The most comprehensive technical analysis of NIST FIPS 203/204/205 post-quantum cryptography versus every major blockchain. Ed25519, secp256k1, ECDSA — none survive Shor’s algorithm. BMIC does.
Every classical blockchain — Bitcoin, Ethereum, Solana, XRP — relies on elliptic-curve cryptography (secp256k1 or ed25519). Shor’s algorithm, running on a sufficiently large quantum computer, recovers private keys from public keys in polynomial time. This is the “harvest now, decrypt later” threat: adversaries are already archiving signed transactions today, waiting for quantum hardware to mature.
BMIC implements NIST FIPS 203 (ML-KEM/Kyber), FIPS 204 (ML-DSA/Dilithium), and FIPS 205 (SLH-DSA) — the three post-quantum standards finalised by NIST in 2024. These are lattice-based and hash-based algorithms with no known quantum attack.
Each comparison page below provides a detailed technical breakdown for the specific cryptographic exposure of the given chain, covering: consensus key types, HNDL archive depth, validator/bridge key exposure, smart contract upgrade authority risks, and how BMIC’s ERC-4337 smart-account vault architecture mitigates each vector.
