The Ancestral Archive is a decentralized system designed to record, manage, and track the provenance of agricultural assets using blockchain technology. This solution enables asset custodians to register, modify, and access records in a transparent, secure, and immutable environment. The system supports full lifecycle management, including the validation of document authenticity, reassigning custodianship, and access authorization for multiple participants.
- Register Agricultural Assets: Register new agricultural asset entries with detailed metadata, including volume, summary, and categories.
- Access Control: Manage access permissions for other participants, allowing for controlled visibility of asset records.
- Certification & Authentication: Allow certified evaluators to validate the authenticity of asset records.
- Custodianship Management: Facilitate the reassignment of custodianship and modification of asset details as necessary.
- Error Handling & Validation: Integrated checks to ensure data consistency, entry validation, and error handling for all operations.
The system is built on a smart contract architecture, where the following key elements are defined:
- Agricultural Asset Records: Stores detailed asset metadata, including the name, volume, custodian, categories, and timestamp.
- Access Authorizations: Manages the permissioning system, ensuring that only authorized participants can view or interact with the records.
- Authenticity Certifications: Records the certification status of each asset, ensuring that only approved evaluators can mark the asset as authenticated.
- Certified Evaluators: Maintains a list of authorized evaluators who are qualified to certify the authenticity of the assets.
- Register New Entry: Allows system administrators or asset custodians to register a new agricultural asset with relevant metadata.
- Purge Entry: Enables the permanent removal of an asset from the blockchain registry.
- Revoke Access: Permits custodians to revoke access for other participants, ensuring secure asset management.
- Inspect Entry: Lets authorized users inspect asset details if permitted.
- Certify Authenticity: Allows authorized evaluators to validate the authenticity of asset records.
- Modify Entry: Provides functionality to modify the details of a registered asset, including its name, volume, summary, and categories.
