A danger in the Cosmos protocol is that a validator node can be attacked using the Distributed Denial of Service method. The validator node has a fixed IP address and it opens a RESTful API port facing the Internet. Sentry nodes are “messenger” full nodes that protect the validator by constantly relaying the validator’s signed messages to the network. This prevents the attacker from discovering the validator node and makes defending against DDoS easier.
