Stránka 7: Security & Compliance

🔐 Cryptographic Foundations

  • Ed25519 signatures, Keccak/Blake2 hashing, AES-256 encryption
  • CryptoNote privacy: Ring Signatures, Stealth Addresses, RingCT
  • Configurable ring size (default 11; paranoid modes up to 101)
Transaction Privacy
────────────────────────────────
• Inputs anonymized via ring signatures
• Outputs hidden via stealth addresses
• Amounts hidden via RingCT commitments

🧱 Binary-Only Distribution & Integrity

  • Production builds ship as signed binaries only (no py sources)
  • Release artifacts include SHA256 checksums and signature files
  • Docker images: Ubuntu 24.04 minimal, non-root runtime, pinned deps
# Verify release
sha256sum -c checksums.txt  # All files: OK
gpg --verify zion-2.8.5.tar.gz.asc zion-2.8.5.tar.gz

Supply chain controls:

  • Pinned version locks, reproducible builds (WIP)
  • Multi-stage Docker to minimize attack surface
  • SBOM generation and image scanning in CI

🛡️ Node & Network Hardening

  • DoS/Spam: mempool limits, fee-per-byte policy, peer score bans
  • P2P: limited inbound peers, geo diversity, checkpointed headers
  • API: rate limiting, auth on admin endpoints, CORS rules
  • Keys: hardware-backed signing preferred, key rotation procedures
Mempool Limits:
  max_size_mb: 100
  max_tx_kb: 100
  fee_per_byte_min: 10  # atomic units
Peers:
  inbound_max: 64
  ban_score: 100
  ban_time: 24h

🔍 Audits, Testing, Monitoring

  • Third‑party security audit: planned Q2 2026 (code + infra + bridge)
  • Penetration testing before MainNet (Q3 2026)
  • Continuous fuzzing for tx parsing and P2P protocol
  • Monitoring: Prometheus/Grafana dashboards, alerting on anomalies
Audit Scope
• Consensus & Difficulty Adjustment
• Wallet cryptography (key images, RingCT)
• RPC shim & Stratum pool integration
• Bridge validators and multisig rules
• Docker & CI supply chain

👛 Wallet Security

  • Recommended: hardware-backed secrets (TPM/YubiKey)
  • Encrypted keystores with strong passphrases
  • View-only wallets for audit/reporting contexts
  • Recovery with seed phrases; offline backups strategy

⚖️ Compliance Position

  • Privacy by default; user sovereignty first
  • No KYC in protocol; optional integrations for partners off-chain
  • Humanitarian tithe accounted transparently (quarterly reports)
  • Jurisdiction-aware: binary distribution and documentation only

📜 Incident Response & Emergency Procedures

  • 72h emergency veto window (Core stewards) for critical exploits
  • Public disclosure policy with staged details and hotfix timelines
  • Postmortems required; follow-up ZIPs for protocol changes
