  • The use of Blockchain to support sustainable supply chain strategy
    IOP Conference Series: Materials Science and Engineering, 2019
    Co-Authors: Joniarto Parung
    Abstract:

    This paper aims to identify, and analyze how the use of Blockchains technology can support sustainable supply chain management strategies. This support is seen from environmental, economic, and social aspects. In addition, it explains the various advantages of using Blokchain technology to reduce the use of transportation and other resources that have the potential to damage the environment. From an economic aspect, this technology has the potential to increase the efficiency of cost and time. Blockchain technology also has the potential to provide social benefits for the companies involved because of the increasingly good reputation of the organization. Three examples of implementation of the Blockchain in three different industries are also provided in this paper. This paper also points out the potential disadvantages of using this technology for supply chains that can threaten supply chain sustainability.

  • The merits of using Ethereum MainNet as a Coordination Blockchain for Ethereum Private Sidechains
    The Knowledge Engineering Review, 2020
    Co-Authors: Peter Robinson
    Abstract:

    Abstract A Coordination Blockchain is a Blockchain that coordinates activities of multiple private Blockchains. This paper discusses the pros and cons of using Ethereum MainNet, the public Ethereum Blockchain, as a Coordination Blockchain. The requirements Ethereum MainNet needs to fulfil to perform this role are analyzed within the context of Ethereum Private Sidechains, a private Blockchain technology which allows many Blockchains to be operated in parallel, and allows atomic crosschain transactions to execute across Blockchains. We found that Ethereum MainNet is best suited to storing long-term static data that need to be widely available, such as the Ethereum Registration Authority information. However, due to Ethereum MainNet’s probabilistic finality, it is not well suited to information that needs to be available and acted upon immediately, such as the Sidechain Public Keys and Atomic Crosschain Transaction state information that need to be accessible prior to the first atomic crosschain transaction being issued on a sidechain. Although this paper examined the use of Ethereum MainNet as a Coordination Blockchain within reference to Ethereum Private Sidechains, the discussions and observations of the typical tasks a Coordination Blockchain may be expected to perform are applicable more widely to any multi-Blockchain system.

  • The merits of using Ethereum MainNet as a Coordination Blockchain for Ethereum Private Sidechains
    arXiv: Cryptography and Security, 2019
    Co-Authors: Peter Robinson
    Abstract:

    A Coordination Blockchain is a Blockchain with the task of coordinating activities of multiple private Blockchains. This paper discusses the pros and cons of using Ethereum MainNet, the public Ethereum Blockchain, as a Coordination Blockchain. The requirements Ethereum MainNet needs to fulfil to perform this role are discussed within the context of Ethereum Private Sidechains, a private Blockchain technology which allows many Blockchains to be operated in parallel, and allows atomic crosschain transactions to execute across Blockchains. Ethereum MainNet is a permissionless network which aims to offer strong authenticity, integrity, and non-repudiation properties, that incentivises good behaviour using crypto economics. This paper demonstrates that Ethereum MainNet does deliver these properties. It then provides a comprehensive review of the features of Ethereum Private Sidechains, with a focus on the potential usage of Coordination Blockchains for these features. Finally, the merits of using Ethereum MainNet as a Coordination Blockchain are assessed. For Ethereum Private Sidechains, we found that Ethereum MainNet is best suited to storing long term static data that needs to be widely available, such as the Ethereum Registration Authority information. However, due to Ethereum MainNet's probabilistic finality, it is not well suited to information that needs to be available and acted upon immediately, such as the Sidechain Public Keys and Atomic Crosschain Transaction state information that need to be accessible prior to the first atomic crosschain transaction being issued on a sidechain. Although this paper examined the use of Ethereum MainNet as a Coordination Blockchain within reference to Ethereum Private Sidechains, the discussions and observations of the typical tasks a Coordination Blockchain may be expected to perform are applicable more widely to any multi-Blockchain system.

  • Blockchain at the Edge: Performance of Resource-Constrained IoT Networks
    IEEE Transactions on Parallel and Distributed Systems, 2021
    Co-Authors: Sudip Misra, Yogachandran Rahulamathavan, Anandarup Mukherjee, Arijit Roy, Nishant Saurabh, Muttukrishnan Rajarajan
    Abstract:

    The proliferation of IoT in various technological realms has resulted in the massive spurt of unsecured data. The use of complex security mechanisms for securing these data is highly restricted owing to the low-power and low-resource nature of most of the IoT devices, especially at the Edge. In this article, we propose to use Blockchains for extending security to such IoT implementations. We deploy a Ethereum Blockchain consisting of both regular and constrained devices connecting to the Blockchain through wired and wireless heterogeneous networks. We additionally implement a secure and encrypted networked clock mechanism to synchronize the non-real-time IoT Edge nodes within the Blockchain. Further, we experimentally study the feasibility of such a deployment and the bottlenecks associated with it by running necessary cryptographic operations for Blockchains in IoT devices. We study the effects of network latency, increase in constrained Blockchain nodes, data size, Ether, and Blockchain node mobility during transaction and mining of data within our deployed Blockchain. This study serves as a guideline for designing secured solutions for IoT implementations under various operating conditions such as those encountered for static IoT nodes and mobile IoT devices.

  • Visualization of Blockchain Data: A Systematic Review
    IEEE Transactions on Visualization and Computer Graphics, 2020
    Co-Authors: Natkamon Tovanich, Nicolas Heulot, Jean-daniel Fekete, Petra Isenberg
    Abstract:

    We present a systematic review of visual analytics tools used for the analysis of Blockchains-related data. The Blockchain concept has recently received considerable attention and spurred applications in a variety of domains. We systematically and quantitatively assessed 76 analytics tools that have been proposed in research as well as online by professionals and Blockchain enthusiasts. Our classification of these tools distinguishes (1) target Blockchains, (2) Blockchain data, (3) target audiences, (4) task domains, and (5) visualization types. Furthermore, we look at which aspects of Blockchain data have already been explored and point out areas that deserve more investigation in the future.

  • Visual Analytics for Monitoring and Exploration of Blockchain Data With a Focus on the Bitcoin Blockchain
    2018
    Co-Authors: Petra Isenberg, Christoph Kinkeldey, Jean-daniel Fekete
    Abstract:

    The goal of our work is to devise visual analytics techniques to deeply explore data stored on Blockchains. Given the novel data storage nature of Blockchains, they offer a unique opportunity to study the evolution of the stored data as well as data storage patterns. Opposed to most existing approaches that analyze the raw data we focus on aggregated measures. In particular, we analyze long-term activities and monitoring of activities that led to building the Blockchain. We currently focus on the Bitcoin Blockchain as the most popular Blockchain with a turbulent history.

  • Blockchain and supply chain management integration: a systematic review of the literature
    Supply Chain Management: An International Journal, 2019
    Co-Authors: Maciel M Queiroz, Renato Telles, Silvia H Bonilla
    Abstract:

    This paper aims to identify, analyse and organise the literature about Blockchains in supply chain management (SCM) context (Blockchain–SCM integration) and proposes an agenda for future research. This study aims to shed light on what the main current Blockchain applications in SCM are, what the main disruptions and challenges are in SCM because of Blockchain adoption and what the future of Blockchains holds in SCM.,This study followed the systematic review approach to analyse and synthesise the extant literature on Blockchain–SCM integration. The review analysed 27 papers between 2008 and 2018 in peer-reviewed journals.,Blockchain–SCM integration is still in its infancy. Scholars and practitioners are not fully aware of the potential of Blockchain technology to disrupt traditional business models. However, the electric power industry seems to have a relatively mature understanding of Blockchain–SCM integration, demonstrated by the use of smart contracts. Additionally, the disintermediation provided by Blockchain applications has the potential to disrupt traditional industries (e.g. health care, transportation and retail).,The limitations of this study are represented mainly by the scarcity of studies on Blockchain–SCM integration in leading journals and databases.,This study highlights examples of Blockchain–SCM integration, emphasising the need to rethink business models to incorporate Blockchain technology.,This study is the first attempt to synthesise existing publications about the Blockchain–SCM integration, shedding light on the disruption caused by, and the necessity of, the SCM reconfigurations.
