Recently, the blockchain platform is changing the art market. Changes are taking place in many areas, including artists, collectors, art investors, and auction. The platform that provides distribution history information on artworks on a blockchain basis can be used when information on the work history is suspected or needs verification, and can be used to manage the distribution history information of stolen and lost artworks and confiscated artworks by the police. Several companies currently operate these platforms, but they operate various blockchain platforms according to their contents. In this paper, we will compare and analyze features of artworks blockchain platform.

Most works of art are done through brokers, and transaction details are not disclosed to the public and are always at risk of tampering. To solve these problems, many Artworks Blockchain Platforms that apply blockchain technology to art transactions are being used. Several companies are currently operating these platforms, but since various blockchain platforms are operated according to the content, the operating methods of each platform are different, and a related model is needed to solve these problems due to compatibility issues between platforms. In this paper, we collect the latest Artworks Blockchain Platforms data, and based on this, we will create and analyze the Color Petri net model of Artworks Blockchain Platform.

The purposes of the study are threefold: (1) develop key successful factors of blockchain platform for micro-enterprises based on Balanced Scorecard (BSC), (2) find out the correlation between the key successful factors of blockchain platform for micro-enterprises, and (3) understand the perception of micro-enterprise blockchain and the difference between theoretical guidance and practical application. This study combines Interpretative Structural Modeling Method, (ISM) and Decision-Making Trial and Evaluation Laboratory (DEMATEL) to analyze the causal relationships and hierarchical structures of the 12 key successful factors of blockchain platform for micro-enterprises and understand the correlation between factors. The 12 key successful factors developed based on the four perspectives of the Balanced Scorecard, and the questionnaire designs based on the concept of DEMATEL, and then analyzed data by DEMATEL and ISM methods to understand the correlation between key factors. The research results show that the key successful factors of blockchain platform for micro-enterprises include "brand equity", "security and anti-counterfeiting", "sales growth", "transparency and clear", "trust", "consensus mechanism", "traceability", "consistency", "tracking", "innovation management", "international", "organizational adaptation", in which consumer "trust" plays an important role. Micro-enterprises can use blockchain to expand the market, provide customers with better service quality, and bring sales growth to micro-enterprises.

In this paper, we present a certificate management platform for performance assessment during recruitment using blockchain. Applicants are awarded certificates according to a predetermined level of progress based on their performances. All certificates are stored on a recruitment management platform that serves as an environment for storing and presenting all awarded certificates. The hashed information of all the certificates are stored in the blockchain, and once stored, the contents cannot be tampered with. Therefore, anyone can check the validity of the certificates using this blockchain. Our proposed platform will be useful for recruitment and application management, career management, and personal history maintenance.

정보통신기술의 융합에 따른 4차 혁명의 파고가 거세지고 있는 가운데 블록체인 기반 플랫폼의 활용범위가 크게 확장되고 있다. 이에 이 연구는 블록체인 기반 금융 플랫폼에 초점을 맞춰 플랫폼 이용자의 수용의도를 결정하는 요인을 탐색하고자 하였다. 특히, 이 연구는 블록체인 기반 플랫폼에 대한 이용자 수용의도에 관한 결정요인 탐색에서 금융 플랫폼을 대상으로 했다는 점 그리고 플랫폼 이용자 수용의도가 남녀 간 성별 차이가 있는지를 확인하는데 연구의 초점을 맞춰 살펴봤다는 점에서 의의가 있다. 이는 블록체인과 관련해 이용자의 수용의도를 탐색하는 것은 금융업계뿐 아니라 블록체인 기술 개발자에게 매우 중요한 사안이기 때문이다. 연구방법은 474명(남성 262명, 여성 212명)이 참여한 설문조사 결과를 토대로 구조방정식 모형을 적용하여 블록체인 기반 플랫폼의 이용자 수용의도 구조를 탐구하였다. 연구결과, 블록체인 기반 금융 플랫폼 이용자의 수용의도 결정요인으로서 혁신성, 편의성, 보안성, 선호성이 작동하는 것으로 나타났고, 이중 혁신성과 편의성 요인에서 남녀 성별 차이에 따른 수용의도 결정요인이 차이가 있음이 확인되었다.

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.

Purpose The purpose of this study was to investigate the intention of using a news media platform using block chain through media company workers in a situation where various platform services using block chain are being newly released in the media industry. Therefore, in this paper, we intend to explore the development direction of the news media platform service using the block chain in the future by deriving implications through the characteristics of the block chain, user characteristics, and self-determination factors. Design/methodology/approach This study conducted a survey on the main characteristics of blockchain, user characteristics, self-determination, resistance to innovation, etc., and designed a research model by integrating factors on the continuity of intention to use the news media platform. Findings According to the empirical analysis result, in this study, it was confirmed that the intention to use the blockchain news media platform is significantly related to decentralization, which is a characteristic variable of the blockchain, perceived risk, which is a user characteristic variable, and competence and relationship, which is a self-determination variable. In addition, it was confirmed that it affects the perceived ease of use with respect to the intention to use. In addition, in this study, news writers write more careful articles as they cannot edit articles once written, which can contribute to improving the quality of news content.

As the demand for distance education increases, interest in the management of learners' rights is increasing. Blockchain technology is a technology that guarantees the integrity of the learner's learning history, and enables learner-led learning control, data security, and sharing of learning resources. In this paper, we proposed a blockchain technology-based learning management system based on Hyperledger Fabric that can be verified through permission between nodes among blockchain platforms. Learning resources can be shared differentially according to the learning progress. Also the percentage of individual learners that can be managed. As a result of the study, the superiority of the platform in terms of convenience compared to the existing platform was demonstrated. As a result of the performance evaluation for the research in this paper, it was confirmed that the convenience was improved by more than 5%, and the performance was 4-5% superior to the existing platform in terms of learner satisfaction.

블록체인 기반의 플랫폼은 거래기록의 분산처리 및 암호화 기술 적용을 통해 데이터 무결성, 신뢰성, 보안성을 확보할 수 있다. 기존 지식공유 플랫폼에서는 정보 비대칭, 중앙화 등의 이유로 창출된 지식이 충분히 공유되거나 활용되지 못하는 문제점이 존재하지만 이에 관한 연구는 그동안 거의 이루어지지 않았다. 본 연구에서는 블록체인 기술, 토큰 이코노미, 지식공유, 동기이론, 사회적 교환 이론의 선행연구를 바탕으로 블록체인 기반의 지식공유 플랫폼에 대한 사례 연구와 발전 가능성에 대하여 살펴보고자 한다. 블록체인 기반의 플랫폼은 정보 비대칭성을 해소하고, 지식공유 흐름의 일원화 및 탈중앙화를 통한 권한 집중화 배제를 통해 불필요한 업무 절차를 간소화하고, 플랫폼이 생산하는 지식에 대한 접근과 활용을 강화하여 지식공유의 활성화에 이바지할 수 있을 것으로 기대한다.
