SOL news: Solana speeds up blocks by 17%, but transaction capacity stays the same
The change is the third SIMD-0525 stage and gives wallets and exchanges more frequent network updates while keeping Solana’s processing ceiling roughly unchanged.
- On Friday, Solana cut its target slot time from 300 milliseconds to 250 milliseconds, making the network's clock run nearly 17% faster in the third advancement of SIMD-0525.
- SIMD-0525 gradually reduces slot duration across staged phases, allowing Validators to assess network performance before each feature activation and preventing direct jumps to the final target.
- Under SIMD-0525, resource limits fall proportionally with slot duration; the 250ms configuration corresponds to a 37.5 million compute unit limit, down from the 60 million baseline.
- Users see faster transaction updates while Applications gain a more current network view; the fixed 432,000-slot Epoch duration now concludes in roughly 30 hours instead of 36 hours.
- Solana developers have not scheduled the final reduction, while The Alpenglow consensus redesign targets roughly 150ms finality to replace TowerBFT in a separate upgrade path.

Solana moves closer to 200ms slots after latest speed upgrade
Solana has cut its target slot time from 300 milliseconds to 250 milliseconds, increasing the rate at which the network produces slots by nearly 17% without raising its overall processing ceiling by the same amount. According to blockchain data, the…
SOL news: Solana speeds up blocks by 17%, but transaction capacity stays the same
The network is cutting its target slot time to 250 milliseconds, giving apps fresher blockchain data and validators shorter control windows while reducing the amount of work allowed in each slot.
Solana cuts the slot target time from 300 ms to 250 ms, accelerating the network by almost 17% without increasing the total transaction capacity
Solana Transaction Speed Rises Without More Capacity
TLDR Solana reduced its target slot time from 300 milliseconds to 250 milliseconds, making block production about 17% faster. The network now targets four slots per second, giving wallets and trading apps fresher transaction updates. Faster slots do not increase Solana’s overall processing capacity because each slot carries proportionally less work. Validators now control transaction [...]
