The Ethereum Foundation has taken a significant step toward long-term network security by establishing a dedicated post-quantum security team and committing new funding to cryptographic research. The move reflects growing concern that advances in quantum computing could eventually undermine today’s encryption standards.
The newly formed team will focus on preparing Ethereum for potential quantum computing threats, which could one day compromise widely used cryptographic algorithms. Foundation leadership has elevated post-quantum security to a top strategic priority, citing accelerating timelines and the need for proactive defenses rather than reactive fixes.
Coinbase said ” in an X post on Friday;
A key pillar of this effort is the development of lean, quantum-resistant infrastructure, including work on hash-based signature systems designed to remain secure even against powerful quantum machines. Multiple Ethereum client teams are already running post-quantum development networks, signaling that research is moving beyond theory into implementation.
To support this initiative, the foundation announced a $1 million Poseidon Prize aimed at strengthening a cryptographic hash function central to Ethereum’s zero-knowledge proof systems. This funding builds on an earlier $1 million research prize targeting broader post-quantum cryptography.
The announcement comes amid wider industry attention on quantum risks. Ethereum’s roadmap, which includes account abstraction and flexible upgrade paths, is viewed as better positioned for post-quantum migration than networks requiring more rigid consensus changes. As quantum research advances, Ethereum’s early investment highlights a long-term strategy to preserve security, decentralization, and network resilience.
