Post-Quantum Signatures, Part 3: Inside FIPS 205 Through Quranium’s SLH-DSA Adoption

XMSS organizes one-time signature keys into Merkle trees and hyper-trees, a practical post-quantum signature scheme with compact proofs and fast verification, at the cost of strict state management.

Trail of Bits released constant-time pure Go implementations of the post-quantum signatures ML-DSA (FIPS-204) and SLH-DSA (FIPS-205), avoiding division and branch timing leaks like KyberSlash.

CertiK joined LF Decentralized Trust, the Linux Foundation's enterprise blockchain community, to bring security expertise into shared open-source infrastructure as global regulation tightens.

CertiK's US policy head reports crypto momentum shifting from stalled legislation to regulators: SEC, CFTC and OCC are advancing market structure and stablecoin rules, with security as the foundation.

DGrid routes requests across 200+ AI models using onchain identities, x402 payments, and Proof of Quality ratings. By July 2026, 96 models had multiple provider routes enabling failover.

CertiK open-sourced four AI agent skills that plug its blockchain security intelligence into Claude Code, Codex, and Cursor, letting agents query wallet risk, AML screening, and EVM transaction forensics natively.
