Solana’s current slot times sit at roughly 400 milliseconds. Anza, the engineering firm behind the network’s Agave validator client, wants to cut that number in half.
Anza CEO Brennan Watt has been discussing plans for 200-millisecond slot times as part of the upcoming Agave v4.2 upgrade, which he describes as a major client-level overhaul.
What 200ms slots actually mean
Think of a slot like a metronome tick for the blockchain. Every tick, the network has a chance to produce a new block. The faster the tick, the faster transactions get processed and confirmed.
At 400ms per slot, Solana already processes blocks significantly faster than most competitors. Ethereum, for context, operates on 12-second slots. Cutting Solana’s slot time to 200ms would make the network’s rhythm twice as fast, meaning transactions could theoretically be included in blocks and begin confirmation in half the current time.
