This flowchart illustrates how Builders request capacity and provide ICNT tokens, which are collected in the Treasury.
***
## How Access to Network Resources are Calculated
* Capacity Request: Builders submit a request specifying:
* Storage amount (e.g., 1PB).
* Location (Cluster)
* Duration of required storage.
* Pre-Assignment and Price Calculation:
* Cluster Price: The price within a cluster is determined based on HP reservation prices
* Max Cluster Price: A cap to ensure that pricing within clusters remains fair and accessible.
* Final ICNT Requirement Calculation:
* After pre-assignment, the ICN protocol calculates the total ICNT requirement that an Builders must provide, factoring in the protocol margin.
* Formula:\
\
$$\text{ICNT Requirement} = (1 + \text{Protocol Margin}) \times \text{Cluster Price} \times \text{Booked Capacity} \times \text{Period}$$
* where:
* Cluster Price is the rate per TB per month
* Booked Capacity is the amount of storage requested (in TB)
* Period is the number of months the storage is needed
* Protocol Margin is a percentage retained by the protocol (e.g., 25%) to keep the network sustainability and maintenance.\
\
**Example**: If a Builder requests 1 PB of storage for 1 month and the selected Cluster Price is 2.8 ICNT per TB per month, with a Protocol Margin of 25%, the final ICNT access requirement will be:\
\
$$\text (1 + 0.25) \times 2.8 \times 1,000 \times 1 = {3,500 ICNT}$$

## Distribution of Builders ICNT Access Requirements
The ICNT provided by Builders is collected in the Treasury. Allocations from the Treasury to various parts of the network are determined by governance decisions to ensure the network's smooth operation and adaptability:
* **Reward Reserve**: Based on governance decisions, a portion of the ICNT incoming to the Treasury are reallocated to the Reward Reserve. This reserve is responsible for distributing ICNT rewards to Hardware Providers (HPs) and HyperNodes for their services.
* **Protocol Treasury**: Another portion of the ICNT, as decided by governance, is allocated to the Protocol Treasury. This allocation supports network upkeep, development, and future use cases.
