“…It supports B2B trading and facilitates direct manufacturer-customer transactions and payment services. Typically, SC applications of the blockchain technology include proof of origin and traceability [24,26], inventory and demand levels sharing [25] and enforcement of regulations for pharmaceutical [27] and food products [28].…”

A Distributed Ledger for Supply Chain Physical Distribution Visibility

et al. 2017

Supply chains (SC) span many geographies, modes and industries and involve several phases where data flows in both directions from suppliers, manufacturers, distributors, retailers, to customers. This data flow is necessary to support critical business decisions that may impact product cost and market share. Current SC information systems are unable to provide validated, pseudo real-time shipment tracking during the distribution phase. This information is available from a single source, often the carrier, and is shared with other stakeholders on an as-needed basis. This paper introduces an independent, crowd-validated, online shipment tracking framework that complements current enterprise-based SC management solutions. The proposed framework consists of a set of private distributed ledgers and a single blockchain public ledger. Each private ledger allows the private sharing of custody events among the trading partners in a given shipment. Privacy is necessary, for example, when trading high-end products or chemical and pharmaceutical products. The second type of ledger is a blockchain public ledger. It consists of the hash code of each private event in addition to monitoring events. The latter provide an independently validated immutable record of the pseudo real-time geolocation status of the shipment from a large number of sources using commuters-sourcing.

“…The proposed framework advocates this approach and can be used beyond the current SC physical distribution application. Some of the emerging applications that can benefit from this model include finance, government services [30,31], IOT (Internet of Things) [26] and regulation compliance [27].…”

“…This is likely due to its status as the first established blockchain platform supporting full fledged smart contracts. It's use cases span almost all sectors we looked at, including voting [71], taxation [74], and collaborative urban decisionmaking [5], [78] in government sector; research paper authoring collaboration [90], digital media rights protection [102] and lottery system [102] in education, culture, science and innovation sector; clinical trial process improvement [105], medical data sharing [110], [114], supply chain of drug [121] and food [124] in well-being, health and safety sector; collaborative business process [133], [134], product provenance [137], automated sales systems [139], and sharing economies [147], [148] in the economy sector; sustainable transportation [172] in the transportation sector; energy efficiency and peer-to-peer energy market [178]- [180], [183], [184], [187], [195], and electronic vehicle charging [204] in the energy sector; and building operation management access control [214] in the built environment sector. It should be noted that while Ethereum is a permissionless blockchain, most of the research prototypes are run on the test net or a separate private Ethereum network due to their early stage nature.…”

Blockchain for Cities—A Systematic Literature Review

2018

View full text Add to dashboard Cite

Blockchain is considered one of the most disruptive technologies of our time. Numerous cities around the world are launching blockchain initiatives as part of the overall efforts toward shaping the urban future. However, the infancy stage of the blockchain industry leads to a severe gap between the knowledge we have and the actions urban policy makers are taking. This paper is an effort to narrow this rift. We provide a systematic literature review on concrete blockchain use cases proposed by the research community. At the macro-level, we discuss and organize use cases from 159 selected papers into nine sectors recognized as crucial for sustainable and smart urban future. At the micro-level, we identify a component-based framework and analyze the design and prototypes of blockchain systems studied in a subset of 71 papers. The high-level use case review allows us to illustrate the relationship between them and the four pillars of urban sustainability: social, economic, environmental, and governmental. The system level analysis helps us highlight interesting inconsistencies between well-known blockchain applicability decision rules and the approaches taken by the literature. We also offer two classification methodologies for blockchain use cases and elaborate on how they can be applied to stimulate cross-sector insights in the blockchain knowledge domain.INDEX TERMS Bitcoin, blockchain, computer networks, consensus, crypto token, distributed computing, Ethereum, Hyperledger Fabric, systematic literature review, smart city, smart contract, system analysis and design, peer-to-peer computing, urban sustainability, use case.

“…Blockchain applications initially were limited to the cryptocurrencies and financial transactions. Invention of smart contracts leads to development of more divers applications [10], such as healthcare [5,14,42,52], IoT [16,21,38,41,46,47], supply chain [8,12,29]. In our previous study [43], after reviewing many research studies based on blockchain and smart contracts, we noticed that the primary focus of many presented applications is providing an efficient and secure access control mechanism.…”

Access control is a mechanism in computer security that regulates access to the system resources. The current access control systems face many problems, such as the presence of the third-party, inefficiency, and lack of privacy. These problems can be addressed by blockchain, the technology that received major attention in recent years and has many potentials. In this study, we overview the problems of the current access control systems, and then, we explain how blockchain can help to solve them. We also present an overview of access control studies and proposed platforms in the different domains. This paper presents the state of the art and the challenges of blockchain-based access control systems.
