# Validator Node Types & Mining

Validator nodes are the trust anchor of Nubila’s network. They validate sensor data, achieve consensus, and ensure only accurate, verified signals are anchored on-chain. To balance decentralization, security, and accessibility, Nubila offers three tiers of validator nodes — each with distinct roles, entry costs, and reward levels.

#### Node Tiers

☀️ Sunny Nodes

* Role: Finalize consensus, secure high-frequency data streams, and guarantee oracle-grade reliability.
* Requirements: Highest cost and responsibility.
* Rewards: Largest daily output and one-time pre-TGE airdrop, reflecting their critical role in settlement security.<br>

🌧 Rainy Nodes

* Role: Provide redundancy, cross-check results, and strengthen consensus across regions.
* Requirements: Moderate cost with balanced workload.
* Rewards: Medium daily output and pre-TGE airdrop, ideal for participants who want deeper involvement without heavy infrastructure.<br>

🌥 Cloud Nodes

* Role: Expand network coverage and run basic validations like CID checks and metadata verification.
* Requirements: Lowest cost; can be run by anyone via browser or lightweight client.
* Rewards: Smaller daily output, but crucial for decentralization and accessibility.\

***Note: Validator node mining will officially begin after the TGE — rewards only start once the network goes live.***

**Node Airdrop Mechanism**

Only nodes purchased before the Token Generation Event (TGE) will receive an one-time airdrop reward.

* After receiving the airdrop, $sNUBI will follow the conversion process outlined in the next section.
