System Architecture
Overview
PRVNZ implements a hybrid architecture combining distributed multi-party computation (MPC), trusted execution environments (TEEs), and a Bitcoin-backed treasury blockchain to create a secure, scalable digital rights management protocol.
Design Goals
- Security First: Hardware-rooted trust with distributed cryptographic operations
- High-Performance Primary Settlement: PRVNZ blockchain with 270,000+ TPS capacity
- Bitcoin-Backed Reserves: 100% BTC backing with verifiable proof-of-reserves
- Privacy by Design: Configurable privacy with selective disclosure
- Optional Multi-Network Support: Canton Network and other institutional platforms as secondary options
- Developer Friendly: Invisible blockchain complexity for end users
- Treasury Transparency: Real-time proof-of-reserves verification
System Components
Application Layer
Purpose: User-facing interfaces and integrations
Components:
- SDK libraries (C++, Rust, JavaScript, Python)
- VST/AU plugin integrations
- Web applications
- Mobile applications
- API endpoints
Responsibilities:
- User authentication
- License management
- Asset upload/download
- Transaction initiation
- Wallet abstraction
Digital Vault Layer
Purpose: Secure asset storage and licensing logic
Components:
- Vault Container (TEE-backed)
- License Engine (programmable rules)
- Asset Storage (hash-verified)
- Key Management (MPC-based)
- Enclave Orchestration
Responsibilities:
- Asset encryption/decryption
- License verification
- Fractional ownership tracking
- Access control enforcement
- Nested enclave execution
Privacy Layer
Purpose: Configurable confidentiality and selective disclosure
Components:
- Privacy Engine
- Hash Change Tracking
- Encrypted State Channels
- Zero-Knowledge Proofs (planned)
- DAML Privacy Contracts
Consensus Layer
Purpose: Transaction ordering and validation
Components:
- PoA Validator Nodes (TEE-verified)
- Sequencing Service
- State Synchronization
- Attestation Service
- Network Monitoring
Primary Settlement Layer
Purpose: Economic foundation and reserve backing
Components:
- PRVNZ Blockchain (Native settlement)
- BTC Treasury (1:1 backing)
- Multisig Custody System
- Proof-of-Reserves Service
- Token Minting/Burning
- Fee Collection
Responsibilities:
- Maintain 100% BTC reserves
- Process all primary transactions
- Verify reserve ratios continuously
- Manage Bitcoin custody
- Provide transparent verification
- Handle redemptions
Secondary Settlement Layer
Purpose: Optional institutional settlement and cross-network composability
Primary Option - Canton Integration:
- Participant Node (optional)
- DAML Runtime
- Synchronization Domain
- Canton Coin Integration
- Cross-App Composability
Key Point: Canton and other networks are optional secondary settlement layers. The PRVNZ blockchain is the primary settlement layer for all transactions. Users can optionally settle certain transactions through Canton Network for additional privacy features or institutional compliance requirements.

Multi-Layer Defense
- Bitcoin Network: Proof of Work consensus, global decentralization
- Multisig Treasury: Threshold signatures, no single point of control
- TEE Hardware: Hardware-backed key isolation, remote attestation
- PoA Validators: Known entities with legal accountability
- MPC Key Splitting: Distributed key shares (3-of-5 threshold)
- Continuous Monitoring: Real-time verification, automated alerts
Cryptographic Primitives
Hash Functions:
- SHA-256 for content addressing
- Blake3 for fast hashing
- SHA3-256 for state commitments
Signatures:
- ECDSA (secp256k1) for Bitcoin compatibility
- Ed25519 for high-performance signing
- BLS signatures for aggregation
Encryption:
- AES-256-GCM for symmetric encryption
- X25519 for key exchange
- RSA-2048 for legacy compatibility
Threshold Cryptography:
- Threshold ECDSA
- Shamir Secret Sharing for key distribution
- Verifiable Secret Sharing (VSS)
- Distributed Key Generation (DKG)
Scalability Architecture
Current Design Targets
- Throughput: 270,000+ TPS (achieved in internal testing)
- Latency: <2s transaction finality
- Storage: Off-chain with hash verification
- Validator Set: 10-100 nodes (elastic)
