The class of operations that span two or more DLTs is generally referred to as interledger. Various interledger approaches have been proposed, researched and taken into use, including for example, atomic cross-chain transactions, sidechains, bridging approaches, ledger-of-ledger structures, and layered value transfer protocols, such as the W3C Interledger Protocol (ILP).In this demonstration, we exemplify ongoing work in our research group at Aalto University. We demonstrate how a resource-constrained IoT device may be made able to interact with an “IoT-friendly” ledger, with an interledger gateway service bridging to a public permissionless ledger. The demo use case reflects a scenario where an IoT device advertizes a service that is available for anyone on the Internet, pending a successful and validated payment has been made on the Ethereum ledger. This demonstration shows how this can be accomplished in an auditable and secure manner across ledgers using hashed timelock agreements (HTLAs) to provide payment escrow.","PeriodicalId":314490,"journal":{"name":"2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC)","volume":"245 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115109658","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}

In the interactions with the full node, the lightweight client leaks considerable information about the Bitcoin transactions or addresses associated with this client. Therefore, the benefit of using lightweight client comes at costs of privacy. Existing solutions cannot support the lightweight client to retrieve the relevant transactions from the full node in an efficient and privacy-preserving way. In this paper, we propose a new approach to protect the privacy of lightweight clients in Bitcoin. Our main idea is to use private information retrieval (PIR) to guarantee that the lightweight clients can fetch the relevant transactions from untrusted full nodes without revealing to those nodes which particular transactions are being fetched. Directly using existing PIR scheme incurs high communication overhead for lightweight clients. Therefore, we propose an optimized protocol utilizing two-step PIR to efficiently retrieve the queried transactions without leaking sensitive query information. We developed a prototype implementation to demonstrate the feasibility of our proposed scheme.","PeriodicalId":314490,"journal":{"name":"2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130547942","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}

Contemporary IoT and enterprise deployments widely use the publish-subscribe messaging model because of its resource-efficiency. However, the systems with publish-subscribe messaging model employ a centralized architecture, wherein the data from all the publishers in the application network flows via a central broker to the subscribers. Such a centralized architecture makes the publish-subscribe messaging model susceptible to Byzantine failures. For example, it provides an opportunity for the organization that owns the broker to tamper with the data. In this work, we contribute Trinity, a novel distributed publish-subscribe broker with Byzantine fault-tolerance and blockchain-based immutability. Trinity distributes the data published to one of the brokers in the network to all the brokers in the network, and stores the data in an immutable ledger through the use of blockchain technology. Through the use of consensus protocols and distributed ledger technology, Trinity can guarantee ordering, fault-tolerance, persistence and immutability across trust boundaries.Our evaluation results show that Trinity consumes minimal resources. To the best of our knowledge, Trinity is the first framework that combines the components of the blockchain technology with the publish-subscribe messaging model. Furthermore, we plan to use Trinity in a real-world use case for increasing the transparency of racial profiling.","PeriodicalId":314490,"journal":{"name":"2019 IEEE International Conference on Blockchain and Cryptocurrency (ICBC)","volume":"15 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115576119","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}
