Cryptocurrency has become one of the most intriguing topics in finance and technology in recent years. With the growing prominence of Bitcoin, the rise of altcoins (alternative cryptocurrencies) also demonstrates significant potential within the cryptocurrency market. Altcoins, which include all cryptocurrencies other than Bitcoin, offer diverse functionalities and use cases, ranging from smart contracts to decentralized finance (DeFi) applications. This thesis identifies the altcoin options with the best investment opportunities and the highest growth potential. The study employs the Preference Selection Index (PSI) method, a multi-criteria decision-making approach that evaluates alternatives based on specific preferences and criteria. This method is particularly suitable for assessing complex investment decisions involving multiple variables, such as market capitalization, technological innovation, and utility. By applying PSI, investors can decide which altcoins will likely yield substantial returns. A web-based platform has been developed as part of this research to simplify selecting promising altcoins. This platform enables users to evaluate options based on predefined criteria, such as market trends, project objectives, and development team credibility. The accessibility of this tool empowers users—whether novice or experienced investors—to navigate the dynamic cryptocurrency market more effectively. Altcoins provide a unique opportunity for diversification in investment portfolios. Unlike Bitcoin, which is often viewed as a store of value, many altcoins are designed with specific purposes and innovative features. For instance, Ethereum introduced smart contracts that revolutionized decentralized applications, while other altcoins focus on scalability or niche markets like the Internet of Things (IoT). However, investing in altcoins also comes with challenges like high market volatility, security risks, and regulatory uncertainties. Therefore, thorough research and strategic planning are essential for minimizing risks while maximizing returns in this rapidly evolving sector.

Continuous expansion of Blockchain Technology (BCT) has resulted in significant advancements across different domains, such as finance, healthcare and supply chain management. With Bitcoin as an example, blockchain technology has completely changed the nature of digital currencies and decentralized financial systems. Scalability and transaction throughput of BC networks is one of their main concerns. This problem has been continuously addressed by Bitcoin, whose decentralized architecture frequently leads to delayed transaction processing times. To improve the Students Digital Fee Payment System (SDFPS) in higher education, we suggest a technique that uses weak blocks in the subchain to speed up transaction processing and boost Bitcoin transaction rates. We offer a comprehensive evaluation of Bitcoin’s performance in relation to the subchain concept, a novel approach to boosting scalability without sacrificing security. Main goal of this research is to apply layered subchain technique to improve speed and efficiency of Bitcoin transactions. Technology behind Bitcoin highlights how important scalability is for SDFPS in blockchain networks. Subchains are introduced, and their potential for accelerating transaction processing is discussed. An in-depth description of the subchain implementation’s architecture and design is made, highlighting the main elements and how they work together. Subchain solution’s development process includes the creation of weak blocks, validation of strong blocks, and the integration with the main blockchain is implemented.
Verifying certificates is essential for ensuring the authenticity and integrity of academic credentials. Traditional systems are prone to vulnerabilities, including data misuse and forgery, necessitating the adoption of more secure digital solutions. This project leverages blockchain technology on the Ethereum platform, chosen for its secure smart contracts and widespread adoption, and the InterPlanetary File System (IPFS) to provide a decentralized and tamper-proof framework for certificate validation. Blockchain-based hashing techniques are employed to confirm the legitimacy of certificates, while IPFS enables secure off-chain storage of large certificate files. This hybrid approach reduces storage requirements by storing only certificate hashes on-chain while using IPFS for storing large files, ensuring efficiency. The system stores certificate data on IPFS, generating a unique hash recorded on the Ethereum blockchain. By combining Ethereum’s decentralized ledger with IPFS’s distributed file storage, the proposed solution enhances transparency, reduces the risk of forgery, and offers a scalable and efficient method for verifying academic certificates.
The current education accreditation process poses a significant risk globally to the quality of education due to the increased falsification of academic certificates. Although previous studies have highlighted the potential benefits of blockchain technology in this context, there remains an opportunity towards a thorough investigation into the governance factors that influence the implementation of blockchain technology within the education sector. The accreditation system becomes increasingly important as a result of the emergence of a new learning ecosystem that enables the propagation of academic credits. It fosters an integrative learning approach by facilitating the accumulation of academic credits from a variety of higher education institutions, thereby promoting a learning ecosystem. The fundamental concept is to recognize the existence of a variety of learning pathways and to democratize educationTo this end, we conducted a comprehensive review of existing studies on the governance mechanisms for accreditation in the education sector using Blockchain technology. We identified 63 journal articles using four academic databases (EBScohost, Emerald, insight, Sage Journals, Scopus, Science direct) from 2018 to 2023. The literature appears devoid of proposals for a governance framework even though in the conventional paradigm such a framework is crucial in ensuring authenticity of credentials.

With the rapid development of information technology, blended learning has become a crucial aspect of modern education. However, the fragmented use of various teaching platforms, such as Xuexitong and Rain Classroom, has led to the dispersion of teaching data. This not only increases the cognitive load on teachers and students but also hinders the systematic recording of teaching activities and learning outcomes. Moreover, existing blended learning evaluation systems exhibit significant shortcomings in large-scale data storage and secure sharing. To address these issues, this study designs a blended teaching evaluation management system based on blockchain and searchable encryption. First, an on-chain and off-chain collaborative storage model is established using the Ethereum blockchain and the InterPlanetary File System (IPFS) to ensure secure and large-scale storage of student work data. Next, a role-based access control scheme utilizing smart contracts is proposed to effectively prevent unauthorized access. Simultaneously, a searchable encryption scheme is designed using AES-CBC-256 and SHA-256 algorithms, enabling data sharing while safeguarding data privacy. Additionally, the smart contract comprehensively records students’ grade information, including weekly regular scores, midterm scores, final scores, overall scores, and their rankings, ensuring transparency in the evaluation process. Based on these technical solutions, a general-purpose teaching evaluation management system (B-Education) is developed. The experimental results demonstrate that the system accurately records teaching activities and learning outcomes, improving the transparency of teaching evaluations while ensuring data security and privacy. The system’s gas consumption remains within a reasonable range, demonstrating good flexibility and usability. Educational institutions can flexibly configure course evaluation criteria and adjust the weighting of various grades based on their specific needs. This study provides an innovative solution for blended teaching evaluation, offering significant theoretical value and practical implications.

The development of cryptocurrencies continues to experience a very rapid in-crease with the prediction of average growth of more than 1 million investors every month around the world. However, it is different in Indonesia, people do not know widely what cryptocurrency is and how to invest in cryptocurrency. The Indonesian Ministry of Trade noted that in the second quarter (Q2) of 2020, cryptocurrency investors experienced an increase of up to 6.4 million investors, but when compared to the total population of Indonesia, this figure is still very far below 1%, plus economic conditions after the Coronavirus pandemic are getting worse. discourage people from investing. When viewed from the fundamental side, cryptocurrency assets can be said to be quite strong against the pandemic, compared to the stock market and mutual funds listed on the Indonesian stock exchange (IDX) which have decreased due to the coronavirus pandemic. In this study, we propose a gamification method by focusing on the introduction of cryptocurrency investments with the aim that people in Indonesia can be more familiar with and invest in cryptocurrency, the methods, and systems that we propose will at the same time reward users in the form of crypto assets to attract people to better understand the opportunities. investing in cryptocurrency.
In materials science, utilizing globally distributed data is essential for advancing materials design through technologies such as materials informatics. Achieving this requires secure, transparent, and efficient methods for managing and sharing materials data. This study explores the potential of blockchain, smart contracts, Non-Fungible Tokens (NFTs), and the InterPlanetary File System (IPFS) within the Web3 framework for managing and sharing materials data. We developed and tested a prototype data management system using a thermophysical properties dataset. This system facilitates NFT minting, data storage on IPFS, and secure, traceable ownership transfer of NFTs, enhancing traceability, transparency, and security in data sharing. Additionally, decentralized systems employing blockchain technology, smart contracts, NFTs, and IPFS effectively address vulnerabilities associated with single points of failure common in traditional centralized systems. This study offers valuable insights for future materials design, demonstrating the efficacy of blockchain and related technologies in managing and sharing materials data.
