Abstract
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.
Highlights
Cloud computing is a popular paradigm of offering services over the Internet [1]
Cloud computing services are generally provided in three types: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) [2]
Due to the characteristics of resources in cloud computing, more and more researchers introduce the quality of service parameter and nonprice attributes into cloud resource auction system to solve allocation problems and transaction fraud problems
Summary
Cloud computing is a popular paradigm of offering services over the Internet [1]. With the development of Internet technology and virtualization technology, more and more enterprises and individuals outsource their workloads to cloud providers. Even if the auction platform has security and trust issues, it still charges a large fee for service as a middleman between cloud providers and users. References [10,11,12] mainly aim at trust problem in the cloud platform and design a credible service transaction method combined with blockchain. A blockchain-based cloud resource allocation framework is proposed in [14] Conspicuous feature, of this model, is the timed commitment scheme, state mechanism, and ladder payment to guarantee auction fairness and trade fairness. We combine blockchain and smart contract technology to propose a blockchain-based cloud resource auction scheme to ensure the security of bidding data and the fairness of cloud services.
