What brings to the network?

The next great update in Ethereum after sin has a tentative date. If this followed the same Hard Fork plan on the network, Fusaka would arouse on Ethereum between November 5 and 12, after two test phases between the end of September and the beginning of October. This update will bring improvements in the scalability and the Ethereum user experience according to Forkcast, an educational project in Ethereum.

«Fusaka derives from ‘Fulu’ (update of the consensus layer, called by a star) and ‘Osaka’ (update of the execution layer, named for a devcon).”

Forkcast, educational project.

The group of developers reached consensus on 13 proposals to improve Ethereum (EIP)that will reach the network protocol with Fusaka. In total, 33 proposals were rejected. Some of the excluded will arrive in Glamsterdan, a fork of Ethereum scheduled for 2026, such as EIP-7607, whose exclusion caused some agitation between the developer community and deserves a separate article.

EIP-7594 is the main proposal that Fusaka will introduce. It will include peerdas, a system of data availability in pairs which allows the nodes to “specialize” in the storage of different kinds of data and their verification. In general, Peerdas enriches the storage capacity of the network.

Specifically, this system brings the following benefits:

• Reduces transaction costs in second layers (L2) as base, arbitrum and others.
• It allows to climb to 128 BLOBS (data packages outside the chain) per block over time.
• Host lighter nodes that only store a fraction of the data.

According to Ethereum developers, Peerdas will help Ethereum to support heavier applications and with higher requirements. Also to “compete with high -speed block chains” and “paves the way for complete Danksharding.”

EIP-7642 Eliminate the requirement that the nodes store obsolete data from the Ethereum Network. This will exempt the 530 GB bandwidth for each synchronization, which will result in faster synchronizations and lighter nodes.

EIP-7823 establishes an upper limit in the pre-compilation of modexp data inputs, which has been a historical source of consensus errors by allowing unlimited entries. In other words, this proposal will contribute to eliminating excess unnecessary code (> 8,192 bits) in Ethereum programming, preventing the possibility of service denial attacks (two) and racing the path for the use of more efficient code in the virtual machine of Ethereum (EVM).

EIP-7883, complementary to this, increases the cost of modexp gas from 200 to 500 gas and doubles the costs for large tickets of more than 32 bytes, this on the occasion of discouraging the two attacks and that the cost of using that pre-compilation reflects the real computational expenses.

EIP-7825 Enter a higher gas limit for transactions in Ethereumwhich will now be 30 million for individual transactions. The intention of this improvement proposal is to avoid that each individual transaction consumes most of a block on the Ethereum network.

“The objective is to guarantee more just access to block space and improve network stability” with EIP-7825. That said, and in apparent exclusion of the previous proposal, EIP-7935 seeks to raise the gas limit per block to increase the execution capacity of Ethereum and, therefore, its performance and scalability.

In summary, Fusaka has smaller gas limits for individual transactions and larger limits for blocks. In other words, Ethereum will be able to process more block transactions, as long as they do not exceed the theoretical gas limit of 30 million.

EIP-7892 will allow more constant updates of the Blobs through bifurcations that only affect the parameters of these data packages.

“Instead of waiting for an important update, Ethereum can make smaller and frequent adjustments in Blobs’s ability to adapt to the changing demand of layers 2,” summarizes Forkcast.

Complementary to this improvement proposal, also included in Fusaka, is EIP-7918, which solves problems in the Blobs rates market (preventing its collapse) by imposing a base rate for these data packages. EIP-7918 “guarantees that Blobs consumers pay a fair market price for the process and reduces drastic increases in rates.”

EIP-7917 helps anticipate the calendar of block proponents and its respective list of transactions in the Ethereum Network. This proposal introduces an ability to precalculate and store this programming, making it deterministic and predictable.

With this improvement, Fusaka seeks to mitigate the action of maximum removable value (MEV) in Ethereuma mechanism through which validators include transactions in the blocks according to the economic benefit that they report them. This measure may help the list of transactions included in the next block to be more heterogeneous and fair.

EIP-7934 imposes an upper limit of 10 megabytes (MB) to the Ethereum blocks. This proposal seeks to ensure the stability of the network and avoid attacks two. «Currently, the blocks can grow a lot, which slows the spread of the network and increases the risk of temporal bifurcations. This limit guarantees that the blocks remain within a reasonable size that the network can process and propagate efficiently, ”summary in Forkcast.

EIP-7939 Add a new operation code to the Ethereum virtual machine called CLZ (Count Leading Zeros), An essential operation in mathematical calculations in cryptography. The left zeros count in solidity is currently complex and expensive, summarizes Forkcast. This operation code makes it much cheaper and more fast, as CLZ will allow the number of zeros to be more efficiently at the beginning of a 256 -bit number.

This implementation benefits the application of zero knowledge tests in Ethereum, a mechanism of reusable keys that hide critical information from transactions.

EIP-7951, finally, add support for a cryptography curve called SECP256R1, which will allow verifying devices that use that cryptographic scheme, like iPhones, Android and some hardware wallets. This improvement promises to improve user experience in Wallets and mobile devices, expanding Ethereum infrastructure.

In summary, Fusaka represents the next technical milestone in Ethereum, consolidating 13 EIP to improve scalability, efficiency and user experience.

Its central proposal, peerdas, will allow lighter nodes and the expansion of storage in Blobs, vital for layers 2. Other key improvements include the elimination of obsolete data (EIP-7642), fairer gas limits (EIPS 7825 and 7935), protection against attacks two (EIPS 7823, 7883 and 7934), cryptographic efficiency (EIP-7939), and compatibility with more devices, through SECP256R1 (EIP-7951).

Fusaka points to a lighter, scalable and accessible Ethereum, prepared for more complex applications and future demand.
