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.
