Ethereum is a decentralized platform that continually evolves through upgrades to address its shortcomings. It has undergone several upgrades in the past, such as The Merge, Dencun, and Pectra. But because it wanted to improve further, it was now Fusaka’s time to launch on the market.
Fusaka upgrade was scheduled for December 3, 2025, with the goals of reducing costs and improving scalability for Layer 2 networks.
Ethereum was developed from the outset to address Bitcoin’s shortcomings and offer better solutions. And it managed to do this, but to remain relevant, this platform actually needs to continue going through constant upgrades.
These upgrades will also play an essential role in the platform’s native token, Ether (ETH), and can help it attract greater demand. Ether is the second-largest crypto project by market cap, which is why it is one of the most important choices of a well-diversified portfolio.
When you want to invest in this coin, it is a good idea to consider the ETH price prediction, as this can help you develop better strategies and identify new market opportunities.
In this article, we will explore more insights into the Fusaka upgrade. Keep reading.
What are the upgrades that were present on the Ethereum Roadmap?
Fusaka is a significant crypto project, but this upgrade wasn’t developed overnight; it went through many improvements to reach this point. Here are some of the most critical milestones from the evolution of Ethereum:
- The Merge: This upgrade, implemented in 2022, significantly helped Ethereum by enabling a transition from an energy-intensive consensus mechanism to a more sustainable alternative. At first, Ethereum used a Proof-of-Work (PoW) consensus mechanism, in which miners had to solve complex mathematical problems to add new blocks and validate transactions. This consumed a lot of energy, which is why Ethereum has transitioned to a Proof-of-Stake (PoS) consensus mechanism.
- Shanghai/Shapella (2023): Proof-of-Stake requires users to stake an amount to validate transactions. This upgrade lets validators withdraw their staked ETH.
- Dencun: The March 2024 upgrade introduced blobs, reducing Layer 2 fees.
- Pectra: Pectra went live in May 2025 to improve the validator flexibility and increase the blob capacity.
- Fusaka: All these upgrades created the right environment for the Fusaka upgrade to appear and finally help Ethereum manage higher throughput.
The Fusaka upgrade: An overview
The Fusaka upgrade has introduced new Ethereum Improvement Proposals (EIPs) and other significant innovations, including:
PeerDAS
PeerDAS (Peer Data Availability Sampling), also known as EIP-7594, is an essential component of Ethereum that enables Layer 2 solutions such as Optimism and Arbitrum.
Validators need to handle data to ensure that the validation process completes on the dataset, which can lead to network bottlenecks in some instances. In other cases, the number of blobs was too high, so validators had to invest in expensive hardware to continue to stake.
The solution to these shortcomings is to avoid having validators download the entire data blobs. And this is precisely what the PeerDAS are maintaining, as the validators only need to download a small part, around 12,5% of the blob. The result is that validators will require 85% less bandwidth.
Block Gas limit
Every transaction on Ethereum requires gas, and with this upgrade, Ethereum is ready to address some of its shortcomings.
As a result, the block gas limit will move from 36 to 60 million gas units. Because of this, Ethereum will be able to process more transactions on the leading network and execute complex smart contracts.
Improvements on the Ethereum Virtual Machine (EVM)
Thanks to the Fusaka upgrade, the Ethereum Virtual Machine will also support more use cases. Here are the new features that improve this part.
- EVM Object Format (EOF): This structure separates code from data, enabling smart contracts to benefit from more efficient programming structures. Thanks to this approach, the smart contracts will be optimized and much easier to validate. This results in fewer errors and faster execution times.
- New Opcodes (EIP-7742): With the Fusaka upgrade, the EVM will receive opcodes, which are basic instructions designed to make cryptographic operations more efficient.
- EIP-7212: With this proposal, the EVM will benefit from more digital signatures, more hardware security modules, and support for mobile devices. This is why this upgrade could enable using the iPhone’s fingerprint sensors or Face ID to interact with some Ethereum apps.
How will the Fusaka upgrade help Ethereum?
Increase the institutional interest
The Fusaka upgrade can actually increase institutional interest and attract even more attention to this amazing blockchain.
This upgrade will help Ethereum increase its infrastructure maturity, and if it does, the big players will likely want to take part in the change.
This upgrade will also help Ethereum remain more competitive, as other blockchains have been launched to address their shortcomings.
Solana is one of them, and this platform was also named an “Ethereum killer”. As a result, Ethereum has to do something to remain relevant.
It offers more importance to the long-term goal
With the Fusaka upgrade, Ethereum will improve its scalability, which other blockchains have done better. But in this way, Ethereum will still have the upper hand in the market.
Other than this, developers will want to remain on this blockchain rather than move to other blockchains, which is a great bonus and will help Ethereum improve its long-term value.
Conclusion
The Fusaka upgrade is one of the most critical milestones in Ethereum’s recent evolution. Fusaka is the upgrade Ethereum had to undergo to sustain an ever-larger ecosystem and enable faster transactions on a blockchain capable of supporting more decentralized applications.
Ethereum is a platform that has truly revolutionized the use of smart contracts. But to remain the number one blockchain for developers, it also needed several upgrades, including Fusaka.
