SOL news: Solana is about to halve its block times as final 200-millisecond upgrade nears
Solana is scheduled to reduce its target block time from 250 to 200 milliseconds at epoch 1053 on Friday, completing a phased cut from the original 400 milliseconds. The change creates five block-production opportunities per second, while lowering each block’s compute limit so theoretical processing capacity remains roughly unchanged. Faster slots may provide applications with more frequent updates and reduce transaction delays and some opportunities for ordering exploitation. The change also increases validator voting costs and network demands, and shortens the time available for transactions using recent blockhashes. The upgrade is already deployed on testnet and devnet; mainnet timing depends on network conditions, including missed block opportunities.
