important notes
- The Ethereum Layer-2 solution has upgraded its capacity after successfully migrating from op-geth to op-reth client infrastructure.
- Network execution speed remains the primary scaling constraint and must be resolved before higher throughput goals can be achieved.
- Plans include reaching 400-500 Mgas/s by early 2026 with the implementation of TrieDB, which significantly speeds up state retrieval.
Base founder Jesse Pollack announced on November 6 that the network's gas limit has increased from 100 million gas per second to 125 million gas per second. The increased capacity brings Ethereum Layer 2 closer to its declared year-end goal of 150 Mgas/s.

Base published an engineering blog post on October 28 outlining its scaling roadmap. The post was written by engineer Anika Raghuvanshi, who pledged to double the network's gas limit from 75 Megagas/second to 150 Megagas/second by the end of 2025.
Significant capacity increase with migration to Reth Client
Networks have completed the transition from op-geth to op-reth client software in recent months. According to Engineering Post, Base just recently migrated its sequencer nodes to Reth.
The team measured that the Reth client performed significantly better than the previous op-geth client. Base currently recommends that external validators use Reth as their default client going forward.
Execution speed identified as the main bottleneck
Base has identified client execution speed as its biggest scaling bottleneck today. The Base network will consider potential native token plans while addressing infrastructure constraints. The team previously addressed limitations around L1 data availability and fault-tolerant performance.
The engineering team built a benchmark tool that simulates block construction times at specified gas limits with various traffic patterns. This tool revealed certain performance constraints that need to be addressed before further scaling.
Future expansion plans target 400-500 Mgas/s
Basically, we have set a goal of 400-500 Mgas/s by early 2026. Goals vary by completing the TrieDB database project and implementing new resource metering tools.
TrieDB restructures the database format to speed up state retrieval. The team said the final version of the project is nearing completion and expects to deliver 8 to 10 times faster storage reads.

This scaling effort aims to keep transaction fees below 1 cent. The network reached a price of 5 cents during a period of high activity in June 2025. Recent introductions such as XSwap's token creation platform and Stripe's USDC subscription payments have further increased application activity on the network.
