Post-Quantum Risk to Crypto: Google, BlackRock, MPC Custody, and What Breaks First
Is MPC custody post-quantum safe? No. This episode reviews 15 institutional MPC custody providers including Fireblocks, Copper, BitGo, Anchorage Digital, Cobo, Dfns, Fordefi, Zodia, Qredo, Taurus, and Ripple Custody. Collectively: $10T+ in digital assets, 550M+ wallets, $50B+ monthly volume. Zero are post-quantum safe end-to-end. MPC secures how the signature is produced. It does not change the classical signature (ECDSA, Ed25519) the blockchain verifies.
Post-Quantum Exposure Map 2026: 20+ named institutions, 30+ tokenized products, 11 chains. BlackRock, JPMorgan, Circle, Goldman, Franklin, WisdomTree, and others mapped to specific chain and signature exposure.
