Ethereum Sets Quantum-Resistant Target for 2029 Amid Growing Cryptographic Threats

The Ethereum Foundation has outlined its strategic priorities through 2029, with quantum resistance for Ethereum's Layer 1 (L1) blockchain as its primary objective.

According to an official blog post published on September 7, achieving post-quantum security across execution, consensus, and data layers by December 2029 is the cluster's 'north star.'

This commitment aligns Ethereum with migration targets set by tech giants like Google, Cloudflare, and Microsoft, all of which have flagged the mid-2030s as a critical window for post-quantum cryptography adoption in preparation for 'Q-day', the point when quantum computers could break conventional cryptography.

The upcoming Hegotá fork, expected to commence implementation in late Q4 2026, will be the first major milestone on Ethereum's path to quantum preparedness. It will introduce foundational upgrades, such as EIP-7805's fork-choice enforced inclusion lists (FOCIL) for censorship resistance and EIP-8141's new transaction model, 'Frames.'

The Hegotá fork also aims to provide native support for private transactions on Ethereum L1 through privacy-focused updates like EIP-8250 (Keyed Nonces) and EIP-8272 (Recent Roots).
