“…(1) Condition (11) shows that each smart contract has its own dependent smart contracts and all its dependent smart contracts are within the smart contract set SC. This indicates that smart contracts in a topic form a completely dependent relationship, and they do not depend on the external smart contracts.…”

<div>Currently, the P2P method is that its software runs on a P2P hardware environment. However, the software is not a P2P one. It is difficult to match the scenarios in which the users' requirements change often. Meanwhile, if the software is out of service, all participants are affected. Thus, in this paper, we propose the fully decentralized application model, in which a P2P software runs in a P2P hardware environment. It is based on the blockchain, as a blockchain provides a secured P2P hardware environment. We focus on its P2P software (the P2P smart contract). A P2P smart contract is formed by smart contracts from its participants instead of a third party. It allows each participant to specify its requirement in a turning-complete way and the failure of one smart contract does not affect other smart contracts. We first describe the requirement of the P2P smart contract and the dependence among them. Then, we propose different ways to pair associated smart contracts. At last, we verify the proposed P2P smart contract model, and it shows more flexibility and robustness than the centralized software method.</div>

<div>Smart contract-based methods are used to implement the blockchain applications. While smart contracts have separate pre-deployed steps, which are suitable for applications that are deployed once and invoked many times. However, there are smart contracts that are used only one time (the disposable smart contract) or few times. Pre-deployment requires an additional step and additional transactions, which bring burdens (such as longer waiting time and more transaction fees) to users. In this paper, we propose a new Lifecycle model of smart contracts, which allows combining the pre-deployment with function invocations. This facilitates the usage of the disposable smart contract, as users are only required to send one transaction to perform both the pre-deployment and the function invocation. Together with the smart contract separation, it also allows participants to customize their special smart contracts at the request time. At last, we verify the proposed model and it shows the potential to save additional burden and to facilitate the usage of the smart contract.</div>

“…Indeed, contrary to design and implementation of traditional software applications, the development of smart contracts implies patterns and best practices that are in their early stage. For this reason we focus on the on-chain application of the proposed dApp, emphasizing all the best practices adopted (see works by Marchesi et al [40,42], Marchesi et al [43] for more details).…”

A Blockchain-Based Traceability System in Agri-Food SME: Case Study of a Traditional Bakery

In this paper we present a blockchain based system for the supply chain management of a typical Italian bread. Goal of the system is to guarantee a transparent and auditable traceability of the Carasau bread in such a way that each actor of the supply chain can verify the quality of the products and the conformity to the normative about the hygienic-sanitary conditions along the chain. To realize this system we relied on the Blockchain and the Internet of Thing technologies in order to provide a trustless environment, in which trust is placed in cryptography, in mathematical operations and on the network, and not in public or private companies. Thanks to the use of digital technologies the system aims to reduce the data entry errors and the risk of tampering. Our system is designed in such a way that, along the supply chain, the nodes equipped with several sensors directly communicate their data to Raspberry Pi units that elaborate and transmit them to Interplanetary File System and to the Ethereum Blockchain. Furthermore, we designed ad hoc Radio Frequency Identification and Near Field communication tags to shortly supply the proposed system with information about the products and batches. The system will easily allow end consumers to have a transparent view on the whole journey from raw material to purchased final product and a supervisory authority to perform online inspections on the products' quality and on the good working practices.
