Ethereum Foundation invests $7.4 million in Q4 and is betting on security ten years down the line

The Ethereum Foundation has just announced its funding details for Q4 2025, and this time the scale is significant. The total grants awarded in the last quarter reached $7,385,528.84, equivalent to $74 million. These funds are allocated across 8 different ecological sectors. But more notably, behind this routine funding, the foundation is betting on something more long-term.

What is the $74 Million Ecosystem Support Doing

According to the latest news, Q4 funding covers the following main areas:

• Protocol growth and support
• Overall growth and support
• Developer experience and tools
• Execution layer
• Cryptography and zero-knowledge proofs
• Consensus layer
• Community and education
• Others

This distribution reflects the Ethereum Foundation’s strategic priorities: supporting the evolution of the core protocol (execution layer, consensus layer) while also focusing on developer experience and community building. Funding in cryptography indicates that security research remains a key focus.

Post-Quantum Security Becomes the Top Strategic Priority

But what is truly worth deeper exploration is that, alongside the Q4 funding announcement, the Ethereum Foundation has made a more aggressive decision: establishing a dedicated post-quantum security team.

According to related news, this team is led by cryptography engineer Thomas Coratger, with researcher Justin Drake participating. The foundation has invested $2 million in a prize program, including $1 million for the Poseidon Prize (used to strengthen hash functions in zero-knowledge proof systems) and $1 million for the Proximity Prize.

This is not an ordinary research project. The foundation explicitly lists post-quantum security as the highest strategic priority, aiming to complete Ethereum’s protective upgrades before quantum computers pose a real threat to existing cryptographic systems.

Why Prepare Now for Threats Decades Later

The idea that quantum computers could crack current encryption algorithms sounds like science fiction, but the foundation takes it very seriously. Justin Drake publicly states that the probability of cracking is about 20% before 2030. This is not a zero-risk scenario.

What is the core challenge of post-quantum security? The computational cost of quantum-resistant algorithms is enormous, which would significantly increase transaction fees. The foundation’s goal is to reduce the cost of post-quantum transactions by 83%, ensuring security without compromising user experience.

The Foundation’s True Considerations from Funding Strategies

Looking at these two initiatives together reveals a clear strategic mindset:

In the short term, supporting ecosystem development across various layers with $7.4 million in routine grants. In the long term, investing $2 million in post-quantum research to prepare for potential threats. This is not an either-or choice but a dual-track approach.

Interestingly, the post-quantum security research involves multiple technical directions such as LeanVM, zero-knowledge proofs, and the consensus layer—all of which are key areas in the Q4 funding. The foundation is using grants to support ecosystem developers in these areas while incentivizing cutting-edge research through prize programs.

Summary

This combination of strategies from the Ethereum Foundation demonstrates what: a mature ecosystem not only focuses on current growth but also prepares for future uncertainties. The $7.4 million supports the current ecosystem prosperity, while $2 million is invested in potential threats decades ahead. This balanced resource allocation exemplifies a long-term perspective.

For participants in the Ethereum ecosystem, this means the foundation is seriously considering the long-term security and sustainability of the ecosystem. The projects and researchers receiving funding are laying the groundwork for Ethereum’s future.
