Ethereum Fusaka Hard Fork Successfully Upgraded: PeerDAS Technology Drives Scalability Breakthrough

Ethereum Successfully Completes ‘Fusaka’ Upgrade: Lower Gas Fees, Faster Verification—A Potential Game Changer?

Ethereum has successfully completed its second major code upgrade of the year, the “Fusaka” hard fork. This upgrade is a technical initiative aimed at addressing core scalability issues in blockchain, focusing on improving high-volume transaction settlement speeds for Layer 2 networks and reducing the operational burden on validator nodes.

According to multiple industry media reports, the Fusaka upgrade was successfully triggered and finalized within about 15 minutes, with the network stably accepting the updated code. Leading Ethereum core developers witnessed the successful upgrade together on a live streaming channel.

The core of this upgrade is the introduction of the “PeerDAS” technology. PeerDAS is a system that allows validators to check only fragments of data instead of verifying all data in bulk at once, thus completing validation with fewer computing resources. As a result, the efficiency of processing large-scale data “blobs” submitted by Layer 2 networks is improved, network congestion is expected to ease, and gas fees are likely to decrease.

Currently, most Layer 2s submit transaction data to the Ethereum mainnet in the form of blobs, requiring validators to download and review all this data. This process places a heavy load on the network, but with the introduction of PeerDAS, validators only need to check part of the blob, speeding up processing and reducing costs.

The upgrade is expected to be especially beneficial to small-scale validators or new node operators. For individuals or small and medium operators with limited resources, the entry barrier will be lower. However, for institutions like large staking pools that operate multiple nodes, the relative impact may be limited.

According to a core Ethereum Foundation developer, there are plans to gradually increase the number of blobs to verify whether the network can securely handle increased throughput. This suggests a series of incremental changes over the coming months.

The Fusaka upgrade is a dual hard fork affecting both the execution and consensus layers, with its name derived from “Fulu” and “Osaka.” The execution layer is where transactions and smart contract executions occur, while the consensus layer is responsible for validating and finalizing these operations.

One core developer noted that due to the importance of PeerDAS, more complex features were excluded from this upgrade, and any projects likely to cause delays were decisively left out. This upgrade demonstrates Ethereum’s determination to boost mainnet processing speed.

In addition to PeerDAS, the upgrade includes a total of 13 EIPs (Ethereum Improvement Proposals). These cover areas such as simplification of network message structures, prevention of excessive computation and transaction size limits, gas fee adjustments, enhanced blob handling stability, improved smart contract computation efficiency, and improvements to the developer environment and overall network efficiency.

Traditional financial institutions are also paying attention to this upgrade. A digital asset company recently rated Fusaka as “a decisive step aligned with Ethereum’s strategic roadmap” in its report, analyzing that mainnet improvements can boost market confidence.

Meanwhile, the Ethereum development team is also discussing the next major upgrade, “Glamsterdam,” but the specific timeline and contents have yet to be determined.
