across 10,000+ daily swaps processing \$20M+ in volume.
