Ethereum's Next Upgrade Roadmap: Glamsterdam, Hegotá and the Post-Quantum Clock

Ethereum's next upgrade story is not “more transactions, cheaper gas, everyone celebrates.” The new roadmap is more ambitious—and much less tidy.

In a September 7 protocol update, the Ethereum Foundation described how work is moving from the approaching Glamsterdam upgrade into Hegotá scoping and then through a multi-fork program aimed at making Ethereum's execution, consensus and data layers resistant to quantum attacks by December 2029.

That is a serious deadline attached to a difficult engineering problem. It also comes with a warning from the team itself: the required schedule is aggressive, several forks will need to overlap, and future ordering may change as research matures.

This is a roadmap, not a train timetable. Still, it tells users, developers and investors what Ethereum's protocol engineers consider important enough to fight for.

The Foundation's current plan targets Glamsterdam for December 2026. With that fork approaching mainnet, the protocol cluster has entered Hegotá's scoping season.

According to the update, 62 EIPs were proposed for inclusion. Multiple retrospectives, 16 contribution templates and working sessions involving roughly 60 researchers and engineers helped produce a priority list.

That process matters because an upgrade cannot safely contain every good idea. Ethereum's protocol has a limited testing budget, and every extra feature expands the number of interactions client teams must reason about. “Ship everything” is an exciting slogan right up until the network has to ship.

The Foundation identified two SFI-stage headliners that need to work together:

• EIP-7805, Fork-choice enforced Inclusion Lists (FOCIL): This proposal is designed to strengthen censorship resistance by letting multiple validators require eligible transactions to appear in a builder's block.
• EIP-8141, Frame Transactions: This introduces a more programmable transaction model for validation, execution and fee payment, creating a native path toward account abstraction and cryptographic agility.

In plain language, FOCIL tries to make it harder for a powerful block builder to quietly exclude valid transactions. Frames aims to give accounts more flexible security and authorization rules without adding a separate hard fork for every new signature scheme.

The interaction is the hard part. Inclusion rules must understand which transactions are valid and eligible; a new transaction model changes that surface. The Foundation says testing the two together is Hegotá's central engineering commitment.

Today's Ethereum signatures are not expected to withstand a sufficiently capable quantum computer. Nobody can schedule “Q-day,” the moment such a machine becomes practical, and credible estimates vary widely. The Foundation chose to plan for it arriving as early as 2030 and set a December 2029 readiness target.

The current strawmap places full post-quantum readiness five hard forks after Glamsterdam. Hitting December 2029 under that ordering would require an average cadence of about 7.2 months per fork. A contingency path places minimum viable post-quantum protection earlier and allows a roughly 12-month cadence, but with reduced guarantees while the full design is completed.

That target is not a promise that quantum computers will break Ethereum in 2030. It is risk management: cryptographic migrations take years, and waiting for certainty would mean starting when the clock is already loud.

The roadmap is broader than quantum resistance. Ethereum is advancing five connected tracks:

1. Faster finality

The goal is to reduce finality from minutes toward seconds. The leading direction separates finality from block production and introduces a dedicated finality mechanism. Specifications and prototypes are aimed at a later fork currently called I*.

2. Post-quantum security

Execution accounts can gain cryptographic agility through Frames, allowing signature schemes to change more flexibly. Consensus is tougher because its core cryptography can only change through coordinated forks and must be tested extensively before deployment.

3. Protocol privacy

The team wants privacy to become a protocol guarantee rather than something users obtain only by trusting an application or intermediary. Candidate building blocks include keyed nonces and access to recent state roots for private transactions.

4. Sustainable state

Ethereum must stop state growth and historical access from becoming a permanent bottleneck. The plan includes a new trie, sustainable state growth and decentralized access to current and historical data.

5. zkEVM progression

Execution proofs are meant to move from optional, to expected, and eventually to mandatory. In the long-run design, validators verify succinct proofs instead of independently re-executing every transaction.

These are not isolated upgrades. Account security affects post-quantum readiness; formal verification supports the zkEVM and cryptography; state design affects scaling. Pull one thread and several others move.

Protocol progress is not a guaranteed price catalyst. A technically excellent upgrade can arrive during a hostile macro market, while ETH can rally before a feature reaches mainnet. Our Bitcoin and Treasury-yield report shows why the discount-rate environment still matters across crypto.

The roadmap is nevertheless relevant to Ethereum's long-term value proposition. Better censorship resistance, safer account models, usable privacy, manageable state growth and proof-based validation all address the network's ability to remain credible infrastructure.

The risk is execution. A seven-to-nine-month fork rhythm leaves little room for major delays. Parallel development can accelerate delivery, but it also increases coordination demands across client teams, researchers, security reviewers and application developers.

Do not judge the roadmap by the number of EIPs in a slide. Watch evidence move through the Foundation's own pipeline:

Research → EIP → prototype → devnet → proposed for inclusion → considered for inclusion → scheduled for inclusion → mainnet.

The labels represent rising confidence, not certainty. The practical checkpoints are:

• whether Glamsterdam reaches mainnet on its current target;
• whether FOCIL and Frames remain Hegotá's paired centerpieces;
• whether client implementations begin in late Q4 as planned;
• whether privacy additions pass the necessity and testing bar;
• and whether the I* and J* post-quantum components mature without crowding out basic network safety.

We will track those milestones in Crypto News. For the regulatory layer surrounding protocol development, see our SEC crypto-rule explainer, or browse the full CryptoCardHQ news desk.

Ethereum's roadmap now has a clearer spine: ship Glamsterdam, keep Hegotá tightly focused on FOCIL and Frames, and use the following forks to advance finality, privacy, state reform, zkEVM adoption and post-quantum protection.

The December 2029 target is aggressive by design. The most encouraging part is not the date itself; it is the decision to make trade-offs visible before the code reaches mainnet.

Ethereum is attempting renovation while the building remains open, full and economically important. That is not the easiest way to upgrade a system. For a decentralized network, it is the only way available.
