The Third Party

Cloud computing uses virtualization technology to provide users with different types of resources in the form of services. The third party plays a crucial role in coordinating cloud market between cloud providers and users. As for providing services or trading, the extra broker fees are required for the middleman because the third party facilitates transactions. Moreover, there is no guarantee that the third party is trusted, which can lead to information leakage, data tampering, and unfair trading. Blockchain technology is an emerging technology that can store and communicate data between entities that unnecessarily trust each other. To resolve the problems, this paper presents the blockchain-based trust and fair system and develops the smart contract of auction and transaction. The prototype system is implemented based on the Hyperledger Fabric. The experimental results prove the feasibility of the scheme.

Asymmetric Encryption

In the current cross-border electronic commerce (e-commerce) system, various document recording and authorization processes are cumbersome, record sharing efficiency is low, and identity verification is difficult. A method of asymmetric encryption technology combining Blockchain technology and cryptography is proposed. The advantages of asymmetric encrypted communications include high security and ease of multiparties communication collaboration, being applied to a peer-to-peer network formed by Blockchain technology, and making cross-border e-commerce record cross-domain sharing traceable, data immutable, and identity verification simplified. First of all, based on the immutable modification of Blockchain technology and asymmetric encryption technology, file synchronization contracts and authorization contracts are designed. Its distributed storage advantages ensure the privacy of users’ cross-border e-commerce information. Second, the design of the cross-domain acquisition contract can effectively verify the identity and transmission efficiency of both parties to the data sharing, so that illegal users can be safely filtered without a third-party notary institution. The simulation experiment results show that the solution proposed in this paper has obvious advantages in data antitheft, multiparty authentication, and saving system overhead compared with traditional cloud computing methods to solve the problem of sharing medical records. It provides a reference for solving the security problems in the process of data sharing by using the advantages of Blockchain’s decentralization and auditability and provides reference ideas for solving the problems of data sharing and cross-domain authentication.

In the field of modern bidding, electronic bidding leads a new trend of development, convenience and efficiency and other significant advantages effectively promote the reform and innovation of China’s bidding field. Nowadays, most systems require a strong and trusted third party to guarantee the integrity and security of the system. However, with the development of blockchain technology and the rise of privacy protection, researchers has begun to emphasize the core concept of decentralization. This paper introduces a decentralized electronic bidding system based on blockchain and smart contract. The system uses blockchain to replace the traditional database and uses chaincode to process business logic. In data interaction, encryption techniques such as zero-knowledge proof based on graph isomorphism are used to improve privacy protection, which improves the anonymity of participants, the privacy of data transmission, and the traceability and verifiable of data. Compared with other electronic bidding systems, this system is more secure and efficient, and has the nature of anonymous operation, which fully protects the privacy information in the bidding process.

Blockchain is a distributed ledger with the ability of keeping up the uprightness of exchanges by decentralizing the record among participating clients. The key advancement is that it enables its users to exchange resources over the internet without the requirement for a centralised third party. Also, each 'block' is exceptionally associated with the past blocks by means of digital signature which implies that creation a change to a record without exasperating the previous records in the chain is beyond the realm of imagination, in this way rendering the data tamper-proof. A semantic layer based upon a blockchain framework would join the advantages of adaptable administration disclosure and approval by consensus. This chapter examines the engineering supporting the blockchain and portrays in detail how the information distribution is done, the structure of the block itself, the job of the block header, the block identifier, and the idea of the Genesis block.

Cross-border transactions have been more and more popular around the world. However, the current cross-border transactions still have risks and challenges, e.g., differences in regulation policies and unbalanced profits of banks. To address this critical issue, we construct a new framework for the transaction system with the support of blockchain technology. In this paper, we propose a new consortium blockchain system, namely asymmetric consortium blockchain (ACB), to ensure the implementation of cross-border transactions. Different from traditional consortium blockchain, the new blockchain system could support the supernode to regulate all the transactions timely. Furthermore, the new smart contract is designed to lower the opportunity loss for each node and make the profits allocation system fairer. In the end, the numerical experiments were carried out based on the transactions of Shenzhen and Hong Kong. The results show that the proposed ACB system is efficient to make the profit allocation fairer for the participants and keep intelligent for the new cross-border transaction system.

This paper explores a potential paradigm shift in trade finance utilizing blockchain technology. Traditionally, the centralized operating model has governed trade finance and the manner in which traders handle business processes. However, such heavy reliance on centralized authorities has made for poor performance, the lack of flexibility and transparency, and vulnerability to malicious alteration. The blockchain, as a distributed ledger technology (DLT), has attracted growing attention and has the potential to disrupt legacy finance procedures such as payment by letter of credit (L/C). International trade players may benefit from the technological reengineering of financial processes through the implementation of blockchain- and smart contract-based platforms. From the conceptual perspective of a paradigm shift, this study analyzes the feasibility of blockchain innovation in trade finance through modern blockchain-based L/C initiatives. Moreover, this study also explores blockchain applications in terms of logistics tracking and how it integrates with trade finance procedures. This study contributes to the understanding of a blockchain paradigm shift with a multi-case study. The results may illuminate the potential future application of blockchain finance and provide researchers with an illustrative example of other finance-related capabilities. Studies of trade-related topics such as customs clearances, insurance, and logistics applications need to be addressed in the future to create a comprehensively trustless environment and facilitate the automation of trade.

Opening Phase

Traditional voting and bidding systems largely rely on paperwork and human resources throughout the voting process, which can incur high costs in terms of both time and money. Electronic voting and electronic bidding systems can be used to reduce costs, and many new systems have been introduced. However, most systems require a powerful and trusted third party to guarantee system integrity and security. With developments in blockchain technology, research has begun to highlight the core concept of decentralization. In this study, we introduce the first decentralized electronic voting and bidding systems based on a blockchain and smart contract. We also use cryptographic techniques such as oblivious transfer and homomorphic encryptions to improve privacy protection. Our proposed systems allow voters and bidders to participate in the opening phase and improve participant anonymity, the privacy of data transmission, and data reliability and verifiability. Moreover, compared with other electronic voting and bidding systems, our systems are safer and more efficient.
