In a March 1 post on X, Ethereum co-founder Vitalik Buterin shared details on Fusaka, which is expected to follow the Pectra upgrade.
The Pectra Upgrade is billed to go on the Sepolia testnet by March 5, on epoch 222464.
However, the Ethereum ecosystem is already discussing the next upgrade.
What is Fusaka Upgrade? Vitalik Buterin Explains
The Fusaka upgrade is expected to bring specific improvements to the Ethereum network.
This includes enhancements to the Ethereum Virtual Machine (EVM) and block capacity.
Based on Ethereum’s roadmap, this upgrade is expected to go live in 2026, but no specific date is in mind.
To this end, Buterin noted that Fusaka needs to get on a Layer-1 (L1) with Peer Data Availability Sampling (PeerDAS).
He highlighted the ideal parameter for this event as a 48/72 blob target/limit.
The Ethereum co-founder urged developers to focus on getting a Fusaka testnet with these blob parameters running the day after Pectra goes live.
A few Ethereum community members have reacted to the news, citing that it is a big, next-level, and exciting deal.
The wait for the Pectra mainnet launch is crucial for the best upgrade, especially because Fusaka will build on the foundation established by the former.
Much of its focus will be on incorporating Ethereum Improvement Proposals (EIPs) deferred from the Pectra upgrade.
Still, the goal will remain to enhance scalability, efficiency, and decentralization.
In the meantime, the full scope of Fusaka is still under discussion.
Developers are focusing on Verkle trees transition, EVM Object Format (EOF), and PeerDAS.
Ethereum Ecosystem and Recent Upgrades
In this past week, the Ethereum ecosystem has seen Pectra go live on the Holesky testnet.
However, this particular testnet is currently faced with some technical challenges, leading to Pectra’s failure to settle on it. Hence, developers are working on mitigation routes for Holesky.
From Holesky, Pectra is headed for Sepolia as both testnets are required to usher in a mainnet activation epoch for Pectra.
Apart from these upgrades, the Ethereum ecosystem has been drenched in several challenges, including a massive shakeup at the Ethereum Foundation.
During one WIRED coverage, Ethereum Foundation Executive Director Aya Miyaguchi allegedly rejected a “culture of competing and winning” and claims she failed to move fast enough on Ethereum’s scaling solutions.
These claims earned her some hostility from Ethereum community members and EF insiders.
Meanwhile, Miyaguchi has recently transitioned from being EF’s ED to becoming the President of the non-profit organization.
ETH Price Outlook
Ethereum price was trading for $2,228.88, following a 2.01% increase within the last 24 hours.
While this gain is mild, it is a notable recovery from the previous bearish levels recorded by the altcoin earlier in the week.
When they launched, several analysts and market observers had expected that massive spot Ethereum ETFs would bring the much-anticipated rally to ETH.
The price rally came, but it was only for a short time, and since that time, Ethereum has struggled to hit $3,000.
Miyaguchi’s transition and the general Ethereum Foundation leadership structure shift are expected to catalyze ETH price recovery.
Also, the series of upgrades in the ecosystem may trigger the price surge for the second-largest cryptocurrency by market capitalization.
