# Consensus

## Overview

* [Validator node](/run-a-sunrise-node/types/consensus/validator-node.md): This type of node participates in consensus by producing and voting on blocks.
* [Full consensus node](/run-a-sunrise-node/types/consensus/full-consensus-node.md): A sunrise-app Full node to sync blockchain history.

**Data Availability Layer**: In addition to standard consensus tasks, Validator Nodes on Sunrise are responsible for verifying data for the Data Availability (DA) layer. This requires running additional daemons alongside the main `sunrised` process. See the [validator documentation](/build/validators.md) for more details.
