This architecture results in issues such as single point processing, storage, and failure. Blockchain technology has emerged to provide a promising solution for such issues. In this paper, we propose the block-supply chain, a new decentralized supply chain that detects counterfeiting attacks using blockchain and Near Field Communication (NFC) technologies. Block-supply chain replaces the centralized supply chain design and utilizes a new proposed consensus protocol that is, unlike existing protocols, fully decentralized and balances between efficiency and security. Our simulations show that the proposed protocol offers remarkable performance with a satisfactory level of security compared to the state of the art consensus protocol Tendermint.","PeriodicalId":250870,"journal":{"name":"Proceedings of the 1st Workshop on Cryptocurrencies and Blockchains for Distributed Systems","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126349118","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}

These innovations have tackled technical challenges that were unresolved until their appearance. Existing models of peer-to-peer systems need a revision to cover the spectrum of potential systems that can be now implemented as peer-to-peer systems. This work presents a framework to build these systems. It uses an agent-oriented approach in an open environment where agents have only partial information of the system data. The proposal covers data access, data discovery and data trust in peer-to-peer systems where different actors may interact. Moreover, the framework proposes a distributed architecture for these open systems, and provides guidelines to decide in which cases Blockchain technology may be required, or when other technologies may be sufficient.","PeriodicalId":250870,"journal":{"name":"Proceedings of the 1st Workshop on Cryptocurrencies and Blockchains for Distributed Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133173899","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 analysis looks beyond the immediate economic benefits and risks of blockchain technology to consider the broader implications for the individual and society. The possibility of creating and participating in different and multiple self-determined political and economic systems could mobilize how we instantiate ourselves as individuals and societies. Blockchain technology invites the possibility of making a social world with greater prominence of the values we apparently care about: freedom, trust, and dignity. There is a need for social structures that ensure and promote coexistence among diverse individuals and groups, particularly looking ahead to the possibilities of machine intelligence and space settlement. The hidden novelty and benefit of blockchain technology is serving as a tool for the design of smart city cryptopolises and cryptocitizen social structures. The bigger stakes of blockchain technology are the possibility of having new modes of social organization.","PeriodicalId":250870,"journal":{"name":"Proceedings of the 1st Workshop on Cryptocurrencies and Blockchains for Distributed Systems","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123240133","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}

Existing papers on transaction confirmation blocks for Bitcoin use implicit assumption of prompt spreading of Bitcoin blocks over the network (that is not always the case for the real world conditions). The newer publications with rigorous analysis and proofs of Bitcoin blockchain properties that take into account network delays provide asymptotic estimates, with no specific numbers for transaction confirmation blocks. We propose three methods for determination of required number of confirmation blocks for Bitcoin and GHOST on networks with delayed message delivery with different models that take into account the possibility of faster adversarial node syncronization. For the GHOST we propose the first (to our knowledge) strict theoretical method that allows to get required number of confirmation blocks for a given attacker's hashrate and attack success probability.","PeriodicalId":250870,"journal":{"name":"Proceedings of the 1st Workshop on Cryptocurrencies and Blockchains for Distributed Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131506598","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}

Our approach is grounded on federated consensus mechanisms, which promise data quality managed through computational trust and data replication, without a centralized authority. We perform our experimentation on the ground of the NIMBLE cloud manufacturing platform, which is designed to support growth of B2B digital manufacturing communities and their businesses through federated platform services, managed by peer-to-peer networks.

Smart contracts are decentralized rules that are stored on the blockchain and are executed on demand. Furthermore, smart contracts can interact with each other via message exchange to access data that are stored on them and to call each others' methods. In this paper, we propose a two-level hierarchical architecture that is composed of two types of smart contracts: custodian and client. A custodian contract can deploy on-demand client contract, access their data and call their methods to perform specific updates. Moreover, we develop a framework to allow client contracts to share common variables among all or partial group of the contracts, which may only be mutated by its creator, custodian contracts. We measure the performance of our proposal by developing the proposed contracts and deploying them on three popular testnets.","PeriodicalId":250870,"journal":{"name":"Proceedings of the 1st Workshop on Cryptocurrencies and Blockchains for Distributed Systems","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129605275","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 Cloud services provide some benefits, e.g., replacing high upfront costs for an IT infrastructure with a pay-as-you-go model, they also introduce serious concerns that are notoriously difficult to address. In essence, Cloud customers are storing data and running computations on infrastructures that they can not control directly. Therefore, when problems arise -- violations of Service Level Agreements, data corruption, data leakage, security breaches -- both customers and Cloud providers face the challenge of agreeing on which party is to be held responsible. In this paper, we review the challenges and requirements for enforcing accountability in Cloud infrastructures, and argue that smart contracts and blockchain technologies might provide a key contribution towards accountable Clouds.","PeriodicalId":250870,"journal":{"name":"Proceedings of the 1st Workshop on Cryptocurrencies and Blockchains for Distributed Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126429321","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 addition, their widespread industrial applications and the continuous introduction of cryptocurrencies are also stimulating the attention of the public opinion. The underlying structure of these technologies constitutes one of their core concepts. In particular, they are based on peer-to-peer networks. Accordingly, all nodes lie at the same level, so that there is no place for privileged actors as, for instance, banking institutions in classical financial networks. In this work, we perform a preliminary investigation on two kinds of network, i.e. the Bitcoin network and the Bitcoin Cash network. Notably, we analyze their global structure and we try to evaluate if they are provided with a small-world behavior. Results suggest that the principle known as 'fittest-gets-richer', combined with a continuous increasing of connections, might constitute the mechanism leading these networks to reach their current structure. Moreover, further observations open the way to new investigations into this direction.","PeriodicalId":250870,"journal":{"name":"Proceedings of the 1st Workshop on Cryptocurrencies and Blockchains for Distributed Systems","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126860549","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}

We evaluate HLF in a real production mesh network and in the laboratory. We quantify the performance, bottlenecks and limitations of the current implementation v1.0.
