The earth trembles before cryptocurrencies; but how does a blokchain-based smart money platform perform?Isaac, Andreas, Kakavandy, Shahow January 2018 (has links)
The Swedish central bank has in 2018 launched an investigation into what a digital e-currency in Sweden would look like. Tendermint is being investigated for a potential implementation. Tendermint is a blockchain building environment which has its own consensus-algorithm, and its own solution to the Byzantine general's problem. The most relevant part is the scalability and reliability of Tendermint. To do this we tested out the software by sending transactions between our computers, and recorded its performance in the case of one node and two nodes. After a series of simulations, we then come to the conclusion that indeed Tendermint is a suitable software for a potential e-krona.

Micropayments through cryptocurrency miningTigerström, Viktor January 2016 (has links)
The monetary policies of states and systems built upon them do not naturally allow transactions of a very small value, as the transaction costs exceeds the actual value of the transaction. These types of transactions are called micropayments. This is problematic as it removes the possibility to monetize content that has a valuation that is so low that the costs of the transaction exceeds the value of the content. In this thesis we aim to create a system that allows micropayments to monetize low value content. We do so by developing a design theory based on Gregor and Jones conceptual model for design theories within Information Systems research. The system that we develop will use the end users computational power to generate a value, by running a cryptocurrency miner. We present the background knowledge required to fully understand the presented design theory. Within the design theory, we present a theoretical framework to base systems on that enables micropayments through cryptocurrency mining. We also present a developed proof of work prototype that proves the validity of the theoretical framework. Lastly we discuss our design theory. We conclude that the design theory enables transactions of a very low value, such as 0,0001 \$ cents. Transactions of such small value is not possible with systems built upon states monetary policies. We also conclude that the proposed design theory can be further developed to function independently of cryptocurrency mining. Instead the value for the transaction could be generated through solving complicated problems if institutions are willing to pay for computational power to solve them.

The taxonomy of Crowdfunding - An actualized overview of the development of internet crowdfunding modelsTillberg, Fredrik January 2019 (has links)
Crowdfunding challenges century long boundaries between the public, the industry andinnovation. In that respect the phenomenon holds the potential to decentralize and democratizethe way ventures are financed and realized. Crowdfunding has seen a lot of exitingdevelopments during the last few years, partly because of new crowdfunding platformsemerging on the internet, and partly because of new ground-breaking technology being used forfunding purposes. Meanwhile research has not quite catched up with the recent developments ofdifferent models for crowdfunding. This study’s aim is therefor to give an comprehensiveoverview of the different models of crowdfunding that are being utilized by crowdfundingplatforms on the internet today. A deductive content analysis has been made of 67 currentcrowdfunding platforms. The platforms have been analysed in order to determine what model ofcrowdfunding they utilize. The result has, apart from partly confirming prior studies, alsoproduced new exiting findings on what mechanisms constitute some of the crowdfundingmodels we see today. A new taxonomy of crowdfunding models is discussed and proposed. Theconclusion is that the need for a updated taxonomy, like the one this study provides, was wellneeded in order to understand the field. One important finding is that blockchain technology hasproduced a new form of crowdfunding through cryptocurrency: Initial coin offering. Thatparticular area will likely develop and continue to decentralize and democratise the economicalhuman interaction when it comes to financing.

Information Sharing and the Bullwhip Effect Reduction : A new Prespective Through the Lens of Blockchain TechnologyAl-Sukhni, Muthana January 2023 (has links)
Globalization and the surge of competition across industries forced companies to improve their supply chain capabilities to serve their customers efficiently and effectively. Due to this fact, businesses are no longer capable of handling all supply chain operations without collaboration and coordination with other firms. One of the key obstacles to coordination is the lack of information sharing and trust between firms since they view information as a sensitive asset. Digital technologies like blockchain, with its inherited features, have the capability to facilitate real-time information sharing, solve trust issues, and improve end-to-end visibility across the supply chain. This licentiate thesis highlights the impact of multiple aspects of information sharing on the bullwhip effect mitigation and explores the potential of blockchain technology as a new coordination mechanism for reducing information distortions, enhancing trust, and orchestrating decision making. Three research papers have been produced within this context and are appended to the thesis. Paper A presents an information sharing-based blockchain architecture to mitigate the bullwhip effect in service supply chains. Paper B aims to explores the literature in terms of using multiple aspects of information sharing to lessen the bullwhip effect. Finally, Paper C introduces an agent-based modeling and simulation approach for two aspects of information sharing: “what to share” and “how to share.” The results show that blockchain technology does provide a significant solution to trust-based issues and information sharing visibility considering the bullwhip effect mitigation. The results also provide a guide for supply chain managers to achieve better coordination and serve as a roadmap for supply chain researchers.

Investigating the Adoption of Blockchain Technology for Cross-Border Payments in the Swedish Financial Industry : A Diffusion Theory Approach through Expert InterviewsIjeh, Dion, Puji Rahayu, Indah January 2023 (has links)
The adoption of blockchain technology for cross-border payments is not an easy task.However this qualitative study further investigates the connotations associated with adoptionof blockchain in cross-border financial transactions within Swedish financial institutions suchas banks, fintech, and credit management service companies. To answer this question, weinterviewed six participants that work in a credit management company, an open bankingcompany, and a digital mortgage service company using semi-structured interviews. Datacollection was done using this method because the purpose of this research work is to identifypeople's insights and experiences based on their real-life experiences. Data were analyzedusing thematic analysis. Our results showed that the impact of adoption of blockchain incross-border payment transactions in terms of technical implementation challenges,customers' use cases and pilot programs, compliance and security enhancements, industrycollaboration and knowledge sharing, legacy systems integration and interoperability, and keydrivers beyond adoption. In addition, the study findings were compared with the determinantsand influence factors of the model through the lens of the DOI. The implications of this studycould used to help financial institutions' focus on blockchain adoption in cross-borderpayment transactions. As a whole, this study contributes to the idea that financial institutionsshould develop an accurate strategy, as well as guidelines that can assist them in leveragingblockchain technology for cross-border payments, enhancing their services, and fosteringsustainable growth in cross-border digital markets.

Inicialmente, realizando um estudo de caso brasileiro do Banco Nacional de Desenvolvimento (BNDES) e,a posteriori, propondo a ampliação para outro programa denominado Minha Casa Minha Vida. No primeiro caso, apenas pessoas jurídicas estariam cadastradas no modelo, no segundo, seriam necessários nós emissores que fossem pessoas físicas: ou seja, haveria a necessidade da gestão da identidade física digital da população. O estudo proposto prevê a expansão do uso da tecnologia, bem como, o avanço nos benefícios diretos e indiretos ao incluir pessoas físicas no blockchain governamental. / [en] Use of Blockchain technology in the government sector, allowing tracking and transparency of your transactions. Initially, conducting a Brazilian case study of the National Development Bank (BNDES) and, a posteriori, proposing the extension to another program called Minha Casa Minha Vida. In the first case, only legal entities would be registered in the model, in the second, we would need issuers that were persons: that is, the need to manage the digital physical identity of the population. The proposed study predicts the expansion of technology use as well as the advancement in direct and indirect benefits by including individuals in the government blockchain.

Studying the Opportunities of Blockchain Implementations in Electronic Transactions compared to the eIDAS Regulations / Undersöka möjligheterna för blockchain implementationer i elektroniska transaktioner jämfört med eIDAS regulationenHansson, Hanna January 2022 (has links)
The electronic identification regulation, eIDAS, and its trusted service providers are currently based on technologies that have been used for decades. The eIDAS and many others in the security industry have shown interest in newer technologies such as distributed ledgers and blockchain. This research looks into the current eIDAS regulation, its plans for future work, and how the current trusted systems could benefit from introducing blockchain into the solutions. Looking at new technologies is of importance to move forward but also making solutions more secure for the user with for example Self-Sovereign Identity solutions. The research was conducted through a literature review followed by interviews. A number of themes were identified to answer the research question. The findings were that blockchain is a viable technology to use but only if used in the right cases. A better understanding and knowledge of the technology is needed for new implementation to succeed and should not be rushed due to the hype of blockchain technology. / Se bif. fil
