Solana Aims to Cut Block Time in Half, and You Can Watch It Live

Solana started halving its block time, taking the first step from 400 milliseconds down toward 200. The first cut lands at epoch 1020, one of the roughly two-day windows the network uses to schedule changes.

Anza's Agave software carries all four steps, and each one switches on separately. Solana will end up producing a new block every fifth of a second.

Solana Doubles Its Blocks Per Second

Today Solana makes about 144 blocks per minute, or roughly two and a half every second. At 200ms that rate doubles to 300 blocks a minute.

Faster does not mean bigger. Each block shrinks in step with the clock, so the network carries the same total load. Blocks simply arrive twice as often in smaller pieces.

The rollout runs in four steps of 50 milliseconds each. Validators can pause the sequence at any point if too many blocks start getting skipped. Anza has called its timetable tentative for that reason.

The live tracker at solana.com/200ms showed 96.7% of stake already running the required software. Meanwhile, 690 validators and 435 million SOL in active stake sat behind the upgrade.
