Ethereum Sets TPS Record Ahead of Fusaka Upgrade

Layer-2 activity, led by Lighter’s high TPS, pushed Ethereum to a new 32,950 TPS network throughput record.

Gas limit expansion to 60M and upcoming PeerDAS boost scalability, lowering costs and increasing data capacity.

Fusaka adds security upgrades and passkey support, enhancing network stability and enabling broader institutional use.

Ethereum reached a major throughput yesterday when its ecosystem hit 32,950 transactions per second, according to GrowThePie. This peak surpassed last week’s 31,000 record as the network prepared for the Fusaka upgrade scheduled for December 3, 2025, at 21:49 UTC. The rise involved Ethereum Layer-1, multiple Layer-2 solutions, and key activity from Lighter.

Record Throughput Driven by Layer-2 Activity

The new TPS high emerged as Lighter, an Ethereum-native perp DEX built on a zero-knowledge rollup, processed transactions at speeds in the thousands. This consistently exceeded Base, which usually averages 100 to 300 TPS

According to Arkham, the broader ecosystem continued to scale as the daily TPS average reached 325, up from about 250 at the start of the year. This growth occurred as zero-knowledge proofs gained more attention, with Vitalik Buterin frequently highlighting the technology.

Moreover, the increase aligned with Ethereum’s recent gas limit change. Validators raised the limit from 45 million to 60 million on November 25 after achieving majority approval. This shift doubled block capacity in a year and created room for lower fees and higher throughput on both L1 and L2 networks.

Fusaka Introduces PeerDAS and Infrastructure Updates

The Fusaka upgrade combined the Osaka execution layer and Fulu consensus layer to expand scalability and reduce resource demands. Coin Metrics noted that increased blob capacity would enhance data availability for rollups, improving their cost structure. Ethereum’s official announcement stated that PeerDAS could unlock up to 8x more data throughput by allowing nodes to hold only one-eighth of blob data.

The upgrade also introduced Blob-Parameter-Only forks, giving developers the ability to adjust blob capacity without full hard forks. These changes supported higher transaction volumes and reduced operational strain for node operators.

Security Adjustments and Passkey Integration

Fusaka included several security-focused enhancements. EIP-7918 linked blob fees to congestion, while a cap of 16,777,216 gas per transaction aimed to prevent denial-of-service risks. Additionally, native secp256r1 signature support allowed passkey-style authentication on Apple and Android devices

Sharplink CEO Joseph Charom described this addition as a significant step for broader institutional use, although analysts noted that market impact would depend on sustained Layer-2 growth rather than immediate price reactions.
