 ## Keybase
 
-Including a Keybase username allows client applications \(like the Solana
-Network Explorer\) to automatically pull in your validator public profile,
-including cryptographic proofs, brand identity, etc. To connect your validator
-pubkey with Keybase:
-
-1. Join [https://keybase.io/](https://keybase.io/) and complete the profile for your validator
-2. Add your validator **identity pubkey** to Keybase:
-
-   - Create an empty file on your local computer called `validator-<PUBKEY>`
-   - In Keybase, navigate to the Files section, and upload your pubkey file to
-
-     a `solana` subdirectory in your public folder: `/keybase/public/<KEYBASE_USERNAME>/solana`
-
-   - To check your pubkey, ensure you can successfully browse to
-
-     `https://keybase.pub/<KEYBASE_USERNAME>/solana/validator-<PUBKEY>`
-
-3. Add or update your `solana validator-info` with your Keybase username. The
-
-   CLI will verify the `validator-<PUBKEY>` file
+Previously Keybase was used by validators to provide their validator icon, however Keybase has sunset its service and thus is no longer supported. Some old validator info accounts will still contain keybase usernames this is reflected in the serialized data returend when querying these validator info accounts.
