Alpenglow Community Cluster Setup Instructions

The Alpenglow community cluster is ready for validators to join! The cluster is currently waiting for super majority to start. Validators will likely join over the next few days. If you are not part of the gensis set, we can delegate to your validator afterwards.

Operators should do the following to join the cluster:

  1. Checkout the alpenglow branch from Ashwin’s github:
git clone https://github.com/AshwinSekar/solana.git agave
cd agave

Solana 1.9.x Release Overview For Validators

The new 1.9.x release will be landing in mainnet soon. Here are some important new features to be aware of for validators:

1. Incremental snapshots

Snapshot size has become very large (On the order of 20 to 30GB to get a validator up and running). This change creates smaller incremental snapshots. Important: Once a validator starts using incremental snapshots, it cannot go back to version 1.8.

Recommended Upgrade Procedure:
