# Base Layers Compete on Finality Speed

Major base layers will keep redesigning consensus and block propagation to cut settlement latency for payments and exchange flows, which forces a recurring trade-off between speed and validator geographic dispersion that shapes where stablecoin and trading activity settles.

## Recent evidence

- [confirms] Solana Switches From TowerBFT to Alpenglow, Targeting 150-Millisecond Finality (2026-10-22): Solana's Alpenglow activation targets 150ms finality, and on the same day Ethereum researchers published a design for broadcasting large blocks faster. Both of the largest smart-contract base layers are working on settlement latency at once, which makes the speed race a pattern across chains rather than one chain's roadmap.
