Vitalik Buterin Maps Quantum Upgrade to Ethereum to Replace Core Cryptography

In brief

  • Buterin pointed out four Ethereum components that rely on cryptography vulnerable to quantum attacks.
  • The plan replaces BLS, KZG, and ECDSA with hash-based, lattice-based, or STARK-based systems.
  • Recursive aggregation aims to reduce high gas costs from quantum-safe signatures and proofs.

Ethereum co-founder Vitalik Buterin on Thursday called for a broad overhaul of the network’s cryptographic foundations, warning that advances in quantum computing could break core parts of the protocol, while…
