Ethereum’s New Upgrade: Why Fusaka Might Just Be Your New Favorite Fork 🍴🚀

by

In a twist of fate worthy of a Gogolian tale, our beloved Ethereum is preparing for its next grand performance, known as the Fusaka, set to dazzle (or bore) onlookers in the enchanting month of November. This masterstroke promises to enhance the inner workings more than the glittering façade, akin to a magician who pulls rabbits out of hats while privately musing over the mechanics of hats themselves. 🎩✨

  • In this dramatic endeavor, Ethereum seeks to unveil Fusaka this coming early November, a diligent array of technical improvements lurking beneath the surface like a shy suitor in a crowded ballroom.
  • Fusaka, unlike previous upgrades that mingled with the audience, chooses instead to fix its bowtie and improve the costly bottle of wine known as performance, scaling, and node security.
  • This is all part of Ethereum’s ambitious race against the clock, striving to maintain harmony amid a maelstrom of demands, akin to a conductor managing a cacophony of rogue instruments.

As we stand on the precipice of protocol change, Fusaka is entering its final rehearsal, with the main event tentatively scheduled for early November 2025. An unmistakable sequela to the Pectra debacle, this upgrade promises to continue Ethereum’s relentless pursuit of accelerated progress.

While Pectra greeted users with a flourish—like a performer taking center stage—Fusaka dons its cloaks of secrecy to perform a back-end ballet of protocol refinement, enhancing performance while fumbling with the tuning forks of scalability and resistance.

What joy awaits us in the absence of flamboyant changes! Instead, Fusaka humbly bundles 11 Ethereum Improvement Proposals (EIPs), expertly refining core protocol parameters, enhancing security, and optimizing that precious gas efficiency, akin to squeezing every last drop of chocolate frosting from the bowl. 🍫

Who proposed and why

Ah, but what would an upgrade be without its heroes? EIP-7825 gallantly enters stage left, protecting nodes like a watchful guardian against an onslaught of spammy messages, while the audacious proposal to raise the block gas limit to a staggering 150 million is met with cheers and jeers, much like a circus act. Expect slower block spreading, dear friends, and a data storage saga yet to unfold! 🎪

Oh, and don’t forget EIP-7907, meant to double the code size. Like a ghost at a ball, it vanished to avoid a testing disaster—perhaps returning to haunt the next gathering of forks? 👻

▶️ devnet updates
▶️ Just the middle of 2025 & we’re swimming in time to roll out Fusaka this year, right?
WRONG. If we want it in time for Devconnect, we need our timeline CRYSTAL CLEAR!
Let’s dive into the details—can we reel in client releases within a dwindling month and a half? 😳

As the community voices chimed in, the committed Nixo urged everyone to remain strictly punctual, emphasizing the significance of timely client releases before the grand Devconnect, where developers gather like moths to a flame—no pressure! 🔥

What’s in the box

And now, the moment you’ve been waiting for! A delectable morsel of discerning features that Fusaka brings to our proverbial banquet:

  • Higher gas limit. A bounteous raising of the block gas limit to 150 million units—so as to squeeze more transactions into the proverbial soup pot, lowering fees and ramping up the speed under pressure like a chef in a bustling kitchen.
  • Security boosts (EIP-7825). Fresh checks to fend off attackers, making our nodes as sturdy as a guard standing watch at a royal gala, ensuring fewer disruptions than a poorly timed drum roll.
  • Code size and metering adjustments. EIP-7907 may have fled the scene for now, but its increase of the code size limit may still dazzle us in future escapades.

Fear not! These changes shall not ruin the delicate dance of most smart contracts; rather, they promise to carry a heavier load with grace and security, like a seasoned juggler. 🎭

How did we get here

The road to this upgrade follows a six-month rhythm, akin to the cyclical stirrings of fate. Pectra made its entrance in May with delightful user-facing features, but shortly after that, whispers of Fusaka echoed through the halls of Ethereum like the rustling of parchment. 📜

In clandestine gatherings, the AllCoreDevs—our beloved band of tech troubadours—debated the merits of EIPs like performers selecting their finest acts. On August 1, the chosen ones shall be revealed, trailing a month or two of modifications like a carefully orchestrated overture. The upgrade path for Fusaka is as follows:

  1. Devnet launch. Our first private developer soirée commenced in mid-July 2025, giving a handful of sages a chance to test their charms amidst controlled company.
  2. Public testnets. Look out, world! Two public testnets are rolling out in late September and October 2025, inviting the curious community to join in the merriment and bug-hunting. 🔍
  3. Mainnet hard fork. If the universe aligns, Fusaka is prepared to grace the Ethereum stage in early November, just in time to steal the show at Devconnect in Buenos Aires (Nov. 17-22).

Should such celestial events unfold in harmony, developers will tally testnet results by November and unleash the upgrade with a flourish, ensuring every participant in the Ethereum waltz dances alike.

As time flows ever onward, it becomes clear that users flock to blockchains capable of speed, economy, and security. Fusaka, while not a grand transformation, stands as an essential stepping stone, enabling Ethereum to remain competitive in a world of swifter chains and layering sorcery. May it bolster our defenses and invite fresh guests to our DeFi soirée, where games and applications can cavort like merry companions! 🎉
