Ethereum gains a new update tomorrow; see what changes.

Source: PortaldoBitcoin Original Title: Ethereum gains a new update tomorrow; see what changes Original Link: Ethereum will undergo a new update this Wednesday (3), the Fusaka, marking another chapter in the ongoing evolution of the world's second-largest blockchain. Since its inception, the network has undergone profound transformations, such as the migration to Proof-of-Stake at the Merge, the introduction of “blobs” in Dencun, and various performance optimizations, with each stage reflecting a long-term commitment to scalability, security, and efficiency.

This latest update continues this tradition by combining high-impact technical adjustments with structural changes that should benefit both users and developers.

Fusaka is considered one of the biggest scalability efforts of Ethereum so far, especially because it directly targets the bottleneck that arises with the growth of layer two solutions. As more transactions migrate to rollups, the need for space, speed, and efficiency to process large volumes of data on the first layer increases, and Fusaka aims to address exactly that.

The proposal introduces a new data verification system, expands operational limits, and strengthens resilience against attacks, all without compromising the decentralization of the network.

Another important aspect of this update is the improvement in the operating conditions of the Ethereum nodes. The network becomes lighter to synchronize, more predictable for validating blocks, and more robust against malicious behaviors.

Part of these changes involves new data structures, pricing adjustments, stricter limits for specific transactions, and the inclusion of features that facilitate interoperability with modern devices. The ultimate goal is to create a network capable of supporting an explosively growing ecosystem of decentralized applications, high-volume transactions, and more intuitive user experiences.

Fusaka Update of Ethereum in 13 points

The update brings together a set of 13 EIPs ( improvement proposals ) that affect different layers of the protocol. Below are the 13 topics, each representing a specific change introduced by Fusaka.

1. EIP-7594 — PeerDAS

PeerDAS scales blobs, the type of data used by second layers to send batches of transactions to Ethereum. The innovation is the “sampling” method: each node stores only part of the blob data, rather than the entire set. This allows for an increase in the capacity of blobs per block without requiring significantly larger nodes.

2. EIP-7892 — Blob-Parameter-Only (BPO) forks

BPO forks allow for an increase in the number of blobs per block over time without the need for a hard fork. The capacity is expected to double after one month and continue to grow gradually from 6 blobs per block to up to 128.

3. EIP-7918 — Blob base-fee tuning

The price of blobs is currently very low — usually 1 wei — because L2s stop posting blobs when L1 gas is high. This behavior causes the protocol to lower the price beyond what is necessary. The EIP creates a minimum reserve price linked to the L1 gas cost to correct this distortion.

4. EIP-7935 — Standard gas limit of 60M

The standard gas limit is now 60 million, expanding the space for transactions within each block. A higher throughput reduces congestion and tends to lower fees. This change is already active on the network.

5. EIP-7642 — Expiration notice of history

We from Ethereum now inform the block range that we can serve, update this range when necessary, and stop storing certain heavy elements, such as the bloom of receipts — which reduces more than 500 GB per synchronization.

6. EIP-7951 — Precompile secp256r1 (P-256)

The update adds native support for the signature system used by iPhones, Androids, and most modern devices. This paves the way for simpler wallet experiences, such as wallets with Face ID similar to Apple Pay.

7. EIP-7917 — Deterministic proposer lookahead

Ethereum now determines in advance who will be the next block proposer, allowing for trustworthy pre-confirmations on L1. Users can receive virtually instantaneous confirmations with guarantees from the future proposer.

8. EIP-7825 — Gas limit per transaction

Currently, a single transaction can consume all the gas of a block. This EIP imposes a limit of approximately 16.7 million gas per transaction, reducing vulnerability to spam attacks and congestive activities.

9. EIP-7934 — Block size limit (10 MB)

The EIP imposes a hard limit of 10 MB on the size of blocks at the protocol level. This measure prevents malicious agents from creating excessively large blocks, strengthening the network against denial-of-service attacks.

10. EIP-7910 — JSON-RPC method eth_config

A new RPC method allows nodes to report which hard fork they are running. This prevents consensus failures resulting from incorrect configurations before updates.

11. EIP-7939 — Opcode CLZ (count leading zeros)

The addition of the opcode CLZ allows counting leading zero bits in 256-bit values. This results in cheaper contracts to execute, smaller bytecodes, and lower proof costs in ZK systems.

12. EIP-7823 — Upper limit for the precompile MODEXP

The MODEXP function, used for cryptographic checks, was prone to bugs due to accepting inputs of unlimited size. The EIP sets a limit of 8,192 bits for each field, making the use of the function safer.

13. EIP-7883 — Increase in gas cost of MODEXP

In addition to the size limit, MODEXP was also underpriced — potentially consuming huge resources at a low cost. The EIP adjusts the gas price to better reflect the computational work required and to prevent abuse.

With this broad and comprehensive set of changes, the Fusaka update consolidates another important step in the evolution of Ethereum, reinforcing its position as the leading infrastructure for decentralized applications on a global scale. The expectation is that, following the update, Ethereum will become more robust, efficient, and ready to support the next wave of growth in the sector.
