Post-Quantum Cryptography Challenges for Crypto Exchanges
- Crypto exchanges like Binance and Coinbase rely on hierarchical deterministic wallets standardized under Bitcoin Improvement Proposal (BIP32).
- Project Eleven’s research suggests that BIP32 may not function with post-quantum signature schemes such as ML-DSA.
- The U.S. National Institute of Standards and Technology has finalized ML-DSA as part of its post-quantum cryptography program.
- Project Eleven, founded in 2024, is backed by Castle Island Ventures and Coinbase Ventures.
- Current systems could use hardware security modules or secure enclaves, but this adds complexity and risk.
Research indicates that if Bitcoin adopts ML-DSA without certain constructions, exchanges may lose the ability to generate new addresses from a public key alone, impacting their operational efficiency significantly.
Project Eleven has developed a prototype wallet using quantum-resistant techniques to maintain functionality similar to BIP32’s non-hardened key derivation, crucial for crypto infrastructure stability in a post-quantum world. (Source)
