# Validator Model

Validators in Tetreum are described as approved entities that run full nodes and sign blocks using secure private keys.

## Validator responsibilities

* Produce and sign new blocks
* Verify transactions and contract execution
* Maintain network uptime and integrity

The whitepaper also mentions validator rotation and slashing mechanisms as tools intended to preserve reliability across testnet and future mainnet environments.
