Ping

# 🕵️‍♀️ Ping

> **Ping lets you speak without being seen.**  
> A decentralized signalling platform where users can broadcast **verifiable messages anonymously** using **zero-knowledge proofs** on the **Status Network**.  

---



## 🌐 TL;DR

Ping is a **privacy-first social signalling protocol** where verified individuals can send **trustworthy signals like feedbacks/votes without revealing their identity**.  

It uses **Semaphore** for anonymous group proofs, **Mantle** for censorship-resistant verification, and **Buidl Guidl** tooling for seamless development and smart contract deployment.

> 💡 Think “verified whispers” — truthful, anonymous, and onchain.

---

## 🎯 Problem

Online spaces force a binary choice:
- **Anonymous = untrustworthy**  
- **Verified = exposed**

Communities, DAOs, and whistleblowers need a way to **prove they belong** without revealing **who they are**.

Traditional platforms rely on centralized trust — admins, servers, or moderators — introducing bias, risk, and censorship.

---

## 💡 Solution — *Ping*

Ping enables **verifiable anonymity** through zero-knowledge proofs.  
It allows anyone to post a **signal** (vote, opinion, alert) verified by math — not by trust.

- 🧠 **Zero-Knowledge Proofs** — users prove they’re group members without revealing their identity  
- 🔗 **Onchain Verification** — proofs verified by smart contracts on **Status Network**  
- 🔒 **Anonymous but Accountable** — one signal per identity, no duplicates or Sybil attacks  

---

## 🧩 How It Works

1. **Create a Ping Identity**
   - User generates a **Semaphore identity** (private key never leaves device).  

2. **Join a Group**
   - Group = community, company, or verified list.
   - Each group has an onchain group ID.

3. **Send a Ping**
   - User creates a **ZK proof** showing:
     - Membership in group ✅  
     - Unique signal nullifier 🆔  
   - Proof sent to the Ping smart contract.

4. **Verify & Broadcast**
   - Smart contract verifies the proof.  
   - Emits an event on Status Network → Ping frontend fetches it → signal displayed anonymously.
