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 three-phase migration strategy for transitioning production blockchain networks from classical to post-quantum cryptography. The migration must be gradual---a hard cutover risks breaking every wallet, validator, and application simultaneously. Phase 1 deploys hybrid signatures (classical ECDSA/BLS + post-quantum ML-DSA) where both must verify. Phase 2 makes the post-quantum signature primary with the classical signature as fallback. Phase 3 deprecates classical signatures entirely. We formalize the concept of \emph{crypto agility}: the ability to add, replace, or remove cryptographic algorithms without hard fork. We specify the key management requirements during transition, where validators maintain four key types simultaneously (EC secp256k1, BLS12-381, ML-DSA-65, Pulsar Module-LWE). We define backward compatibility rules ensuring old clients can verify classical signatures while new clients verify both. We provide concrete upgrade paths for existing validators and analyze the NIST standardization timeline (FIPS 203/204/205 published August 2024) as the basis for each phase trigger. The Lux network is currently in Phase 1 with triple-proof consensus providing hybrid classical/PQ security since genesis.
