Ethereum Maps Out A Post-Quantum Upgrade
The Ethereum Foundation has opened a public hub for its post-quantum work, outlining how execution, consensus, and data availability would all need to change before a usable quantum machine arrives.
The Ethereum Foundation has opened a public hub for its post-quantum security work, making clear that the network wants a migration path in place long before a usable quantum computer shows up. The new site, pq.ethereum.org, gathers the roadmap, research, specifications, code repositories, and FAQ for a project the Foundation says has been building in the background for years.
CoinDesk reports that more than 10 client teams are already shipping weekly devnets through what the Foundation calls PQ Interop. The plan reaches across Ethereum's stack. At the execution layer, the goal is to let users move toward quantum-safe signatures through account abstraction instead of forcing one sudden networkwide cutover. At the consensus layer, the current BLS validator scheme would give way to hash-based signatures, with zero-knowledge aggregation helping contain the cost of much larger proofs. The same push extends to blobs and data availability as well.
