Solana Completes SIMD-0525 Upgrade, Slashing Slot Time to 200ms
Solana has activated 200-millisecond slots on its mainnet, effectively doubling its block output capacity.
Solana has activated 200-millisecond slots on its mainnet, effectively doubling its block output capacity. Solana (SOL) is trading at $109.33, down 0.3% since this brief published. This is an original TLT brief synthesising 2 outlets (Bitcoin World, Crypto Daily), plus live market data, as of Sun, 11 Oct 2026 14:15:01 UTC.
The reduction in slot time from 400ms to 200ms enhances Solana's transaction throughput and efficiency, positioning it as a faster blockchain network. This upgrade is particularly significant ahead of the upcoming Alpenglow release, which aims to further optimize network performance.
- Solana's slot time reduced from 400ms to 200ms on October 9.
- Average slot time in first full epoch was 218.3ms.
- Upgrade aims to double network's transaction throughput capacity.
- Move positions Solana for upcoming Alpenglow release.
Both Bitcoin World and Crypto Daily report that Solana has successfully activated 200-millisecond slots on its mainnet as part of the SIMD-0525 upgrade, effectively cutting the target slot time in half from the original 400-millisecond configuration. While Bitcoin World emphasizes the completion of the upgrade, Crypto Daily provides additional detail on the first full epoch's performance, reporting an average slot time of 218.3 milliseconds. Both outlets agree on the core development and its significance for Solana's network capacity.
On October 9, 
Solana completed the SIMD-0525 upgrade, activating 200-millisecond slots on its mainnet. This change reduces the target slot time from the original 400-millisecond configuration, effectively doubling the network's block output capacity.
The upgrade is part of Solana's ongoing efforts to enhance its transaction throughput and network efficiency. The first full epoch after the upgrade averaged 218.3 milliseconds per slot, according to Crypto Daily.
This development is particularly significant as it sets the stage for the upcoming Alpenglow release, which aims to further optimize Solana's network performance. The reduction in slot time is expected to improve the network's ability to handle a higher volume of transactions.
Solana's mainnet has been operational with the new slot time since the upgrade's activation. The network's performance during this period will be closely monitored to ensure stability and to identify any potential issues.
In the current market context, with the total crypto market cap at $2.88 trillion and 
Bitcoin showing a modest 24-hour gain of 0.39%, Solana's price has remained relatively stable, currently trading at $109.61 with a 24-hour change of -0.05%.
Since this brief published about 31 hours ago, Solana (SOL) has moved from $109.61 to $109.33 — -0.26%.
The chart plots SOL's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
Over the past 24 hours SOL moved -0.4% while Bitcoin moved +0.3%. SOL has historically moved about 1.21× Bitcoin, implying roughly +0.4% today — so this is roughly what its usual link to Bitcoin would predict.

At today's peer-to-peer rate, 1 SOL ≈ ₦149,235.45 (about $109.33), down 0.4% over 24 hours. The naira itself trades about 2.6% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
