“…Consequently, all transactions remain visible. Finally, this process is made even faster by smart contracts, the main purpose of which is to accelerate transactions thanks to a set of rules that are stored on the blockchain and executed automatically [10]. An example that highlights the significance of these smart contracts is the vending machine.…”

Food product safety and quality are considered to be of the utmost significance on a global scale. Highly publicized food safety incidents have significantly increased public interest in food traceability, defined as “the ability to track any food, feed, food-producing animal or substance that will be used for consumption, through all stages of production, processing, and distribution” (European Union). The World Health Organization (WHO) suggests that governments, producers, and consumers work together to ensure food safety, which calls for the dissemination of pertinent information throughout complex food value networks. Therefore, it is in the best interest of profit-driven businesses to implement information systems for tracking food goods, a significant byproduct of which is the likelihood of increased profitability. This paper aims to explore the ample possibilities for such implementations that are now available thanks to blockchain technology. In particular, the goal is to explore the dynamics of this technology and identify how it helps to create good customer relationships. For this purpose, the case of Lavazza, an important Italian roasted coffee company that has recently introduced a blockchain-tracked product to the market, is analyzed in detail, including all the steps that made the application of the technology possible and how it was finally communicated to the consumer. The case study offers a concrete example that resulted from both stakeholders’ internal need for greater traceability and consumers’ external need for greater transparency regarding the company’s sourcing processes. In this pilot project, collaboration among all the entities that are part of the chain was essential to delivering a formative, customized, and ultimately, easy-to-understand experience to the end consumer. Finally, Lavazza is an example of a company that decided to challenge itself by following a trend that will be increasingly present in future socioeconomic scenarios.

“…Blockchain technology offers a novel approach to addressing the issues of fragmented data, data leakage, and privacy security preservation. Blockchain has been adopted extensively in the supply chain, healthcare, IoT, and other security/privacy critical fields 9‐11 and has exhibited significant potential to tackle the aforementioned issues in healthcare 12 . Substantial work has been conducted on applying blockchain techniques to IoT data sharing 13 .…”

Health Internet of Things (Health IoT) has been limited by isolated information and a lack of security. As the combination of blockchain and Health IoT could potentially address these two limitations, it has attracted significant interest. However, blockchain‐based systems often fail to balance data sharing and privacy protection. Therefore, we proposed a Health IoT‐based privacy‐preserving data sharing blockchain system. We designed a privacy‐preserving method based on the content extraction signature scheme to enable patients to establish fine‐grained privacy protection. We designed a Byzantine fault‐tolerant leader election mechanism that enhances the security of the Raft algorithm while providing efficiency in the data sharing. Furthermore, we designed a summary contract to ensure efficient data retrieval. The proposed mechanism was evaluated in terms of the efficiency and security. The simulation and analysis results demonstrate that our scheme offers a secure and effective technique for achieving privacy‐preserving and efficient sharing of IoT medical data.
