# Robonode

Robonode is what we call an autonomous VM in a Trusted Execution Environment that holds the biometric data of the validators.

It is not accessible to external operators or local administrators and is designed to secure biometric data in such a way that they can not be extracted, viewed, or compromised in any other way.

## Robonode Swap

We will occasionally perform a scheduled robonode swap, which means that all the validators have to re-enroll and re-authenticate. We will announce this in advance.

If you have lost your private key after you have enrolled and can no longer access the network - this is your chance to enroll with a new key.
