Highlights from ACDE Call #225: Ethereum’s Rocky Road to Scalability

Is Ethereum’s relentless pursuit of scalability and decentralization hitting a brick wall? The All Core Developers Execution (ACDE) Call #225, a crucial gathering of Ethereum’s core team, laid bare the triumphs and tribulations of the recent Fusaka hard fork while setting the stage for the upcoming Glamsterdam upgrade. From crippling node issues to governance gridlock, this meeting exposed the gritty reality of building a blockchain powerhouse.

• Fusaka Fallout: Successful fork tainted by a 79% Prysm node participation drop due to outdated code issues.
• Glamsterdam Blueprint: Over 40 EIPs sorted to sharpen focus for the next major upgrade.
• FOCIL Frustration: Censorship resistance proposal delayed to Heka fork amid decision-making woes.

Fusaka Hard Fork: Triumph and Turmoil

For the uninitiated, a hard fork in the blockchain world is a major update to the network’s rules, requiring all participants—node operators, validators, and users—to upgrade their software to stay compatible. The Fusaka hard fork, Ethereum’s latest big leap forward, was rolled out with much fanfare, marking another step in its post-Merge journey toward efficiency and scalability after shifting to Proof of Stake in 2022. But the celebration was short-lived. A major snag hit Prysm, a widely used client software for Ethereum’s Consensus Layer, where participation nosedived to a dismal 79%. The culprit? A lingering heuristic flaw from the Capella upgrade days that forced nodes to regenerate old, irrelevant states—think of it as a computer obsessively re-reading ancient, useless files. This caused massive processing overloads and missed attestations, meaning validators couldn’t confirm transactions on time, slowing down the network.

Thankfully, Ethereum’s core team didn’t sit idle. They deployed a temporary feature flag—a quick software toggle that limits unnecessary state regeneration—to stabilize Prysm nodes. The result? Network participation rebounded to healthy levels, showcasing the kind of cross-client coordination that keeps Ethereum ticking. A permanent fix, along with a detailed post-mortem to dissect what went wrong, is promised within a week of the call, as discussed in the recent ACDE Call #225 summary. Still, let’s not sugarcoat it: this kind of glitch in a blockchain as critical as Ethereum is a stark reminder that even giants can stumble over old code ghosts. Minor hiccups were also reported with other clients like Nimbus and Nethermind, but they paled in comparison to Prysm’s near-catastrophe.

BPO1 Activation: A Quiet Boost

While Fusaka’s technical drama took center stage, a smaller but noteworthy update emerged with the upcoming activation of BPO1, set to increase block counts roughly a week after the meeting. For node operators—those individuals or entities running the software that powers Ethereum’s network—this is a no-fuss change requiring zero action. It’s a subtle tweak to enhance operational capacity, but it quietly underscores Ethereum’s ongoing effort to optimize performance without fanfare.

Glamsterdam Fork: Scoping Ethereum’s Future

Looking ahead, the Glamsterdam fork emerged as the next pivotal milestone on Ethereum’s roadmap. To dodge the chaos of past upgrades, the core team unveiled a structured scoping framework, meticulously sorting over 40 Ethereum Improvement Proposals (EIPs)—suggested changes or features for the network—into two categories: “Consider for Inclusion” (CFI) and “Deferred for Inclusion” (DFI). This isn’t just paperwork; it’s a calculated move to streamline Glamsterdam’s goals and avoid biting off more than the network can chew. By narrowing the active list, developers aim to deliver a focused upgrade that doesn’t buckle under complexity.

Yet, not everything is neatly tied up. Several contentious issues remain on the table, each with massive implications for Ethereum’s scalability and security. Core gas repricing—adjusting how transaction fees are calculated—looms large, as does state growth repricing, which tackles the ballooning data burden on nodes. Then there’s contract size expansion strategies to enable more complex smart contracts, log indexing improvements tied to EIP-7745 for better data tracking, post-quantum security strategies to future-proof against emerging cryptographic threats, and debates over prioritizing non-protocol EIPs. For everyday users, gas repricing could mean cheaper DeFi transactions, while validators worry state growth might jack up hardware costs. These unresolved threads aren’t just technical—they’re make-or-break for whether Ethereum stays ahead of rivals like Solana or Polkadot, who are laser-focused on speed and cost.

FOCIL Deferral: Governance Gridlock Bites

One of the juiciest discussions revolved around the FOCIL proposal, officially EIP-7805, designed to strengthen Ethereum’s censorship resistance—a cornerstone of decentralization in a world where centralized powers increasingly eye blockchain control. There’s no denying FOCIL’s importance; the core team broadly agrees it’s vital. Yet, it got kicked down the road, deemed unsuitable for Glamsterdam due to unresolved technical complexities and a maddening split in decision-making between the ACDE (Execution Layer) and ACDC (Consensus Layer) groups. Instead, a public pre-commitment was made to prioritize it for the later Heka fork. Delaying censorship resistance feels like a gut punch to Ethereum’s ethos—decentralization shouldn’t be held hostage by bureaucratic red tape.

This deferral isn’t just a scheduling quirk; it exposed raw frustration among contributors. Repeated “temperature checks” on proposals like FOCIL—essentially polling for consensus over and over—drew sharp criticism for wasting time. The fragmented governance structure, with decisions split across different developer factions, is slowing progress to a crawl. Let’s call it what it is: a bureaucratic mess. If Ethereum doesn’t untangle these knots, it risks handing faster-moving competitors an open goal. Imagine Solana or even newer chains capitalizing on this inertia—Ethereum’s innovation engine could stall at the worst possible time.

Process Tweaks: Transparency on the Horizon?

On the procedural front, there’s a silver lining. A push to update EIP-1—the foundational guideline for how EIPs are proposed and adopted—aims to codify the “headliner process,” a newer mechanism to streamline fork planning. Alongside this, refreshing the official EIPs website for better accessibility was floated as a way to demystify Ethereum’s development for newcomers. These might sound like small potatoes, but they’re critical for onboarding fresh talent and maintaining trust in a project as sprawling as this. If Ethereum wants to keep its community tight-knit and growing, transparency isn’t optional—it’s mandatory.

Logistically, the holiday season threw a wrench in the schedule, with the ACDC call on December 25 and the ACDE call on January 1 canceled. To keep the gears turning, a potential replacement slot in an ACDT window was proposed. It’s a minor detail, but it speaks volumes about the dedication driving Ethereum’s core team, even when the world hits pause for festivities.

Ethereum’s Bigger Picture: Can It Keep Up?

Zooming out, ACDE Call #225 paints Ethereum as a high-stakes experiment in balancing cutting-edge tech with the messy reality of decentralized governance. Since The Merge in 2022 rewrote its architecture to Proof of Stake, each hard fork—Fusaka, Glamsterdam, and beyond—has been a litmus test for whether Ethereum can deliver on sky-high expectations for scalability, energy efficiency, and security. The Prysm node fiasco shows even the best plans can crumble under technical weight, while governance spats over FOCIL highlight that consensus in a decentralized system is often a brutal slog.

Here’s a devil’s advocate take: Is Ethereum playing it too safe by delaying critical upgrades like censorship resistance, especially as global pressures for blockchain control mount? On the flip side, rushing unready proposals could destabilize the network further—look at Fusaka’s near-miss. Compared to leaner chains like Solana, which prioritize speed over complexity, Ethereum’s intricate upgrade process feels both a strength and a shackle. And from a Bitcoin maximalist lens, this complexity underscores why Bitcoin’s simplicity remains king for store-of-value purists. Yet, Ethereum’s innovation—smart contracts, DeFi, NFTs—fills niches Bitcoin wisely avoids, carving a unique role in this financial revolution.

For stakeholders, the stakes are tangible. Validators took a hit from Prysm’s drop, missing out on rewards during downtime. Users await gas repricing for cheaper transactions, while developers eye contract size expansions to build bolder dApps. Glamsterdam and Heka could redefine Ethereum’s edge, potentially challenging Bitcoin’s dominance in developer mindshare if executed right. But persistent delays or unresolved EIPs might see rivals snatch that momentum. As champions of effective accelerationism, we say Ethereum’s grit is commendable—push the boundaries, damn the hurdles—but only if it doesn’t trip over its own feet.

Key Takeaways and Burning Questions
