Blockchain is an emerging technology that is based on the concept of distributed ledgers. It allows for pervasive transactions among different parties and eliminates the need for third-party intermediaries. Several of blockchain's characteristics make it suitable for use in the agriculture sector. Some of the potential applications of blockchain include efficient management of the food supply chain and value-based payment mechanisms. The products of agriculture are usually the inputs for a multi-actor distributed supply chain, in which case the consumer is usually the final client. The food chain involves several actors including farmers, shipping companies, distributors, and groceries. This makes the entire system to be distributed with multiple actors playing different roles throughout the chain. This currently used system is inefficient and unreliable in various aspects. This project aims to leverage blockchain technology to solve and address discrepancies involved in food supply chains.

Literature Review

The purpose of this survey is to place each work in the context of its contribution to understanding the research problem being studied. It defines data sources that other researchers have used. Literature review helps in viewing what came before, what did and did not work for other researchers. It also provides evidence to support our findings.

Features of Blockchain

In 2016, Yuan, Y. Wang conducted a preliminary study of the Blockchain-based Intelligent Transportation System. The study outlines an Intelligent Transportation System oriented, a seven-layer conceptual model for blockchain and presents a case study for blockchain-based real-time ride-sharing services. The study talks in brief about the pros and cons of blockchain technology. Once a new block is validated and added into the chain, this addition is permanent and can’t be tampered or removed and this feature of blockchain is known as immutable. This feature of blockchain leads to increased security in the network and is the easiest accountability of the network. In 2017, Zibin Zheng et al. presented a comprehensive overview on blockchain technology and blockchain architecture comparing some typical consensus algorithms used in different blockchains and also analysing the technical challenges of blockchain and recent advances.

Blockchain is described as “a revolutionary picture which has generated thousands of clones across computer networks” (Zibin Zheng et al., 2017). Bitcoin, Ethereum blockchains and smart contract implementations form the core of the development of cryptocurrencies. Dr.Gavin Wood (2014) discussed various features of the Ethereum blockchain by outlining how blockchain technology is implemented in a generalized manner in this framework and provided deep explanations about the design, implementation, issues encountered during implementation of blockchain, the various opportunities it provides and the future hurdles in the framework. In 2018, Dejan Vujičić et al. focused on providing a brief introduction into several aspects and evolutions in the field of Blockchain, also elaborating outlines about Bitcoin, Ethereum blockchains and smart contract implementations.
