Vitalik Buterin on Quantum Computing and Ethereum Security

boss

Key takeaways Buterin sees a nontrivial 20% chance that quantum computers could break current cryptography before 2030, and he argues that Ethereum should begin preparing for that possibility. A key risk involves ECDSA. Once a public key is visible onchain, a future quantum computer could, in theory, use it to recover the corresponding private key. Buterinโ€™s quantum emergency plan involves rolling back blocks, freezing EOAs and moving funds into quantum-resistant smart contract wallets. Mitigation means smart contract wallets, NIST-approved post-quantum signatures and crypto-agile infrastructure that can swap schemes without chaos.…

So parallel execution remains a vague ambition rather than a feature of most Ethereum L2s. Eclipse takes a different path. It brings the Solana Virtual Machine into an Ethereum-anchored environment and restructures the rollup stack around it. The latest report by Cointelegraph Research examines how this design emerged, the problems it solves and what questions it raises for the broader layer-2 ecosystem. It highlights where Eclipse diverges from existing rollups…
