Ethereum Team Sets Fusaka Launch Date

Ethereum developers have prepared for an upcoming evolution with the Fusaka update, slated for release on the mainnet by December 3, according to discussions during the ACDC #165 meeting. Before the mainnet activation, the update will undergo testing on various networks: Holesky on October 1, Sepolia on October 14, and Hoodi on October 28. Further details regarding the specific date, time, and epoch numbers for the update will be shared shortly.

What Enhancements Does Fusaka Promise?

The Fusaka update envisions significant strides in Ethereum’s scalability and security front. A key advancement involves Peer Data Availability Sampling, a process enabling validators to verify extensive data sets, or “blobs”, in segments rather than as complete downloads. This improvement aims to enhance the network by streamlining transactions and alleviating congestion. Additionally, an increase in blob capacity, expected to double post-update, is another anticipated benefit.

How Is Security Addressed Pre-Launch?

Recognizing the necessity for a secure transition, the Ethereum Foundation is proactively conducting a four-week-long bug bounty program offering up to $2 million for uncovering potential vulnerabilities. This initiative underscores a commitment to fortifying the update before its official deployment.

Alongside these enhancements, Fusaka will see the block gas limit raised from 30 million to 150 million units, greatly expanding the potential for block transactions. The Verkle Trees system will optimize data storage and minimize proof sizes, boosting efficiency. Performance adjustments in the Ethereum Virtual Machine (EVM) are also set to expedite smart contract processes.

In the wake of Fusaka, the Ethereum network’s roadmap foresees the Glamsterdam update, targeted for 2026. This update is poised to introduce the EVM Object Format (EOF) and shorten block times, consistently working towards enhanced capacity and transaction velocity.

Notable final outcomes of the Fusaka update are:

• Peer Data Availability Sampling for improved validation efficiency.
• Doubling of blob capacity, reducing network strain.
• Substantial enhancement to block gas limits allowing increased transaction volume.
• Optimization via Verkle Trees and improved storage efficacy.

Ethereum’s project lead shared insights into this major transition:

“The Fusaka update is another cornerstone in bolstering Ethereum’s infrastructure, setting the stage for scalable growth and sustained security.”
