The DAG structure facilitates scalability, which is one of the main challenges of decentralized technologies. The Coordinating network maintains a register of Validators, and also assigns block producers, committee members, and leaders in each time slot. In addition, the linearization and finalization of the distributed ledger are performed in the Coordinating network increasing overall security and synchronization.","PeriodicalId":186049,"journal":{"name":"2022 IEEE 1st Global Emerging Technology Blockchain Forum: Blockchain & Beyond (iGETblockchain)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114670350","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}

Unlocking the full and real potential of local energy markets is among the opportunities to be demystified in the coming years, with blockchain technology being a prominent enabler. Important subcomponents such as functional and fair local energy pricing mechanisms and management algorithms will be required for next-generation digital local energy trading and management platforms. Even though rapid digitalization of the energy sector offers considerable advantages, it also increases the cyber-physical risk levels of energy systems in general. The proposed framework of this paper accommodates considerable undiscovered aspects of democratization of the energy systems and future digital shared economy conventions. Nevertheless, privacy concerns must be addressed in tandem with the cyber-physical security of local energy markets and their ecosystem. This work proposes a joint privacy and cyber-physical security framework designed for local energy markets to improve cyber-physical resilience. All related parts, such as blockchain technology and self-sovereign identity, are used in an organized way to create a possible solution.","PeriodicalId":186049,"journal":{"name":"2022 IEEE 1st Global Emerging Technology Blockchain Forum: Blockchain & Beyond (iGETblockchain)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126626277","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 sharding was designed to resolve the problem of low processing rates, it also increases the scalability of the network. However, its effect on the probability of forking is still unclear. Our primary goal in this study is to determine the impact of adding new shards to a blockchain on the probability of forks occurring. In order to achieve this goal, we first developed a novel simulator which enables us to simulate sharded networks. Then, we examined the effect of sharding on fork occurrence. Two EIP-1559 enabled networks containing 60 and 120 nodes have been studied in several experiments. As a result of our study, we have found that adding one shard on average results in a 60% reduction in the number of orphan blocks. In addition, we have proposed a fork probability model which results in 23% and 15% reductions for networks with 60 and 120 nodes, respectively.","PeriodicalId":186049,"journal":{"name":"2022 IEEE 1st Global Emerging Technology Blockchain Forum: Blockchain & Beyond (iGETblockchain)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121427876","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}

Even though it has extensive literature, there is not enough research on healthcare supplier selection (HSS). Healthcare is a critical sector. Any decision made for it needs to be done scrupulously and transparently. Because if later something goes wrong, only responsible individuals should be held accountable. However, the existing system for HSS is not competent enough. Therefore, we need a decentralised system that extensively supports automation, transparency, traceability, data immutability and security. This paper proposes a blockchain-based decentralised platform for HSS. The features of a blockchain system, like immutability, transparency, traceability, blockchain-backed smart contract, etc., are leveraged for HSS. Smart contact is employed for safe, intermediary-free & hassle-free contractual work between the buyers and suppliers. Supplier selection is done using a Multi-Criteria Decision Making (MCDM) method because multiple criteria must be considered to assess a supplier.","PeriodicalId":186049,"journal":{"name":"2022 IEEE 1st Global Emerging Technology Blockchain Forum: Blockchain & Beyond (iGETblockchain)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126672529","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}

Indeed, Blockchains have already been applied to these domains to provide transparent and secure energy transactions between multiple parties without the involvement of intermediaries. However, standardization guidelines and roadmaps for the application of Blockchains to power grids and energy domains are urgently required. Standardization is one of the most important factors for the success of an emerging technology and requires the support of multiple groups including industry, academia, governments, and other interest communities to boost its sustainable development, interoperability, and ease of use. Several international standards organizations (IEEE, ISO, and ITU-T) have led the Blockchain technology and application standards development in recent years. This paper provides a comprehensive review of applications of Blockchains to the energy and power grid domains, and the standard development activities by the IEEE Standards Association (SA).

For instance, Benford's Law analysis can identify anomalies in the probability distribution of the leading digits of the entries in a numerical dataset. The anomalies can then be used for further analysis that leads to the exposure of privacy or business secrecy. In this paper, we propose a wallet design which randomly splits a payment value over multiple transactions in such a way that it is resistant to Benford's Law analysis, and therefore preventing any further analysis on the transaction data. We support our claim by providing a mathematical proof showing that the resulting distribution of the leading digits of the transaction values adhere closely to the Benford's Law, thus improving user privacy. Moreover, our design preserves accountability for any misbehaviour by creating an off-chain cryptographic link between a payment and its respective transactions which can be provided upon request during a legitimate audit.","PeriodicalId":186049,"journal":{"name":"2022 IEEE 1st Global Emerging Technology Blockchain Forum: Blockchain & Beyond (iGETblockchain)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134144228","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}

Furthermore, biological organisms function more resiliently than our most advanced machines, with a fraction of their power requirements. Taking inspiration from how primates and humans have successfully evolved higher cognitive intelligence within social constructs, this paper proposes neuromorphic systems to be built and governed on a public distributed ledger platform. However, following in the footsteps of generic AI research, neuromorphic benchmarks and algorithms are developed in isolation. Furthermore, as a relatively niche research field, there is limited access to the actual neuromorphic sensors and large publicly available curated data, exacerbating the slow research progress. Nonetheless, centralized neuromorphic datasets and algorithms pose a threat to secure closed-loop behavior and learning outcomes, both commonly modulated in biological organisms via social interactions. This paper makes the case for early adoption of distributed ledger technology by neuromorphic systems and benchmarks to avoid the pitfalls endured by AI research – showcasing competing event-based gesture recognition systems on the Ethereum smart contract platform. This shift towards real-world and dynamic systems on a distributed ledger platform will improve collaboration among neuromorphic researchers while enabling healthy competition via incentives. Smart contract protocols allow model behavior monitoring, setting new learning tasks and increase in baseline performance, and naturally provides a governance framework for evolving neuromorphic systems.

These sites operate mostly on the dark web and their main mission is launder bitcoins by making vast amounts of complex transactions with them and to make their association with a single owner even harder. Our mission is to make that distinction easier. In this paper we plan to introduce two novel heuristics. Our OI heuristic is designed to parse blockchain data in a way where we only receive information we deem is of interest. We introduce HOLO which aims to taint bitcoin addresses in reference to a fixed output.

We implemented this multilayer solution as a middleware service that uses Complex Event Processing on smartphones to efficiently record nearby place-specific beacons in a DLT.
