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}
|
|
Digital securities have multi-decade lifetimes: a 30-year bond issued
|
|
today must remain unforgeable in 2056. Current blockchain infrastructure
|
|
relies on ECDSA (secp256k1) and Ed25519, both broken in polynomial time
|
|
by Shor's algorithm on a cryptographically relevant quantum computer
|
|
(CRQC). We present the post-quantum security architecture of the Lux
|
|
network, which deploys three NIST-standardized post-quantum algorithms
|
|
as native EVM precompiles: ML-KEM (FIPS~203) for key encapsulation,
|
|
ML-DSA (FIPS~204) for digital signatures, and SLH-DSA (FIPS~205) for
|
|
stateless hash-based signatures. The precompiles are activated at
|
|
genesis block~0, making post-quantum cryptography available from chain
|
|
launch rather than requiring a hard fork. We describe the hybrid
|
|
classical/post-quantum migration path: during the transition period,
|
|
transactions carry both an ECDSA signature and an ML-DSA signature;
|
|
the chain accepts the transaction if either signature verifies,
|
|
enabling gradual migration without breaking existing tooling. We prove
|
|
that the hybrid scheme achieves ``best of both worlds'' security:
|
|
it is unforgeable as long as \emph{either} the classical or the
|
|
post-quantum assumption holds. We give gas cost benchmarks for all
|
|
three algorithms at NIST security levels 2, 3, and~5, and explain
|
|
why securities infrastructure specifically---with its long asset
|
|
lifetimes and regulatory record-keeping requirements---must adopt
|
|
post-quantum cryptography before the quantum threat materializes.
