Ethereum’s Big Upgrade: December 3, or Else? 🚀

by

In the year of our Lord 2025, the noble Ethereum community stands on the precipice of a momentous event, the Fusaka upgrade, set to descend upon them like a divine revelation on December 3. A timeline that has been accelerated, as if the developers were in a hurry to escape the confines of their own procrastination, was disclosed by the venerable Christine Kim, a sage in the realm of Ethereum’s development. 🧠

The confirmation of the mainnet activation date was made during the recent All Core Developers Consensus (ACDC) call, where the assembly of minds, ever the paragons of diligence, established schedules for public testnet upgrades and the blob-parameter-only (BPO) hard fork, a term as enigmatic as the riddles of the ancients. 🧩

Ethereum’s Fusaka Devnet Update

The developers, in their collective wisdom, reached a consensus with surprising ease, a feat that would make even the most stoic philosopher blush. Yet, the path ahead is not without its trials, as testing challenges loom like shadows over the horizon. Still, they remain resolute, barring any cataclysmic setbacks in the coming months. 🚧

Currently, two versions of the Fusaka Devnet are in operation. Devnet-3, a bastion of stability, with client teams diligently addressing software fixes. Meanwhile, Devnet-5, though stable, encountered issues earlier this week, akin to a symphony interrupted by a discordant note, with multiple client bugs and node misconfigurations. 🎻

These problems, though vexing, have not deterred the team, who have gleaned critical insights from a fleeting period of stability on Devnet-5, leading to recommendations for setting maximum blob counts for the upcoming hard forks. A testament to their perseverance, albeit with a dash of sarcasm. 😅

Looking ahead, the Ethereum Foundation’s EthPandaOps team, ever the diligent scribes, plans to roll out Fusaka Devnet-6 in the coming weeks to validate the findings from Devnet-5, as if the universe itself depended on it. 🌌

The team is focused on addressing a bug in the Prysm client that has emerged on Devnet-5, a conundrum that seems to be linked to high blob counts, resulting in orphaned blocks. Additionally, a recent update to the “ckzg” library has resolved prior issues, with a new version now available on GitHub, a beacon of hope in the digital realm. 📁

Upcoming Testnets 

The timeline for the Fusaka rollout is well-defined, with several key upgrades scheduled before the mainnet activation. Upcoming testnets include the Holesky upgrade on October 1, the Sepolia upgrade on October 14, and the Hoodi upgrade on October 28, each a step closer to the promised land. 🌅

Developers agreed that client teams should consolidate their releases for these testnet upgrades but can individually publish updates closer to the mainnet activation, a strategy as calculated as a chess master’s move. 🏰

In a separate but related development, the Ethereum community is engaged in discussions regarding the naming of a new consensus layer upgrade, referred to as Glamsterdam, a name that evokes both grandeur and confusion. 🎩

This will also involve the deprecation of the Sepolia testnet, though developers assured that there would be ample time for the community to adapt, with the new testnet expected to launch in March 2026, a date as certain as the rising sun. ☀️

At the time of writing, Ethereum trades at $4.460, recording a 3.5% price drop in the 24-hour time frame, a mere ripple in the vast ocean of speculation. Still, the altcoin registers gains of 80% year-to-date, a testament to its resilience, or perhaps the fickle nature of the market. 📈
