Ethereum Roadmap

Overview

The Ethereum roadmap is an evolving plan for protocol upgrades: changes to the consensus and execution layers that run Ethereum. It is not a promise that every proposal will ship on a fixed date, and it is not the roadmap for every independent Layer 2 network. As of October 2026, Ethereum.org lists the Glamsterdam upgrade for Q4 2026, with no confirmed mainnet date, and Hegotá for 2027.

The public timeline records major upgrades from The Merge through Pectra and Fusaka, which shipped in 2025. Current work aims to increase Ethereum’s capacity while keeping the network verifiable by a broad set of operators, improving how applications interact with it, and strengthening security and censorship resistance.

How to read the roadmap

Roadmap pages combine completed upgrades, work in testing, and longer-range goals. A listed feature can change as client teams test it and researchers refine designs. The best way to understand a proposed change is to separate its intended benefit from the conditions it still has to meet: implementation across clients, testing, security review, and a finalized activation schedule.

Ethereum scaling also has more than one layer. The base chain can improve execution capacity and data availability for rollups, while each Layer 2 has its own contracts, operators, upgrade process, and failure assumptions. A roadmap milestone does not automatically make every rollup decentralized or give every rollup the same security guarantees.

What Ethereum is prioritizing

The Ethereum Foundation’s 2026 protocol update groups work into three broad priorities. These are organizing themes for development, not a guarantee that each proposed feature will appear in one particular fork.

  • Scale: Increase Layer 1 capacity and continue scaling the data space used by rollups, while tracking the operational costs of running a node.
  • Improve user experience: Make accounts and applications easier to use, including work on native account abstraction and cross-Layer 2 interoperability.
  • Harden the Layer 1: Improve security, censorship resistance, and network resilience as the protocol grows more capable.

Glamsterdam: the next major upgrade

Glamsterdam is the next major upgrade shown on the current Ethereum roadmap. Its main features include enshrined proposer-builder separation (ePBS) and block-level access lists (BALs). The Sepolia test network activated the upgrade on October 6, 2026. The Ethereum Foundation’s announcement said Hoodi and mainnet dates had not yet been decided, so the Q4 2026 label is a target rather than a scheduled launch.

Today, specialized builders may assemble blocks while validators choose and propose them, often with help from off-protocol relay software. ePBS aims to bring that separation into Ethereum’s protocol. It can reduce reliance on trusted relays and give the network more room to propagate block data, but it cannot by itself eliminate MEV or guarantee that block building becomes decentralized.

Block-level access lists describe which parts of Ethereum’s state a block will touch. Knowing those dependencies in advance can make parallel execution and data access easier to implement. These changes are intended to support higher Layer 1 capacity. Their practical effects still depend on implementation, testing, and the hardware and network costs they create.

Hegotá and longer-term work

The current roadmap places Hegotá after Glamsterdam and lists it for 2027. One proposed focus is fork-choice enforced inclusion lists (FOCIL), a design in which validators can help require that valid transactions are included even when a block builder would prefer to omit them. This could strengthen censorship resistance, but its design and eventual scope remain subject to protocol development and testing.

Ethereum’s longer-term work also includes scaling rollup data, making account interactions more flexible, simplifying the protocol, and researching ways to make verification less dependent on storing large amounts of state. Older roadmap diagrams sometimes group these themes into six named phases. Those labels can be useful historical context, but they should not be read as a current checklist with fixed status or delivery dates.

What this means for users and developers

Most protocol upgrades do not require ordinary ETH holders to move their assets. Node operators and validators need to follow client release and upgrade instructions when an activation date is announced. Application developers should test against the relevant test networks and check whether changes to gas accounting, transaction behavior, or client interfaces affect their software.

For users comparing Ethereum with other networks, roadmap targets are only one part of the picture. Actual fees, throughput, decentralization, and reliability depend on what ships and how people use the base layer and its connected networks. No single target such as transactions per second captures all of those trade-offs.

Social Media Sentiment

A small, specific sample from the October 18, 2026 r/ethereum daily discussion illustrates a practical question around Glamsterdam: if the upgrade expands available blockspace, will demand use that capacity, or could capacity grow faster than usage? One commenter framed block utilization as a test of whether the expansion is economically useful. This is one commenter’s view in a community discussion, not a representative measure of Ethereum users or a forecast of the upgrade’s outcome. Read the Reddit discussion.
