“…In the field of model-driven methods, Udokwu and Norta [21] presented a goal-modeling method to systematically describe the requirements of inter-organizational collaboration systems based on blockchain technology. In a related paper, Udokwu et al [22] presented and evaluated the decentralized agent-oriented modeling (DAOM) framework for building dApps that support inter-organizational collaborations. The evaluation, made by 15 industry experts, showed the usefulness and applicability of DAOM for this type of dApps, and the effectiveness of the related tool support.…”

There is a growing demand for transparency along the agri-food chain, both from customers and governments. The adoption of blockchain technology to enable secure traceability for the management of the agri-food chain, provide information such as the provenance of a food product and prevent food fraud, is emerging rapidly, due to the inherent trust and inalterability provided by this technology. However, developing the right smart contracts for these use cases is even more of a challenge than it is for those used in other fields. Several management systems for the agri-food chain based on blockchain technology and smart contract have been proposed, all however ad-hoc for a specific product or production process and difficult to generalize. In this paper, we propose a new approach to easily customize and compose general Ethereum-based smart contracts designed for the agri-food industrial domain, to be able to reuse the code and modules and automate the process to shorten development times, while keeping it safe and reliable. Starting from the definition of the real production process, we aim to automatically generate both the smart contracts to manage the system and the user interfaces to interact with them, thus producing a system that works semiautomatically. Additionally, we describe a honey production case study to show how our approach works. Future work will first extend the scope of the approach to other supply chains, furthermore, while the current platform used is Ethereum, in the future our approach will be easily extended to other blockchain platforms.INDEX TERMS Agri-food product traceability, blockchain, smart contract, supply chain.

Smart contracts and Blockchain are necessary for transactions in supply chain management. A smart contract is an agreement in the form of a cryptographic code digitally signed by the actors. This technology holds the data transaction transparently and securely between the actors. The actors may benefit without intermediaries involved in the transaction. Supply chain management will be easily tracked by decentralized data sharing. Supply chain management involves transactions in agricultural sectors such as farmers, Village Cooperatives units, distributors, and consumers. The Cooperative is a party that buys goods from farmers and sells them to consumers. A smart contract is a digital signature that can access the system in transactions. The system records log activities that show the origin of transactions. All actors can see the transaction of agricultural products stored in the blockchain ledger in the Blockchain. This paper discusses blockchain-based smart contracts scenario for supply chain management that is simulated and implemented in the Serious Game. The Game is developed using Unity 3D Development Platform, programming language contract using Solidity, Moralis as Web3 Development Platform and dApp as backend blockchain, Network Environment Polygon Ethereum, and Database that is Redis Enterprise, MongoDB Compass, and Mumbai Testnet.

High-quality luxury products cater to a specific group of consumers due to their durability and the value attached to them. Counterfeiting luxury products has resulted in economic losses for both the producers and consumers. The market for counterfeit luxury products has continued to grow due to the difficulty in authenticating genuine luxury products. The traditional system of verification largely depends on the expert use of specialized equipment for visually inspecting physical luxury products and their associated certificates. This conventional process of authenticating luxury products is expensive, slow, and not easily accessible to consumers. Hence, there is a need for a digital verification approach for luxury products. Blockchain provides the potential for providing traceable and immutable information about a given luxury product. The focus of this paper is to develop a blockchain decentralized application (DApp) for authenticating luxury products in the class of luxury accessories such as jewelry across their respective lifecycles. To achieve this, qualitative analytics is applied to identify useful features for the digital authentication of luxury products. Blockchain requirement engineering modelling is then applied to explore the use of blockchain technologies to realize the features that guarantee transparency in the ownership and use of luxury products. Furthermore, this paper explores the existing blockchain technologies for realizing and implementing the developed requirements of the authentication DApp for luxury products. The selected blockchain technology stack is applied in prototyping authentication systems for luxury products. The implemented platform is simulated to demonstrate the operations carried out in authenticating luxury products.
