# 2.3 Master Node Availability and Reward System

<br>

The sale of Master Nodes is structured into five tiers to ensure gradual distribution and maintain exclusivity.

* Tier Structure: The first nodes sold fall under Tier 1. Once a predetermined number of nodes is sold in Tier 1, the sale progresses to Tier 2, and so on, up to Tier 5.
* Reward Scaling: Tier 1 nodes offer the highest rewards, with subsequent tiers offering gradually reduced payouts. This structure incentivises early adoption and rewards initial participants.
* Consistent Rewards for Tier 1 Owners: Users who purchase nodes in Tier 1 will retain their reward levels, ensuring that early adopters receive long-term benefits.
