# RangerBlock Secure Communication Contracts Plan
|
||||
|
||||
## CODENAME: SENTINEL COMMS PROTOCOL
|
||||
|
||||
**Author**: David Keane (IrishRanger) + Claude Code (Ranger)
|
||||
**Date**: 2025-12-04
|
||||
**Status**: PLANNING
|
||||
**Classification**: PRIVATE
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
Smart contracts for secure, identity-verified communication channels. These contracts ensure users are **99.99% certain** they're communicating with the intended person through cryptographic identity verification.
|
||||
|
||||
### The Problem
|
||||
|
||||
In regular chat apps:
|
||||
- Anyone can pretend to be someone else
|
||||
- Man-in-the-middle attacks possible
|
||||
- No proof of who you're really talking to
|
||||
- Impersonation is easy
|
||||
|
||||
### The Solution
|
||||
|
||||
**Blockchain-verified identity handshakes** before sensitive communications:
|
||||
1. Both parties prove identity via on-chain signatures
|
||||
2. Challenge-response authentication
|
||||
3. Session keys derived from verified identities
|
||||
4. Immutable audit trail of who talked to whom
|
||||

|
||||
|
||||
## Three Communication Contracts
|
||||
|
||||
### 1. RangerTextChat Contract (WHISPER PROTOCOL)
|
||||
|
||||
**Purpose**: Secure text messaging with identity verification
|
||||
|
||||
```
|
||||
Flow:
|
||||
1. Alice wants to chat with Bob
|
||||
2. Alice creates ChatSession request on-chain
|
||||
3. Bob sees request, verifies Alice's on-chain identity
|
||||
4. Bob accepts with signature proving he's real Bob
|
||||
5. Both derive shared session key
|
||||
6. E2E encrypted text chat begins
|
||||
7. Session recorded on blockchain (not content!)
|
||||
```
|
||||
|
||||
**Features**:
|
||||
- Identity verification before first message
|
||||
- E2E encryption with verified keys
|
||||
- Session expiry (configurable)
|
||||
- Block/report with on-chain evidence
|
||||
- Message receipts (delivered/read) optional
|
||||
|
||||
**Contract Data**:
|
||||
```rust
|
||||
struct TextChatSession {
|
||||
session_id: [u8; 32],
|
||||
initiator_id_hash: [u8; 32],
|
||||
responder_id_hash: [u8; 32],
|
||||
initiator_pubkey: [u8; 32], // For E2E encryption
|
||||
responder_pubkey: [u8; 32],
|
||||
created_at: i64,
|
||||
expires_at: i64,
|
||||
status: SessionStatus, // Pending/Active/Ended/Blocked
|
||||
initiator_signature: [u8; 64],
|
||||
responder_signature: [u8; 64],
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. RangerVoiceChat Contract (ECHO PROTOCOL)
|
||||
|
||||
**Purpose**: Secure voice calls with identity verification
|
||||
|
||||
```
|
||||
Flow:
|
||||
1. Alice initiates voice call to Bob
|
||||
2. Contract creates VoiceSession with Alice's signature
|
||||
3. Bob receives call notification
|
||||
4. Bob verifies Alice's on-chain identity
|
||||
5. Bob answers with his signature
|
||||
6. DTLS/SRTP keys exchanged using verified identities
|
||||
7. Encrypted voice call begins
|
||||
8. Call metadata recorded (duration, not content)
|
||||
```
|
||||
|
||||
**Features**:
|
||||
- Pre-call identity verification
|
||||
- Secure key exchange
|
||||
- Call duration tracking
|
||||

|
||||
|
||||
**Contract Data**:
|
||||
```rust
|
||||
struct VoiceCallSession {
|
||||
call_id: [u8; 32],
|
||||
caller_id_hash: [u8; 32],
|
||||
callee_id_hash: [u8; 32],
|
||||
caller_signature: [u8; 64],
|
||||
callee_signature: [u8; 64],
|
||||
call_started: i64,
|
||||
call_ended: i64,
|
||||

|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 3. RangerVideoChat Contract (VISION PROTOCOL)
|
||||
|
||||
**Purpose**: Secure video calls with identity verification
|
||||
|
||||
```
|
||||
Flow:
|
||||
1. Alice initiates video call to Bob
|
||||
2. Contract creates VideoSession with Alice's signature
|
||||
3. Bob receives notification + Alice's verified identity
|
||||
4. Bob can see Alice's on-chain profile before answering
|
||||
5. Bob answers with signature proving identity
|
||||
6. WebRTC connection established with verified DTLS fingerprints
|
||||
7. Encrypted video call begins
|
||||
8. Call metadata recorded on-chain
|
||||
```

|
||||
- Screen sharing flag
|
||||

|
||||
|
||||
**Contract Data**:
|
||||

||||
callee_signature: [u8; 64],
|
||||
call_started: i64,
|
||||
call_ended: i64,
|
||||
duration_seconds: u64,
|
||||

|
||||
// Video-specific
|
||||
screen_shared: bool,
|
||||

## Identity Verification Flow (All Contracts)
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────────┐
|
||||
│ IDENTITY VERIFICATION │
|
||||
├─────────────────────────────────────────────────────────────┤
|
||||
│ │
|
||||
│ 1. CHECK ON-CHAIN REGISTRATION │
|
||||
│ └─> User must have RangerRegistration approved │
|
||||
│ │
|
||||
│ 2. CHALLENGE-RESPONSE │
|
||||
│ └─> Contract generates random nonce │
|
||||
│ └─> User signs nonce with private key │
|
||||
│ └─> Contract verifies signature matches on-chain pubkey │
|
||||
│ │
|
||||
│ 3. HARDWARE BINDING (Optional Extra Security) │
|
||||
│ └─> Include hardware fingerprint in signature │
|
||||
│ └─> Prevents key theft (key only works on original HW) │
|
||||
│ │
|
||||
│ 4. SESSION ESTABLISHMENT │
|
||||
│ └─> Both parties verified │
|
||||
│ └─> Session keys derived │
|
||||
│ └─> Communication begins │
|
||||
│ │
|
||||
└─────────────────────────────────────────────────────────────┘

## Why 99.99% Certainty?
|
||||
|
||||
| Security Layer | What It Proves |
|
||||
|----------------|----------------|
|
||||
| On-chain registration | User went through registration process |
|
||||
| Hardware ID binding | Using the same physical device |
|
||||
| RSA signature | Has the private key (not just username) |
|
||||
| Challenge-response | Key is available NOW (not stolen earlier) |
|
||||
| Session signature | Both parties actively participating |
|
||||
|
||||
**The 0.01%**:
|
||||
- Physical device theft + password compromise
|
||||
- Quantum computer breaking RSA (future concern)
|
||||
- Zero-day in cryptographic libraries
