The Enterprise Ethereum Alliance hosted a private executive session at Microsoft’s New York offices to explore Ethereum’s upcoming Fusaka upgrade, featuring Trenton Van Epps from the Ethereum Foundation and Protocol Guild in conversation with Redwan Meslem, Executive Director of the EEA.
The discussion unpacked how Ethereum governance works, what the Fusaka upgrade delivers, and why these developments matter for enterprises building on Ethereum.
Understanding the Landscape
Redwan opened by explaining how the EEA and the Ethereum Foundation work in parallel.
The EEA is a member-based trade organization that promotes Ethereum adoption for enterprises and acts as a forum for collaboration.
The Ethereum Foundation (EF) leads research and the technical roadmap, coordinating hundreds of independent developers who maintain multiple Ethereum client implementations.
This client diversity, he noted, is what makes Ethereum highly resilient and keeps it running even if one client encounters an issue.
How Upgrades Happen
Trenton outlined how upgrades like Fusaka are developed and coordinated:
Improvements are proposed through Ethereum Improvement Proposals (EIPs) that anyone can review or contribute to.
Decisions are based on rough consensus, not formal voting, ensuring all perspectives are heard before features are bundled into an upgrade.
Around 200 core developers are supported through the Protocol Guild, which provides ongoing funding for contributors maintaining the network.
What Fusaka Delivers
Fusaka, scheduled for activation in December 2025, introduces several key updates aimed at scalability and network performance.
1. PeerDAS for rollups Peer Data Availability Sampling (PeerDAS) lets nodes verify data by sampling small portions rather than storing entire data sets. This reduces bandwidth needs and increases data capacity for Layer 2 rollups, leading to lower and more predictable transaction costs.
2. Progressive scaling Ethereum will raise blob and gas-limit parameters step-by-step after Fusaka goes live, allowing the network to monitor real-world performance before each increase. This cautious approach protects the stability of what Redwan described as a “$500 billion infrastructure.”
3. Improved cryptography and UX A new cryptographic precompile will support the same standard used by modern passkeys on iOS and Android. This opens the door for simpler wallet authentication and new enterprise-friendly user experiences.
Security and Resilience
Trenton emphasized that Ethereum’s rollup-centric roadmap preserves the ability for users to exit from Layer 2 networks back to mainnet even if a sequencer fails. This coupling between L2s and mainnet ensures strong security guarantees while scaling throughput.
Looking Ahead
The briefing closed with a preview of what comes next: continued research on faster finality, zero-knowledge EVMs, and future upgrades that further expand Ethereum’s capacity.
For enterprise builders, the core takeaway is that Fusaka strengthens Ethereum’s reliability, scalability, and usability, setting the stage for the next wave of real-world adoption.
