Sentry Nodes Explained

The Sentry Node is an observation node that monitors the Xai rollup protocol and if an incorrect block is proposed, it raises an alarm (by whatever means its operator chooses) so that others can intervene. The purpose of Sentry nodes is to solve the verifier’s dilemma.

Sentry nodes can be run on community members’ laptops, desktops or even on cloud instances. As long as the node is running, there is a probabilistic algorithm that determines if the node operator will receive a esXai token reward from the network. That algorithm can be increased by staking Xai.
