When a user or entity registers their validator(s) with Stakehouse. The protocol is acting as an registrar to reconcile who owns the validator and keep track of the validators' rewards. In the Stakehouse ecosystem validators are represented by KNOTs. These Knots interact with the Beacon Chain (validator) and SLOT tokens (ownership rights) to fractionalize validator ownership and keep track of inflation rewards. KNOTs are how liquid validators are enabled.
