4.3 Coordination Mechanism Between On-chain and Off-chain Assets
RAC maintains a dual-track strategy of “on-chain verifiable ownership” and “off-chain real-time synchronization” to ensure consistent asset data and trustworthy transaction environments. A standardized mapping protocol and off-chain data pipeline power this tightly integrated system.
On-Chain Asset Mapping: RAC tokenizes assets using ERC-20/721/1155 standards, providing each asset with a unique ID and traceable ownership. Tokens are linked via smart contracts to off-chain data such as legal title, valuation documents, and custody proofs. Hashes of these documents are recorded on-chain to create immutable digital records.
Off-Chain Data Integration and Updates: RAC connects with third-party providers (e.g., asset managers, appraisal firms, custodians, insurers) via APIs to pull updates on rent payments, repayments, price adjustments, and compliance reviews. These are processed through a data relay engine, then encrypted, structured, and submitted to on-chain contracts for synchronization.
Cross-Verification and Audit Mechanism: RAC’s State Validation Contracts validate the consistency of on-chain/off-chain data. The system also integrates decentralized oracles (e.g., Chainlink) for multi-source verification. Periodic snapshot reconciliations allow auditors and regulators to verify platform integrity.
Asset State Tracking: All lifecycle events (e.g., revaluation, staking, default, liquidation) generate on-chain hashed events monitored by platform listeners. Users can track full asset histories via RAC’s dashboard, strengthening transparency and investor trust.
Asset Unbinding and Token Destruction: When assets are terminated, exited, or defaulted off-chain, RAC uses permissioned smart contracts to freeze, reclaim, or burn associated tokens—ensuring alignment between token supply and real asset status.
This tightly integrated synchronization framework ensures real-time consistency and verifiability between physical and digital assets, enabling RAC to offer a secure, auditable, and trusted platform for RWA management. Looking forward, RAC will also explore ZKP-based anonymous validation and distributed audit protocols to further enhance data transparency and security.
