Proveniq Ledger

The Source of Truth

Proveniq Ledger is the immutable record system that establishes and maintains the chain of custody for every asset in the ecosystem. It answers the fundamental question: "What is the verified history of this item?"

Why Provenance Matters

Architecture

Immutability Model

Ledger uses a hybrid approach combining:

1. Merkle Tree Structure — Cryptographic proof of data integrity
2. Distributed Storage — Redundant copies across multiple regions
3. Blockchain Anchoring — Periodic hash commits to public chains

Event Types

Chain of Custody

Building the Chain

Every asset accumulates a verifiable history:

1. Genesis — Item registered in Home app
2. Verification — Hardware confirmation via Locker
3. Monitoring — Continuous SmartTag telemetry
4. Transactions — Sales, loans, claims recorded
5. Audit — Third-party verification requests

Querying History

The Ledger API supports:

• Full Chain — Complete history from genesis to present
• Time Range — Events within specified dates
• Event Filter — Specific event types only
• Verification Proof — Cryptographic proof of specific entry

Integration with Ecosystem

Ledger → Applications

• ClaimsIQ — Pulls provenance for claim validation
• Bids — Displays verified history to buyers
• Capital — Confirms collateral authenticity

Compliance & Legal

Legal Standing

Ledger entries are designed to be:

• Admissible as business records
• Compliant with e-signature laws
• Suitable for regulatory audits

Data Retention

• Active Assets — Indefinite retention
• Transferred Assets — 7-year minimum
• Regulatory Holds — Extended as required
