The Fusaka Files
A high-production limited series exploring Ethereum's strategic shift toward predictable, biannual engineering delivery — produced in collaboration with the Enterprise Ethereum Alliance.
Why The Fusaka Files started
Made for anyone who needs the upgrade story in context — not only changelog bullets, but how predictable shipping and the Fusaka era connect strategy, infrastructure, and real-world enterprise use.
- PurposeThe series was created to explain Ethereum's shift toward a predictable biannual engineering model and to situate the Fusaka upgrade inside that narrative — why cadence matters for clients, researchers, and coordination across the network.
- GoalBridge protocol milestones and roadmap choices to ecosystem readiness: scaling, resilience, credible neutrality, and how those themes land for builders and enterprises — not only for spec readers.
- Episodes bring in core contributors and ecosystem voices so you can follow how Fusaka-era work ties to PeerDAS, BPO, MEV resilience, and the road beyond — still in plain language you can share outside the implementers' chat.

Key Technical Topics
Each episode of The Fusaka Files ties directly to a foundational EIP shaping the next era of Ethereum. Here's what's covered in depth.
PeerDAS
Peer Data Availability Sampling scales the data capacity of the Ethereum network to support more blobs without exponentially increasing hardware requirements for nodes — a cornerstone for cheaper L2 transactions.
Gas Limit Cap
Introduces an upper bound on gas per transaction to mitigate worst-case execution scenarios and ensure continued stability and predictability of the execution layer under load.
Deterministic Proposer Lookahead
Improves how lookahead logic affects validator operations, increasing the predictability of the consensus layer for block proposers and enabling more stable MEV-related workflows.
secp256r1 Support
Integrates the "R flavor" cryptographic curve enabling native support for secure enclaves and passkeys in mobile devices and browsers — a fundamental building block for mass-market account abstraction.
Themes we explore
Connecting Fusaka changes to enterprise execution, resilience, and credible neutrality on the road to 2026.
Scaling & Enterprise Ethereum
PeerDAS, BPO, and a biannual roadmap cadence that makes engineering delivery more predictable for enterprises and institutions relying on Ethereum.
Resilience & Protocol Health
MEV-related proposals, safer execution patterns, and gas cap design that ensures the network holds up under pressure at scale.
Credible Neutrality
How Fusaka upgrades are coordinated across diverse stakeholders — so incentives stay aligned as the chain evolves toward a rollup-centric future.
Road to 2026: What Comes Next
Fusaka is a milestone in a longer narrative. Episodes trace the path to Verkle Trees and Statelessness — helping builders and operators plan ahead.
