... They facilitate the creation of customized programming logic across the blockchain, enabling the development of programmable finance and a programmable society. Smart contracts find extensive applications including electronic payments, controlling assets, multi-signature deals, the Internet of Things, cloud computing, and the economy of collaboration (Tern, 2021). Smart contracts thus represent an essential part of Web3 Technologies, allowing for a new paradigm of automated, trustless, decentralized, and ubiquitous services and applications. ...
The evolution of blockchain technology, notably exemplified by Bitcoin, heralded a new era where smart contracts have taken center stage. Smart contracts are ingenious self-executing contracts that empower automatic enforcement of contractual terms, eliminating the need for intermediaries or trusted third parties. Consequently, smart contracts offer multifaceted benefits, including streamlined administrative procedures, cost savings, enhanced operational efficiency, and risk reduction. This chapter aims to provide the pivotal technical aspects of smart contracts and their significance within the blockchain technology landscape. The authors begin by elucidating fundamental concepts, structural intricacies, and the working principles of smart contracts. Subsequently, they delve into the technological platforms that support smart contracts. They then provide an overview of the application landscape, with a focus on Ethereum and hyperledger fabric platforms. Finally, they address the challenges associated with smart contract technology and offer insights into potential opportunities.
... Overall, smart contracts offer increased efficiency, transparency, security and cost savings compared to conventional contracts. Their automation capabilities and integration with blockchain technology have the potential to revolutionize contract management in various industries [108]. Table 5 shows the smart contracts in an agricultural product traceability scenario. ...
In recent years, with the frequent crises of trust in the food industry, food safety issues have become an issue of particular concern to consumers. The traditional agricultural food logistics and transportation model can no longer guarantee the traceability of food safety information, and it is particularly important to establish an effective traceability system. Therefore, a traceability system is applied as a tool to assist in the assurance of food safety and quality, as well as to achieve consumer confidence. Blockchain is a new decentralized infrastructure and distributed computing paradigm that has gradually emerged. Blockchain has the characteristics of decentralization, immutable information and trustworthiness. When blockchain is applied to the traceability system of agricultural products, the quality of agricultural products will be well guaranteed. This article aims to provide a comprehensive review of the recent research efforts on traceability in agricultural products based on blockchain technology. First, the method of content analysis used in this article to sort out the papers is introduced. Second, the background concepts of blockchain and the key technologies are presented. Thirdly, the traceability applications based on blockchain technology for agricultural products are described in detail. Finally, we expand on the current trends and provide new perspectives pertaining to this exciting application of this field.

The work presented in this article focuses on document forgery. Document fraud is a generic term used to designate a fraud, a falsification of a document. The said falsification can be observed in several sectors of everyday life. For a better illustration, let's consider a system for producing civil status forms. The birth certificate is generally the basis of any individual's life, and if this document is falsified, it can have repercussions at several levels, particularly in the academic field, where false diplomas, false national identity cards, false passports, false marriage certificates, etc. are obtained. It is therefore demonstrated that a secure production unit for civil status forms can be beneficial to both developed and developing countries. In addition, smart contract is proposed using a private Hyperledger fabric blockchain for validation of civil status documents, and a non-state public key management infrastructure is also proposed to authenticate the nodes that will validate the transactions. This improved blockchain solves the problem of falsification of civil status documents, as false nodes can contribute to the validation of a transaction. The contribution of such a hybrid system is of paramount importance for the identity of civil status documents on the one hand and for the identity of documents in general, and the blockchain to guarantee the distributed, un-forgeable, non-repudiation, transparency and disintermediation character.
... Smart contracts are event-driven, state-based code contracts and algorithm contracts that have received a lot of attention and study due to the rapid advancement of blockchain technology. To complete all steps of the smart contract procedure, the protocol and user interface are used [25].

Financial sharing is a phenomenon that people share unused resources in order to reduce financial burden. Financial sharing has been widely used by students, housewives, the elderly and others. Many researchers have investigated this human behavior, such as Yang (2012). Yang's research shows that there are three factors that affect the frequency of financial sharing: personal characteristics, social relations and economic conditions. In addition, Huang et al. (2018) provided a new perspective on financial sharing from the perspective of technological evolution and its impact on human life in the 5G era. And its peak theoretical transmission speed can reach tens of gigabits per second, providing full support for innovative applications of blockchain technology. Starting from the characteristics of blockchain technology in the 5G network background, this paper expounds the influence of blockchain technology on financial sharing in the 5G network background, and further analyzes the application in financial sharing in the 5G network background.
This paper mainly discusses the theory and related technology of trusted transactions in modern service industry. Three prohibition principles of trusted transactions in modern service industry are summarized by lucubrate. Through detailed research on the blockchain technology, especially the Consortium Blockchain, we find that its innovation and characteristics meet all the requirements of trusted transactions. After that, we discuss the cryptography and computer principles and technologies behind the three prohibition principles of blockchain supporting trusted transactions in details, implemented on which the smart contract technology is analyzed. On this basis, we put forward the overall framework of trusted transaction based on blockchain technology, and take the e-commerce platform as an example, and the basic design on multilink and microservice framework. Ultimately, we conduct study on big data credit investigation and credit evaluation for trusted transactions under the blockchain system, and make a preliminary discussion on the dynamic penetrating supervision model based on big data of blockchain transactions.KeywordsTrusted transactionsBlockchainThree prohibition principlesPenetrating supervisionSmart contract
