Using the already proven DevOps approach in this setting makes sense, as it can accelerate the general pace of software development and delivery, improve software quality, and increase overall productivity. However, there is currently a lack of guidance on a structured DevOps approach and a breakdown of the specifics in the context of blockchain-based software development. Therefore, we combined gray literature and DevOps application studies from pertinent GitHub projects to systematically investigate current practices and solution approaches for an efficient blockchain-oriented DevOps procedure. In this process, we elaborated procedural steps and related activities according to the main stages of Continuous Integration and Continuous Delivery. Our research shows that core DevOps concepts and activities are similar to other areas and are entirely possible with already established CI/CD solutions that orchestrate the right tools, with the difference that more rigorous testing and differentiated deployment practices are required due to the inherent immutability of blockchain.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"56 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":"123335362","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, sharing data poses challenges around privacy and accessibility, particularly in the event of disputes between stakeholders with a shared interest, such as a supply chain. Auditors currently rely on stakeholders' compliance in order to verify data. Malicious parties may falsify the data before passing it onto the auditor. Using supply chains as a case study we present BlockTorrent, a protocol to address these challenges and help facilitate data sharing between supply chain participants. BlockTorrent allows participants to securely share their data in near real-time with other participants without the risk of information leakage or allowing the falsification of data, whilst guaranteeing data availability for auditors. This is achieved using a novel combination of distributed storage and on-chain secret sharing. This paper provides an implementation and evaluation of BlockTorrent, highlighting its performance and a security discussion. Lastly, we provide a discussion on the privacy challenges that were considered when designing BlockTorrent.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"43 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114022445","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, due to the fact that the vehicle, Road-Side-Units (RSU), and Edge Server use wireless channels to communicate, the risk of leaking or falsifying information is greatly improved. We offer EIoVChain, a reliable registration and authentication, secure information sharing based on the IoV edge server blockchain schema with minimal latency and efficient storage to address these issues. EIoVChain works with a novel primary node allocation algorithm that selects primary nodes based on their decentralized trust and a block verification process that identifies the transaction's validity of that block. The consensus algorithm follows the practical Byzantine fault tolerance model (PBFT) which works even when opposing nodes are active in EIoVChain. We have implemented EIoVChain on Raspberry pi 4. Experimental results show that EIoVChain outperforms conventional solutions with 66% verification delay and 49% communication overhead.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"232 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":"114258240","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}

The review targeted papers focusing on blockchain applications, collecting data from a consumer perspective, and examining trust as an outcome variable. We excluded non-peer-reviewed papers written before 2008 or in languages other than English. Our search in 5 databases yielded 704 studies. 29 studies were retained for the full-text review and 5 studies were included after conflict resolution. The small number of studies retained for analysis highlights the need for further empirical research on consumer trust in blockchain technology. While blockchain remained a mysterious term for most consumers, trust was the main factor determining the use of blockchain applications. Additionally, interface design, service, and information quality, together with the platform's ability to allow consumers to investigate products using blockchain applications. Trust remains the central issue for blockchain as trust in this “trustless” system appears to be a prerequisite for actual use, creating a “trust paradox”. This systematic review on consumer trust in blockchain technology is the first to provide a preliminary synthesis of consumers' needs and expectations for blockchain developers and provides important directions for future research on blockchain applications.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"516 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":"123089858","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 traditional swarm robotic applications, where homogeneous robots are utilized, it is possible to replace a robot if it malfunctions, and it can be assumed that all robots are interchangeable. However, in many real-world applications spanning from search and rescue missions to future household robotic appliances, heterogeneous robots will need to work together with the other robots and human agents to achieve specific tasks. Nevertheless, no such system exists. Therefore, we propose a system that utilizes a token economy for robotic agents that makes agents responsive to token acquisition as an incentive for collaboration in achieving a given task. The economy enables the system to self-govern, even under Byzantine and adversarial settings. We further incorporate a novel subcontracting framework within a blockchain environment to allow the robotic agents to efficiently and cost-effectively perform complex jobs requiring multiple agents with various capabilities. We conducted a thorough evaluation of the system in a prototype warehouse application scenario, and the results are promising.","PeriodicalId":372721,"journal":{"name":"2021 IEEE International Conference on Blockchain (Blockchain)","volume":"7 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":"125156768","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}

Though, Bitcoin is not a fully anonymous environment, rather a pseudonymous one, accounting for a number of attempts to beat its anonymity using clustering techniques. There is, however, a recurring assumption in all the cited deanonymization techniques: that each transaction output has an address attached to it. That assumption is false. An evidence is that, as of block height 591,872, there are several millions transactions with at least one output for which the Bitcoin Core client cannot infer an address. In this paper, we present a novel approach based on sound graph theory for identifying transaction inputs and outputs. Our solution implements two simple yet innovative features: it does not rely on BTC addresses and explores all the transactions stored in the blockchain. All the other existing solutions fail with respect to one or both of the cited features. In detail, we first introduce the concept of Unknown Transaction and provide a new framework to parse the Bitcoin blockchain by taking them into account. Then, we introduce a theoretical model to detect, study, and classify, for the first time in the literature, unknown transaction patterns in the user network. Further, in an extensive experimental campaign, we apply our model to the Bitcoin network to uncover hidden transaction patterns within the Bitcoin user network. Results are striking: we discovered more than 30,000 unknown transaction DAGs representing money flows never observed before. To the best of our knowledge, the proposed framework is the only one that enables a complete study of the unknown transaction patterns, hence enabling further research in the field, for which we provide some directions.","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":"129303577","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}
