It is crucial that we improve our energy management due to the ever-growing imbalance in demand-supply. The new wave in the energy sector is characterized by the three D's of decarbonization, decentralization, and digitalization. For a sustainable life, it is necessary that energy is tapped from alternative sources that are renewable to leave a minimal carbon footprint. To integrate different sources with the main power grid, we require two-way communication among them. This makes it indispensable that consumers are empowered to protect their privacy and make them the sole owners of their data. A good access control scheme would ensure security of data, and an efficient trading platform would ensure judicious use of the resources. Here, we propose a framework URJA with an access control scheme and an energy trading platform based on blockchain for a smart grid. The locally available renewable sources of energy are connected to the grid such that demand-supply is managed effectively without loss of efficiency and privacy. A customized consensus scheme based on trust ensures a quick operation in real-time.</p></div>","PeriodicalId":53141,"journal":{"name":"Blockchain-Research and Applications","volume":"3 4","pages":"Article 100090"},"PeriodicalIF":5.6,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096720922000318/pdfft?md5=f93fff7d32b2f201e9985069ca332052&pid=1-s2.0-S2096720922000318-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46443290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In cases where a fully trusted central point does not exist, it is difficult to obtain a trusted audit trail of a workflow when each individual participant is unaccountable to all others. We propose AudiWFlow, an auditing architecture that makes participants accountable for their contributions in a distributed workflow. Our scheme provides confidentiality in most cases, collusion detection, and availability of evidence after the workflow terminates. AudiWFlow is based on verifiable secret sharing and real-time peer-to-peer verification of records; it further supports multiple levels of assurance to meet a desired trade-off between the availability of evidence and the overhead resulting from the auditing approach. We propose and evaluate two implementation approaches for AudiWFlow. The first one is fully distributed except for a central auxiliary point that, nevertheless, needs only a low level of trust. The second one is based on smart contracts running on a public blockchain, which is able to remove the need for any central point but requires integration with a blockchain.</p></div>","PeriodicalId":53141,"journal":{"name":"Blockchain-Research and Applications","volume":"3 3","pages":"Article 100073"},"PeriodicalIF":5.6,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2096720922000148/pdfft?md5=acaeec002917db3fdf93808b9740c4f6&pid=1-s2.0-S2096720922000148-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46418558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The IoMusT is a new area emerging in industry and academy as an extension of the IoT to the musical domain. The IoMusT itself, as the IoT, is a distributed network of musical things, which are objects augmented with information and communication technologies serving a musical purpose. The IoMusT vision requires, above all, IoT features such as decentralization, seamless authentication, transparency, data integrity and privacy, and self-maintenance, as well as the musical domain features such as efficient handling of copyrights and speed of royalties payment. Such features can be brought by blockchain. In this paper, we investigate the integration of blockchain technology with the IoMusT, and we name such synthesis “Blockchain-based IoMusT”. We present a vision for this new paradigm in terms of the novel opportunities that are enabled, and we propose a set of application scenarios enabled by technological integration.
