Morocco's Vision 2030, known as Maroc Digital 2030, aims to position the country as a regional leader in digital technology by boosting digital infrastructure, fostering innovation, and advancing digital skills. Complementing this initiative, the Pacte ESRI 2030 strategy, launched in 2023, seeks to transform the higher education, research, and innovation sectors by integrating state-of-the-art digital technologies. In alignment with these national strategies, this paper introduces BlockMEDC, a blockchain-based system for securing and managing Moroccan educational digital certificates. Leveraging Ethereum smart contracts and the InterPlanetary File System, BlockMEDC automates the issuance, management, and verification of academic credentials across Moroccan universities. The proposed system addresses key issues such as document authenticity, manual verification, and lack of interoperability, delivering a secure, transparent, and cost-effective solution that aligns with Morocco's digital transformation goals for the education sector.
There is a huge demand to ensure the compliance of smart contracts listed on blockchain platforms to safety and economic standards described in natural languages. Today, manual efforts in the form of auditing are commonly used to achieve this goal. ML-based automated techniques have the promise to alleviate human efforts and the resulting monetary costs. However, unlike other domains where ML techniques have had huge successes, no systematic ML techniques have been proposed or applied to smart contract auditing. We present SC-Bench, the first dataset for automated smart-contract auditing research. SC-Bench consists of 5,377 real-world smart contracts running on Ethereum, a widely used blockchain platform, and 15,975 violations of standards on Ehereum called ERCs. Out of these violations, 139 are real violations programmers made. The remaining are errors systematically injected by us to reflect the violations of different ERC rules. We evaluate SC-Bench using GPT-4 by prompting it with both the contracts and ERC rules. In addition, we manually identify each violated rule and the corresponding code site (i.e., oracle) and prompt GPT-4 with the information asking for a True-or-False question. Our results show that without the oracle, GPT-4 can only detect 0.9% violations, and with the oracle, it detects 22.9% violations. These results show the potential room for improvement in ML-based techniques for smart-contract auditing.

SMT-based verification of low-level code requires modeling and reasoning about memory operations. Prior work has shown that optimizing memory representations is beneficial for scaling verification—pointer analysis, for example can be used to split memory into disjoint regions leading to faster SMT solving. However, these techniques are mostly designed for C and C++ programs with explicit operations for memory allocation which are not present in all languages. For instance, on the Ethereum virtual machine, memory is simply a monolithic array of bytes which can be freely accessed by Ethereum bytecode, and there is no allocation primitive. In this paper, we present a memory splitting transformation guided by a conservative memory analysis for Ethereum bytecode generated by the Solidity compiler. The analysis consists of two phases: recovering memory allocation and memory regions, followed by a pointer analysis. The goal of the analysis is to enable memory splitting which in turn speeds up verification. We have implemented both the analysis and the memory splitting transformation as part of a verification tool, CertoraProver, and show that the transformation speeds up SMT solving by up to 120× and additionally mitigates 16 timeouts when used on 229 real-world smart contract verification tasks.
Recently, smart contracts have played a vital role in automatic financial and business transactions. To help end users without programming background to better understand the logic of smart contracts, previous studies have proposed models for automatically translating smart contract source code into their corresponding code summaries. However, in practice, only 13% of smart contracts deployed on the Ethereum blockchain are associated with source code. The practical usage of these existing tools is significantly restricted. Considering that bytecode is always necessary when deploying smart contracts, in this article, we first introduce the task of automatically generating smart contract code summaries from bytecode. We propose a novel approach, named Smart Contract Bytecode Translator ( SmartBT ) for automatically translating smart contract bytecode into fine-grained natural language description directly. Two key challenges are posed for this task: structural code logic hidden in bytecode and the huge semantic gap between bytecode and natural language descriptions. To address the first challenge, we transform bytecode into Control-Flow Graph (CFG) to learn code structural and logic details. Regarding the second challenge, we introduce an information retrieval component to fetch similar comments for filling the semantic gap. Then, the structural input and semantic input are used to build an attentional sequence-to-sequence neural network model. The copy mechanism is employed to copy rare words directly from similar comments, and the coverage mechanism is employed to eliminate repetitive outputs. The automatic evaluation results show that SmartBT outperforms a set of baselines by a large margin, and the human evaluation results show the effectiveness and potential of SmartBT in producing meaningful and accurate comments for smart contract code from bytecode directly.
Small and medium-sized enterprises (SMEs) are the cornerstone of the European eDaconomy, representing 99.8% of all businesses and providing 66% of employment. Despite their critical role, SMEs face significant challenges in accessing traditional financing, particularly in the aftermath of the 2008 financial crisis, which led to a reduction in riskier lending by banks. Crowdfunding has emerged as a viable alternative, offering a decentralized and democratized avenue for raising capital, especially through platforms powered by blockchain technology.This paper explores the potential of blockchain technology (BCT) to revolutionize crowdfunding within the European Union (EU), addressing the critical financial needs of SMEs. BCT enhances transparency, trust, and efficiency in crowdfunding by enabling features such as tokenization, smart contracts, and decentralization. These innovations offer solutions to longstanding issues in traditional finance, such as fraud, information asymmetry, and the reliance on intermediaries.However, the paper also highlights the limitations and challenges of crowdfunding in Europe, particularly the disparities in crowdfunding trends between the UK, Nordic countries, and the rest of the EU. Financial data from 2018 and projections for 2023 reveal that while the number of crowdfunding campaigns in the EU is growing, the per-campaign value remains significantly lower compared to the UK, reflecting a continued focus on smaller-scale investments.The integration of BCT into crowdfunding practices presents both opportunities and obstacles. Although it offers a promising path to more efficient and secure funding mechanisms, the successful implementation of BCT will require coordinated efforts from governments, regulatory bodies, financial institutions, and technology developers to navigate the complex legal and technological landscape.In conclusion, while blockchain-based crowdfunding has the potential to reshape SME financing in Europe, realizing its full benefits will demand proactive engagement with emerging challenges and continuous adaptation to evolving regulatory frameworks.
The substantial value held by smart contracts (SCs) makes them an enticing target for malicious attacks. The process of fixing vulnerabilities in SCs is intricate, primarily due to the immutability of blockchain technology. This research paper introduces a systematic literature review (SLR) that evaluates rectification systems designed to patch vulnerabilities in SCs. Following the guidelines set forth by the PRISMA statement, this SLR meticulously reviews a total of 31 papers. In this context, we classify recently published SC automated repair frameworks based on their methodologies for automatic program repair (APR), rewriting strategies, and tools for vulnerability detection. We argue that automated patching enhances the reliability and adoption of SCs, thereby allowing developers to promptly address identified vulnerabilities. Furthermore, existing automated repair tools are capable of addressing only a restricted range of vulnerabilities, and in some cases, patches may not be effective in preventing the targeted vulnerabilities. Another key point that should be taken into account is the simplicity of the patch and the gas consumption of the modified program. Alternatively, large language models (LLMs) have opened new avenues for automatic patch generation, and their performance can be improved by innovative methodologies.

Blockchain technology offers transformative benefits for waqf by enhancing transparency, security, and efficiency. Its decentralized ledger system allows for independent transaction verification, reduces central authority risks, and improves accountability. However, while the potential benefits are significant, the success of blockchain-based waqf initiatives hinges on the level of trust that stakeholders place in this technology. Therefore, the study aims to examine the effect of trust in blockchain technology on the intention to adopt waqf blockchain with insight from importance-performance map analysis to better understand the relations between trust and intention. The study adopted a survey research design and data was collected through questionnaires distributed throughout Malaysia. The collected data were then analyzed using Smart-PLS software. The results of the analysis indicate a strong positive relationship between trust in blockchain technology and the intention to adopt waqf blockchain. However, the importance-performance map analysis shows a critical disparity exists between user expectations and actual performance, especially regarding the transaction process, which scored the lowest in performance. This implies a need to focus on improving the transaction process to align with user expectations.

Bitcoin remains a popular investment choice despite the regulatory obstacles and failures of many crypto firms. This intriguing behavior of investors necessitates calls for more in-depth research. This study explores the underlying motivations behind the intention to invest in Bitcoin by considering inaction regret aversion, overconfidence bias, herding, risk affinity, profit expectancy, perceived ease of investing, and social media influence in shaping the investors’ attitude towards investing in Bitcoin and consequently on behavioral intention to invest in Bitcoin. The study employs PLS-SEM and mediation analysis on a sample of 439 individuals from India with no history of cryptocurrency trading or investment. Path analysis demonstrates that inaction regret aversion, risk affinity, profit expectancy of Bitcoin, perceived ease of investing in Bitcoin, and social media influence are significant positive predictors of attitude toward investing in Bitcoin. Notably, profit expectancy remains the most relevant variable in the stated context. Attitude toward investing in Bitcoin positively and significantly influences the behavioral intention to invest in Bitcoin. The current study also indicates the significance of attitude as a mediator in the mentioned context.
‘If buying isn’t owning, then piracy isn’t stealing,’ is a common refrain on the internet. With this in mind, the article delves into the landscape of property rights concerning digital assets, debunks common misconceptions and clarifies their legal position in the evolving economy. Through an analysis of their intangible nature, the article argues that digital assets are more akin to intellectual property than to tangible assets. Drawing on a spectrum of case law recognising digital assets as objects of property rights, it examines property law in various legal systems, ranging from common law jurisdictions such as the United States, the United Kingdom and New Zealand, to civil law systems such as Germany, China and Poland. It also explores the notion of digital assets as contractual claims and navigates the complexities of conflicts of laws, advocating for a universal framework to protect digital property and data ownership beyond the realm of Non-Fungible Tokens (NFTs).

This study investigated the effect of distributed ledger technology (DLT) factors on eliminating financial reporting errors (FREs) in quoted Nigerian banks. Using an exploratory survey design, data was collected from 300 employees of 14 quoted banks involved in financial reporting. DLT factors of public, private, hybrid, and blockchain were examined as independent variables affecting the dependent variable of FRE elimination. Descriptive analysis showed that all DLT types were perceived as highly effective for error reduction. Correlation analysis revealed strong positive relationships between DLT factors and FRE mitigation. Regression modeling found that hybrid DLT had the largest impact on error elimination, followed by private, public, and blockchain DLT. Together, the DLT factors explained 98.1% of the variance in FRE reduction. The results statistically established the significant positive effects of DLT factors on eliminating prevalent FREs like principle, omission, entry, disclosure, and reversal errors. Key contributions include providing robust empirical evidence that leveraging DLT, especially hybrid DLT, can eliminate common financial reporting errors in Nigerian banks. The pioneering study expands conceptualizations, theories, and literature regarding DLT's potential to comprehensively transform financial reporting accuracy. It offers important implications for policy, practice, and research on regulating, adopting, and studying DLT solutions to address persistent financial statement errors undermining stakeholder trust in Nigeria's banking sector. The study concludes by strongly recommending for policy and, in practice, the regulation and full adoption of DLT for the elimination of FREs in Nigeria.

Blockchain technology has emerged as a transformative force with the potential to greatly improve financial inclusion, especially among underbanked and unbanked communities. Financial inclusion refers to the accessibility and availability of financial services for all individuals, yet billions remain excluded from formal financial systems. Traditional banking often overlooks these populations due to geographic barriers, high transaction fees, and strict regulatory frameworks. Blockchain provides a decentralized, secure, and transparent platform for financial transactions, allowing individuals to access services without relying on traditional banking infrastructure. By removing intermediaries, blockchain lowers transaction costs, accelerates service delivery, and enhances transparency. It enables peerto-peer transactions, facilitates cross-border remittances, and supports micro-lending through smart contracts, thereby broadening access to vital financial services. Furthermore, the immutable and auditable characteristics of blockchain foster trust in financial systems, particularly in regions plagued by weak institutions or corruption. However, despite its promise, blockchain faces substantial hurdles such as regulatory uncertainties, limitations in technological infrastructure, and cryptocurrency volatility that impede widespread adoption. Integrating blockchain with complementary technologies like mobile banking and the internet could further enhance its role in advancing financial inclusion. This paper investigates the diverse effects of blockchain technology on financial inclusion while critically analyzing both its potential advantages and the challenges that must be addressed to fully leverage its capabilities in promoting global financial access and equity.

Blockchain technology and Decentralized Finance (DeFi) are revolutionizing traditional banking and financial systems by eliminating the need for intermediaries, reducing transaction costs, and fostering more inclusive financial services. Unlike centralized systems that rely on trusted third parties such as banks and payment processors, DeFi operates on decentralized networks powered by blockchain technology. This innovation enables peer-to-peer financial transactions, smart contracts, and automated protocols, allowing for secure and transparent exchanges without the need for intermediaries. The disruption caused by DeFi challenges the conventional financial system by providing users with greater control over their assets and access to a broad range of financial services, including lending, borrowing, trading, and asset management. Through blockchain’s inherent features such as immutability, cryptographic security, and transparency, DeFi systems ensure trust less transactions, reducing the risk of fraud and errors while enhancing privacy. This paper explores the transformative potential of blockchain and DeFi in reshaping the financial landscape, addressing key benefits such as financial inclusion, the democratization of wealth, and more efficient global financial markets. However, the rise of DeFi also brings challenges such as regulatory uncertainty, technological risks, and the need for robust security measures to prevent fraud and ensure user protection. As DeFi continues to evolve, its impact on the future of finance is profound, offering both opportunities and risks that must be carefully navigated.
