Replication code and measured artifacts for KeystrokeAuthChain: a keystroke-dynamics continuous-authentication Transformer evaluated on the public CMU Killourhy-Maxion dataset (EER 7.47%), coupled to an on-chain audit layer that anchors each authentication decision on the Ethereum Sepolia testnet for non-repudiation and third-party-verifiable auditing. Includes the recognition pipeline, paired baselines, significance tests, the audit smart contracts and gas measurements, and the real end-to-end anchoring run (10 genuine decisions, on-chain decisionHash verified 10/10). The CMU dataset is not redistributed here (see data/README.md inside the archive).
