Philosophy
Privacy-First Commerce
TariMarket L2 is built on the principle that financial privacy is a fundamental human right. By leveraging the Tari blockchain's privacy features and extending them to Layer 2, we enable merchants and buyers to transact without sacrificing their financial privacy.
Scaling Without Compromise
The blockchain trilemma suggests we must choose between security, decentralization, and scalability. We reject this false choice. By implementing state channels as a Layer 2 solution, TariMarket L2 achieves:
- Security: All transactions are cryptographically signed and can be settled on Layer 1
- Decentralization: No central authority controls the network or state channels
- Scalability: Instant, low-cost transactions through off-chain state updates
Core Principle: The security of Layer 1 combined with the performance of off-chain computation. TariMarket L2 brings the best of both worlds to privacy-focused commerce.
Decentralized Infrastructure
We believe in true decentralization. TariMarket L2 is designed so that:
- Anyone can run a node
- No permission is required to participate
- No single entity controls the network
- All code is open source and auditable
- State channels are peer-to-peer with no intermediaries
Practical Privacy
Privacy should not come at the cost of usability. TariMarket L2 aims to make private, secure commerce as easy as traditional e-commerce, with instant confirmations and minimal fees while maintaining strong privacy guarantees.
Architecture
Two-Layer Design
TariMarket L2 operates as a hybrid system combining the security of Layer 1 with the performance of Layer 2:
Layer 1 (Tari Blockchain): Handles collateral deposits, dispute resolution, and final settlement. Provides the security foundation for all Layer 2 operations.
Layer 2 (State Channels): Handles instant marketplace transactions between channel participants. Updates happen off-chain with minimal latency and cost.
State Channel Protocol
State channels enable participants to transact off-chain while maintaining the ability to settle on-chain at any time:
- Participants lock collateral on Layer 1 to open a channel
- All subsequent transactions occur off-chain with cryptographic signatures
- Channel state can be cooperatively closed or enforced via dispute resolution
- Nonce-based replay protection ensures transaction ordering
Marketplace Operations
The marketplace layer manages:
- Product listings with metadata and pricing
- Order placement and status tracking
- Balance management across channel participants
- State synchronization between peers
Security Model
Multi-layered security approach:
- Ed25519 digital signatures for all state transitions
- Multi-party signature requirements for channel updates
- BLAKE3 cryptographic hashing for state commitments
- Challenge periods for dispute resolution
- Fraud proofs to prevent malicious behavior
