What is the 2029 deadline for agent infrastructure?

Google's crypto team set 2029 as the migration cutoff for post-quantum crypto , driven by qubit estimates dropping to break ECC.

Will quantum computers break agent protocols like Visa TAP?

Yes—most use ECC (ES256, secp256k1), vulnerable to Shor's algorithm with ~10k-25k qubits, feasible by 2029.

Adopt hybrid signatures, prioritize behavioral trust over pure crypto, and design for modular upgrades—STARKs and lattice ZK are ready-ish.
