Ethereum’s Fusaka upgrade goes live, with lower fees

Ethereum’s second major upgrade of the year, Fusaka, has gone live, bringing increased data capacity, reduced transaction costs, and improved usability.

The upgrade has officially started live on the Ethereum mainnet at 21:49 UTC Wednesday at epoch 411392, with the main feature Peer Data Availability Sampling (PeerDAS), which provides significant scaling capabilities for Ethereum and Layer 2.

Earlier this week, the Ethereum Foundation announced the details thread via the Ethereum X account, breaking down what this means for users, developers, node operators, Layer-2 and rollups, and businesses.

The Ethereum Foundation stated that Fusaka brings Ethereum one step closer to providing “near-instant transactions,” with increased speed resulting in a more seamless user experience.

“Fusaka lays the foundation for ‘instant-feel’ user experiences. Foundational pre-confirmations enable reduced transaction latency — moving from minutes to milliseconds. Combined with lower transaction costs, this opens the door to a new level of usability.”

In terms of L2 and clusters, Fusaka will “unlock up to 8x data throughput” through PeerDAS, it added, as it creates a significantly more efficient way to process information online.

In layman’s terms, PeerDAS fragments entire blobs of bulk data into smaller cells. This results in nodes having to download and upload significantly less data, allowing them to process information faster and allowing L2 to interact more efficiently with the main Ethereum network.

“For rollups, this means cheaper blob fees and more room to grow (plus lower user fees). As long as the network is kept decentralized,” the Ethereum Foundation stated.

Analysts speculate that Fusaka could spark a revival of ETH

Given the multitude of hidden improvements that Fusaka will provide, the market is anticipating how the price of Ether (ETH) will react.
