Ethereum is Changing: Here’s What to Expect in the New Update Coming Soon

Ethereum (ETH) has started the countdown for its next major network upgrade, Fusaka, which will go live on December 3.

Described by the Ethereum Foundation as “a step forward in proving that the network can grow to meet global demand without sacrificing decentralization,” Fusaka offers far-reaching innovations for users, developers, and enterprise actors alike.

One of the most notable aspects of the update is its goal of bringing Ethereum’s user experience closer to the speed and ease of consumer applications. Data scaling will reportedly make transactions nearly instantaneous, while mobile wallets will be able to offer hardware-compatible passkey support for more secure logins at a lower cost.

PeerDAS (EIP-7594), Fusaka’s most critical technical component, directly impacts the rollup and layer-2 ecosystem. This model, which uses data sampling for verification, increases the network’s data processing capacity by up to eight times, reducing blob fees and freeing up growth for rollups. This increased capacity is expected to translate into lower transaction fees and greater scalability on the user side.

For app and DeFi developers, Fusaka paves the way for “instant” interactions. Pre-approval-based mechanisms reduce transaction latency from minutes to milliseconds, while lower costs create a new layer of usability. However, developers working with very large transactions should be mindful of the 2²⁴ per transaction gas limit.

Node operators will also be directly affected by the update. The block gas limit, currently around 45 million, has been increased to 60 million, while the implementation of “history expiry,” which shortens history storage, will enable lighter and cheaper node operation in the long run. Conversely, bandwidth requirements for “super node” operators staking 4,096 ETH or more have been updated.

On the enterprise side, ease of compatibility is a key factor. Fusaka offers native support for the secp256r1 curve, ensuring a more natural fit with Ethereum’s enterprise security standards. Furthermore, blob base fee adjustments make transaction fees more predictable, further simplifying integration processes for large-scale organizations.
