Abstract
The traceability of agricultural products has always been one of the most important things that customers care about. For the past decades, the trend of applying Internet of Things (IoT) technology to agriculture has been on an exponential rise and has also shown great success in different aspects. Not only crops can be irrigated and taken care of more precisely, but more reliable production history can be created based on the environmental data collected by IoT sensors. To achieve a trustable traceability for agricultural production process, data security becomes a major factor after the collection of massive data via IoT. By using blockchain technology for data storing, integrity and reliability can be ensured due to its immutability. Furthermore, when dealing with several components (producer, processor, distributor…etc.) on a food production chain, blockchain also has the ability to connect untrusted nodes and restrict them in following certain protocols. This study designs and implements an agriculture blockchain service platform for farm-to-fork traceability with IoT sensors. The Ethereum blockchain technology is employed and smart contracts are also designed to support tampering-proof data storing and provide reliable financial transactions which may happen throughout the entire food production chain.
