This paper deals with the analysis of the technological implementation of blockchain in the field of food supply chain.
Blockchain has long been more than just the technology behind the cryptocurrency Bitcoin. Rather, the technology is now considered the real innovation, which experts believe has the potential to change business models, governments, and even societies. Above all, it is increasingly coming to the public's attention because of its many possible applications. Basically, the blockchain is a public register that enables users to collaborate in a trustworthy and transparent manner. The blockchain system connects all participants in a peer-to-peer network, so no intermediaries are required. In addition to the financial sector, supply chain management is also mentioned in various publications as an important application area for the technology. The food supply chain in particular is increasingly coming into focus due to the increasing complexity and internationalisation of supply chains, as well as the demand for transparency on the part of customers against the backdrop of sustainability. The goals of blockchain technology in the food supply chain include optimising the international exchange of goods and its documentation, minimising the need for middlemen, traceability, and real-time localisation of products. Retail giants, such as Walmart and Carrefour, recognised the potential of the technology early on and rely on IBM Food Trust to map their own product portfolio as transparently as possible.

Excerpt from the Book
3.2.1 Optimisation of the international Exchange of Goods and its Documentation
Complete documentation ensures the integrity of the data, which is desirable for many companies but essential for some industries (Tapscott & Tapscott, 2018). In the food industry, for example, production processes or transport conditions such as the cold chain must be verifiable (Korpela, Hallikas, & Dahlberg, 2017). Furthermore, digitalisation replaces previously paper-based processes and makes them more efficient and cost-effective (Leong, Viskin, & Steward, 2018). For companies, coordination becomes easier, so fewer mistakes happen. Data in the supply chain can be recorded incorrectly, twice or incompletely, not only through human error but also through active attempts at manipulation (Adelphi). With the help of blockchain technology, data can be stored in a tamper-proof way, which creates additional security for the end consumer (Schlatt et al., 2016). Smart contracts based on blockchain technology can simplify transactions and their documentation by implementing contract terms fully automatically after the parties involved have formulated them (Olnes et al., 2017).
