Ethereum Updates in 2026: From Fusaka to Glamsterdam

Ethereum closed 2025 on a strong technical note and is carrying that momentum into 2026. After successfully completing both the Pectra and Fusaka upgrades last year, the next wave of Ethereum updates is now the central focus for developers, validators, and investors watching the protocol evolve in real time.

Fusaka Set the Stage for What Comes Next

The Fusaka hard fork activated on December 3, 2025, combining the Fulu consensus layer improvements with the Osaka execution layer changes. Among the most significant Ethereum updates in that cycle was the deployment of PeerDAS, which expanded data blob capacity from 6 to 48 per block, a major leap for Layer-2 rollup efficiency. The block gas limit was also raised from 45 million to 150 million, substantially increasing the number of transactions Ethereum can pack into each block. A per-transaction gas cap of 16.7 million was introduced to harden the network against denial-of-service attacks.

Together, these changes laid the infrastructure groundwork for what the 2026 upgrades are building on.

Glamsterdam Targets Speed, Scalability, and ZK Verification

The most anticipated of the upcoming Ethereum updates is Glamsterdam, planned for mid-2026. It combines the Glam consensus layer changes with the Amsterdam execution layer improvements. The upgrade targets three core areas:

• Parallel transaction processing to eliminate single-lane bottlenecks
• A gas limit increase from the current 60 million to potentially 200 to 300 million per block
• Native ZK proof verification at Layer 1, reducing computation costs for rollups and cross-chain bridges

With these improvements, Ethereum L1 could approach 10,000 transactions per second, while expanded blob capacity on L2 networks pushes those ecosystems significantly higher.

Heze-Bogota and the Longer Roadmap

Later in 2026, the Heze-Bogota upgrade is expected to deepen the network's privacy and security capabilities. Full native account abstraction via EIP-7701 is also planned for the second half of 2026 under the Hegota specification, making smart account behavior the default for all new accounts rather than an opt-in feature.

These consecutive Ethereum updates reflect a tightly packed development schedule. For traders and investors, each upgrade directly affects gas economics, ETH burn rates, staking dynamics, and Layer-2 activity.
