Key Points:
- Activation Date: Fusaka will activate on December 3, 2025, at 21:49:11 UTC.

- PeerDAS Introduction: A new protocol for verifying blob data availability, improving scalability without compromising security.


- Blob Parameter Only Forks: These will gradually increase blob throughput after the main upgrade.

- Gas Limit Increase: The default gas limit will rise to 60 million, enhancing execution capacity.

- User Experience Improvements: New features like secp256r1 support for better hardware integration.


In-depth summary:
The Fusaka mainnet upgrade represents a significant leap in Ethereum’s scaling strategy, following the earlier Pectra upgrade. Scheduled for activation on December 3, 2025, at slot 13,164,544, this upgrade aims to enhance Layer 1 performance and user experience. A key feature of Fusaka is the introduction of PeerDAS (Peer Data Availability Sampling), which allows nodes to verify blob data availability through sampling rather than downloading entire blobs. This innovation is crucial for increasing blob throughput while maintaining Ethereum’s security and decentralization.
Fusaka also includes several optimizations across both the execution and consensus layers. Notably, it raises the default gas limit to 60 million, which is expected to improve transaction processing capacity. Additionally, the upgrade will implement Blob Parameter Only (BPO) forks to safely increase blob throughput, with planned adjustments to the per-block blob target and maximum limits. These changes are designed to support the growing demand for Layer 2 solutions and reduce transaction fees while ensuring data availability.
Moreover, Fusaka introduces several Ethereum Improvement Proposals (EIPs) that enhance user experience and operational efficiency. For instance, the addition of secp256r1 support allows for better integration with modern secure hardware, facilitating mainstream blockchain adoption. Overall, the Fusaka upgrade is a comprehensive effort to bolster Ethereum’s infrastructure, paving the way for future scalability and improved user interactions.
ELI5:
Fusaka is like a big upgrade for Ethereum that will make it faster and better at handling lots of data. It will start working on December 3, 2025. One cool new feature lets computers check if data is available without needing to download everything, which saves time and keeps things secure. There will also be changes to allow more transactions at once, making it cheaper for everyone to use Ethereum!
