Ethereum Targets Full Post-Quantum Security for Its L1 by 2029

Ethereum‘s development roadmap is targeting full post-quantum security for its base layer by 2029, with initial upgrades focused on account abstraction and censorship resistance planned for the upcoming Hegotá hard fork.

The long-term goal is to make the Ethereum Layer 1 protocol resistant to potential attacks from future quantum computers, which could theoretically break current cryptographic standards. This multi-year initiative will begin with foundational changes in the Hegotá upgrade.

These early steps are expected to enhance account abstraction capabilities and bolster the network’s censorship resistance. The broader 2029 target underscores the extended timeline required for such a fundamental cryptographic overhaul of a major blockchain.

Ethereum’s Quantum-Resistant Roadmap

The move to post-quantum cryptography is a proactive measure against a future threat, as large-scale quantum computers capable of breaking today’s encryption are not yet a reality. The planned upgrades represent a significant shift in Ethereum’s core security model.
