# 1. Protocol Mechanics & Yield Framework

### Blind Box Mechanics, Probability & Yield Model

#### Core Mechanism

Users purchase Blind Boxes using **USDC** and receive **Agri NFTs** with embedded computing power.\
These NFTs are directly connected to SpaceAgri’s **cloud mining pool**, producing **PTS**.

* Blind Box purchases are **cumulative**
* Total purchase amount determines the **matched device tier**
* Yield is calculated based on the corresponding **AgriPod hardware class**

#### Blind Box Pricing & Rarity Distribution

| Blind Box Type | Price (USDC) | N (Common) | A (Rare) | S (Epic) | SS (Legendary) |
| -------------- | ------------ | ---------- | -------- | -------- | -------------- |
| SeedBox        | 9.9          | 94.55%     | 5%       | 0.3%     | 0.15%          |
| SproutBox      | 99           | 38%        | 56%      | 5%       | 1%             |
| PrimeBox       | 299          | 0%         | 55%      | 40%      | 5%             |

#### Yield Estimation & Reference Model

**Computing Power Matching Rule**

During the campaign period, users’ **total Blind Box spending** is matched against the price tiers of official **AgriPod hardware devices**.

Once the cumulative amount reaches a specific tier, the user is considered to participate in yield generation at that tier.

**PTS Valuation Assumption**

* Blind Box output is calculated using a reference price of\
  **1 PTS = 0.1 USDC**

**Estimated Daily Yield Rate**

Based on real hardware production benchmarks, the estimated **static daily return** after reaching each tier is approximately:

* **0.5% – 1.0% per day**

| Cumulative Spend (Reference) | Device Tier | Daily PTS Output | Daily Value (0.1 USDC / PTS) | Estimated Daily Yield |
| ---------------------------- | ----------- | ---------------- | ---------------------------- | --------------------- |
| $750                         | AgriPod     | 37.5 PTS         | $3.75                        | \~0.5%                |
| $1,500                       | AgriPod Pro | 112.5 PTS        | $11.25                       | \~0.75%               |
| $3,000                       | AgriPod Max | 300 PTS          | $30                          | \~1.0%                |

### AgriPod Hardware Yield & Delivery Process

#### Yield During Bonus Acceleration Season

During the **SPAG & PTS Bonus Acceleration Season**\
\&#xNAN;**(2026-01-05 00:00 – 2026-01-26 00:00 UTC)**:

* **AgriPod ($750):** 37.5 PTS / day
* **AgriPod Pro ($1,500):** 112.5 PTS / day
* **AgriPod Max ($3,000):** 300 PTS / day

> Device computing power is included in the **global network hash rate**, which affects post-event settlement weight.

#### Device Architecture

* **AgriPod is a DePIN physical node**
  * Sensors, control system, AI growth models
  * Collects temperature, humidity, lighting, nutrient solution, growth metrics
  * Data is recorded on-chain
* **Dual-Pod Architecture**
  * **Physical pod at user location**
  * **Cloud cultivation pod cluster**
    * Local data accumulation
    * Cloud-side participation in scaled validation and commercial farming
    * Shared RWA revenue distribution and protocol incentives

#### Hardware Delivery Process

1. **Order & Information Confirmation**\
   Select device model → Submit shipping information
2. **Production Scheduling & Dispatch**\
   Order enters production / inventory queue → Shipping label generated
3. **Logistics & Delivery**\
   International or local shipping → User receives device
4. **Device Binding & Node Activation**\
   Bind wallet and device via App / Website → Device goes online as a node\
   (data upload + on-chain recording)
5. **Dual-Pod Activation**\
   Physical pod begins cultivation and data contribution\
   Cloud pod joins cluster tasks, validation, and rights allocation

### PTS → SPAG Conversion Mechanism

#### Conversion Rules

* **Conversion window:** 180 days
* **PTS can only be converted to SPAG within the window**
* Each conversion **burns the corresponding amount of PTS**, forming a deflationary loop

#### Time-Based Conversion Multiplier (Example Curve)

| Holding Duration | Conversion Multiplier |
| ---------------- | --------------------- |
| Day 1            | 0                     |
| Day 7            | 0.5x                  |
| Day 15           | 1.0x                  |
| Day 30           | 2.0×                  |
| Day 60           | 3.0×                  |
| Day 90           | 4.0×                  |
| Day 120          | 6.0×                  |
| Day 150          | 8.0×                  |
| Day 180          | 10× (Cap)             |

> The longer PTS is held, the more SPAG each unit can be converted into.\
> Participants may freely choose between **early liquidity** or **time-amplified conversion**, depending on individual strategy.
