Ethereum developers have successfully deployed the Fusaka upgrade on the Sepolia testnet, marking a significant step towards enhancing the network's scalability and efficiency. This deployment, which took just over 20 minutes, paves the way for the upgrade's eventual launch on the Ethereum mainnet, anticipated in early December.
Key Takeaways
-
Fusaka upgrade successfully deployed on Sepolia testnet.
-

-
Mainnet launch targeted for December 3.
-
Primary goal: enhance scalability and efficiency through PeerDAS protocol (EIP-7594).
-
PeerDAS expected to double network throughput.
Fusaka Deployment Progress
The successful deployment of Fusaka on the Sepolia testnet on October 14, 2025, was confirmed by prominent figures in the Ethereum community, including sassal.eth and abcoathup.eth. This milestone is crucial for validating the upgrade's functionality before its mainnet release.
The next critical step involves testing the upgrade on the Hoodi testnet, which is slated for October 28. Following a successful run on Hoodi, the hard fork is scheduled to go live on the Ethereum mainnet on December 3.
Enhancing Ethereum's Scalability
The primary objective of the Fusaka upgrade is to significantly improve Ethereum's scalability and overall efficiency. A cornerstone of this upgrade is the implementation of the PeerDAS protocol (EIP-7594).
This innovative protocol is projected to double the network's throughput. Vitalik Buterin, co-founder of Ethereum, has highlighted the unique nature of PeerDAS, explaining that it will enable nodes to verify block data availability without needing to download the entire dataset. Instead, nodes will process small data fragments and utilize erasure coding to reconstruct any missing information.
Increased Network Activity
In parallel with the upgrade developments, the Ethereum network has witnessed a surge in user activity. The number of unique stablecoin senders has reached an all-time high, surpassing one million addresses weekly. This represents a substantial increase from the average of around 400,000 weekly senders observed between January 2020 and July 2024.
Furthermore, the monthly active addresses have remained consistently high, fluctuating between 16 and 18 million over the past year. The creation of new addresses is also on a steady upward trend, with over 4.51 million new addresses recorded by the end of September, setting a 12-month record.
Recent news also includes the Kingdom of Bhutan's announcement of its decision to migrate its national ID system to the Ethereum blockchain, further underscoring the network's growing adoption and utility.
