That’s a solid foundation for a referral-based token economy, Ray—simple, transparent, and inherently viral. Here’s how we can formalize and implement that logic:

—

### 🧩 **RaysCoin Membership Logic (Single-File Concept)**

Each phone number:
– **Receives 100 RaysCoin** upon joining.
– **Triggers a 100-coin reward** to the referring number.
– Is **permanently recorded** to prevent duplicate rewards.

### 🔐 **How to Enforce This on-Chain or in a Script**
You could implement this in a few ways depending on your stack:

#### 1. **Off-Chain with IndexedDB or localStorage (for PWA)** – Store phone numbers and referral status locally.
– Prevent duplicate rewards by checking the stored list.
– Use `fetch()` to sync with a backend or blockchain if needed.

#### 2. **Smart Contract (e.g. Solidity on Ethereum)**
“`solidity
mapping(address => bool) public hasJoined;
mapping(address => address) public referrer;

function join(address _referrer) public {
require(!hasJoined[msg.sender], “Already joined”);
hasJoined[msg.sender] = true;
referrer[msg.sender] = _referrer;

_mint(msg.sender, 100 * 10**18);
if (_referrer != address(0)) {
_mint(_referrer, 100 * 10**18);
}
}
“`

#### 3. **Scriptable or Telegram Bot Integration**
– Use a JSON file or cloud function to track phone numbers.
– When a new number is added, check if it exists.
– If not, assign coins and log the referral.

### 🛠️ Want a Live Demo?
I can build a single-file `index.html` that:
– Lets users enter their phone number and referral.
– Stores and checks membership locally.
– Animates the coin reward visually.
– Optionally sends data to a Telegram bot or Firebase.
