Ethereum’s Next Frontier: Glamsterdam, Hegotá, and ACDC Call #175 Updates

Ethereum has once again taken center stage in the blockchain arena with critical updates unveiled during the All Core Developers Consensus (ACDC) Call #175. The spotlight shines on two major advancements: the Glamsterdam upgrade’s push for native proposer-builder separation and the Hegotá upgrade’s focus on censorship resistance. These developments signal Ethereum’s relentless drive to fortify its protocol, but they also come with technical hurdles and unanswered questions. Let’s dive into the details of what’s unfolding, why it’s pivotal, and where the risks lie.

• Glamsterdam Focus: Enshrined Proposer Builder Separation (ePBS) advances with Devnet Zero testing for client interoperability.
• Hegotá Priority: Fork Choice Enforced Inclusion Lists (FOCIL) selected to combat censorship in block building.
• Community Caution: Optimism for innovation tempered by realistic timelines and technical challenges.
• Looming Concerns: Risk of overcomplicating Ethereum’s core protocol with ambitious enhancements.

ePBS: Breaking Free from MEV Boost’s Shadow

The Glamsterdam upgrade is making waves, primarily due to its centerpiece: Enshrined Proposer Builder Separation, or ePBS. For those new to Ethereum’s inner workings, validators on the network handle two key roles—proposing blocks (selecting transactions to include) and building blocks (often optimizing for profit through reordering transactions). This optimization is tied to Maximum Extractable Value (MEV), where builders prioritize transactions for higher fees or arbitrage gains. Picture a ticket scalper cherry-picking the best seats to resell at a premium—that’s MEV in action, and it can skew fairness on the network.

Currently, Ethereum uses an external tool called MEV Boost to separate these proposing and building roles, preventing any single entity from monopolizing both. While functional, MEV Boost isn’t part of Ethereum’s core rules, leaving the network vulnerable to centralization risks. A small group of relayers controls most MEV Boost activity, and if they face regulatory pressure or collude, Ethereum’s neutrality could erode. ePBS aims to fix this by embedding proposer-builder separation directly into the consensus layer, eliminating reliance on third-party systems. It’s a move to bring a critical operation under Ethereum’s own roof, enhancing decentralization and reducing trust assumptions. For more insights on the discussions around these updates, check out the summary of the recent ACDC Call #175.

Testing for ePBS is progressing through Devnet Zero, an early-stage test network focused on ensuring different client software can work together seamlessly rather than chasing performance metrics. Teams behind clients like Lighthouse have started local trials, uncovering minor but telling issues—such as empty blocks, where no transactions are included due to syncing delays or timing mismatches. The ePBS specification remains in alpha, far from polished, with ongoing debates over details like proposer deadline timing to prevent stalled blocks. The immediate goal is to stabilize at least two or three client implementations before a public Devnet Zero launch. While there’s guarded optimism about meeting this target, Ethereum’s history of delayed rollouts keeps expectations in check. No one’s betting the farm on a flawless timeline here.

FOCIL: Fortifying Ethereum Against Censorship

On the Hegotá upgrade front, developers have locked in Fork Choice Enforced Inclusion Lists (FOCIL) as the Consensus Layer’s flagship feature. If this sounds like jargon, let’s simplify: FOCIL is a mechanism that allows validators to enforce transaction inclusion using Ethereum’s fork choice rules—the logic that decides which blockchain version is the “canonical” one. Why is this a big deal? In the current setup, block builders can cherry-pick transactions, potentially excluding ones they dislike due to bias or external pressures like government regulations. FOCIL flips the script by giving validators a tool to fight back, raising the cost of censorship and ensuring transactions aren’t arbitrarily sidelined.

The decision to prioritize FOCIL over a competing proposal (a two-dimensional partial reconstruction model) came with strong backing from client teams, community feedback, and key ecosystem players like Lido. However, developers are treading carefully, resisting the urge to overload Hegotá with additional features. Their focus is twofold: polishing ePBS for Glamsterdam and ensuring FOCIL integrates smoothly with Ethereum’s execution layer—where transactions are processed—without sparking chaos or unintended side effects. It’s a deliberate, measured approach to avoid biting off more than the network can chew.

The Backstory: Why Ethereum Needs These Fixes

These upgrades aren’t random experiments; they address long-standing pain points. Since Ethereum’s shift to Proof of Stake with The Merge in 2022, reliance on external tools like MEV Boost has irked decentralization advocates. A handful of relayers dominate MEV Boost traffic, creating a single point of failure—if they’re compromised or censored, the network suffers. Real-world pressures, like U.S. sanctions enforced through the Office of Foreign Assets Control (OFAC), have also led to instances where validators delayed or excluded transactions tied to blacklisted addresses. Such events have fueled urgency for solutions like ePBS and FOCIL, which aim to hardwire decentralization and censorship resistance into Ethereum’s DNA, safeguarding its ethos of openness amid growing external scrutiny.

The Rough Road Ahead: Technical and Strategic Risks

Let’s cut through any rose-tinted glasses—these advancements face serious headwinds. For ePBS, syncing multiple client teams is a logistical nightmare. Each client, like Lighthouse or Prysm, operates on different codebases with unique quirks, and Devnet Zero’s empty block issues hint at deeper timing or compatibility problems that could escalate on mainnet. The alpha status of ePBS specs adds another layer of uncertainty; last-minute changes could derail progress or frustrate developers. A rushed rollout risks bugs or network splits, and Ethereum’s past hiccups serve as a sobering reminder to prioritize caution over speed.

FOCIL isn’t immune to challenges either. Integrating it with the execution layer demands precision—screw this up, and transaction processing could slow or new vulnerabilities might emerge. Imagine a bad actor gaming the inclusion list to stall consensus; it’s a niche but plausible attack vector. Playing devil’s advocate, we must ask if embedding complex mechanisms like ePBS risks turning Ethereum into an unwieldy beast. Bitcoin purists already mock it as an over-engineered contraption—bloating the protocol further could make audits or future upgrades a living hell. The trade-off for better security and fairness might be worth it, but it’s not a guaranteed win.

A Bitcoin Maximalist’s Side-Eye

Wearing my Bitcoin maximalist hat for a moment, I can’t help but smirk at Ethereum’s obsession with complexity. Bitcoin’s strength lies in its stripped-down design—a rock-solid protocol that doesn’t try to be everything to everyone. Security and simplicity reign supreme, while Ethereum seems to stack feature upon feature, risking instability. That said, I’ll tip my cap to Ethereum’s niche. Smart contracts and decentralized applications (dApps) demand this kind of tinkering—Bitcoin isn’t built for that sandbox. Still, one has to wonder if ePBS and FOCIL are essential armor or just shiny distractions from core vulnerabilities. Time will tell if Ethereum’s ambition overreaches.

Ethereum in the Competitive Arena

How do these changes stack Ethereum against its rivals? Compared to Bitcoin, ePBS and FOCIL highlight Ethereum’s knack for adaptability. Bitcoin’s base layer doesn’t grapple with MEV or granular censorship resistance—it’s a blunt instrument for peer-to-peer money. Ethereum, however, aims to be a programmable platform, and these upgrades cement that edge. Against layer-1 competitors like Solana, which chase raw throughput, Ethereum’s focus on decentralization via ePBS could attract users wary of Solana’s validator concentration or outage history. But there’s a catch—Solana’s leaner design might lure developers tired of Ethereum’s perpetual upgrade grind. Ethereum isn’t just debugging code; it’s defending its crown in a cutthroat field.

What This Means for Ethereum Users

Beyond the tech speak, how do these developments hit home for everyday users and investors? If ePBS delivers, it could curb the hidden “MEV tax” users pay when transactions are reordered for profit, possibly stabilizing or reducing fees. Validators and miners, though, might see MEV revenue dip as separation tightens. FOCIL offers a different win: reassurance that your transaction won’t be censored due to a builder’s whim or regulatory overreach. For users—and even regulators—this could bolster Ethereum’s credibility as a neutral platform. These aren’t headline-grabbing perks, but they lay groundwork for a more reliable, trustworthy network over the long haul.

Community Buzz: Excitement Meets Skepticism

Outside the core dev circle, Ethereum’s wider community is vocal on platforms like X and Reddit. Many hail ePBS as a overdue fix for MEV Boost’s centralization flaws, though smaller developers grumble about potential delays stretching into 2025. FOCIL enjoys broader applause as a defiant stance against censorship, but a few skeptics warn it could muddle consensus in rare edge cases. And let’s shut down the nonsense peddled by some social media hype-mongers—ePBS won’t “eradicate MEV” in a snap, and FOCIL isn’t a magic shield against all exclusion. That’s pure garbage, and we’re not here to peddle fantasies. These are incremental gains, not overnight miracles, and we’ll call out any shilling for what it is: bullshit.
