Cryptocurrencies have transformed financial markets with their innovative blockchain technology and volatile price movements, presenting both challenges and opportunities for predictive analytics. Ethereum, being one of the leading cryptocurrencies, has experienced significant market fluctuations, making its price prediction an attractive yet complex problem. This paper presents a comprehensive study on the effectiveness of Large Language Models (LLMs) in predicting Ethereum prices for short-term and few-shot forecasting scenarios. The main challenge in training models for time series analysis is the lack of data. We address this by leveraging a novel approach that adapts existing pre-trained LLMs on natural language or images from billions of tokens to the unique characteristics of Ethereum price time series data. Through thorough experimentation and comparison with traditional and contemporary models, our results demonstrate that selectively freezing certain layers of pre-trained LLMs achieves state-of-the-art performance in this domain. This approach consistently surpasses benchmarks across multiple metrics, including Mean Squared Error (MSE), Mean Absolute Error (MAE), and Root Mean Squared Error (RMSE), demonstrating its effectiveness and robustness. Our research not only contributes to the existing body of knowledge on LLMs but also provides practical insights in the cryptocurrency prediction domain. The adaptability of pre-trained LLMs to handle the nature of Ethereum prices suggests a promising direction for future research, potentially including the integration of sentiment analysis to further refine forecasting accuracy.
The U.S. dollar's status as the global reserve currency faces growing challenges from a 36 trillion dollar national debt, geopolitical shifts, and the emergence of digital currencies. This paper introduces the Quantum Reserve Token (QRT), a decentralized digital currency backed by quantum computational capacity - a scarce, productive resource projected to add over 1 trillion dollars to global GDP by 2035. Unlike Bitcoin's fixed-supply volatility, stablecoins' dependence on fiat trust, or central bank digital currencies' jurisdictional limits, QRT uses quantum computing power as a novel value anchor. This study develops a monetary theory-based framework for QRT, compares it to existing digital currency models, and evaluates its feasibility across technological, economic, geopolitical, and adoption dimensions. QRT offers a stable, neutral, and scalable reserve currency alternative, potentially reshaping the global monetary system.

The modern global financial environment faces a complex combination of requirements associated with ensuring systemic solvency while preventing the use of banks as conduits for illegal financial transactions. The current paper focuses on evaluating the capacity of modern regulatory standards for addressing these interconnected challenges. While modern legislation and regulatory approaches have reached a new level of sophistication and standardization, the dynamic nature of innovations in the field of decentralized finance integrate specific examples of Explainable AI (XAI) tools like SHAP values or Grad-CAM that regulators are currently using to improve transparency in decentralized finance. A qualitative-comparative methodology is employed for exploring the impact of strict enforcement of financial standards on the sustainability of the banking sector. Using case studies drawn from some of the world's largest economies, such as the EU, the US, and India, the study finds that despite the positive impact of regulations on the core of the global economy (e.g., through enhancing the financial cushioning of banks), there is evidence that the displacement effect has occurred, which means that risks and illegal activities continue to be relocated to the shadow economy. From the policy implications, a shift from a response-oriented and rule-based approach to one that is proactive and intelligence-based, emphasizing globalization and integration, becomes evident. For future regulation, there is a need for the coverage to be extended to non-bank financial institutions as well as dealing with the paradox of compliance whereby escalating costs have not yet translated into less global money laundering.
In response to the issues of high transaction transparency and regulatory difficulties in blockchain account-model transactions, this paper presents a supervised blockchain anonymous transaction model based on certificateless signcryption aimed at ensuring secure blockchain transactions while minimizing both computational and communication overhead. During the transaction process, this approach utilizes certificateless public key signcryption without bilinear pairs to generate anonymous user identities, achieving strong anonymity of user identities and confidentiality of transaction amounts. It employs the Paillier homomorphic encryption algorithm to update transaction amounts and uses the FO commitment-based zero-knowledge proof scheme to validate transaction legality. Additionally, adopting a publicly verifiable secret threshold sharing scheme for hierarchical regulatory authority reduces the security risk of a single regulator storing the regulatory key. This model not only meets the privacy and timely update requirements of account-based blockchain transactions but also effectively regulates abnormal transactions. Rigorous security analysis and proofs demonstrate that this model possesses excellent anonymity, traceability, forward security, and backward security. When compared to similar schemes, the computational cost is reduced by at least 33.18%, effectively fulfilling the requirements for security.
Medical big data holds significant value in promoting precision medicine, disease prediction, and public health management. However, issues such as sensitivity, decentralization, and privacy security limit its in-depth application. This study proposes a collaborative computing framework based on blockchain and Apache Spark, aiming to address the challenges of privacy protection, cross-institutional sharing, and efficient analysis of medical data. By designing an access control mechanism based on smart contracts and an anonymization scheme utilizing zero-knowledge proofs, combined with Spark's distributed memory computing advantages, a secure and trustworthy platform for medical data analysis is constructed. Experiments demonstrate that this framework improves data processing efficiency by 3.5 times compared to the traditional Hadoop architecture on the MIMIC-III dataset, while also meeting HIPAA privacy standards. This study provides theoretical support and practical pathways for the application of "blockchain + big data" technology in the medical field.
Os chamados smart contracts ou “contratos inteligentes” são uma inovação tecnológica difundida a partir do lançamento da plataforma Bitcoin em 2009 e, principalmente, da plataforma Ethereum em 2014. Em princípio, eles têm como propósito automatizar a execução das obrigações das partes em um negócio jurídico, de modo a diminuir o risco de seu inadimplemento e evitar a dependência de um terceiro de confiança (seja ele um árbitro, um juiz ou mero registrador dos dados referentes à transação celebrada). O potencial uso de smart contracts em vários setores econômicos desperta questionamentos sobre a adequação das normas do direito contratual tradicional para sua regulação. No presente trabalho, busca-se analisar dois pontos específicos sobre o tema, a saber: o momento de formação do negócio jurídico segundo a disciplina trazida pelo Código Civil brasileiro e as consequências de um contrato inteligente com objeto ilegal. O trabalho revisa amostra da literatura dedicada ao tema, tanto nacional quanto estrangeira, esta última sobretudo quando provinda de autores dos Estados Unidos da América e de Estados membros da União Europeia. O texto também questiona a adequação dos novos negócios ao marco normativo brasileiro sobre negócios.

The objective of this paper is to analyze non-fungible token (NFT) games under Copyright Law No. 28 of 2014 and explore measures to prevent third-party copyright infringements. The research follows a normative legal methodology, utilizing both a conceptual and statutory approach. Legal materials are gathered through document studies. The analysis conducted is qualitative in nature. This study concludes that NFT games are protected by copyright as they qualify as intellectual property under Indonesian law. Copyright protection is granted automatically upon the creation of the game, meaning no formal registration is required for copyright to take effect. However, to ensure stronger legal certainty, business entities and copyright holders are encouraged to register their NFT games. This registration provides an official record and reinforces the protection of their intellectual property rights. In addition, the paper discusses preventive measures that copyright holders can take to safeguard their rights. For instance, they can monitor for unauthorized use of their NFT games in commercial activities. If individuals or organizations exploit the copyrighted material without permission, the copyright holders can report the infringement to the relevant ministry. This approach ensures that copyright holders can enforce their rights and protect their creations from misuse. In summary, the study emphasizes the importance of copyright registration and vigilance in preventing infringement, while highlighting the automatic protection NFT games enjoy under Indonesian law.
The rapid growth of Fintech has driven the adoption of blockchain technology for secure, efficient, and tamper-proof digital transactions. However, existing blockchain systems face challenges such as doublespending attacks, inefficient consensus mechanisms, and limited trust management, which hinder their scalability and security. To overcome these issues, this research proposes the Fin Trust Blockchain Framework (FTBF), a multi-layered architecture designed to provide secure, scalable, and transparent solutions for Fintech applications. FTBF integrates Zero Trust Architecture (ZTA) at its core to ensure continuous user, node, and transaction validation. To prevent double-spending attacks, the Dynamic Coin Flow Output Model (DCFOM) tracks unspent transaction outputs, ensuring the uniqueness of digital tokens. The framework also introduces a novel consensus mechanism, the Time Elapsed Stake Secure Algorithm (TESSA), which enhances scalability and energy efficiency. Additionally, the Fair Trust Rating Server (FTRS) dynamically calculates and updates trust scores for network participants, storing them on a trust score ledger for transparency and accountability. FTBF addresses key blockchainsecurity, efficiency, and trust management limitations, paving the way for next-generation Fintech solutions with enhanced scalability, resilience, and transparency.
The rapid adoption of artificial intelligence (AI) systems, such as predictive AI, generative AI, and explainable AI, is in contrast to the slower development and uptake of robotic AI systems. Dynamic environments, sensory processing, mechanical movements, power management, and safety are inherent complexities of robotic intelligence capabilities that can be addressed using novel AI approaches. The current AI landscape is dominated by machine learning techniques, specifically deep learning algorithms, that have been effective in addressing some of these challenges. However, these algorithms are subject to computationally complex processing and operational needs such as high data dependency. In this paper, we propose a computation-efficient and data-efficient framework for robotic motion intelligence (RMI) based on vector symbolic architectures (VSAs) and blockchain-based smart contracts. The capabilities of VSAs are leveraged for computationally efficient learning and noise suppression during perception, motion, movement, and decision-making tasks. As a distributed ledger technology, smart contracts address data dependency through a decentralized, distributed, and secure transactions ledger that satisfies contractual conditions. An empirical evaluation of the framework confirms its value and contribution towards addressing the practical challenges of robotic motion intelligence by significantly reducing the learnable parameters by 10 times while preserving sufficient accuracy compared to existing deep learning solutions.
Cryptocurrency is a novel exploration of a form of currency that proposes a decentralized electronic payment scheme based on blockchain technology and cryptographic theory. While cryptocurrency has the security characteristics of being distributed and tamper-proof, increasing market demand has led to a rise in malicious transactions and attacks, thereby exposing cryptocurrency to vulnerabilities, privacy issues, and security threats. Particularly concerning are the emerging types of attacks and threats, which have made securing cryptocurrency increasingly urgent. Therefore, this paper classifies existing cryptocurrency security threats and attacks into five fundamental categories based on the blockchain infrastructure and analyzes in detail the vulnerability principles exploited by each type of threat and attack. Additionally, the paper examines the attackers' logic and methods and successfully reproduces the vulnerabilities. Furthermore, the author summarizes the existing detection and defense solutions and evaluates them, all of which provide important references for ensuring the security of cryptocurrency. Finally, the paper discusses the future development trends of cryptocurrency, as well as the public challenges it may face.

This paper examines how on-chain factors (number of active wallets, transaction fees, and transaction volume) and off-chain factors (liquidity and investor attention) impact Bitcoin market efficiency from April 2014 to April 2022. We identify three periods in Bitcoin’s market development: development, growth, and additional development stage. We propose three hypotheses: (1) increased investor attention enhances market efficiency, (2) a rise in active users improves efficiency directly and through liquidity and investor attention, and (3) higher transaction fees and on-chain volume positively impact efficiency directly and indirectly. Our findings support these hypotheses during Bitcoin’s development and growth periods. However, in the additional development stage, the total effect of active users, transaction fees, and transaction volume becomes negative when considering mediating effects, and largely insignificant when focusing on direct effects. Additionally, we find increased netflow between whales and exchanges, a proxy for institutional activity, improves efficiency. We conclude that as Bitcoin’s market develops, factors such as changing user composition and increased regulatory scrutiny alter the dynamics of on-chain factors and their influence on market efficiency.
Blockchain technology affords the secure and effective means for addressing the spiking cases of financial frauds and inefficiencies. Using the immutable and distributed nature, blockchain provides robust transaction security. However, NFTs have significant limitations in the financial use scenario due to the non-fungible characteristics that discourage the consistent valuation and exchangeability. To overcome these challenges, the proposed system integrates NFTs into banking operations and enhances their utility in secure financial transactions. The system uses the Proof of Stake algorithm to record transactions on the blockchain, offering energy efficiency and scalability compared to traditional Proof of Work. This method ensures secure and reliable transaction processes while addressing the high demands of financial systems. The framework thereby extends the utility of NFTs beyond digital collectibles, redefining the concept of asset management in banking and creating innovative opportunities for financial applications. The results show that the incorporation of NFTs into blockchain technology improves transaction security and efficiency, thus establishing the potential for financial innovation. This approach not only minimizes risks associated with traditional systems but also introduces a transformational model for managing digital assets in banking. By utilizing NFTs in secure blockchain frameworks, the system opens avenues for scalable and innovative financial practices.

This work analytically characterizes impermanent loss for automated market makers (AMMs) in decentralized markets such as Uniswap or Balancer (CPMM). We derive a static replication formula for the pool's value using a combination of European calls and puts. Furthermore, we establish a result guaranteeing hedging coverage for all final prices within a predefined interval. These theoretical results motivate a numerical example where we illustrate the strangle strategy using real cryptocurrency options data from Deribit, one of the most liquid markets available.
Can we create binding agreements between nations? Recently, scholars have argued that blockchain technology enables us to do so. Given that this could greatly affect the anarchical world order implied by state sovereignty, this remarkable claim is investigated thoroughly. By focusing on the technical implementation of smart contracts between nations, this article finds that the potential to create binding agreements using blockchain technology is far more limited than recently suggested.

With the rapid development of blockchain technology, consensus algorithms have become a significant research focus. Practical Byzantine Fault Tolerance (PBFT), as a widely used consensus mechanism in consortium blockchains, has undergone numerous enhancements in recent years. However, existing review studies primarily emphasize broad comparisons of different consensus algorithms and lack an in-depth exploration of PBFT optimization strategies. The lack of such a review makes it challenging for researchers and practitioners to identify the most effective optimizations for specific application scenarios. In this paper, we review the improvement schemes of PBFT from three key directions: communication complexity optimization, dynamic node management, and incentive mechanism integration. Specifically, we explore hierarchical networking, adaptive node selection, multi-leader view switching, and a hybrid consensus model incorporating staking and penalty mechanisms. Finally, this paper presents a comparative analysis of these optimization strategies, evaluates their applicability across various scenarios, and offers insights into future research directions for consensus algorithm design.
