Solana Mainnet is switching to Alpenglow, Solana's new consensus protocol (SIMD-0326). The Solana developers at Anza plan to turn it on Wednesday, October 21, around 14:50 UTC.
**What this means for you** - This change applies to Solana Mainnet. Testnet and Devnet already run Alpenglow and are not affected. - The network may be briefly unstable while the switch-over happens. - Your Quicknode Solana endpoints stay the same. You don't need to change anything.
**What we're doing** - Our Solana Mainnet infrastructure already runs Agave v4.3.0. - We're pausing all planned maintenance on Solana Mainnet during the upgrade window. - Our team will actively monitor the network during and after the switch-over, and we'll post updates here if we see any impact.
**Try Alpenglow now** If you want to check how your application behaves under Alpenglow before it reaches Mainnet, it's already live on Solana Testnet and Devnet.
