Ethereum’s 2026 roadmap centers on two tracks: expanding rollup data capacity through blobs while pushing base-layer execution higher through gas limit changes.
Those gas limit changes depend on validators moving from re-executing blocks to verifying ZK execution proofs.
The first track is already anchored by Fusaka, which shipped Dec. 3, 2025.

Fusaka sets up PeerDAS plus blob parameter only (BPO) changes that can raise blob throughput in measured steps, according to ethereum.org.
The second track is less mechanized because it relies on draft EIPs, client implementation, and validator operations that have to stay within decentralization constraints, including bandwidth, block propagation, and proving market structure.
