Security Analysis on the Decentralized Energy Trading System Using Blockchain Technology

Blockchain turns both currencies and commodities into a digital form without relying on middleman which allows one person to trade with another include trading the renewable energy. Blockchain technology as a secure and low-cost platform to track the billions of eventual transactions in a distributed energy economy has attracted the attention of experts in various fields of science. The current form of centralized energy trading system is still suffering from security concerns, quality of service, and to name a few. A decentralized energy system using blockchain technology allows the parties to create a trading energy transaction via microgrid. The blockchain technology offers the promise of an immutable, single source of truth from multiple sources without a third-party involvement. In this paper, we describe, explore and analyze the prominent implementation of blockchain technology in the energy sector. Furthermore, we analyze the security issues and highlight the performance of several attacks that might be occurred in the proposed system

A structured framework to assess the business application landscape of blockchain technologies.

Blockchain is emerging as a game changing technology in many industries. Although it is increasingly capturing the business community’s attention, a comprehensive overview of commercially available applications is lacking to date. This paper aims to fill this gap. Firstly, we propose a structured approach to assess the application landscape of blockchain technologies. To build our framework, we relied on largely accepted classifications of blockchains, based on protocols, consensus mechanisms and ownership, as well as on the most cited application areas emerging from the literature. Secondly, we applied the framework on a database of 460 released blockchains. The analysis confirms a dominance of applications for cryptocurrencies, financial transactions and certification purposes, with a prevalence of permissionless platforms. We also found new application fields that go far beyond the seven initial areas addressed by the current body of knowledge, leading to some interesting takeaways for both practitioners and IS researchers

Privacy and Transparency in Blockchain-based Smart Grid Operations

In the past few years, blockchain technology has emerged in numerous smart grid applications, enabling the construction of systems without the need for a trusted third party. Blockchain offers transparency, traceability, and accountability, which lets various energy management system functionalities be executed through smart contracts, such as monitoring, consumption analysis, and intelligent energy adaptation. Nevertheless, revealing sensitive energy consumption information could render users vulnerable to digital and physical assaults. This paper presents a novel method for achieving a dual balance between privacy and transparency, as well as accountability and verifiability. This equilibrium requires the incorporation of cryptographic tools like Secure Mul- tiparty Computation and Verifiable Secret Sharing within the distributed components of a multi- channel blockchain and its associated smart contracts. We corroborate the suggested architecture throughout the entire process of a Demand Response scenario, from the collection of energy data to the ultimate reward. To address our proposal’s constraints, we present countermeasures against accidental crashes and Byzantine behavior while ensuring that the solution remains appropriate for low-performance IoT devices
