Principles of Corporate Finance - 4/E

Blockchain is a technology with unique combination of features such as decentralized structure, distributed notes and storage mechanism, consensus algorithm, smart contracting, and asymmetric encryption to ensure network security, transparency and visibility. Blockchain has immense potential to transform supply chain (SC) functions, from SC provenance, business process reengineering to security enhancement. More and more studies exploring the use of blockchain in SCs have appeared in recent years. In this paper, we consider a total of 178 articles and examine all the relevant research done in the field associated with the use of blockchain integration in SC operations. We highlight the corresponding opportunities, possible societal impacts, current state-of-the-art technologies along with major trends and challenges. We examine several industrial sectors such as shipping, manufacturing, automotive, aviation, finance, technology, energy, healthcare, agriculture and food, e-commerce, and education among others that can be successfully revamped with blockchain based technologies through enhanced visibility and business process management. A future research agenda is established which lays the solid foundation for further studies on this important emerging research area.

Utilizing data center waste heat in district heating – Impacts on energy efficiency and prospects for low-temperature district heating networks

In this study the potential for data center waste heat utilization was analyzed in the Nordic countries. An overview of upcoming data center projects where waste heat is utilized is presented. Especially in Finland data center operators are planning to reuse waste heat in district heating. However, business models between the district heating network operator and data center operator are often not transparent. The implications of economics and emissions on waste heat utilization in district heating were analyzed through life cycle assessment. Currently the biggest barriers for utilizing waste heat are the low quality of waste heat (e.g. low temperature or unstable source of heat) and high investment costs. A systematic 8-step change process was suggested to ensure success in changing the priority of waste heat utilization in the data center and district heating market. Relevant energy efficiency metrics were introduced to support rational decision-making in the reuse of waste heat. Economic calculations showed that the investment payback time is under the estimated lifetime of the heat pump equipment, when waste heat was utilized in district heating. However, the environmental impact of waste heat utilization depends on the fuel, which waste heat replaces.

Future views on waste heat utilization - case of data centers in Northern Europe

The 200-billion-dollar per annum online advertising ecosystem has become infested with thousands of intermediaries exploiting user data and advertising budgets. All key stakeholders in the value-chain are infected: advertisers with fraud, publishers with their diminishing share of advertising budgets, and users with their right to privacy. Blockchain presents a possible solution to addressing the critical issues in the online advertising supply chain. The question remains whether blockchain scalability, energy-efficiency, and token volatility issues can be solved in the coming years to the extent that online advertising could widely leverage trustlessness and the benefits gained from blockchain technology. This paper aims to review the current progress and to open a discussion to address the issues. We present new requirements for blockchain-based online advertising solutions. We have also analyzed the available solutions against the requirements and recommend directions for future research and solution development. Evidence from our research points out that blockchain is not yet ready to be widely implemented in online advertising. More research is needed, and new proof-of-concepts need to be developed before blockchain technology can be considered a trusted alternative for the current online advertising marketplace based on open real-time bidding.
