|
| ## Release Summary |
|
|
| ProofBridge Liner Safety Kernel v1.0 is now publicly released under Class A classification. This research-grade system release establishes a canonical circuit-breaker pattern for tokenized real-world assets, frozen at the safety-critical layer with complete documentation for independent evaluation. |
|
|
| ## What Is Included |
|
|
| ### Core System (Safety Kernel v1.0) |
| - **CircuitBreaker.sol**: 109-line smart contract with full test coverage (14/14 passing) |
| - **Prover Pipeline**: IPFS-based document verification system |
| - **Operations Dashboard**: Real-time monitoring interface |
| - **Deployment Infrastructure**: Foundry scripts for Polygon Amoy |
|
|
| ### Documentation Suite |
| - **Class A Release Specification**: Formal system definition and scope |
| - **Regulatory Reading Guide**: Compliance and supervisory orientation |
| - **Regulator Q&A Anticipation Sheet**: Prepared responses for regulatory dialogue |
| - **Integration Guide**: Technical implementation for developers |
| - **Economic Models**: 3-year cost projections and equity analysis |
| - **Risk Event Memo**: Hypothetical scenario documentation |
|
|
| ### Business Artifacts |
| - **Issuer Term Sheet**: Commercial integration terms |
| - **Strategic Positioning**: Competitive analysis vs. Chainlink |
| - **Task Report**: Complete project execution summary |
|
|
| ## Problem Solved |
|
|
| Tokenized real-world assets create "ghost-risk": the risk that on-chain tokens continue trading after their legal backing has silently changed off-chain. ProofBridge Liner prevents this by halting transfers when legal uncertainty is detected. |
|
|
| ## Key Characteristics |
|
|
| ### Safety Kernel Invariants (Frozen) |
| - Transfers must halt when legal truth is uncertain |
| - Reset authority exclusive to issuer (human oversight preserved) |
| - Oracle cannot transfer, mint, burn, or seize assets |
| - Enforcement gas-bounded and deterministic |
|
|
| ### Trust Model |
| - Single oracle MVP (upgradeable to threshold consensus) |
| - Explicit access controls and event logging |
| - Fail-closed enforcement philosophy |
| - No automatic circuit resets (issuer discretion required) |
|
|
| ### Economic Model |
| - Zero-fee integration at adoption |
| - Marginal operational cost <$0.05 per asset per month |
| - Equity-carry alignment (1% of protected assets) |
| - No token issuance or subscription fees |
|
|
| ## Verification & Reproducibility |
|
|
| All claims are supported by executable artifacts: |
|
|
| ```bash |
| git clone https://github.com/divhanimajokweni-ctrl/proofbridge-liner.git |
| cd proofbridge-liner |
| ``` |
|
|
| ## Intended Audience |
|
|
| - **Tokenized Asset Issuers**: Evaluate integration feasibility |
| - **Smart Contract Engineers**: Review implementation patterns |
| - **Risk & Compliance Teams**: Assess regulatory implications |
| - **Protocol Researchers**: Study ghost-risk mitigation approaches |
| - **Infrastructure Partners**: Explore integration opportunities |
| - **Regulators & Auditors**: Conduct technical review |
|
|
| ## Forward Compatibility |
|
|
| Future releases may introduce: |
| - Multi-oracle threshold consensus |
| - Hardware-backed key custody |
| - Registry integrations |
| - Multi-jurisdiction legal adapters |
|
|
| All future work will be versioned separately and will not alter v1.0 behavior. |
|
|
| ## Canonical Statement |
|
|
| > **ProofBridge Liner does not attempt to prove legal truth on-chain. It prevents the market from trading when legal truth is uncertain.** |
|
|
| ## Release Declaration |
|
|
| By publishing this release, the authors declare that: |
|
|
| - The Safety Kernel v1.0 is frozen and will not be modified |
| - All included artifacts are complete and independently verifiable |
| - No hidden dependencies or undisclosed trust assumptions exist |
| - The release is complete within its declared scope |
| - Future development will occur under new version numbers |
|
|
| ## Next Steps |
|
|
| ### For Evaluation |
| - Review the [Class A Release Specification](class-a-release-spec.md) |
| - Examine the [CircuitBreaker.sol](contracts/CircuitBreaker.sol) implementation |
| - Run the test suite and deployment scripts |
|
|
| ### For Integration |
| - Consult the [Integration Guide](integration-guide.md) |
