This research investigates the role of blockchain technology in revolutionizing agricultural supply chains by ensuring transparency, security, and traceability. Conventional blockchain systems face significant hurdles, such as scalability constraints, energy inefficiency, and inadequate identity management, as detailed in Sect. 3. To address these, we propose an innovative four-layer framework (Users, Regional Office, Canister Smart Contract, Database) leveraging the Internet Computer Protocol (ICP). This system integrates Verifiable Credentials (VC), Self-Sovereign Identity (SSI), and a Decentralized Key Management System (DKMS) to provide secure, user-controlled identity verification, thereby mitigating the risks of unauthorized access and data breaches. By combining ICP energy-efficient canisters, upgradeable smart contracts, and hybrid storage with IPFS and databases, the framework enhances scalability and cost-effectiveness. The incorporation of a database to store major product data (public data) and shifting the major computational load to the database gives this system model a new edge. Therefore, exploring these technologies and acknowledging their benefits. This study advocates for decentralized, identity-focused solutions to transform agricultural supply chains, promoting trust, efficiency, and sustainability across global markets.

摘要

This research investigates the role of blockchain technology in revolutionizing agricultural supply chains by ensuring transparency, security, and traceability. Conventional blockchain systems face significant hurdles, such as scalability constraints, energy inefficiency, and inadequate identity management, as detailed in Sect. 3. To address these, we propose an innovative four-layer framework (Users, Regional Office, Canister Smart Contract, Database) leveraging the Internet Computer Protocol (ICP). This system integrates Verifiable Credentials (VC), Self-Sovereign Identity (SSI), and a Decentralized Key Management System (DKMS) to provide secure, user-controlled identity verification, thereby mitigating the risks of unauthorized access and data breaches. By combining ICP energy-efficient canisters, upgradeable smart contracts, and hybrid storage with IPFS and databases, the framework enhances scalability and cost-effectiveness. The incorporation of a database to store major product data (public data) and shifting the major computational load to the database gives this system model a new edge. Therefore, exploring these technologies and acknowledging their benefits. This study advocates for decentralized, identity-focused solutions to transform agricultural supply chains, promoting trust, efficiency, and sustainability across global markets.
