Coinbase’s Base, an Ethereum Layer-2 network, is gearing up for a major performance overhaul. In a May 24, 2025 announcement, Base lead developer Jesse Pollak laid out aggressive targets to vastly outpace current layer-1 rivals.
The plan calls for sub-$0.01 transaction fees, 200 ms confirmation times and ultimately 1 million transactions per second (TPS) on Base.
In the near term Base will scale to “over 200 TPS,” while building toward its ultimate goal of 1,000,000 TPS. The roadmap emphasizes speed and cost: Pollak said the upgrades are designed to “reduce transaction confirmation times to 200 ms and keep network fees consistently under $0.01”.
FlashBlocks and Decentralization Roadmap
A centerpiece of the upgrade is the new FlashBlocks mechanism. FlashBlocks will create “preconfirmation blocks” that let users see near-instant results in under 200 ms.
In effect, FlashBlocks split each full block into sub-blocks: Base’s full block time remains 2 second
