Freeze Mechanism
Technical Documentation for Freeze Mechanism in Asset Tokenization
The freeze mechanism within the asset tokenization platform is a critical feature for maintaining the integrity and security of the system. It serves as a safeguard against fraudulent activities and ensures compliance with stakeholder decisions. The mechanism is triggered either by fraud detection algorithms or by a majority vote (>2/3rd) from stakeholders. This document outlines the technical aspects of the freeze and unfreeze processes.
Freeze Mechanism Overview
Trigger Conditions for Freeze:
Fraud Detection Signal: When the integrated fraud detection algorithms identify a potential threat or irregular activity.
Stakeholder Vote: If more than two-thirds of the stakeholders vote for a freeze due to suspicious activities or compliance issues.
Predefined Conditions: Specific scenarios like suspected money laundering where external verification or documentation is required.
Asset Status Update:
Upon triggering a freeze, the asset's status in the smart contract is updated to "Frozen".
This status change restricts all transactions related to the asset, including transfers, staking, and usage as loan collateral.
Freeze Duration and Conditions:
Biometric Key Submission: Asset can be unfrozen when the user provides a biometric private key for verification.
Time-Based Unfreeze: The asset remains frozen for a predetermined duration set at the time of freezing.
Stakeholder Intervention: Asset can be unfrozen if a majority of stakeholders vote to reverse the freeze.
Conditional Unfreeze: Requires specific conditions to be met, such as submission and verification of compliance documents by oracles.
Unfreeze Mechanism
Smart Contract-Controlled Unfreeze:
The unfreeze process is governed by the smart contract, acting as a digital lock.
The contract evaluates the fulfillment of predefined conditions or inputs (e.g., biometric key verification, stakeholder vote, time lapse, or compliance document approval).
Oracle Integration:
For scenarios requiring external verification (e.g., document validation), oracles are used to provide the necessary confirmation to the smart contract.
The contract processes the oracle input to determine if the unfreeze conditions are met.
Security and Authentication:
The unfreeze process incorporates robust security measures to authenticate inputs, especially for biometric verifications.
Ensures that the unfreeze action is only executed when all specified conditions are accurately fulfilled.
Implementation Considerations
Smart Contract Design: The asset management contract should include functions to handle the freezing and unfreezing mechanisms efficiently and securely.
Integration with Fraud Detection: We need to ensure seamless communication between the fraud detection system and the freeze mechanism within the contract.
Stakeholder Voting Mechanism: We should implement a transparent and tamper-proof voting system within the DAO for stakeholders to initiate or revoke a freeze.
Compliance and Legal Adherence: The freeze mechanism must comply with legal standards, particularly in scenarios involving compliance documents and external verification.
User Notification and Transparency: Users should be promptly notified of the freeze status and the conditions for unfreezing, maintaining transparency in the process.
Conclusion
The freeze mechanism is an essential feature for the security and regulatory compliance of the asset tokenization platform. It acts as a protective measure against fraud and unauthorized activities, empowering stakeholders to safeguard their interests. The mechanism's effectiveness relies on its seamless integration with the platform's broader security and governance frameworks, ensuring that assets are managed responsibly and securely.
