Ethereum launches quantum-computing response unit… "Aiming to implement at the protocol level by 2029"

Ethereum developers have launched a dedicated organization to address threats from quantum computers.

According to Cointelegraph on the 24th (local time), developers affiliated with the Ethereum Foundation formed a “Post-Quantum” team and unveiled a related resource hub.

The team aims to integrate cryptographic systems that remain secure even in a quantum-computing environment into the Ethereum protocol, with a plan to push for deployment on the consensus layer by 2029. It will later consider expanding to the execution layer and beyond.

The prevailing view is that there is no immediate quantum-computing threat to blockchains at present. However, the explanation is that the network’s architecture requires lengthy development and verification for large-scale upgrades, making preemptive action necessary.

The development team said, “Transitioning a decentralized global protocol requires years of collaboration and engineering,” adding, “We need to start the work before the threat materializes.”

Quantum computers could potentially break existing cryptographic systems, raising industry-wide concerns over wallet security and private-key protection.

Accordingly, Ethereum developers are reviewing an approach that uses SNARK (zero-knowledge proof)-based signature technology to address both security and performance degradation at the same time.

The technology aims to counter quantum attacks while minimizing any decline in network performance.

The scope covers the consensus, execution and data layers, with an initial focus on protecting general-user wallets. It will later expand to key infrastructure wallets such as exchanges, bridges and custody providers.

The development team explained that “the biggest challenges are securely migrating hundreds of millions of accounts, preventing new vulnerabilities, maintaining performance, and ensuring collaboration across the entire ecosystem.”
