“…The communication among the nodes in the blockchain is achieved by consensus protocols such as PoW, PoS, and Delegated Proof of Stake (DPoS), whereas, thanks to smart contracts, communication of blockchain with external data sources (oracles) is achieved to execute predefined conditions. Oracles ensure that the smart contract interacts with the real world and receives reliable data [192,193].…”

The Internet of Drones (IoD) is a decentralized network linking drones’ access to controlled airspace, providing high adaptability to complex scenarios and services to various drone applications, such as package delivery, traffic surveillance, and rescue, including navigation services. Unmanned Aerial Vehicles (UAVs), combined with IoD principles, offer numerous strengths, e.g., high mobility, wireless coverage areas, and the ability to reach inaccessible locations, including significant improvements such as reliability, connectivity, throughput, and decreased delay. Additionally, emerging blockchain solutions integrated within the concept of the IoD enable effective outcomes that surpass traditional security approaches, while enabling decentralized features for smart human-centered applications. Nevertheless, the combination of the IoD and blockchain faces many challenges with emerging open issues that require further investigation. In this work, we thoroughly survey the technological concept of the IoD and fundamental aspects of blockchain, while investigating its contribution to current IoD practices, the impact of novel enabling technologies, and their active role in the combination of the corresponding synergy. Moreover, we promote the combination of the two technologies by researching their collaborative functionality through different use cases and application fields that implement decentralized IoD solutions and highlighting their indicative benefits, while discussing important challenges and future directions on open issues.

“…So, to reach consistency, a consensus algorithm should be used. Various types of consensus algorithms had been developed with different mechanisms such as Proof of Work (PoW) [27], Proof of Stake (PoS) [28], Delegated Proof of Stake (DPoS) [29], and Practical Byzantine Fault Tolerance (PBFT) [30]. Table 1 presents a comparison between these four consensus algorithms based on their representative cryptocurrencies and the blockchain trilemma in them.…”

Cooperative Mining System to Improve Bitcoin Scalability

Blockchain is a Distributed Ledger Technology (DLT) that allows users to exchange values directly without a need for trusted third parties. Bitcoin is one of the most popular digital cryptocurrencies that is based on blockchain technology. However, it faces scalability problems including transaction throughput, latency, and starvation. Bitcoin transaction throughput is very low compared to traditional payment methods. Additionally, many Bitcoin transactions suffer from delays and starvation as miners prefer transactions with higher fees. More of the current research focuses on how to enhance Bitcoin scalability by improving the performance of consensus techniques, dividing the network into smaller ones with different parts of the blockchain, or completely changing the blockchain data structure. Unfortunately, engaging in this problem usually affects either decentralization or security; this is called the blockchain trilemma. This paper proposes the Cooperative Mining System (CMS), which depends on enhanced proof of work consensus algorithm. This proposed system increases transaction throughput and eliminates transaction latency and starvation without affecting decentralization and security. In CMS for each epoch, miners cooperated to create one super-block that contains more transactions than the traditional Bitcoin block. Whereas miners create their traditional blocks simultaneously, broadcast them, wait to receive other miners' blocks, and lastly create a super-block that contains all the transactions of the gathered blocks. The Simulation results of the CMS and Bitcoin system using different case scenarios show a significant improvement in CMS compared to the current Bitcoin system. The CMS greatly increases the transaction throughput and eliminates transaction latency and starvation.

With significant use in the last few years, Blockchain has become one of the most important technologies of the last decade. Due to its new paradigm and its decentralized approach, Blockchain has become a game changer in almost all business domains. Water resources management is one of the areas that were updated with these new concepts. The aim of this paper is to present a decision support system, developed on top of the Ethereum Blockchain infrastructure which would facilitate the supplier`s internal flows related to the water network incident management and validation. The proposed solution integrates the following technology stacks: Cyber-Physical Systems, Crowd-Sensing, and Serious Gaming. This solution was implemented so as to work autonomously for some specific flows and take decisions by itself based on some specifically defined criteria and also to provide suggestions to validators and speed up the validation flows based on data stored exclusively on Blockchain.
