Solana (SOL) saw a successful mainnet upgrade on Friday morning that cuts the network's target slot time to 350 milliseconds (ms), down 50 ms from its former target of 400 ms.
Key facts
- Solana (SOL) saw a successful mainnet upgrade on Friday morning that cuts the network's target slot time to 350 milliseconds (ms), down 50 ms from its former target of 400 ms
- The change was the first step under SIMD-0525, a Solana upgrade proposal merged on May 14 that outlines a path to eventually cutting the target slot time to 200 ms, half its longtime value
- The change also shortens Solana's epochs, which each contain 432,000 slots, meaning an epoch that used to take about 48 hours should now only take about 42 hours
- In a point-in-time check conducted for this article, a 1,000-slot period shortly before the change took 415 seconds, compared with 368 seconds for a 1,000-slot period later in epoch 1020
Summary
The change was the first step under SIMD-0525, a Solana upgrade proposal merged on May 14 that outlines a path to eventually cutting the target slot time to 200 ms, half its longtime value. "Shorter slots reduce confirmation and finalization latency for users," the proposal explains. The change also shortens Solana's epochs, which each contain 432,000 slots, meaning an epoch that used to take about 48 hours should now only take about 42 hours. Solana developers plan to make three further 50 ms cuts until the slot time reaches its final target of 200 ms.
