With the rapid growth of the Internet of Things (IoT) market and requirement, low power wide area (LPWA) technologies have become popular. In various LPWA technologies, Narrow Band IoT (NB-IoT) and long range (LoRa) are two main leading competitive technologies. Compared with NB-IoT networks, which are mainly built and managed by mobile network operators, LoRa wide area networks (LoRaWAN) are mainly operated by private companies or organizations, which suggests two issues: trust of the private network operators and lack of network coverage. This study aims to propose a conceptual architecture design of a blockchain built-in solution for LoRaWAN network servers to solve these two issues for LoRaWAN IoT solution.

The study proposed modeling, model analysis and architecture design.

The proposed solution uses the blockchain technology to build an open, trusted, decentralized and tamper-proof system, which provides the indisputable mechanism to verify that the data of a transaction has existed at a specific time in the network.

To the best of our knowledge, this is the first work that integrates blockchain technology and LoRaWAN IoT technology.

The purpose of this study is to focus on structured data provision and asset information model maintenance and develop a data provenance model on a blockchain-based digital twin smart and sustainable built environment (DT) for predictive asset management (PAM) in building facilities.

Qualitative research data were collected through a comprehensive scoping review of secondary sources. Additionally, primary data were gathered through interviews with industry specialists. The analysis of the data served as the basis for developing blockchain-based DT data provenance models and scenarios. A case study involving a conference room in an office building in Stockholm was conducted to assess the proposed data provenance model. The implementation utilized the Remix Ethereum platform and Sepolia testnet.

Based on the analysis of results, a data provenance model on blockchain-based DT which ensures the reliability and trustworthiness of data used in PAM processes was developed. This was achieved by providing a transparent and immutable record of data origin, ownership and lineage.

The proposed model enables decentralized applications (DApps) to publish real-time data obtained from dynamic operations and maintenance processes, enhancing the reliability and effectiveness of data for PAM.

The research presents a data provenance model on a blockchain-based DT, specifically tailored to PAM in building facilities. The proposed model enhances decision-making processes related to PAM by ensuring data reliability and trustworthiness and providing valuable insights for specialists and stakeholders interested in the application of blockchain technology in asset management and data provenance.

Describes how technology is rapidly changing the way information is distributed and paid for. Libraries face the risk that they will be cut from the loop that includes publishers and information consumers. Libraries must take an active role in experimenting with emerging technology and trends in the economics and distribution of information. If they do so, they stand to maintain their strong position as collection builders and organizers, and to continue their tradition of excellence in providing access to information for their users. Highlights a number of issues that need to be addressed as libraries make the transition from paper to digital: funding models, fee versus free use of information, and the infrastructure of digital economy. Explores the role that electronic money may have in those libraries in more depth.

The purpose of this study is to formulate the most probable future scenario for the use of blockchain technology within the next 5–10 years in the electricity sector based on today’s experts’ views.

An international, two-stage Delphi study with 20 projections is used.

According to the experts, blockchain applications will be primarily based on permissioned or consortium blockchains. Blockchain-based applications will integrate Internet of Things devices in the power grid, manage the e-mobility infrastructure, automate billing and direct payment and issue certificates regarding the origin of electricity. Blockchain solutions are expected to play an important big role in fostering peer-to-peer trading in microgrids, further democratizing and decentralizing the energy sector. New regulatory frameworks become necessary.

The Delphi study’s scope is rather broad than narrow and detailed. Further studies should focus on partial scenarios.

Electricity market participants should build blockchain-based competences and collaborate in current pilot projects.

Blockchain technology will further decentralize the energy sector and probably reduce transaction costs.

Despite the assumed importance of blockchain technology, no coherent foresight study on its use and implications exists yet. This study closes this research gap.

As part of the V.10 F programme financed by Service Technique de la Production Aeronautique (STPA), AEROSPATIALE and DASSAULT — BREGUET have joined forces to produce a single Falcon 10 wing entirely made of carbon fibre. This wing has just been sent from the AEROSPATIALE Company's Nantes factory to the Toulouse Aernautic Testing Centre. A second wing will also be built, but this time, by DASSAULT‐BREGUET Biarritz plant. The two wings will be used for static fatigue testing. The programme calls for another pair of wings, one to be made by each of the same firms. They will later be mounted to a Falcon 10 for flight testing.

Many recent social media posts and news may create a perception of big success in the use of blockchain for the real estate industry, land registration and protection of titles and property rights. A sobering outlook is crucial because misleading concepts may bury the whole idea of blockchain use. This paper aims to research the possibilities of blockchain and other distributed ledger technologies (DLT) and applicability of these technologies for different purposes in real estate, property rights and public registries.

This research is framed with policy studies and focuses on property rights, land registration regulatory framework and information and communication technologies innovations. The context of this paper is decentralization which has been developed in political science studies and the role of blockchain and DLT in it. Therefore, the provided analysis of blockchain and DLT is interdisciplinary research to interpret the facets of DLT technologies in the context of real estate and land title registration.

Permissioned and private DLT systems cannot be considered a significant evolutionary step in government systems. Blockchain, which is distinguished from permissioned systems as the technology of the immutable ledger that does not require authorities, is a new word in governance. However, this technology has some principal features that can restrain its implementation at the state level and thus require further research and development. The application of blockchain requires a proper architecture of overlaid technologies to support changes of outdated and mistaken data, address issues of digital identity and privacy, legal compliance and enforceability of smart contracts and scalability of the ledger.

This paper shows the constraints of the technology’s properties which were not explained before in the context of title rights and land registration even though technological limits are known in more specific technical sources. Along with the known benefits this meant to help to avoid misinterpretation of some DLT features by non-technical people. A multidisciplinary approach in analyzing the technology and laws helped to better understand what can and cannot be beneficial for public registries and the protection of property rights. The presented outcomes can be laid down as requirements for the technical protocols aimed at addressing the issues of DLT and public policies to put blockchain at the service of society.
