Cosmos is a decentralized Proof of Stake protocol comprised of independent parallel blockchains. These chains are typically built using the Cosmos SDK, a middleware design framework with modular components, and interoperate by using the Inter-Blockchain Communication Protocol (under development).
We are intimately familiar with the Cosmos Protocol; we have been active community members and operated inside the Cosmos testnet for over a year before launch.

Types of Cosmos Nodes
Validator Node
Validators on the Cosmos protocol are full nodes that participate in consensus and vote on proposals via cryptographic signatures made by their private keys. Validators are required to vote on Cosmos Hub governance.
For successfully performing their work, validators are rewarded with ATOMS in the form of transaction fees and inflationary rewards. The more ATOMS that are bonded or delegated to a validator, the more they participate in consensus, and thus, the more they earn.
Sentry Node
In the Cosmos protocol, a validator runs the risk of a Distributed Denial of Service (DDoS) attack due to having a fixed IP address and a RESTful API port facing the Internet.
Sentry nodes are “messenger” full nodes that protect the validator by constantly relaying messages signed by the validator to the protocol. This prevents potential attackers from discovering the validator node itself, defending it against a DDoS attack.
