Research

The leaderboard is only useful if the underlying cryptography is stated plainly. These notes are the short version.

01

Why ECC fails under Shor

ECDSA, EdDSA, secp256k1, and Ed25519 all reduce to the elliptic-curve discrete log. A cryptographically relevant quantum computer does not need to “hash harder.”

02

Resource estimates and Q-Day

Google’s 2026 ECDLP estimates, Project Eleven demos, and why the remaining uncertainty is calendar, not category.

03

What “good” looks like

Hybrid migration, native PQC, key rotation, and why “we are researching it” is not a posture change.
