Ethereum proposes a roadmap to address the threat of quantum computing

ChainCatcher reports that, according to CoinDesk, Ethereum co-founder Vitalik Buterin has released a long-term roadmap proposing to address potential future quantum computing threats to network security by replacing signature and data schemes.

The roadmap indicates that Ethereum’s current consensus validator signatures (BLS), data availability schemes (relying on KZG commitments), daily wallet transaction signatures, and some zero-knowledge proofs are vulnerable to quantum attacks. Buterin suggests shifting validators to more quantum-resistant hash signatures and, with the core proposal EIP-8141, paving the way for account signature algorithm upgrades and “Validation Frames.” This approach aims to support quantum-secure signatures and proofs while reducing on-chain verification costs.
