# rootSubscribe

## rootSubscribe — Subscribe to root slot updates

> Subscribe to receive notification anytime a new root is set by the validator. This method establishes a persistent WebSocket connection that will send real-time notifications whenever the validator updates the root slot. The root represents the most recent slot that has been finalized and committed to the ledger. This subscription is useful for tracking the overall progress of the blockchain and understanding when transactions become irreversibly confirmed.
