This bachelor thesis focuses on how insiders of the Solana ecosystem understand the success of decentralized finance (DeFi) projects and what factors they consider key to achieving it. The aim of the thesis is to identify and structure the main product, team, community, user, economic, and ecosystem dimensions that, according to respondents, collectively shape the success of DeFi projects on the Solana platform. The research is based on a literature review of DeFi and the specifics of the Solana ecosystem, as well as a qualitative survey based on eight semi-structured interviews with members of DeFi project teams and micro-influencers active in Solana DeFi. The data was analyzed using thematic analysis, which led to the identification of eleven main themes covering, among other things, product value and innovation, the role of the team and network, community and communication, UX/UI and onboarding, tokenomics and value distribution, security, integration and partnerships, and the influence of market cycles and narratives. The results show that success is not associated with a single isolated factor, but with a portfolio of interdependent dimensions, some of which are directly controlled by project creators and some of which are determined by the broader ecosystem and market context. The work provides a theoretical contribution in the form of a systematic framework of success factors for DeFi projects specifically in the Solana environment, as well as a practical contribution for creators, investors, and other actors, offering them a roadmap for designing, evaluating, and strategically managing DeFi projects on this platform.

The rapid evolution of 5G and the growing complexity of digital services have increased the need for robust, transparent, and automated Service Level Agreement (SLA) management. Traditional management methods across different sectors like telecommunications and cloud computing frequently suffer from a lack of transparency and a heavy reliance on centralized third parties, which can lead to disputes and delayed enforcement. To address these challenges, smart contracts using blockchain technology offer a transformative solution, automating SLA execution and ensuring decentralized, tamper-proof enforcement. This paper provides a comprehensive survey and critical analysis of existing traditional SLA management systems and smart contract-based management. By studying and examining various frameworks across 5G, cloud computing, IoT, and telecommunications, we highlight common strategies, technical trade-offs, and existing gaps in current research. Through a structured classification and comparative analysis, this study offers an overview of blockchain-based SLA management current state while providing a strategic roadmap for the future of SLA representation and automated lifecycle management.

Flash loans enable uncollateralized borrowing within a single transaction, providing capital efficiency and arbitrage opportunities in decentralized finance (DeFi). However, when combined with composable protocols and reactive state changes, flash loans can induce feedback loops that amplify liquidity, manipulate pricing signals, and bypass economic safeguards. This paper defines Flash Loan Feedback Loops as recursive transaction patterns in which temporary liquidity repeatedly influences protocol state, enabling extraction of value without proportional risk exposure. We analyze structural conditions that permit such loops, demonstrate why existing mitigations are insufficient, and propose a logic-layer enforcement framework that constrains state-dependent recursion. The approach restores causal integrity between capital commitment and protocol outcomes, addressing a core systemic vulnerability in DeFi architectures.

Die vorliegende Arbeit befasst sich mit dem Spannungsfeld zwischen staatlicher Kontrolle und indi-vidueller Autonomie bei der Gestaltung von digitalen Zentralbankwährungen (Central Bank DigitalCurrencies, CBDCs). Auf Basis einer vergleichenden Analyse vier bestehender Systeme – Sand Dollar(Bahamas), e-CNY (China), eNaira (Nigeria) und e-Krona (Schweden) – wird eine deutliche Tendenzzur Zentralisierung sowie ein weitgehendes Fehlen von Technologien zum Schutz der Privatsphäre(Privacy-Enhancing Technologies) aufgezeigt. Mithilfe eines normativen Bewertungsrahmens, der diesechs Kriterien Dezentralisierung, Datenschutz, Interoperabilität, finanzielle Inklusion, Finanzstabil-ität und regulatorische Compliance umfasst, wird ein bislang unbesetztes Gestaltungsfeld identifiziert.Um diese Lücke zu schließen, wird ein Referenzmodell konzipiert, das eine erlaubnispflichtige(permissioned) Distributed Ledger Technology mit Zero-Knowledge Proofs, selektiver Offenlegungund einer Multi-Stakeholder-Governance verknüpft. Die technische Machbarkeit dieses Modells wirddurch einen funktionalen Python-Prototyp belegt. Die Ergebnisse stützen die Hypothese, dass hybrideArchitekturen Dezentralisierung, Privatsphäre und regulatorische Konformität erfolgreich in Einklangbringen können.

ii ABSTRACT Survival in the Stigmatized Industry (Bitcoin ATM) Brooks McAdam This paper examines how companies can survive in a stigmatized industry where the same message may attract customers while simultaneously generating skepticism. The study posed the following research question using the Bitcoin ATM industry as the context: Does the message presented on company websites influence the degree of exit risk in a market characterized by moral concerns, exposure to fraud, and unstable regulation? The answer is clear. Messaging is important; however, not every message is equally important. Fee-related messaging emerged as the most consistent predictor of exit risk. Messaging emphasizing ease of use showed a recurring but less consistent association with elevated exit risk, while security messaging demonstrated only limited evidence of a protective effect among the 71 operators analyzed. The message about freedom or privacy did not have a significant impact. These findings change the agenda of the survival research not only to the broad characteristics of firms but also to the assertions that firms wish to make publicly.

Private Smart Contracts (PSCs) aim to settle the privacy protection issue for sensitive data on the blockchain (a.k.a., on-chain data) while inheriting the computation functionality of general smart contracts. However, most of the existing PSCs focus on secure computation and ignore the secure and flexible management of on-chain data, making it difficult to support flexible user permission modes efficiently. Further, although a few on-chain data management schemes have been proposed to manage data on the blockchain, they provide insufficient support for scenarios where data must be managed concurrently by managers with different privilege levels. This paper proposesMISC, a novel solution that features efficient and flexible data management capabilities for managing on-chain data in private smart contracts.MISCleverages a novel Double Trapdoor Homomorphic Proxy Re-encryption (DT-HPRE) scheme and Trusted Execution Environments (TEEs) to ensure (1) low-overhead, flexible permission control over on-chain data and (2) a harmonious mechanism for both privileged and constrained managers. We prove the security ofMISCunder the Universal Composability (UC) framework to demonstrate its data confidentiality guarantees, user revocation, and computation integrity. Further, we implementMISC, and the performance evaluation shows that on-chain data access for one hundred data points is practically achieved in 5.8 s (under privileged managers) and 9.7 s (under constrained managers) using its off-chain design.

Non-Fungible Tokens (NFTs) have emerged as a new organizational layer of digital exchange, raising questions about how participation, concentration, and community formation are structured within on-chain markets. Understanding whether these structures differ systematically across blockchain ecosystems with distinct asset orientations requires examining ecosystem-level interaction patterns. Most studies focus on specific collections or single platforms, offering limited insight into how connectivity, concentration, and community structure vary across markets with different NFT use cases. This study compares Ethereum and Polygon, two major NFT platforms with distinct dominant asset orientations (investment-oriented vs utility-oriented), to examine how their transaction networks differ at the ecosystem level. Using 3.9 million NFT transactions from May 2022 to May 2024, we apply network analysis to assess connectivity, centralization, community structure, and temporal dynamics. The findings show highly skewed interaction patterns in both ecosystems, with a small subset of addresses accounting for a disproportionate share of activity. Polygon networks exhibit higher modular segmentation and sharper upper-tail dominance, with communities aligning near-perfectly with application-specific boundaries, whereas Ethereum networks display comparatively more integrated, crosscollection interaction structure. These contrasts are interpreted as ecosystem-level structural patterns conditional on each chain's market composition and dominant NFT use cases, offering socio-technical insights into how participation concentrates and communities form across blockchain-based digital markets.
