PANews reported on February 27 that Ethereum co-founder Vitalik Buterin released a long-term roadmap outlining plans to address potential future threats to network security posed by quantum computing. 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 recommends transitioning validators to more quantum-resistant hash signatures and, centered around proposal EIP-8141, paving the way for account signature algorithm upgrades and “Validation Frames.” This approach aims to support quantum-safe signatures and proofs while reducing on-chain verification costs.
