EIP 7825: The Overlooked Upgrade Enabling 100x Ethereum Scaling in the ZK Era

Source: CryptoNewsNet Original Title: This EIP Brings 100x Scaling to Ethereum Original Link: Ethereum (ETH), the biggest smart contracts platform, successfully activated its Fulu-Osaka (Fusaka) hard fork. With all eyes on Peer Data Availability Sampling (PeerDAS) optimization, EIP 7825 “Transaction Gas Limit Cap” might be terribly overlooked. Here is why it is extremely important for Ethereum (ETH) to remain scalable in the ZK era.

EIP 7825 Makes Ethereum (ETH) Scalable, Predictable, Performant

EIP 7825 is one of the most underrated upgrades for the future of ZK proving and 100X Ethereum scaling, according to industry experts. It mitigates the risks of a single “mega-transaction” eating the entire computational capacity of an Ethereum (ETH) block.

EIP 7825 imposes a per-transaction gas ceiling of 30 million gas — no Ethereum (ETH) transaction can spend more gas to be verified. Before Fusaka, large transactions could be consuming too many resources, increasing potential latency.

This was also dangerous for ZK proving as no zero-knowledge system was able to predict how Ethereum (ETH) would process this “unparallellized unit of work.” This, in turn, was removing the opportunity for real-time proving of transactions on Ethereum (ETH), which was totally unacceptable for “100X Ethereum scaling” ambitions.

But now, when the gas spending per block is predictable and bounded for single transactions, ZK proving systems become more predictable as well. In the worst-case scenario with a maximum post-Fusaka transaction, the entire procedure of proving will not take more than five seconds.

As a result, with relevant parallel computing power, ZK systems are already able to regularly verify 100-200 million gas blocks, which is totally aligned with real-time proving goals of ZK road maps for Ethereum (ETH).

Fusaka Activation Went Smoothly Despite Bug

Ethereum (ETH) Fusaka upgrade was activated as predicted, on Dec. 3, 2025. It revamped data logistics and increased the number of blobs Ethereum (ETH) can handle in every block.

Despite the bug found in Prysm, the upgrade was activated exactly as intended, with Lighthouse becoming the dominating client. As researchers notice, the process of activation caused zero downtime and reinforced the necessity of client diversity.
