Radical changes in the technological environment have been forcing service providers to consider whether, if so, how to automate any aspects of their services with robots and other emerging technologies. Some service providers have been adopting robotic service assistants, and even creating organizations partially or fully automated by robots. However, some service providers have not been able to fully take advantage of RSAs’ benefits in a way that enhances customer service experiences. We review those challenges of RSAs and discuss the potential application of blockchain technology in governing a robotic service organization, the concept we propose in this study. Drawing on transaction cost theory and resource-based theory, we discuss theoretical implications of the impact of blockchain technology on the governance of a robotic service organization. Our study represents one of the first theoretical research to evaluate the impact of blockchain technology in a robotic service economy.

The digital finance revolution, which is often termed the “FinTech Revolution”, is currently changing the financial services industry through innovative solutions, often developed by startup and Big Tech companies. The financial sector is one of the key pillars of all economic transactions in general and sustainability specifically. As is so often the case: money is power. Innovative examples range from digital supply chain finance enabled agricultural and fashion value chains bridging Western and African as well as Asian countries, digital currency fueled smart meters for schools in Africa, digital investment marketplaces for forest tokens to crowdfunding enabled entrepreneurship in Asia and South America. Digital innovation in financial services is changing the way how financial resources can be accessed, distributed, and managed. This paper analyzes approaches from the emerging field of FinTech, InsurTech and blockchain at the intersection of sustainability. By reading through almost one-hundred and fifty papers from academia and practice as well as analyzing hundreds of start-ups in this field, the major building blocks were derived and a future research and innovation agenda was developed. The Appendix which is mentioned in this paper is downloadable online: www.sustainable-digital-finance.org. The results indicate that the topic is of great emerging interest. The areas of the focus are energy management, financial services, governments/NGOs, and transportation as well as some other relevant sectors that hold great potential and in which the combination of business and sustainability benefits is more obvious than ever enabled through innovative technology. The analysis reveals that future research and innovation areas might be fruitful in (1) novel ways for an integrated measuring of business and sustainability benefits, (2) novel sustainable cross-industry ecosystems and business models relying on new FinTech, InsurTech and blockchain enabled products and services, (3) new forms of organizational designs such as autonomous distributed organizations and processes built on new governance mechanisms and (4) novel FinTech, InsurTech, and blockchain applications for Sustainable Digital Finance Ecosystems.

Crowd intelligence has become increasingly popular during recent years, thanks to the exploding global Internet usage. However, most crowd intelligence platforms ceased to operate due to the untrustworthy data or lack of motivated participants. The blockchain technologies propose decentralization as the potential solution to this dilemma. This work introduces reciprocal crowdsourcing, a novel decentralized cooperative crowdsourcing model powered by the blockchain to strengthen trust among crowd intelligence participants, who perform transparent collaborative work in the system thereafter. To validate our proposal, we implemented “Cell Evolution”, a blockchain game, in which the players can build cooperative game worlds on the blockchain with reciprocal crowdsourcing.

New digital technologies are changing the way organizations create and capture value. In particular, blockchain is bringing up opportunities for organizations in terms of transparency and security, and at the same time threatening the position of intermediaries such as banks and notaries. Therefore, intermediaries need to design new business models to generate value from blockchain. Little academic re-search has been conducted to identify the business models that intermediaries could exploit to leverage a disintermediation technology such as blockchain. Employing a qualitative research based on focus group and interviews, this study highlights how a specific intermediary, the Italian notaries, tried to design appropriate business models to derive value from blockchain ecosystems. Specifically, drawing on the key concepts of value configuration, value creation and business model dimensions, this paper identifies three different business models that Italian notaries can implement to create and capture value from permissionless blockchain ecosystems.

As a new FinTech innovation regulation tool, regulatory sandbox effectively balances financial innovation and risk, so it is adopted by many regulatory authorities around the world. However, until now, regulatory sandbox is still at the stage of manually submitting data, and artificial intelligence has not been applied to it. Hence, in this paper, we propose the framework of Parallel FinTech Regulatory Sandbox based on the ACP approach (Artificial systems + Computational experiments + Parallel execution). Then, we talk about how to combine the emerging blockchain technology with intelligent regulatory sandbox, thus solving problems such as poor data flow and regulation sluggish. This paper is aimed at providing helpful guidance and reference for the development of FinTech regulatory sandbox.

Given the increasing interest in blockchain technology, we present a large-scale cross-disciplinary literature analysis of research on the blockchain using topic modelling with the goal of identifying the major research trends, research methodologies, and fruitful areas for further research. In particular, the analysis focuses on abstracting out research trends from relevant terms and topics related to the research disciplines of Business, Computer Science, Economics, Social Sciences, Engineering, Healthcare, and Law. A total of 2,125 articles published between 2008 to up until early 2019 in academic journals and conferences were analyzed. Results of our analysis reveal that research is bipartite between practical and research domains, with academic research on blockchain not clearly aligning with organizational and social benefits. Also, we found – 1) few inter-disciplinary publications, and 2) a small number of studies that use surveys, experiments, and case studies as their research method. Our findings also reveal that research on Blockchain in the social sciences and law is still in the embryonic stage, thus making it essential to develop more direct research efforts for Blockchain to thrive in all research disciplines.

ABSTRACT While the accounting profession determines the possible future impacts of blockchain, universities will need to prepare students for a career using the disruptive technology. This necessitates hands-on training to teach the basics of modeling a blockchain network. Hyperledger is an open source blockchain advancement initiative hosted by The Linux Foundation (IBM n.d.). Hyperledger Composer is a specific Hyperledger project that provides a framework and necessary tools to facilitate new blockchain development. This proposal walks students through three use cases with the outcome of (1) familiarizing them with IBM's Hyperledger Composer (a virtual playground in which they can experiment with numerous blockchains), (2) orienting them to the underlying code that drives blockchains, and (3) improving their technological agility by directing them to manipulate the code and observe the functional effects.

Safe and scalable dynamic autonomous data interaction between medical institutions can increase the number of clinical trial records, which is of great significance for improving the level of medical trial collaboration, especially for clinical decision-making with regard to rare diseases. Through a preset authorization access and consensus mechanism, consortium chain provides integrity and traceability management for medical clinical data. However, how to enable users have ownership of their own medical data and share their medical data safely and dynamically between different medical institutions remains an area of particular concern. To achieve dynamic communication between medical consortium chains, this paper proposes (i) a cross-chain communication mechanism by simplifying the heterogeneous node communication topology and (ii) the construction rules of the node identity credibility path-proof to carry out dynamic construction and verification of the path-proof for cross-chain transactions. In addition, the consensus of the cross-chain transaction is modeled as a threshold digital signature process with multiple privileged subgroups; thus, the intra-chain consortium consensus based on the verification node list is extended to the cross-chain consensus. A smart contract deployment and execution scheme based on rational node value transfer mechanism is proposed by analyzing the value transfer game between nodes. Experimental results showed that the proposed scheme can not only enable patients to share their records safely and autonomously in an authorized medical consortium chain within milliseconds but also realize dynamic adaptive interaction among heterogeneous consortium chains.
