“…REC is strategic way of tracking and trading renewable energy production in current time. To produce a single renewable energy certificate, a 1.0MWh of renewable energy must be produced [4] [5] . Conventionally, REC is tradable on the energy market and customers who buy RECs adopt the renewable attributes of its and even the type and source of renewable energy generation.…”

Blockchain and the Internet of Things (IoT) complements each other within the space of decentralization, real time monitoring, and data sharing and security. In this paper we explored the integration of blockchain and IoT within the context of smart grid. Current REC system lacks visibility and transparency which are very critical to the success of smart grids. Conventional smart grid system makes it difficult to proof whether a buyer has truly received an energy certificate or not. Therefore, we proposed a blockchain and IoT based system for autonomous monitoring of energy sources and tracking of RECs on smart grid. Our system provides the visibility and transparency on smart grid networks that is imperative to safeguarding RECs market. Results based on extensive experiments illustrate the efficiency and scalability of our system.

“…In files known as "blocks", a series of time-ordered transactions are stored [37]. Each block includes the preceding block's hash value, and they ultimately form a hash sequence known as "blockchain", which is effectively an open, unchangeable, as well as orderly distributed ledger [38]. System users contend for the opportunity to record transactions into the blockchain by offering computer power, and the winner is paid by giving coins along with service fees.…”

ExCrowd: A Blockchain Framework for Exploration-Based Crowdsourcing

Because of the rise of cryptocurrencies and decentralized apps, blockchain technology has generated a lot of interest. Among these is the emergent blockchain-based crowdsourcing paradigm, which eliminates the centralized conventional mechanism servers in favor of smart contracts for task and reward allocation. However, there are a few crucial challenges that must be resolved properly. For starters, most reputation-based systems favor high-performing employees. Secondly, the crowdsourcing platform’s expensive service charges may obstruct the growth of crowdsourcing. Finally, unequal evaluation and reward allocation might lead to job dissatisfaction. As a result, the aforementioned issues will substantially impede the development of blockchain-based crowdsourcing systems. In this study, we introduce ExCrowd, a blockchain-based crowdsourcing system that employs a smart contract as a trustworthy authority to properly select workers, assess inputs, and award incentives while maintaining user privacy. Exploration-based crowdsourcing employs the hyperbolic learning curve model based on the conduct of workers and analyzes worker performance patterns using a decision tree technique. We specifically present the architecture of our framework, on which we establish a concrete scheme. Using a real-world dataset, we implement our model on the Ethereum public test network leveraging its reliability, adaptability, scalability, and rich statefulness. The results of our experiments demonstrate the efficiency, usefulness, and adaptability of our proposed system.

“…For individual solutions in smart cities, Guo et al [17] proposed a blockchain-based electricity-trading ecosystem. Asamoah et al [18] proposed several digital city management methods to secure individual residents' identifications with a blockchain for key management. Regarding UAV-assisted wireless networks with blockchains, Jiao et al [19] proposed a stability-aware consensus protocol for providing resource-sharing services in mobile ad hoc networks, Khan et al [20] investigated outsourcing network coverage of a specific area using blockchains and auction mechanisms, and Lei et al [21] proposed a systematic framework that integrates interest-key-content binding, forwarding strategy, and on-demand verification to discover poisoned content for UAV-IC ad hoc networks.…”

Secure Caching Scheme Using Blockchains for Unmanned Aerial Vehicle-Assisted Information-Centric Wireless Sensor Networks

This paper proposes a caching data protection scheme that uses blockchains and hashchains for unmanned aerial vehicle (UAV)-assisted information-centric wireless sensor networks in smart-city applications as a case study. In the consensus scheme of the proposed scheme, a new block is verified according to voting by validators without exhaustive mining computations. Therefore, the proposed scheme is suitable for resourcelimited wireless and mobile devices. With the scheme, UAVs work as validators as well as data collectors, and the overhead of transaction-fee management can be eliminated. Validators are responsible for block verifications; thus, the proposed scheme maintains the consensus by detecting and removing validators that vote incorrectly by using hashchain-based signatures. Simulations were conducted to evaluate the proposed scheme, and the results revealed the requirements for implementing it in smart-city applications and its robustness, feasibility, and effectiveness.
