+# Campaign KYC and Verification System - Design & Implementation
+
+## Executive Summary
+
+This document provides a complete design and implementation specification for Shade Protocol's Campaign KYC (Know Your Customer) and Verification System. The system enables robust verification workflows for campaign creators and backers with comprehensive security, event logging, and storage optimization.
+
+## Architecture Overview
+
+### Core Components
+
+The KYC system is implemented as a modular component within the Shade Protocol:
+
+- **types.rs**: Data structures (KycRequest, CampaignKycStatus, BackerKycStatus, VerificationStatus, VerificationType)
+- **kyc_v2.rs**: Core verification logic (16+ public functions)
+- **events.rs**: Event definitions (8 event types)
+- **interface.rs**: Public ShadeTrait interface (24 functions)
+
+### Data Model
+
+#### KycRequest
+```rust
+pub struct KycRequest {
+    pub id: u64,                              // Unique request ID
+    pub subject: Address,                     // User being verified
+    pub verification_type: VerificationType,  // Individual, CampaignCreator, or Backer
+    pub submitted_at: u64,                    // Request timestamp
+    pub reviewed_at: u64,                     // Review completion timestamp
+    pub reviewer: Address,                    // Reviewer's address
+    pub status: VerificationStatus,           // Unverified → Pending → Approved/Rejected/Suspended
+    pub document_count: u32,                  // Number of documents submitted
+    pub metadata: String,                     // Custom metadata
+}
+```
+
+#### CampaignKycStatus
+```rust
+pub struct CampaignKycStatus {
+    pub campaign_id: u64,                     // Campaign ID
+    pub creator: Address,                     // Campaign creator
+    pub kyc_status: VerificationStatus,       // Campaign creator's KYC status
+    pub min_backer_kyc_required: bool,        // Whether backers must be KYC'd
+    pub created_at: u64,                      // Campaign creation timestamp
+    pub verified_at: u64,                     // Campaign approval timestamp
+    pub verified_by: Address,                 // Reviewer who verified
+}
+```
+
+#### BackerKycStatus
+```rust
+pub struct BackerKycStatus {
+    pub backer: Address,                      // Backer address
+    pub kyc_status: VerificationStatus,       // Current KYC status
+    pub campaigns_backed: u64,                // Total campaigns backed
+    pub total_backed_amount: i128,            // Total funds contributed
+    pub last_kyc_check: u64,                  // Last KYC verification timestamp
+}
+```
+
+## Verification Workflow
+
+### Phase 1: User Submission
+1. User calls `submit_kyc_verification(subject, type, metadata)`
+2. Request stored with Pending status
+3. Added to pending queue
+4. Event emitted: `KycRequestSubmittedEvent`
+
+### Phase 2: Reviewer Approval
+1. Reviewer calls `approve_kyc_request(request_id, expiration_days)`
+2. Status updated to Approved
+3. Expiration date set: now + (days * 86400)
+4. Added to approved list
+5. Event emitted: `KycRequestApprovedEvent`
+
+### Phase 3: Campaign Use
+1. Creator with approved KYC registers campaign
+2. Campaign pending until reviewer verification
+3. Reviewer calls `verify_campaign(campaign_id)`
+4. Campaign now eligible for funding
+5. Event emitted: `CampaignKycVerifiedEvent`
+
+### Phase 4: Compliance
+1. If compliance issue discovered
+2. Reviewer calls `suspend_kyc(subject, reason)`
+3. User loses verification status
+4. Event emitted: `KycSuspendedEvent`
+
+## Security Considerations
+
+### Authentication
+- All user operations require `require_auth()`
+- Admin operations verified via `core::assert_admin()`
+- Reviewer operations verified via role check
+
+### Authorization
+- Role-based access control (Admin > Reviewer > User)
+- No self-approval possible
+- Each role has specific capabilities
+
+### Reentrancy Protection
+- Guards on all state mutations
+- Prevents concurrent state changes
+- Atomic operations for ID generation
+
+### Compliance
+- Expiration validation at read-time
+- Suspension capability for legal requirements
+- Comprehensive event logging for audit trail
+
+## Events Schema
+
+| Event | Fields | Purpose |
+|-------|--------|---------|
+| KycRequestSubmittedEvent | request_id, subject, verification_type, timestamp | Track submissions |
+| KycRequestApprovedEvent | request_id, subject, reviewer, expiration_date, timestamp | Record approvals |
+| KycRequestRejectedEvent | request_id, subject, reviewer, reason, timestamp | Track rejections |
+| KycSuspendedEvent | subject, reviewer, reason, timestamp | Compliance alerts |
+| CampaignKycRegisteredEvent | campaign_id, creator, require_backer_kyc, timestamp | Campaign onboarding |
+| CampaignKycVerifiedEvent | campaign_id, creator, reviewer, timestamp | Campaign activation |
+| KycReviewerRoleGrantedEvent | admin, reviewer, timestamp | Access control audit |
+| KycReviewerRoleRevokedEvent | admin, reviewer, timestamp | Access control audit |
+
+## Storage Optimization
+
+### Design Choices
+- **Map-Based Storage** for Soroban compatibility
+- **Counter-Based IDs** for O(1) generation
+- **Read-Time Expiration** checking (no cleanup jobs)
+- **Separate Lists** for efficient queue processing
+
+### Cost Analysis
+Per User Lifecycle:
+- Submit: ~500 bytes
+- Approve: ~600 bytes
+- Total: ~1,650 bytes per user
+
+For 1000 Users:
+- Storage: ~1.6 MB
+- Monthly rent: ~0.001 XLM
