## Zentanode

Zentanode is decentralized mining hardware for offline connectivity. Operators power the Zentamesh network and earn 25 CHAIN tokens per month. Zentanodes provide offline communication within a 6km range and serve as gateways for the Zentamesh network. The Zentanode reward program will begin once node operations launch.
