TechFlow news: On February 27, according to CoinDesk, Ethereum co-founder Vitalik Buterin proposed a roadmap to protect blockchains against the long-term risks posed by quantum computing. This announcement follows the Ethereum Foundation’s recent establishment of a dedicated post-quantum research team.
Buterin identified four key areas of vulnerability on X: validator signatures, Ethereum’s data availability system, everyday wallet signatures, and zero-knowledge proofs used by applications and Layer 2 networks.
The roadmap includes replacing validators’ current BLS digital signatures with “hash-based” signatures to resist quantum attacks; upgrading Ethereum’s KZG commitment mechanism—used to verify and store transaction data; enhancing wallet flexibility via the planned EIP-8141 upgrade, enabling accounts to switch to quantum-resistant signature schemes; and leveraging “verification framework” technology to bundle multiple signatures and proofs into a single composite proof, preserving cost efficiency.
