Special Issue Information

Dear Colleagues,

Financial Technology (FinTech) has recently been considered as a hot topic that leverages technology to improve and innovate financial services and products. For example, blockchain, as a disruptive technology, has recently become synonymous with cryptocurrency (e.g., Bitcoin), but its potential has been dramatically expanding in the larger system of FinTech, such as smart contracts, P2P lending, decentralized finance (DeFi), and non-fungible tokens (NFTs).

The burgeoning FinTech requires theoretical models and innovative methodologies (e.g., forecasting, simulation, optimization, and algorithms) to address new business challenges. A FinTech business model is a plan for a financial technology business; this includes operating strategies, revenue sources, and intended customer bases. FinTech organizations generally adopt inclusive approaches to finance, enabling consumers to obtain suitable access to a wide range of financial services and products.

The current Special Issue solicits and calls for submissions concerning the research topic of “Mathematical Methods and Models of FinTech”. This includes novel research and studies on the context of FinTech for modeling, data analyses, and methodology development. Theoretical, analytical, empirical, or pedagogical articles and reviews on the application of FinTech are also invited for submission. The research topics include, but are not limited to, the following areas:

  • Data-driven financial models;
  • Innovative methodology for FinTech;
  • Cryptocurrency and investment;
  • Blockchain and smart contracts;
  • Decentralized finance (DeFi);
  • Non-fungible tokens (NFTs) and Metaverse investments;
  • Regulation, legislation, and policy making in the context of FinTech;
  • Pedagogical and educational studies on FinTech for the expanding STEM-skilled workforce.

Contributions should focus on the rigorous or robust models in the complex and challenging FinTech institution, at present, addressing the prevailing finance challenges and risks, enhancing financial performance and the ecosystem, improving the resiliency and sustainability of FinTech, and related innovative business applications.

Unsupervised classification is used in credit risk assessment to reduce human resource costs and make informed decisions in the shortest possible time. Although several studies show that support vector machine-based methods have better performance in unlabeled datasets, several factors still negatively affect these models, such as unstable results due to random initialization, reduced effectiveness due to kernel dependencies, and noise points and outliers. This paper introduces an unsupervised classification method based on a fuzzy unsupervised quadratic surface support vector machine without a kernel to avoid selecting related kernel parameters for credit risk assessment. In addition, we propose an innovative fuzzy membership function for reducing noise points and outliers in line with the direction of sample density variation. Fuzzy Unsupervised QSSVM (FUS-QSSVM) outperforms well-known SVM-based methods based on numerical tests on public benchmark credit data. In some real-world applications, the proposed method has significant potential as well as being effective, efficient, and robust. The algorithm can therefore increase the number of potential customers of financial institutions as well as increase profitability. Full article

The Metaverse allows the integration of physical and digital versions of users, processes, and environments where entities communicate, transact, and socialize. With the shift towards Extended Reality (XR) technologies, the Metaverse is envisioned to support a wide range of applicative verticals. It will support a seamless mix of physical and virtual worlds (realities) and, thus, will be a game changer for the Future Internet, built on the Semantic Web framework. The Metaverse will be ably assisted by the convergence of emerging wireless communication networks (such as Fifth-Generation and Beyond networks) or Sixth-Generation (6G) networks, Blockchain (BC), Web 3.0, Artificial Intelligence (AI), and Non-Fungible Tokens (NFTs). It has the potential for convergence in diverse industrial applications such as digital twins, telehealth care, connected vehicles, virtual education, social networks, and financial applications. Recent studies on the Metaverse have focused on explaining its key components, but a systematic study of the Metaverse in terms of industrial applications has not yet been performed. Owing to this gap, this survey presents the salient features and assistive Metaverse technologies. We discuss a high-level and generic Metaverse framework for modern industrial cyberspace and discuss the potential challenges and future directions of the Metaverse’s realization. A case study on Metaverse-assisted Real Estate Management (REM) is presented, where the Metaverse governs a Buyer–Broker–Seller (BBS) architecture for land registrations. We discuss the performance evaluation of the current land registration ecosystem in terms of cost evaluation, trust probability, and mining cost on the BC network. The obtained results show the viability of the Metaverse in REM setups. Full article
