Blockchain-Enabled Internet-of-Things Platform for End-to-End Industrial Hemp Supply Chain
This addresses data integrity and regulatory compliance issues for stakeholders in the industrial hemp industry, but it is incremental as it applies existing blockchain and IoT technologies to a new domain.
The paper tackles challenges in the Industrial Hemp Supply Chain, such as data tampering and lack of tracking, by developing a blockchain-IoT platform that improves quality control verification efficiency and ensures safety.
After being legalized as an agricultural commodity by the 2018 U.S. Farm Bill, the Industrial Hemp production is moved from limited pilot programs to a regulated agriculture production system, and the market keeps increasing since then. However, Industrial Hemp Supply Chain (IHSC) faces several critical challenges, including high complexity and variability, data tampering, and lack of immutable information tracking system. In this paper, we develop a blockchain enabled internet-of-things (IoT) platform for IHSC to support process tracking, scalability, interoperability, and risk management. Basically, we create a two-layer blockchain with proof-of-authority based smart contract, which can leverage local authorities with state/federal regulators to ensure and accelerate quality control verification and regulatory compliance. Then, we develop a user-friendly mobile app so that each participant can use smart phone to real-time collect and upload their data to the cloud, and further share the process verification and tracking information through the blockchain network. Our study indicates the proposed platform can support interoperability, improve the efficiency of quality control verification, and ensure the safety of regulated IHSC.
