# Bluwhale AI Nodes
Bluwhale's Nodes are verifier nodes which are core components of the Data Verification Module but become extremely important when training and inferring AI on accurate data sets. While AI faces the challenge of not distinguishing fake data in the Web2 world, Bluwhale has developed a ground-breaking approach to scaling AI on accurate data on the blockchain.
The Bluwhale network involves its community in owning and operating Verifier Nodes, which are lightweight and essential for maintaining the protocol's integrity and enhancing its trustworthiness, capabilities, and security. These nodes primarily verify Trusted Execution Environment (TEE) attestations on-chain, ensuring the reliability of the results and the privacy of user data in Bluwhale's AI protocol.
There are two types of Bluwhale nodes to decentralize the AI network
1. Master Nodes: Limited availability to 100,000 and limited timeframe to purchase from September 30th 10AM UTC until December 31st 11PM UTC
2. Common Nodes: Infinite availability and no limitation to quantity or timeframe for purchase starting December 1st, 10AM UTC
The main difference between those two nodes is that Master nodes can create a community of people running nodes together, boosting the group's rewards and earning multi-level referral rewards, while Common nodes have only 1/10th the emissions, a lower price tag, and no boosting or community referral capabilities.
Side-by-side Comparison of Master vs Common Nodes
\*Tier 88 is a secret tier designed for those who refer more than 1000 node purchases and unlocks community profit capabilities in their Master Nodes. That means if you own a Tier 88 node, you can earn 2% from the node operators running nodes in your community.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://bluwhale.gitbook.io/bluwhaleai/ai-nodes/bluwhale-ai-nodes.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
