What is a validator node?

A validator node is a special type of full node that participates in “consensus.” By participating in consensus, validator nodes become responsible for verifying, voting on, and maintaining a record of transactions. On the Babylon Mainnet version of the Radix Public Network, there is a maximum of 100 validator nodes at a time. These are selected based on the amount of stake XRD token holders have delegated to them. 

Validator nodes underpin the security of any blockchain or DLT network. That is why it is of vital importance to ensure that validator nodes remain both performant and trustworthy. 

For Radix, it is vitally important that you, as an XRD token holder, support the security of the network by selecting the best validators to stake to.
