Blockchain is one of the disruptive technical innovation in the recent computing paradigm. Many applications already notoriously hard and complex are fortunate to ameliorate the service with the blessings of blockchain and smart contracts. The decentralized and autonomous execution with in-built transparency of blockchain based smart contracts revolutionize most of the applications with optimum and effective functionality. The paper explores the significant applications which already benefited from the smart contracts. We also highlight the future potential of the blockchain based smart contracts in these applications perspective.

With the increasing popularity of blockchain technologies in recent years, blockchain-based decentralized applications (DApps for short in this paper) have been rapidly developed and widely adopted in many areas, being a hot topic in both academia and industry. Despite of the importance of DApps, we still have quite little understanding of DApps along with its ecosystem. To bridge the knowledge gap, this paper presents the first comprehensive empirical study of blockchain-based DApps to date, based on an extensive dataset of 995 Ethereum DApps and 29,846,075 transaction logs over them. We make a descriptive analysis of the popularity of DApps, summarize the patterns of how DApps use smart contracts to access the underlying blockchain, and explore the worth-addressing issues of deploying and operating DApps. Based on the findings, we propose some implications for DApp users to select proper DApps, for DApp developers to improve the efficiency of DApps, and for blockchain vendors to enhance the support of DApps.Index Terms-decentralized applications, Ethereum, smart contract, empirical study • RQ1: How is the popularity of DApps distributed?We explore the popularity of DApps by the number of unique users, transactions, and transaction volumes, and compare categories of DApps. We also examine the change of popularity as time evolves. By answering this question, we can provide an overview of the DApp market for all stakeholders in the DApp ecosystem. • RQ2: Are there any common practices of developing DApps? We investigate whether DApps are open source and how smart contracts are organized in a DApp. By answering this question, we can reveal the development arXiv:1909.00939v1 [cs.SE]

“…If we instantiate those smart contracts previously, users have to use numerous meaningless addresses to interact with blockchains. Some deployment tools [19] or platforms [20,21] facilitate the deployment process. However, this process makes the instantiation details being exposed to the callers (smart contract author or its user) and forces the callers to use the addresses of smart contracts.…”

To Delay Instantiation of a Smart Contract to Save Calculation Resources in IoT

Smart contracts are required to be instantiated in the predeployed stage, which consumes computation resources from then on. It is a big waste in the blockchain whose nodes are composed of IoT devices, as those devices often have limited resources (such as limited power supplies or a limited number of processes to run). Meanwhile, IoT devices are heterogeneous and different smart contracts are required. If those smart contracts are instantiated previously, numerous meaningless addresses are required. In this paper, we propose to delay the instantiation of a smart contract when used and terminate it when not used, which is similar to the life cycle of a variable. Then, a new kind of variable (the wrapping variable) is used to hide details of the instantiation and the address. The smart contract is instantiated in the construction function of the wrapping variable, or even it is delayed to the time when there are requests for it. The smart contract terminates when the variable is out of its scope. Then, different instantiation methods are proposed. Finally, we perform the qualitative comparison between the proposed approach and the predeployment method, and it demonstrates that the proposed methods optimize the life cycle of the smart contract and save calculation resources.
