What Does the Fusaka Upgrade Mean?

The Fusaka upgrade is a significant step in Ethereum’s rollup-centric roadmap, focusing on improving the network’s ability to handle high transaction volumes, reducing costs for layer-2 (L2) solutions, and optimizing validator operations. The key confirmed feature is **PeerDAS (Peer Data Availability Sampling, EIP-7594)**, which enhances data availability for L2 networks like Arbitrum, Optimism, and Base. Other potential features, such as Verkle Trees and certain Ethereum Improvement Proposals (EIPs), are under consideration but not yet confirmed for inclusion.

The timeline suggests:
- **Late September 2025**: Public testnets (e.g., Holesky) will begin testing Fusaka’s features, allowing developers and users to identify bugs and ensure stability.
- **Early November 2025**: The mainnet launch will activate Fusaka, implementing changes across Ethereum’s global network.

This upgrade builds on prior updates like **Dencun** (introduced blobs for L2 data) and **Pectra** (increased blob capacity and staking limits), aiming to make Ethereum more scalable, cost-effective, and developer-friendly.

Key Components of the #Fusaka Upgrade

X. **PeerDAS (Peer Data Availability Sampling, EIP-7594)**:
   - Allows validators to sample small portions of data “blobs” (large off-chain transaction data introduced in Dencun) instead of downloading entire datasets.
   - Increases blob capacity significantly, potentially from X to 36–48 blobs per block, enabling L2s to process more transactions at lower costs
   - Reduces bandwidth and hardware requirements for validators, improving efficiency.

X. Potential Gas Limit Increase (EIP-9678):
   - Proposes increasing the Layer X gas limit to XXX million units (a 4x increase), allowing ~6,000 transactions per block. This aims to boost L1 scalability but is still under consideration.

X. **Other EIPs Under Consideration**:
   - **EIP-7917 (Better Validator Coordination)**: Improves consensus stability by enabling deterministic proposer lookahead, letting validators know earlier who will propose blocks
   - EIP-7934: Caps RLP-encoded execution block size at XX MiB to enhance network stability and prevent denial-of-service risks.
   - **EIP-7951**: Introduces a precompiled contract for ECDSA signatures using the secp256r1 curve, improving compatibility with Web2 cryptography.
   - **EIP-7939**: Adds a new opcode (CLZ, Count Leading Zeros) to optimize smart contract performance.
   - **Verkle Trees**: Could replace Merkle-Patricia tries to reduce node storage needs, enabling “stateless clients” for lighter, more accessible validators (not yet confirmed).
