Ethereum Nears Fusaka Testnet Phase Preceding 2025 Mainnet Launch

Key Points:

  • Ethereum progresses with Fusaka upgrade; mainnet in 2025.
  • Increases block gas limit to 60M units.
  • PeerDAS enables efficient data handling for Ethereum.

Ethereum’s Fusaka upgrade is advancing to its final testnet phases before its December 2025 mainnet launch, introducing critical scalability and efficiency enhancements, according to ChainCatcher and Cointelegraph reports.

This upgrade promises to enhance Ethereum’s scalability and efficiency, potentially impacting Layer 2 networks and increasing user and institutional interest in Ethereum-based technologies.

Community Optimism Surrounding Fusaka’s Scalability Enhancements

The Fusaka upgrade, set to launch on October 28 on the Hoodi testnet, will revise Ethereum’s transaction capabilities by instituting a single transaction gas limit of around 16.78 million units. These changes aim to prevent any single transaction from dominating block processing.

Notable shifts include increasing Ethereum’s default gas limit to 60 million and deploying PeerDAS technology. This adjustment is anticipated to streamline how nodes handle data, reducing overhead while maintaining security and enhancing scalability.

Community and developer responses have been largely positive. Although specific endorsements or critiques from industry leaders like Vitalik Buterin aren’t documented, general sentiment on platforms like GitHub indicates optimism about Ethereum’s enhanced scalability and efficiency.
