The normal expectation is that, when the switch is thrown, the lights come on—each and every time. Outstanding availability and reliability are expected of the system. Other than a couple of wires running from a telephone pole to the house or, perhaps, an underground cable from a box at the side of the street, just what is the power grid, and what is its history?","PeriodicalId":39514,"journal":{"name":"IEEE Potentials","volume":"42 1","pages":"49-51"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44244091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While deploying an application to a blockchain network brings significant development overhead, the level of decentralization and security offered by permissionless blockchain systems has triggered a huge interest in the technology and a high demand for using existing networks. This increased demand has highlighted the most significant problem of public blockchain systems, scalability in terms of the transaction processing rate. The first generation of blockchain systems is characterized by very low transaction processing rates that, in combination with high usage demand, trigger high latency and high usage fees.","PeriodicalId":39514,"journal":{"name":"IEEE Potentials","volume":"41 1","pages":"26-31"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43909533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bitcoin inspired the launch of several other cryptocurrencies. Bitcoin set the stage for a new field called blockchain, which is a special case of distributed ledger technology (DLT). In 2015, programmable blockchain/DLT projects, such as Ethereum, Hyperledger Fabric, and R3 Corda, were launched. Over the last decade, blockchain/DLT has evolved to encompass a collection of distributed computer network architectures implementing various data structures, decentralized consensus protocols, and economic incentive models. In this rapidly emerging field, some remarkable innovations, experimentations, and developments have been carried out by start-ups, enterprises, and governments. This article will highlight various current and future applications of this technology.","PeriodicalId":39514,"journal":{"name":"IEEE Potentials","volume":"41 1","pages":"6-12"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42032425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the contrary, blockchain technology is thought to be expensive in terms of resource consumption due to the consensus procedures involved. As a result, the application of blockchain to the IoT environment is a challenging task. The most appropriate solution lies in replacing the computationally heavy consensus algorithms with lightweight counterparts. Proof of authentication (PoAh) is the most suited replacement for such an environment. Several modifications have been proposed for PoAh during the last few years, and they are reviewed here.","PeriodicalId":39514,"journal":{"name":"IEEE Potentials","volume":"41 1","pages":"38-42"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43635938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
