The financial industry continues to evolve, specifically in payment processing. Payment processing is at the forefront of technological advancements, significant growth, and constant change. Companies desiring to grow their consumer base must remain current with trends and developments in payment processing. Payment processing has entered a new era of technology advancements inspired by AI, ML, and cloud computing, impacting operations and transforming businesses in today’s marketplace. The banking industry faces fierce competition from agile Fintech players that leverage technology to deliver services and new offerings faster and cheaper. Significant public sector funding catalyzed the growth of open and responsive payments ecosystems. Innovative combination models like Buy now, pay later (BNPL) and crypto-currency are springing forth, shifting risks from the lenders as well as intermediaries to the consumers, end-users, and providers. In blue-ocean areas such as e-Commerce, instant, cross-border payments, and digital assets, competition is not only intense, but the playing field is constantly growing and redefining itself. Vendors in on-and-off line electronic payments across different ecosystem parameters—service provider, regulation, traffic, payment format—have the latitude to partner or compete with each other, creating a complex environment defined by misaligned incentives on legacy systems, incomplete data, and bureaucratic inertia. On the other hand, irrespective of the payment type, frauds are nearing pre-global-financial-crisis levels, and direct losses are growing exponentially. Payment vulnerabilities translating into cyber risks and data breaches loom large, and hacking the supply chain has become a top concern for enterprises. Federated Financial Institutions, Private Sector Players, Financial Data Exchanges, and RegTech will need to collaborate and invest in differentiated technology capabilities to secure their pieces of a slim pie. It would require immediate injections of cash upfront, time To Income (TTI) on legacy IT assets, acquisitions of technology providers, setting up scalable and proactive test environments, and a radical shift in the approach to assessing partners and vendors. Growing customer expectations for payments to flow instantly are forcing banks to intensify their innovation programs and invest in real-time payment systems. There are dedicated task forces at supervisors and regulators worldwide Engineering Distributed-control and Self-governed Payment Systems; Global Consensus Standardization of Payment Internet Protocols; and morphing payment systems into programmable platforms. Banks are even incentivized to capture new geographies and market segments by embracing Public Open Payment Protocols, Distributed-ledger Technology, and Edge-based Devices for Processing Payment Signals with control residing at the edge.

Decentralized exchanges DEXs allow traders to express their willingness to pay for quick execution through a public priority fee bidding mechanism. We provide empirical evidence that high-fee DEX trades are more informative and contribute more to price discovery. Using address-level blockchain transaction data, we show that informed traders persistently bid higher fees to secure early execution, revealing a strong willingness to pay for execution priority. Further, analysis of Ethereum mempool data demonstrates that informed traders employ a "jump bidding" strategy, placing high initial bids to deter potential competitors.

The advent of blockchain technology has revolutionized the way decentralized applications (dApps) and smart contracts are developed and deployed. However, the barrier of gas fees continues to hinder mass adoption, especially in resource-constrained environments. This paper proposes a novel, practical model for gasless smart contract transactions by integrating facial recognition technology within blockchain ecosystems. Our approach leverages zero-knowledge proofs and meta-transaction protocols to enable trustless authentication and transaction signing through biometric facial data, thereby eliminating the need for users to maintain a cryptocurrency balance for transaction execution. The proposed model is built on a multi-layered architecture that incorporates a decentralized identity (DID) framework, a biometric verification engine, and a relayer network that pays the gas on behalf of the user. Using facial recognition as a biometric key, users can trigger and authorize smart contract functions without direct wallet interaction or private key exposure. The system enhances security by utilizing advanced liveness detection and encrypted facial signature hashing, preventing spoofing and ensuring that only legitimate users gain access to the network. Furthermore, it supports user onboarding via identity verification processes that comply with global KYC (Know Your Customer) standards, thus bridging the gap between user accessibility and regulatory requirements. A simulation environment was developed using Solidity, OpenZeppelin libraries, AWS Rekognition for facial analysis, and the Biconomy SDK for meta-transactions. Performance metrics indicate significant improvements in user onboarding time, cost-efficiency, and fraud prevention compared to traditional models. The model also reduces environmental impact by lowering the computational overhead associated with repeated gas-based authentication. This paper provides a blueprint for developers, policymakers, and fintech stakeholders to adopt gasless blockchain frameworks supported by biometric security. It presents a scalable and user-friendly solution that could unlock broader blockchain adoption in finance, healthcare, and identity management sectors. The fusion of facial recognition with smart contract automation signifies a leap towards a more inclusive, secure, and cost-efficient decentralized future.

There is a lot of hope that blockchain technology may be used to standardize money transactions and increase access to banking. It is believed that regulators and industry professionals have looked into the possibility of using blockchain technology to modernize and even replace the infrastructure that currently supports international payments and remittances, such as correspondent banking, in order to ensure that transactions can be verified and recorded using blockchain technology in a distributed ledger. The purpose of this study was to analyze how blockchain technology has helped to include previously underserved populations in the mainstream financial system, and to remark on the best practices and lessons learned from sustainable development. Using a systematic literature review, the study discovered the many ways in which blockchain technology can facilitate digital financial inclusion, including its application in financial transactions, its utility as a tool for increasing financial savings, its use in the provision of credit, and its application in the provision of insurance. According to the findings, even though the global goals do not specifically target financial inclusion, providing access to financial services for the majority of the population is a critical enabler for several of the global goals. Therefore, the study concluded that sustainable development can be ensured on many fronts if the technology behind blockchains can be successfully used to improve financial inclusion. If governments, especially in developing countries, are serious about increasing citizens’ access to financial services, they must prioritize blockchain investment.

Abstract:\n\n \n\nSo far, blockchain has been well acknowledged for its potential uses in the financial and banking industries. As a decentralized and distributed technology, blockchain, on the other hand, may be used as a powerful tool for a wide range of everyday applications. Among the many applications sectors where blockchain is expected to have a significant influence, finance and banking is one of the most important. In the contemporary financial and banking systems, it produces a broad variety of options and possibilities. As a result, the purpose of this paper is to investigate the possible uses of blockchain technology in present financial and banking systems, as well as to emphasize the most critical needs for such systems, such as trust less and transparent financial and banking systems. In addition, this article outlines the hurdles and roadblocks that must be overcome before blockchain technology can be successfully used in financial and banking institutions. In addition, we present the smart contract for blockchain-based financial and banking systems, which is critical for setting pre-defined agreements among multiple customers.

This study aimed to determine the effect of behavior factors and social demography on the investment decision in cryptocurrency in the Greater Jakarta area. The method used in this study is partial least square (PLS) using the SmartPLS software application. The behavior factor variables used in this study are overconfidence, herd behavior, subjective norm, and awareness variables. This study also used social demography moderating variables in age, gender, occupation, education, and investment experience on 400 respondents in the Greater Jakarta area. The test results show that only overconfidence and awareness variables have a significant positive effect on decisions to invest in cryptocurrency and subjective norms variables that have no significant positive effect but can be moderated by social demographic factors such as age and investment experience. In addition, other variables have no significant positive effect. They cannot be moderated by social demographic factors such as age, gender, occupation, and investment experience on the decisions of cryptocurrency investors in Greater Jakarta area. Our study contributes to developing knowledge, insight, skills and analyzing researchers, especially regarding the influence of behavioral factors and social demography on investment decisions in cryptocurrency.

The growth of the enterprise blockchain research supporting supply chain management calls for investigations of their impact and mindfulness of their design, use cases, and pilots. With a blockchain design for the Proof of Delivery (PoD) process management, this paper contributes to learning about performance measurement and the transaction costs implications during the development and application of smart contracts. An experimental design science approach is applied to develop an open-source blockchain to explore ways to make the delivery processes more efficient, the proof of delivery more reliable, and the performance measurements more accurate. The theory of Transaction Costs is applied to evaluate the cost implications of the adoption of smart contracts in the management of the PoD. The findings show that smart contracts make the delivery processes more efficient and proof of delivery more reliable. Yet, the methods and metrics are too complex and qualitative, limiting the smart contract’s capability to measure performance. Our findings indicate potential transaction costs reduction by implementing a blockchain-based performance measurement. The complexities of the delivery process and proof of delivery call for pre-contractual steps to identify the processes and performance metrics to design blockchains. Smart contracts need further development and digital aids to handle qualitative inspections and proof of delivery generation during the delivery process. The blockchain requires the system’s capacity to record off-chain transactions, such as in case of disputes resolutions. The authors extended blockchain research beyond the theoretical level, designing an open-source blockchain for supply chain management within the use case, pilot design, and case study.

최근 가상화폐 거래가 활발하게 이루어지고 결제 수단으로 이용이 확대되면서 디지털 통화에 대한 정부와 투자자의 관심이 확대되고 있다. 현재 국내외 많은 문헌들이 비트코인의 법적, 제도적인 측면과 블록체인 기술 등 이용의 측면에서 초점을 맞추고 있다. 반면 금융시장의 관점에서 가상화폐 시장의 효율성을 분석한 연구는 상대적으로 매우 부족한 상황이다. 이에 착안하여 본 연구에서는 가상화폐 가격의 시계열적인 특성을 잘 이해하기 위해 장기기억과 시장효율성을 분석하고 있다. 현재 가장 널리 알려진 가상화폐 중의 하나인 비트코인, 이더리움, 카르다노, 테더, 도지코인 등 5개 가상화폐를 분석대상으로 하였다. Variance Ratio, Conventional R/S, Modified R/S, GPH 검정 등을 실시한 결과, 비트코인, 이더리움은 시장의 효율성을 보여주는 증거가 발견되었지만 카르다노, 테더, 도지코인은 시장의 비효율성을 보여주는 결과가 일부 나타났다. 하지만, 분석 기간을 코로나19 팬데믹 이후로 한정하면 카르다노, 테더, 도지코인의 경우에도 모두 효율적인 시장으로 볼 수 있는 증거들이 발견되었다. 이러한 분석 결과는 현재 카르다노, 테더, 도지코인의 경우에도 점차 효율적인 시장으로 변화하는 과정에 있다는 점을 시사한다.

본 연구는 현행 암호화폐 회계처리의 문제점을 국내외 기업들의 사례로 파악하는 사례연구이다. 최근 암호화폐에 대한 기업들의 관심이 늘고 있으나, 암호화폐의 실질을 적절히 반영하기 위한 기준서의 제정 및 개정은 이루어지지 않고 있다. IFRS 해석위원회는 암호화폐를 재고자산 혹은 무형자산으로 분류하고 기존의 기준서에 따라 회계처리 하도록 하고 있다. 하지만 이러한 해석은 기존 기업들이 경영진의 판단에 따라 개발해 사용하고 있던 회계처리와는 상이하고, 거래의 실질을 반영하지 못한다. 선행연구에 따르면 암호화폐는 그 실질에 있어서 통상적인 판매목적으로 보유할 경우 재고자산, 그 중에서도 특히 일반상품과 유사하다. 반면 투자목적으로 보유할 경우 파생상품의 기초가 되는 일반상품이나 금융자산 중 당기손익-공정가치측정(FVTPL) 금융자산과 유사하다. 따라서 본 사례연구는 실제 기업들의 분석을 통해 현행 암호화폐 회계처리 적용 시 발생 가능한 한계 및 문제점들을 파악한다. 사례분석 대상기업은 미국의 마이크로스트래티지, SPDR 금 신탁, 번지, 그리고 한국의 한빛소프트와 두나무이다. 본 연구에서는 사업목적과 투자목적에 따른 암호화폐 회계처리를 위해 ‘투자자본자산’의 개념을 제안하고, 무형자산 기준서 개정 역시 제안한다. 마지막으로 위 연구를 바탕으로 암호화폐 보유기업 감사 시 현재 고려해야 할 사항들을 제시한다.
