Solana: Network clock moves to 350ms - 21 Aug 2026

Solana's clock moves from 400ms to 350ms in a protocol-wide change scheduled for the event window. The announcement describes it as the network's first speed-up since genesis, reducing the interval between blocks from the current 400 milliseconds.A shorter block interval can allow applications built on Solana to receive executed transactions more frequently, supporting faster network activity where applications can use the added cadence. The change affects the protocol's timing rather than adding a separate application feature.The update establishes faster network scheduling, but it does not by itself demonstrate broader application adoption or a measured change in user experience. Those effects depend on how applications and their users respond to the new block cadence.six years at 400ms. two days until 350.first time 's clock has ever moved.watch the heartbeat live:
