The rapid development of internet information technology has increased interest in e-Trade these days, but it is not activated greatly up to now. In order to promote e-Trade, it is essential to construct cooperative process such as connecting systems among trade related parties. Building e-Trade platform which is based on the infrastructure of the past trade automatic system is key point of promoting e-Trade. To do this, a study on the basic concept and specific components of e-Trade platform is needed absolutely. At this point of view, after this paper has examined domestic and foreign studies on the fundamental technologies about electronic commerce, it drew several key technologies that could be applied to e-Trade considering the current IT trend. Then it evaluates these technologies according to Technology Reference Model(TRM) of the National Computerization Agency. This will help us to show the operation strategy as well as the concept of future e-Trade platform and its composition. On the basis of the theoretical background, this paper classified NCA's technology model into 6 fields, which are application. data, platform, communication, security and management. Considering the key technologies, e-Trade platform has to be mutually connected and accept international standards such as XML. In the aspect of business side, trade relative agencies' business process as well as trading company's process has to be considered. Therefore, e-Trade platform can be classified into 3 parts which are service, infrastructure and connection. Infrastructure part is compared of circulating and managing system of electronic document, interface and service framework. Connecting service (application service) and additional service (application service) consist of service part. Connecting part is a linking mutual parts and can be divided into B2B service and B20 service. The organization operating this e-trade platform must have few responsibilities and requirements. It needs to positively accept existing infrastructure of trade automatic system and improving the system to complete e-trade platform. It also have to continuously develop new services and possess ability to operate the system for providing proper services to demanders. As a result, private sector that can play a role as TTP(Third Trust Party) is adequate for operating the system. In this case, revising law is necessary to support the responsibility and requirement of private sector.

Purpose This study aims to propose a blockchain-based platform that can guarantee enhanced trustworthiness in corporate ESG efforts, demanded by global ESG initiatives such as GRI and TCFD. Blockchain technology, recognized for its transparency and data immutability, can contribute to building trust in ESG disclosures, meeting the data transparency verification needs required by these initiatives. This research also explores the use of NFTs representing unique ESG efforts by companies, helping them in organizing and sharing ESG information with investors and consumers. Design/methodology/approach This study utilizes Hyperledger Fabric, a permissioned blockchain known for its enhanced transparency, scalability, and suitability for business transactions, to develop a blockchain platform for managing and disclosing ESG information assets in a trustworthy manner. Furthermore, it introduces the concept of ESG NFTs as a more reliable method for conveying ESG information to stakeholders, where ESG NFTs undergo verification process by third-party authenticators and evaluation by independent evaluators for credibility of ESG disclosure. Findings The use of NFTs, which has been predominantly intended for market trading in public blockchain, offers a credible means of disseminating corporate ESG status and evaluations in a permissioned blockchain, better fit for business transactions. By representing information assets as NFTs, which are tamper-proof and establish clear ownership, the proposed platform enables effective management of ESG-related information assets.

In the data economy era, various policies are being implemented to create an active data distribution environment. In South Korea, the formation of a big data distribution platform and data trading began with the launch of the Financial Data Exchange under public data governance. In the case of major advanced countries in the data field, they have built a data distribution environment based on the data broker industry for decades and have strengthened national data competitiveness through added values generated from the industry. However, behind the active data distribution through data brokers, there are numerous information security issues, which have resulted in various privacy issues and national security threats. These problems can occur sufficiently in the process of domestic financial data exchange. In our study, we analyzed various information security issues of data trading caused by data brokers and derived information security requirements to be considered when trading data. We verified whether information security requirements are well reflected in the information security policy for each transaction stage of the domestic financial data exchange. Based on the verification, measurements to strengthen information security for financial data exchange are presented in our paper.

This paper addresses the issue of anonymity protection in the trading of Real-World Asset (RWA) tokens, a prominent topic in the cryptocurrency market in recent years. The principle of transparency inherent in blockchain technology makes it challenging to ensure the anonymity of traders. Although there have been instances in existing blockchain research where mixer services have been utilized to protect the privacy of Fungible Tokens (FTs), and prior studies have explored the privacy protection for Non-Fungible Tokens (NFTs), RWA tokens, which can embody characteristics of both FTs and NFTs and are tied to physical assets, present a complex challenge in achieving the goal of anonymity protection through any single method. This paper proposes a hypothetical token trading platform, ARTeX, and describes the trading process to analyze measures for protecting the anonymity of RWA token transactions.

Recently, in the global financial transaction field, global transactions using computer systems and server hubs between foreign exchanges beyond the one-dimensional offline transactions and two-dimensional online transactions have been actively conducted. In the previous research by Lee Hyung-wook and Lee Min-jae (2018), as the globalization has accelerated following the development of digital technology and the expansion of ubiquitous communication network, the role of companies, the attribute of economic value creation and economic structure are being reorganized. It is said that O2O (Online to Offline) transactions are increasing due to the development. As a result, a new financial transaction paradigm is emerging that solves the inconveniences of existing financial services and enhances speed and convenience. Considering the global network trend and the rapidly developing and evolving digital bank environment, the necessity of utilizing the business platform model is emerging. However, despite this necessity, there are very limited cases in which such an attempt has been applied in practice. Accordingly, this study seeks to explore the business platform of the new financial transaction system. Specifically, the case study systematically examines the actual implementation of a unique network connection model with Koscom's global investment bank, which is currently in charge of the domestic financial transaction system, and improves ICT innovation performance and process through this. I would like to suggest a solution. In particular, this study analyzed a variety of business model construction and use cases by pursuing a platform connection with digital banks, which has recently been increasingly in demand. Therefore, this study intends to pursue the original and long-term profitability of the company by utilizing ICT innovation and platform business model, and also analyzes the convenience and excellence of trading for institutional and individual investors using the platform of digital bank. The implications of this study are significant in that it explores and explores the actual cases of ICT innovation and additional digital bank platform-connected business models based on this, and suggests a unique and preemptive business strategy of the company in the future.
