Security & Privacy

W3A employs multi-layered security protection to ensure user data and asset safety. **Network Security**: - 24/7 Security Operations Center - DDoS Protection (>1Tbps capacity) - Web Application Firewall (WAF) - Intrusion Detection System (IDS) - Real-time anomaly monitoring **Smart Contract Security**: - Multiple top-tier audits (3+) - Formal verification - Bug bounty program (up to $100K) - Progressive upgrade mechanism - Emergency pause functionality **Data Security**: - End-to-end encryption (AES-256) - Fine-grained access control - Data classification management - Complete audit logs - Regular security assessments

**Zero-Knowledge Proofs (ZKP)**: ZKP allows one party to prove a statement is true without revealing any additional information. Applications: - Computation verification: Prove AI results are correct without exposing raw data - Identity verification: Prove user identity without revealing personal info - Transaction privacy: Verify transaction validity while protecting details **Federated Learning**: A distributed ML approach where data stays on local devices, only sharing model updates. Benefits: - Data stays local: Raw data never leaves user devices - Privacy preserved: Only encrypted model parameters transmitted - Collaborative training: Multiple parties train models without sharing data **Homomorphic Encryption**: Allows computation on encrypted data, with results matching plaintext computation. Applications: - AI inference on encrypted data - Protecting model weight privacy - Secure multi-party computation

**What is RWA Certification?** RWA (Real World Assets) certification maps real-world assets to blockchain as verifiable, traceable, tradeable on-chain assets. **Three RWA Types**: **1. Compute RWA** - Asset: GPU and compute devices - Certificate: Compute NFT - Value: Continuous earnings from compute contribution - Process: Device registration → Performance verification → NFT minting → Earnings binding **2. Model RWA** - Asset: AI models - Certificate: Model Revenue Certificate - Value: Revenue share from model usage - Process: Model registration → Quality assessment → Certificate generation → Usage tracking **3. Data RWA** - Asset: Training data, creative content - Certificate: Data Asset Certificate - Value: Data usage revenue - Process: Data labeling → Privacy processing → Certificate generation → Authorization management

**Node Authentication**: - Wallet signature verification - Device fingerprinting - Multi-factor authentication (optional) **Communication Security**: - TLS 1.3 encrypted transmission - Certificate pinning - Secure key exchange **Task Security**: - Encrypted task data transmission - Sandboxed execution - Result verification mechanism - Anomaly behavior detection **Asset Security**: - Multi-signature wallets - Hot/cold wallet separation - Withdrawal delay protection - Large transaction review **Best Practices**: 1. Use strong passwords and hardware wallets 2. Regularly update node software 3. Enable all security features 4. Monitor for anomalies 5. Backup important data

**Global Compliance Framework**: - GDPR (EU General Data Protection Regulation) - CCPA (California Consumer Privacy Act) - Other regional data protection laws - KYC/AML compliance **User Rights**: - Right to access: View all your data - Right to deletion: Request personal data deletion - Right to portability: Export your data - Right to withdraw consent: Revoke data usage authorization **DAO Governance**: - Security policies decided by community vote - Transparent disclosure of major security events - Security budget managed by DAO - Continuous bug bounty program **Incident Response**: - 24-hour security response team - Tiered incident handling process - Timely user notification mechanism - Post-incident analysis and improvement If you discover security issues, please contact our security team immediately.
