“…Smart contract deploys bytecodes to Ethereum network through the transaction way, and a new smart contract account will be generated every time if it is successfully deployed. During deployment, the smart contract code written in the Solidity language is transformed into EVM bytecodes through smart contract compiler SOLC [ 32 ]. After that, smart contract is created through a transaction that contains key information such as the creator's account number, and the content and address of smart contract.…”

Nowadays, blockchain technology and industry has developed rapidly all over the world, which is inseparable from continuous innovation and improvement on smart contract technology. Therefore, by summarizing the working principle and application research status of blockchain smart contract, this paper analyzes the development and challenges of smart contract. Firstly, we introduce the model and operation principle of blockchain smart contract for the overall architecture, analyze the deployment process of smart contract with Ethereum, Hyperledger Fabric and EOSIO, and make a comparative analysis from the technical level. And taking Byteball, InterValue and IOTA platforms as examples, we introduce the deployment process and application potential for DAG-based blockchain smart contract. Additionally, we also summarize the application research of smart contract for international and Blockchain Oracle, and discuss its innovative application and development trend in the future. Secondly, we introduce the application status of smart contract with Ethereum and Hyperledger Fabric platforms from the aspects of financial transactions, Internet of things, medical applications, and supply chain, and further discuss EOS (enterprise operation system), Blockchain Oracle and other application fields. Furthermore, we introduce the application advantages and challenges to smart contract for industrial Internet from the fields of manufacturing, food industry, industrial Internet of things and industry 4.0. Finally, we discuss the challenges faced by smart contract with technical issues, analyzes the impact on large-scale applications and mining system on the sustainable development of smart contract, and looks forward to the future research direction of blockchain smart contract.

A Permissioned Blockchain-Based Energy Management System for Renewable Energy Microgrids

et al. 2021

Peer-to-peer (P2P) energy management is one of the most viable solutions to incentivize prosumers in renewable energy microgrids. As the application of blockchain expends from the finance field to energy field, blockchain technology provides a new opportunity for distributed energy systems. However, a distributed energy system based on blockchains allows any node in the whole network to read data. In many application scenarios, user privacy cannot be effectively protected, and there is a security problem that the attack cannot be traced. In this paper, we propose an energy management mode based on a permissioned blockchain for a renewable energy microgrid. The novel permissioned blockchain framework uses entity mapping with a unique identity for each enterprise, natural person, or device, in order to avoid ineligible participants to join the microgrid. Each peer entity keeps the transaction information index of the whole network, but only keeps its own specific transaction information, so they can retrieve the transaction information of other peer entities but cannot obtain the details without permission. Moreover, this model could avoid communication delays and promote plug-and-play due to the distributed nature of the permissioned blockchain. The performance of the proposed method is evaluated with a demonstration program which is designed and deployed on a Hyperledger Fabric permissioned blockchain. Simulation results show the feasibility of the proposed method, and the model is conducive to the protection privacy and P2P energy management for decentralized energy systems.

“…Blockchain technology has a distributed data structure which integrates security, reliability, and centralization, and can also be considered as the central support technology for digital currency (Cai, Du, Gan, Zhang, & Huang, 2018). It is a revolutionary innovation and may be capable of forming a new economic system which can be called the blockchain economy and which may fundamentally change our understanding of governance (Beck, Müller-Bloch, & King, 2018).…”

This study aims to explore the usage trends of blockchain technology in the G20 countries, with a particular focus on Saudi Arabia. As an emerging technology, blockchain is already being widely used in a number of industries including in the financial and supply chain sectors. For the purpose of this research, a questionnaire was developed to explore the adoption trends of blockchain technology in Saudi organizations. Saudi Arabia was chosen to be the case study for the research topic, as it is one of the largest oil producers in the world and holds the presidency of the G20 in 2020. The results of the study showed that some organizations in Saudi do not currently intend to implement blockchain technology and there is a lack of knowledge in some industries about this technology. Some of the obstacles preventing blockchain technology adoption were also identified.
