Khacef, Kahina. "Trade-off betweew security and scalability in blockchain systems." Electronic Thesis or Diss., Sorbonne université, 2022. http://www.theses.fr/2022SORUS516.
Full textThe development of Blockchain has enabled the emergence of high technology in the sensitive and active sectors by allowing the reliability of information via consensus, the immutability of records, and transaction transparency. This thesis presents the design, implementation, and evaluation of techniques to scale the blockchain. The first part of this thesis consists of building a decentralized, secure peer-to-peer messaging protocol using a PKI-based blockchain, which can be an email, a website, or some other form of message. Managing users’ identities by the Blockchain eliminates the single point of failure of traditional PKIs. By using smart contracts to validate, store and revoke the certificate on a public blockchain. Security and scalability are considered two significant challenges in blockchains’ rapid and smooth deployment in businesses, enterprises, and organizations. The ability to scale up a blockchain lies mainly in improving the underlying technology rather than deploying new hardware. The second contribution of the thesis proposes SecuSca, an approach that makes a trade-off between security and scalability when designing blockchain-based systems. It designs an efficient replication model, which creates dynamic sharding wherein blocks are stored in various nodes. To maintain the required level of security, the proposed approach shows that blockchain replication over the Peer_to_Peer network is minimized as the blockchain’s length evolves. Furthermore, a sharding protocol over the network is proposed to get access to the blockchain data based on historical transactions. The protocol reduces old blocks’ replication; these blocks can be discarded from specific nodes and stored by others. The nodes willing to store the coming blocks and their data are chosen randomly. The block header of each block is kept to achieve consensus. Next, we optimize the latest approach by choosing the entering nodes following the nodes’ capacities instead of randomly

Full textThe technological lock that this thesis addresses is therefore the interoperability of blockchains. Each blockchain is an independent environment with its own network, protocol and rules. They were not necessarily designed with interoperability in mind. By checking the history of transactions and identifying the author of a transaction thanks to digital signatures, it is possible to verify whether or not a transaction can be added to the chain. But to date, there is no mechanism for coordinating transactions between multiple chains to make an exchange. A system for exchanging crypto-assets between two chains seeks to satisfy the following properties; atomicity, the exchange takes place entirely or not at all, security, the participants do not risk losing their crypto-assets and finally vivacity, the duration of the exchange must be limited in time

Full textBlockchains are a disruptive technology. They enable an ecosystem for decentralized applications with interesting properties: transaction transparency, application auditability or censorship resistance. It has applications in various fields, such as finance, healthcare or video games. It has evolved a lot since its creation in 2008, and presents numerous perspectives. However, the field faces many challenges, in particular a lack of interoperability at several levels: between projects on a same Blockchain, between different Blockchains, or between Blockchains and other systems. One important aspect of Blockchain systems interoperability is semantic interoperability. It relies on formal definitions of the related concepts. Another challenge is the design of decentralized Blockchain applications. These applications integrate Blockchain technology, but also other services that satisfy the constraints of the application that Blockchain is not suitable for. However, it is complex to choose the most suited Blockchain service for a given application. With this PhD work, we propose a framework that can improve interoperability for decentralized Blockchain applications. We achieve this with the design of a methodology and a Blockchain ontology that help formalize the concepts related to an application. This framework is validated in the context of Blockchain video game development. It is a complex use case, as it needs to share storage intensive data and satisfy the latency constraints

Full textSweden is no longer in a world-leading position regarding digital administration, as it aims to be. Studies regarding digital administration show that Sweden were lowest ranked of the Scandinavian countries when it comes to usability, transparency and secure e-services. Furthermore, many Swedes think that authorities is slipping behind when it comes to digital service. The blockchain-technology is considered to have potential to be revolutionary for the digitalization of many areas. This study aims to investigate how the blockchain-technology can be used as a resource to contribute to the digital transformation of the public sector in Sweden. The goal is to research which possibilities and challenges the blockchain-technology could entail in authorities, and to identify which digital innovations it could contribute with. The data collection in the study follows a qualitative research design and has been done through six semi-structured interviews with authorities that has or intends to work with the technology and persons whose working tasks include blockchain in public sector. The collected data then generated the data that forms the basis of the study’s results. In the study we have found that blockchain could have an impact on the digital transformation of the Swedish public sector through its possibilities which has the potential to create digital innovations that could change how service, process, structure in public sector takes form in the future. The challenges identified in the study include problems with performance, lack of knowledge and experience and current legislation. Which currently prevents the blockchain’s potential to be able to create these innovations.

Full textAquesta tesi presenta un estudi de l’impacte de blockchain en las eva aplicació a les cadenes de subministrament (supply-chain o SC). Mitjançant la realització d’una recerca exploratòria la tesi presenta una anàlisi fonamentada en divuit entrevistes amb experts internacionals de diferents camps, com ara representants acadèmics, empresarials i institucionals. La recerca es divideix en quatre fases: la primera fase comença amb l’anàlisi i la identificació del tipus d’innovació per a la blockchain a SC; la segona fase analitza la combinació efectiva entre les tecnologies de blockchain i els processos de gestió de SC; la tercera fase introdueix les principals influències que afecten les operacions de SC per a una transició blockchain a SC; i el quart presenta un cas d'ús concret. Els resultats de la investigació mostren que blockchain per a SC presenta totes les característiques d’una innovació evolutiva més que disruptiva. No obstant això, els resultats van confirmar que les SC són un dels camps d’aplicació amb més projecció per a blockchain i que una SC basada en blockchain s’adapta millor als processos de gestió de relacions amb proveïdors i a les unitats de negoci financeres. Finalment, per mitigar els riscos, l’anàlisi també va identificar elements que poden donar suport als procediments de transició digital en les SC. La tesi conclou presentant els resultats trobats i proporciona suggeriments per a futures perspectives de recerca.

Full textA Tecnologia Blockchain tem o potencial de revolucionar várias indústrias e tornar os processos mais democráticos, seguros, transparentes e eficientes. Empreendedores, start-ups, investidores, as organizações internacionais e governos identificaram a Blockchain como uma oportunidade disruptiva para mudar o paradigma atual. A Blockchain é uma base de dados pública distribuída que mantém um registo permanente das transações digitais. Por outras palavras, é um arquivo de dados que armazena um registo imutável de todas as transações digitais. Esta base de dados distribuída não é controlada por uma instituição central, é por sua vez, uma rede de base de dados replicados (o que significa que cada nó na rede armazena a sua própria cópia da cadeia de blocos) que é compartilhado e visível para qualquer pessoa dentro da rede. A Inovação Disruptiva é uma abordagem que reúne todos os recursos e capacidades criativas para uma organização trabalhar na produção de ideias inovadoras e no desenvolvimento de novos negócios. O principal objetivo desta TFM será explorar os benefícios para o banco BNP Paribas ao adotar a tecnologia Blockchain nos seus processos atuais. E se estes são adequados para uma tecnologia Blockchain, com o foco na tecnologia de pagamentos para os serviços CASH e como a inovação disruptiva pode ajudar na implementação desta tecnologia no mercado onde o banco tem presença.
Blockchain Technology has the potential to disrupt multiple industries and make processes more democratic, secure, transparent, and efficient. Entrepreneurs, startup companies, investors, global organizations and governments have all identified Blockchain as a disruptive opportunity to change the current paradigm. A blockchain is a distributed public database that keeps a permanent record of digital transactions. In other words, it's a logfile storing an immutable record of all the digital transactions. This distributed database is not controlled by a central administrator, but instead is a network of replicated databases (meaning each node in the network stores its own copy of the blockchain) that is shared and visible to anyone within network. Disruptive Innovation is an approach that brings together all the creative assets, capabilities and disciplines to an organization to work together on producing breakthrough ideas and driving new business growth. The main scope of this thesis will be to explore the benefits for BNP Paribas bank in the financial landscape and if these are suitable for a Blockchain based technology, focusing on payments technology for CASH services and how disruptive innovation could help on deploying this technology in the bank.

Full textThe digitalization impact all parts of society and not least the financial sector. One technologythat is considered to have a large impact on the financial industry is blockchain technology.In this thesis, participants in the financial industry are examined with the purpose to examinetheir progress in implementing blockchain technology in their organization and how there areworking with the technology from a perspective of the Everett. M. Rogers theories ofDiffusion of Innovation. The Decision-Innovation Process and the organizations progresswith blockchain technology is particularly examined as well as concepts as communicationchannels, change agencies and opinion leaders.Representatives from SEB, Bankgirot, Skatteverket and Riksbanken have been interviewedabout their progress in implementing blockchain technology from a diffusion of innovationperspective.The result shows that all participants have some form of blockchain related project active,either in form of internal experiments or market intelligence. SEB has had the most progressin their work, probably because of their large resources. The participants mainly gatherknowledge from organizations or initiatives they consider to be opinion leaders. The opinionsleaders are for the private organizations considered to be research initiatives where theparticipating members businesses are similar to their own. For the public organizations, theopinion leaders seems to be other public organizations similar to their own. The publiccompanies have in larger extent been approached by change agencies, mainly with theintention to find a business partner for a collaboration.The progress of Bankgriot and Riksbanken are considered to be in the “persuasion stage”(stage two) while the progress of SEB and Skatteverket seems to be in the “decision stage”(stage three). None of the examined organizations progress has reached stage four or five.Future studies would include a larger number of participants from different parts of thefinancial sector. This study is proposed to be re-done in approximately five years to comparethe results.

Full textFinansiella tjänster har historiskt sätt tillhandahållits med hjälp av centraliserad datalagring genom pålitliga intermediärer såsom banker och försäkringsbolag. Detta har satt det finansiella systemet i kontroll av några få centrala aktörer vilket somliga menar har ökat den ekonomisk ojämlikheten. På senare tid, i samband med blockkedjeteknologins framväxt, har synen på demokrati och transparens skiftat. Ökad finansiell inkludering har lyfts fram som avgörande för att minska fattigdomen. Blockkedjeteknologin har framhävts att ha potential att göra skillnad i detta arbete. Denna studie fokuserar på Subsahariska Afrika där 550 miljoner individer saknar tillgång till finansiella tjänster trots att de har tillgång till mobiltelefoner. Att erbjuda mobila finansiella tjänster är viktigt för att möjliggöra finansiell inkludering. Studien ämnar därför att undersöka upplevd användbarhet av blockkedjeteknologi för mobila finansiella tjänster och hur tekniken kan utöka finansiell inkludering i kontinenten. Detta har delvis gjorts genom en forskningsresa till Sydafrika där flertalet intervjuer utfördes med personer som representerar startupbolag, regeringen, telekombranschen och den akademiska världen. Resultaten från studien visar att blockkedjeteknologin upplevs vara användbar för mobila finansiella tjänster, främst på grund av dess förmåga att sänka kostnaderna genom att ta bort mellanhänder, automatisera processer samt skapa säkra decentraliserade system. Däremot måste standardiserade protokoll och definitioner måste utvecklas innan detta kan realiseras. Fram till dess kommer det att vara svårt för blockkedjeteknolgi att göra en verklig skillnad i ökad finansiell inkludering.

Full textBackground: The Swedish Securities Market structure is complex with many intermediar- ies. Blockchain is one of the latest introduced technologies, which offers a new way of inter- action. It is a distributed ledger which builds on a chain of blocks where transactions and information is registered without the need for a third party. Financial market players are in- vestigating the potential of the technology and its applications, but as with all new innova- tions there will be challenges. Thus it is of relevance to investigate applications, challenges and potential impact of the Blockchain technology in the Swedish Securities Market. Aim: The study aims to examine potential applications, challenges and impact the Block- chain technology can have on the Swedish Securities Market and its intermediaries. Completion: To fulfill the aim of the study and attain a deeper knowledge about Blockchain a qualitative research method has been applied. Five semi structured interviews were con- ducted with market players operating on the Swedish Securities Market. Furthermore one semi structured interview has been conducted with a Blockchain expert. Conclusion: The study concludes that Blockchain has the potential to automate and streamline manually performed processes. However the full potential is restrained by pre- vailing regulations and technical limitations concerning the volume capacity. The study con- cludes that Blockchain cannot be implemented for business areas which includes large amount of volume transactions, for example clearing and settlement of shares. If only one single Blockchain is implemented the information asymmetry and the transaction costs can be reduced. However there is no solution for enabling interaction between multiple Block- chains, which can increase the degree of information asymmetry. The contribution of the study is an increased knowledge of Blockchain and its potential for the Swedish Securities Market.

Full textProfessor Henry Chesbrough gives rise to "Open Innovation" (OI) at the beginning of this millennium. He states that "Open innovation is a paradigm that starts from the assumption that companies can and should use external ideas, as well as internal and external ways of accessing the market, in order to develop their business" (Chesbrough, 2011, p. 126). The basis of OI and intellectual property rights (IPR) in different areas play a fundamental role. Bican, Guderian&Ringbeck (2017), state that there is a deactivating effect of innovation. Above all, in developing countries. Because there is a gap to promote R & D & I from the state as a promoter with universities. In addition, "Companies must organize their innovation processes to be more open to external ideas and knowledge" (Chesbrough, 2011). In Peru, and other Latin American countries, there is a need to develop policies aimed at developing open innovation. According to ECLAC (2018), the main reason for disconnection between citizens and the state is the inability of public institutions to meet the growing and changing demands of society. In addition, there are other socio-economic challenges and the need to rethink institutions to better respond to society's demands. In this paper, we will study the possible success factors of OI and DPI management, the influence of ICTs and the generation of a Hyper-collaborative ecosystem, to create value and promote greater well-being in the population.

Electronic Thesis or Diss., Université Paris Cité, 2023. http://www.theses.fr/2023UNIP7025.
Full textThis PhD thesis consists of 6 Chapters. In the first Chapter, as an introduction, we provide an overview of the general goals and motives of decentralized and permissionless networks, as well as the obstacles they face. In the introduction, we also refer to the irrational and illogical solution, known as "permissioned blockchain" that has been proposed to improve the performance of networks similar to Bitcoin. This matter has been detailed in Chapter 5. In Chapter 2, we make clear and intelligible the systems that the proposed idea, Parallel Committees, is based on such networks. We detail the indispensable features and essential challenges in replication systems. Then in Chapter 3, we discuss in detail the low performance and scalability limitations of replication systems that use consensus mechanisms to process transactions, and how these issues can be improved using the sharding technique. We describe the most important challenges in the sharding of distributed replication systems, an approach that has already been implemented in several blockchain-based replication systems and although it has shown remarkable potential to improve performance and scalability, yet current sharding techniques have several significant scalability and security issues. We explain why most current sharding protocols use a random assignment approach for allocating and distributing nodes between shards due to security reasons. We also detail how a transaction is processed in a sharded replication system, based on current sharding protocols. We describe how a shared-ledger across shards imposes additional scalability limitations and security issues on the network and explain why cross-shard or inter-shard transactions are undesirable and more costly, due to the problems they cause, including atomicity failure and state transition challenges, along with a review of proposed solutions. We also review some of the most considerable recent works that utilize sharding techniques for replication systems. This part of the work has been published as a peer-reviewed book chapter in "Building Cybersecurity Applications with Blockchain Technology and Smart Contracts" (Springer, 2023). In Chapter 4, we propose a novel sharding technique, Parallel Committees, supporting both processing and storage/state sharding, to improve the scalability and performance of distributed replication systems that use a consensus to process clients' requests. We introduce an innovative and novel approach of distributing nodes between shards, using a public key generation process that simultaneously mitigates Sybil attack and serves as a proof-of-work mechanism. Our approach effectively reduces undesirable cross-shard transactions that are more complex and costly to process than intra-shard transactions. The proposed idea has been published as peer-reviewed conference proceedings in the IEEE BCCA 2023. We then explain why we do not make use of a blockchain structure in the proposed idea, an issue that is discussed in great detail in Chapter 5. This clarification has been published in the Journal of Software (JSW), Volume 16, Number 3, May 2021. And, in the final Chapter of this thesis, Chapter 6, we summarize the important points and conclusions of this research

Full textAs receitas da indústria da música passaram por um boom quando a música digital ficou disponível. O negócio se reinventou. Mesmo com pirataria, o mercado vem crescendo desde 2015. Grande parte se deve às plataformas de streaming que introduziram um modelo de negócios (MN) de acesso, em vez de propriedade que dominava o mercado. No entanto, os principais beneficiários financeiros são as plataformas, gravadoras e editoras (os intermediários), enquanto os músicos recebem pouco de streaming. Isso se deve ao sistema de distribuição de royalties desatualizado que foi aplicado ao novo MN. Este estudo tem como objetivo propor um MN atualizado, através da inovação do sistema de pagamento com o uso de tecnologia blockchain (TB). Esta criaria um sistema contábil justo e transparente, além de melhorar a confiança dos profissionais no sistema. Dados secundários sobre inovação estratégica, indústria da música e inovação em MN foram analisados . Os dados primários qualitativos e quantitativos foram coletados por meio de pesquisa e entrevistas semiestruturadas realizadas com profissionais do setor. Os resultados revelam que a TB pode mudar o jogo em relação a contabilização e pagamento de royalties. No entanto, há pouco conhecimento sobre o uso, portanto não há imediatismo por parte da indústria para implementa-la. Além disso, a indústria carece de incentivos para mudar o MN, já que grandes players conduzem o show, deixando músicos sem alternativas para promover mudanças. Por fim, o estudo conclui que, embora seja uma possível solução para o problema, o setor ainda não aceita esse tipo de mudança.

Klaus Schwab, founder of the World Economic Forum (WEF), once said that the blockchain is the fourth industrial revolution since the invention of steam, electricity and computers. The game industry has boomed in the blockchain, and according to Dutch market research firm Newzoo, the gaming industry is expected to grow to $128 billion by 2020. It can be seen that the market value of the game market continues to grow and there are amazing trading volumes. Through the blockchain, its impossible to modify, anonymity, openness and decentralization characteristics can solve the pain points of the game industry which is too centralized and digital assets are difficult to manage. This thesis will use the game cases - CryptoKitties, FOMO 3D, and Gods Unchained as the research target. Besides, we will explore these three famous blockchain game by using Case Analysis Method to find whether the elements of innovation are in line with the blockchain core or not and summarize the innovation factors of blockchain games. And whether this disruptive innovation using in the game industry can bring new value to the stakeholders. It is worthy of being a reference for the development of relevant industry in the future.

Full textBlockchain technology is a foundational technology with various use cases that can significantly impact the manner in which banking is carried out in South Africa. The following paper seeks to put together a framework for understanding the potential effect of blockchain technology on the South African banking environment, with a specific focus on how blockchain technology will impact the South African banking environment (i.e. the applications and use cases) and when this impact will take place. A qualitative approach to addressing the problem statement was adopted, specifically in the form of focus interviews and strategic discussions with subject matter experts in both the blockchain and South African banking environment. Findings indicate that there are number of blockchain applications that can impact the South African banking environment namely, Private Digital Ledgers, Smart Contracts and Tokens/ Cryptocurrencies. Further to this, research indicates that the former is most likely in the short term, while the latter two applications are subject to a high-level stakeholder coordination, a high level of effort in educating the end customer and a high level of friction from existing systems and process, and will therefore only realise mass adoption in the long-term. As a result, this research contributes to providing an initial view of which applications are most likely to be adopted by South African banks and can form the foundation for further research in this area.

The emergence of blockchain technology is in response to the 2008 financial turmoil, and it is expected to replace the artificially regulated financial model with decentralized technology. As for the innovation of this technology in Taiwan, it presents an innovative model for improving financial service processes and establishing alternative financial ecosystems. Therefore, this paper combines regional diversity theory and geographic elements to generate an analytical framework, and explores the innovation activities of regional industries with Taiwan's application of blockchain technology in the financial technology industry. This paper adopts the qualitative research methodology. The data collection methods include second-hand data collection, field observation, and in-depth interviews. The interpretive analysis is used to analyze and interpret the data. The conclusions of this paper are three: First, the innovation of financial technology industry based on blockchain presents two ecological modes: innovation within the system and innovation outside the system. Second, the blockchain-based financial technology industry innovation is influenced by the external environment at the global, national and regional scales, covering the regulatory orientation and industrial environment. Third, key actors practice the technology learning and exchange, niche market expansion, and industry normative discussions required for financial technology industry innovation through spatial strategies such as temporary clustering and project organization.

Full textO branqueamento de capitais e financiamento do terrorismo são atos criminosos graves que contribuem para a economia paralela e prejudicam o bem-estar da sociedade. A evolução constante do ramo tecnológico, faz com que os crimes de BC/FT se tornem cada vez mais complexos e dinâmicos, dificultando os esforços conduzidos pelos reguladores e autoridades competentes. As instituições financeiras, veículos atrativos para este tipo de crimes, também desempenham um papel fundamental no combate ao BC/FT. Assim, estas devem dispor de controlos adequados, de forma a assegurar o cumprimento com os requisitos legais. A tecnologia blockchain surgiu no contexto das criptomoedas. No entanto, as propriedades e flexibilidade de que dispõe, permitem que esta seja utilizada nas mais diversas áreas, incluindo na indústria dos serviços financeiros. O objetivo desta dissertação passa por avaliar o impacto da adoção de soluções tecnológicas baseadas na blockchain por parte das instituições financeiras no cumprimento dos requisitos legais em termos de PBC/FT, especialmente em cenários que afetem diretamente o referido processo. Devido à escassez de dados quantitativos relevantes, as conclusões foram geradas com base em revisão literária sobre ambos os tópicos, juntamente com conhecimentos práticos. Os resultados mostram que o impacto da adoção de soluções tecnológicas baseadas na blockchain por parte das instituições financeiras na gestão do PBC/FT é positivo no contexto de redes privadas ou híbridas. Por outro lado, as redes públicas não cumprem com os requisitos legais de PBC/FT. Não obstante, é necessária a produção de legislação específica e cada caso particular deverá ser analisado individualmente.

Full textA sustentabilidade é um dos maiores desafios sociais do nosso tempo, por isso a Organização das Nações Unidas implementou 17 objectivos de desenvolvimento sustentável. Soluções estão a ser exploradas no domínio da digitalização. A indústria 4.0, incluindo a inteligência artificial, a internet das coisas, os robôs e a cadeia de bloqueio podem mudar o progresso social e económico. O desenvolvimento no sentido de um novo tipo de consciência e desafios sustentáveis na indústria alimentar força empresas a criarem e implementarem ações sustentáveis. As empresas são confrontadas com novas exigências na sua cadeia de abastecimento alimentar, para não perderem a sua posição no mercado. Para atingir uma solução exequível, foi analisada a ligação entre a tecnologia Blockchain e a sustentabilidade da cadeia de abastecimento alimentar das PMEs. O enorme potencial desta solução é contrariado por riscos que ainda não explorados, especialmente para as PMEs alemãs. A tecnologia Blockchain como DL (distributed ledger) pode trazer uma vantagem significativa para a cadeia de abastecimento alimentar, devido à sua capacidade de rastreio e rastreabilidade, no entanto ainda se encontra numa fase inicial do seu desenvolvimento. A sua influência e importância na indústria alimentar está a aumentar e consequentemente na gestão da cadeia de abastecimento das empresas. O objectivo desta tese é determinar a importância da gestão sustentável da cadeia de abastecimento das PME's do sector alimentar que contam com a ajuda da tecnologia da cadeia de bloqueio, ao mesmo tempo que é avaliado o seu potencial e riscos no mercado alimentar alemão.

Full textAs empresas fintech surgiram tomando partido dos atuais desenvolvimentos tecnológicos tendo desafiado os atuais atores do mercado. Projetos disruptivos financiados nomeadamente por cripto moedas são um dos tópicos relacionados com o desenvolvimento tecnológico e capazes de eliminar a necessidade para o envolvimento de terceiros na mediação financeira reduzindo assim o hiato entre investidores e promotores. O propósito desta tese é o de identificar os principais impactos que as empresas fintech têm nos modelos de negócio das empresas financeiras já estabelecidos no mercado. Terá um foco especial nos fatores de sucesso dos projetos baseados na blockchain denominados Initial Coin Offerings (ICOs), em particular, os fatores relacionados com o capital humano. Assim, a tese está dividida em três estudos principais com focos diferentes. A metodologia usada nesta tese é de métodos mistos: uma metodologia qualitativa foi usada na revisão sistemática da literatura; e uma metodologia quantitativa foi usada na construção e estimação de modelos econométricos, tendo por base microdados de 428 projetos de ICOs do setor bancário. Esta tese conclui que as fintechs não podem ser ainda consideradas substitutos dos serviços financeiros tradicionais. Contudo, estas colocam desafios e expõem as fraquezas dos modelos de negócio tradicionais. A indústria financeira necessita de adaptar urgentemente os seus modelos de negócio para se manter competitiva. Este desafio já foi aceite por várias empresas. Os ICOs causam disrupção e são um grande passo para a democratização dos investimentos financeiros. Este estudo identificou um conjunto alargado de fatores de sucesso que influenciam o resultado final destes projetos. Os fatores podem agrupar-se em categorias: (i) projeto; (ii) campanha; (iii) redes sociais; (iv) capital humano. Os fatores que esta tese comprovou contribuírem para o sucesso de um projeto são os seguintes: pré-existência de limites de financiamento; a qualidade do whitepaper; a existência de um mercado secundário e esquema de bonificações; o preço dos tokens; o preço das cripto moedas; a boa gestão de redes sociais; a localização geográfica e a rede de contactos dos promotores; o tamanho das equipas; ratings externos atribuídos ao projeto e à equipa.No que diz respeito às contribuições teóricas, esta tese contribuiu para a escassa literatura no tema dos ICOs e para duas teorias, nomeadamente a siganling theory e Human Capital Theory (HCT). As contribuições práticas deste estudo relacionam-se com a avaliação da qualidade do projeto e a necessidade premente dos reguladores tomarem medidas nestes mercados.

Full textA Oferta Inicial de Moedas(ICO) é um tema moderno e tem estado em voga desde a sua criação. Comummente denominadas como Token Sales, as OIC são assistidas por tecnologia de blockchain e surgiram com o objetivo de apoiar os empresários no financiamento dos seus empreendimentos, que ainda se encontram na fase inicial, numa escala descentralizada e global. Tem vindo a reunir cada vez mais pessoas e dinheiro ao longo dos anos, levando muitos estudos a serem desenvolvidos no seu contexto, a fim de compreender esta mudança nos mercados de capitais públicos. Apesar deste facto, os OIC são ainda um tópico fértil onde ainda mais ramos de investigação podem nascer para serem analisados. Os ratings das OIC já provaram ter impacto no sucesso dos projetos, desta forma, este estudo visa fornecer provas com o apoio de uma base de dados mais robusta, com 5581 OIC. Com base nos ratings disponíveis no site ICObench, foram realizados testes de hipóteses, apoiados em gráficos de boxplot, a fim de medir e compreender a associação entre as variáveis. Este documento confirma as conclusões de literatura anterior, mostrando que os ratings estão de facto associados ao sucesso dos projetos. Conclui, deste modo, que ratings maiores têm uma influência positiva na angariação de fundos das OIC. Outras variáveis como a plataforma onde operam, o número de moedas aceites como pagamento, o número de membros da equipa, se foi estabelecido hard-cap e soft-cap e outras, foram incluídas no presente estudo. Além disso, a base de dados foi dividida pelos diferentes setores e desenvolvida uma visão geral sobre a distribuição das classificações e do desempenho dos projetos, para cada um. Estes dados podem contribuir com alguns insights e ajudar investigações futuras a dar o próximo passo na realização de análises individuais e detalhadas para cada sector.

Full textA cerveja artesanal tem revolucionado a indústria e o mercado mundial da cerveja, através da sua diversificação, inovação, autenticidade e tradição. Estas PMEs vieram desafiar as grandes cervejarias que operam num mercado altamente homogeneizado e consolidado. Assim, enfrentar os desafios da sustentabilidade no sector da cerveja artesanal é urgente. Este estudo tem dois objetivos. O primeiro é compreender como é possível melhorar a sustentabilidade numa PME portuguesa fabricante de cerveja artesanal chamada BARONA Brewing Company e implementar práticas de sustentabilidade no modelo de negócio. O segundo objetivo é orientado para o nível operacional, procurando compreender como é possível esta microcervejeira adaptar-se a uma cadeia de abastecimento transparente. Para fornecer sugestões com valor, foi escolhida uma metodologia mista. Serão recolhidas informações sobre as atividades de sustentabilidade e da cadeia de abastecimento, através da observação direta no terreno e de entrevistas semiestruturadas. Os resultados evidenciam que a sustentabilidade não é um foco para as cervejeiras artesanais. É um desafio melhorar os processos e as medidas de sustentabilidade, mas é possível incluí-la no modelo de negócio através da redução do consumo de recursos, minimização do desperdício e foco na produção eficiente. Assim será rentável e a empresa ficará mais próxima de uma abordagem totalmente sustentável. Quando se trata do tema de transparência da cadeia de abastecimento e da utilização de tecnologia de blockchain, isto é ainda mais desafiante uma vez que necessita de investimento de tempo e dinheiro, algo que algumas cervejeiras artesanais podem não ser capazes de disponibilizar.
