Jito Reveals Validator Requirements Ahead of Solana’s Alpenglow Upgrade
- Published
Jito issued validator guidance ahead of Solana’s Alpenglow upgrade and identified supported client versions for node operators. It also described how BAM will handle maintenance by falling back to the standard Jito-Agave Block Engine and turning off two features during that period.
Key claims & sources
What it means
Validator operators notice this immediately because the operating guidance names supported clients they need to run before Alpenglow. The stake and validator figures also show the scale of the BAM setup that already sits behind these requirements.
In practice, the maintenance change means BAM nodes will not keep using the usual BAM path for that period; they will fall back to the standard Jito-Agave Block Engine instead. Multi-Packet Processing and Dynamic Block Incentives will not be available during that time, even though the broader validator guidance remains in place.
