Ethereum's 2026 roadmap leans on ZK-proof validators amid gas limit and blob scaling push
Ethereum's 2026 plan is built around two parallel efforts: increasing rollup data capacity with blobs via Fusaka, which activated on Dec. 3, 2025, and lifting base-layer throughput through higher gas limits. That execution-side path relies on validators shifting from full block re-execution to verifying ZK execution proofs, supported by proposals such as PeerDAS, ePBS, BALs, and broader gas repricing. The roadmap introduces new liveness and decentralization risks tied to proving markets, bandwidth limits, and validator operations as upgrades like Glamsterdam and Hegota move through 2026 timelines.
