This platform is designed to allow decentralized transactions between anonymous users. Thus, the development of methods to identify user behavior profiles, keeping their identities anonymous, has the potential to leverage business on this platform. In this work, we investigate the use of machine learning to classify a user profile as professional or common based on the attributes of their transactions. This classification is challenging due to the small fraction of publicly labeled users in Ethereum and still the considerably smaller fraction of professional users. To conduct this investigation, we train models considering carefully balanced sets of transactions with labeled users. Our results show high performance models for the classification of profiles, achieving a performance greater than 90% for accuracy, precision, and other related measures. In addition, we have identified the most relevant features in transactions for this classification.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126838889","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}

This indicates that we need to build a scalable and secure identification system. A blockchain is effective to resolve global identifier conflicts and to prove the legitimacy of the identifiers. However, the blockchain replication cost may become a bottleneck when allocation requests increase. Here, we propose a blockchain-based scalable allocation system for a ubiquitous code (ucode), which is a standardized global numerical identifier. In our system, a registrar bundles ucode allocation requests into a single transaction to reduce the replication cost. Based on the blockchain data generated from the transaction, the owner of each ucode space can provide a proof to claim his ownership. The proof mechanism requires registrants to wait for receiving proof data from the registrar. We analyze the trade-off between the waiting time and ucode allocation scalability. We also compare our proposal with the conventional methods and find that the proposed method enables more registrants to claim ucode ownerships.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114698795","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}

Content authenticity, quality, and relevancy appear to be among the more significant challenges with traditional content platforms. A novel trend in the technology space known as blockchain has been found to address these challenges. The consensus protocols associated with blockchain provide many benefits over traditional mechanisms on the frontiers of privacy, security, and decentralization. However, while these protocols provide consensus on rewards and transactions, they do not fully address content quality. More specifically, the issues around equal voting power are often not entirely consistent regarding voting weight. In this paper, a novel Content Quality Assessment and Rewarding Mechanisms (CARM) is proposed to address the variables of content quality. The system uses CQ Score, a Content Quality Assessment Framework via the Ethereum Blockchain and Smart Contracts to ensure that user variables such as completeness, authenticity, and relevancy are used to qualify content quality.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130916314","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}

However, legacy systems built over decades using different technology stacks, make collaboration challenging and hinder efficiency. Distributed ledger technologies (DLTs) have been proposed as a trust and efficiency mechanism for several inter organisation collaborative tasks. They can reduce friction in operations and help achieve a more streamlined and unified public service infrastructure. However, most of the work are either based on theory or purely conceptual and lack implementation. In this paper, we elaborate on the design and implementation of a proof of concept (POC) of a blockchain based interoperability and data sharing system that allows PSOs to seamlessly collaborate and share information in real time. The POC is based on the Registration of Overseas Entities and Beneficial Owners (ROEBO) legislation in the UK and demonstrates interactions between Companies House UK and other PSOs in a hybrid blockchain setting.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130951291","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}
