Making Sense of Blockchain Applications:A Typology for HCI

Blockchain is an emerging infrastructural technology that is proposed to fundamentally transform the ways in which people transact, trust, collaborate, organize and identify themselves. In this paper, we construct a typology of emerging blockchain applications, consider the domains in which they are applied, and identify distinguishing features of this new technology. We argue that there is a unique role for the HCI community in linking the design and application of blockchain technology towards lived experience and the articulation of human values. In particular, we note how the accounting of transactions, a trust in immutable code and algorithms, and the leveraging of distributed crowds and publics around vast interoperable databases all relate to longstanding issues of importance for the field. We conclude by highlighting core conceptual and methodological challenges for HCI researchers beginning to work with blockchain and distributed ledger technologies

Using blockchain to create and capture value in the energy sector

The undergoing digital transition of the energy sector refers to the integration of decentralized ledger technologies and data-driven solutions that have the potential to truly revolutionize its ecosystem and business practices. The aim of a decentralized, inter connected and two-way interactive energy grid can be enabled by leveraging blockchain technologies. This research investigates how blockchain technology can create and capture value from data and the new business models applied in Web 3.0 and blockchain-based environments in the energy sector. A qualitative case study research design was conducted for primary data collection and pilot projects by the European Commission were used for secondary data collection. The analysis shows local energy communities as the main blockchain application in this sector, with adjacent applications such as P2P energy trading, smart contract & metering, carbon trading and grid management. The main benefits associated are transparency, integrity, grid automation and renewable energy sources promotion, and obstacles are mainly associated with the contrasting centralized design of the current energy systems. We conclude that value is created and captured through data provenance and transparency, data monetization and tokenization, and data sharing and collaboration in blockchain platforms. New business models include the decentralization and fusion between energy production and consumption, generating a new actor known as the prosumer. Fundamental to a successful implementation of local energy communities that allow energy and asset trading between peers.A transição digital do sector energético baseia-se na integração de tecnologias de registo descentralizadas e de soluções de tratamento de dados que têm o potencial de revolucionar o seu ecossistema. O objetivo de uma rede de energia descentralizada e interconectada em ambos os sentidos, pode ser concretizado através do recurso a tecnologias blockchain. Esta investigação analisa a forma como esta tecnologia pode criar e reter valor a partir de dados e dos novos modelos de negócio associados à Web 3.0 e a ambientes baseados em blockchain neste sector. Para a recolha de dados primários, foi efetuado um caso de estudo qualitativo. Para dados secundários foram analisados os projetos-piloto da Comissão Europeia. A análise demonstra que as comunidades locais de energia são a principal aplicação da blockchain, com aplicações adjacentes como trocas de energia P2P, contratos e contadores inteligentes, comércio de carbono e gestão da rede. Os principais benefícios associados são a transparência, a integridade, a automatização da rede e a promoção das fontes de energia renováveis. Os obstáculos estão principalmente associados à estrutura centralizada dos atuais sistemas energéticos. Concluímos que o valor é criado e capturado através da proveniência, transparência, monetização, tokenização e integração de dados em plataformas blockchain. Os novos modelos de negócio incluem a descentralização e a fusão entre a produção e o consumo de energia, gerando um novo elemento neste sector, o prosumer. Fundamental para uma implementação bem sucedida de comunidades locais de energia que permitam o comércio de energia e de ativos entre pares

Blockchain-based trust management and authentication of devices in smart grid

The digitalization of the power grid and advancement in intelligent technologies have enabled the service provider to convert the existing electrical grid into a smart grid. The transformation of the grid will help in integrating cleaner energy technologies with energy management to improve power network efficiency. Internet of things (IoT) and various network components need to be deployed to harness the full potential of the smart grid. Also, integrating intermittent renewable energy sources, energy storage, intelligent control of selected power-intensive loads, etc will improve energy efficiency. But deployment of this information and communication technologies will make the grid more vulnerable to cyber attacks from hackers. In this work, blockchain-based self-sovereign identification and authentication technique is presented to avert identity theft and masquerading. The proposed approach can minimize the chances of identity-based security breaches in the smart grid. This paper provides an overview of the model of identification and authentication of IoT devices in Smart Grid based on Blockchain technology. The Blockchain based implementation of identification and authentication of devices is proposed to validate the model in the distributed electrical energy network. The model is able to authenticate the device using Blockchain in a trusted model. The system works according to plan validating the authenticity of transaction in a node in log(n) time, which justifies presented result.publishedVersio

The Human Side of Digital Technology: Supporting the Inclusion of Refugees in Higher Education Through Blockchain-backed EQPR

The spectrum of digital technologies that impact Higher Education (HE) is broad. This study explores the potential of Blockchain (BC) technology in the personalized learning path creation and data exchange in the learning processes. The flexibilization of education and digitizing student data through Blockchain may contribute to a more inclusive and sustainable HE system. According to the EU, the Blockchain supports sustainability in four main aspects: cybersecurity, accountability, transparency, and traceability. These aspects are also a driver of social impact and a higher capacity to include disadvantaged groups, such as refugees. Therefore, it is essential to start a debate between scholars and professionals about how the actors in the HE system engage in a collective meaning-making effort to sustain the adoption, diffusion, and use of BC for HE. The paper focuses on the experience of CIMEA DiploMe and EQPR for the recognition of refugees' qualifications. Through a collective consensus-making and awareness-raising effort, the blockchain-backed EQPR could be perceived as a critical tool to foster inclusion within the HEIs and enhance their social outreach

Opportunities and Barriers to the Adoption of Blockchain-Based Games in an Online Gaming Company in Thailand

This research aims to explore potential opportunities and barriers related to the adoption of blockchain-based games in an online gaming company in Thailand. The identified opportunities are classified under the benefits framework proposed by Shang and Seddon [1], and the identified barriers are classified under the Technology-Organisation-Environment (TOE) framework. Based on the knowledge and experience of experts in the case company, all the opportunities and barriers are then assessed using the concept of Failure Mode and Effect Analysis (FMEA), which is further improved using the Analytic Hierarchy Process (AHP) by assigning a relative weight to each element of the FMEA before being used to find the priority number (PN). Next, the Pareto principle is applied to reveal the critical opportunities and barriers. As a result, a total of 21 critical opportunities are revealed and categorised into 5 dimensions: 4 operational opportunities; 3 managerial opportunities; 7 strategic opportunities; 4 infrastructure opportunities; and 3 organisational opportunities, and a total of 19 critical barriers are revealed and categorised into 3 dimensions: 7 technological barriers; 6 organisational barriers; and 6 environmental barriers. The TOWS matrix is then used to formulate possible strategies for the case company to exploit the opportunities and address the barriers to the adoption of blockchain-based games. As a result, a total of 7 SO, 12 ST, 5 WO, and 1 WT strategies are proposed. Based on the PNs and the interview with experts, a roadmap including short-, medium-, and long-term action plans is also developed to facilitate the adoption of blockchain-based games
