Abstract

This proposal introduces a “Continuous Verifiable Reality” (CVR) framework designed to solve the collateral opacity problem in Real-World Asset (RWA) lending. By integrating a decentralized oracle network with specific slashing conditions for physical state verification (IoT data), we propose a method to dynamically reduce risk-weighted assets (RWA) on-chain, aligning with Basel III capital optimization standards.

Below is the mathematical model for the oracle reputation system and the resulting capital efficiency calculations.

1. The Trust Anchor: Oracle Reputation & Slashing Mechanism

To ensure the integrity of physical asset data (e.g., temperature, location, pressure) entering the settlement layer, we utilize a reputation-weighted consensus model (R\_{i,t}) that prioritizes accuracy over stake size.

1.1 Reputation Formula

An oracle node’s reputation score at time t is calculated as:

$$R_{i,t} = \alpha \cdot \text{Accuracy}_{i,t} + \beta \cdot \text{Uptime}_{t} + \gamma \cdot \text{Stake}_{i,t} - \delta \cdot \text{Disputes}_{i,t}$$

Weighting Parameters:

  • \\alpha = 0.4 (Accuracy): Highest weight to ensure data integrity.

  • \\beta = 0.3 (Uptime): Incentivizes reliability for continuous data streams.

  • \\gamma = 0.2 (Stake): Modest weight to prevent pure plutocracy.

  • \\delta = 0.1 (Dispute Penalty): Immediate reduction for involvement in contested data rounds.

1.2 Incentive & Slashing Conditions

To maintain Byzantine fault tolerance regarding physical data states, specific slashing conditions are enforced:

  • Consensus Deviation: Reporting data that deviates >3\\sigma (standard deviations) from the median consensus triggers a 15% stake slash.

  • False Data Submission: Cryptographically proven malicious data injection results in a 20% stake slash.

  • Downtime: Availability <95\\% results in a 5% stake slash.

2. Economic Impact: Basel III Capital Optimization

The primary utility of this CVR layer is the reduction of counterparty credit risk for on-chain lending pools. By moving from static document-based verification to real-time state verification, we apply a “Verification Discount” to the Risk-Weighted Asset (RWA) calculation.

2.1 Risk Weight Formula

For institutional capital providers, the risk-weighted asset value is adjusted as follows:

$$RWA_{CVR} = \text{Exposure} \times \text{RiskWeight} \times (1 - \text{VerificationDiscount})$$

Projected Impact:

Based on continuous monitoring of commodity collateral (e.g., LNG, Coffee), the model estimates a Verification Discount (D\_{ver}) of 20–50%.

  • Standard Model: RWA = \\$10M \\times 100\\% = \\$10M

  • CVR Model: RWA = \\$10M \\times 100\\% \\times (1 - 0.40) = \\$6M

This results in a 40% reduction in capital requirements, significantly improving the Sharpe ratio of RWA-backed liquidity pools by reducing the denominator (volatility/risk) without altering the yield.

3. Ecosystem Synergy and Future Research

Our Continuous Verifiable Reality (CVR) framework is designed to function as a trust-minimized anchor layer, providing provably honest, high-frequency RWA data to the ecosystem. We see immediate synergy with several ongoing research efforts:

  1. L2 Confidentiality: For institutional adoption, data confidentiality is non-negotiable. Running the CVR Trust Anchor on L2 protocols, such as Obscuro, a new decentralised Layer 2 rollup protocol with data confidentiality, would allow institutional lenders to benefit from Basel III optimization without revealing proprietary commercial data or specific collateral metrics.

  2. Smart Contract Safety: The Transaction Carrying Theorem (TCT) Proposal: design-level safety for smart contract offers a mechanism to formally verify that smart contract logic adheres to safety properties at runtime. Integrating TCT with the CVR’s Integrated Risk Layer could provide design-level security guarantees for the on-chain risk models, proving the slashing and risk-weight calculations are safe from internal logic bugs.

  3. Economic Mechanism Design: The goal of adjusting incentives to mitigate systemic risk, as discussed in Reducing LST dominance risk by decoupling attestation weight from attestation rewards, is highly analogous to the economic security of our CVR framework. Our Oracle Reputation Model and slashing conditions similarly use economic incentives to enforce a non-technical property: Continuous Verifiability of physical state. We welcome collaboration on optimizing these shared incentive structures.

I welcome feedback on the weighting parameters (\alpha, \beta, \gamma) and the feasibility of applying this slashing mechanism to high-frequency IoT data feeds on L2 networks.
