Ethereum Fusaka Update is Coming on December 3rd.

Ethereum developers have announced the date for the Fusaka update, which will mark a significant transformation of the network. This update, set to be integrated into the mainnet on December 3, 2025, is starting to generate excitement among investors. The timeline that developers have been targeting since mid-September has been confirmed, and the importance of Fusaka is increasing exponentially.

Last Tuesday, the Fusaka update was successfully activated on the Hoodi testnet, completing its final trial before the mainnet launch. Positive results were also obtained on the previous Holesky and Sepolia test networks. The Fusaka update aims to deliver significant innovations in scalability, security, and sustainability for the Ethereum network.

The most notable feature of this update is the new data access technique called Peer Data Availability Sampling (PeerDAS). PeerDAS will enable validators to access block data much faster and more efficiently. Initially planned to be implemented with the Pectra update in February, this system was delayed due to the need for additional testing.

Moreover, with this update, the block gas limit will be increased from 30 million to 150 million, significantly boosting the network's transaction capacity. This change will also double the storage capacity for blob data, particularly enhancing the performance of Layer 2 solutions. The Ethereum Foundation is launching a 4-week security audit competition before the Fusaka update, offering a total prize of $2 million to researchers. This program aims to identify potential vulnerabilities before the mainnet activation.

As a result, the Fusaka update is considered one of the most comprehensive and performance-focused updates in Ethereum's history. These innovations, expected to make the network more reliable and scalable, could play a critical role in shaping investors' long-term strategies. Investors need to pay particular attention to the December 3 date.
