Abstract

The talent trading platform is a platform that brokers transactions such as program coding, media content production (video, music, presentation materials, etc.), design, learning, and repair. Existing talent trading platforms provide a server-client model-based service, which incurs server operating costs and arbitration labor costs for transactions, which has a disadvantage that users bear high service fees. This paper proposes a method to reduce server and database operation costs by uploading transaction information to blocks through the system as a distributed app (dApp) based on the Ethereum platform. In addition, it proposes a method to lower transaction fees by reducing the labor cost of transaction arbitrators through smart contracts. Compare and analyze the cost processing procedure and transaction fee size of the blockchain-based talent trading platform and the existing talent trading platform.

재능거래 플랫폼은 프로그램 코딩이나 미디어 콘텐츠 제작(동영상, 음악, 발표자료 등), 디자인, 학습, 수리 등의 거래를 중개하는 플랫폼이다. 기존 재능거래 플랫폼은 서버-클라이언트 모델 기반의 서비스를 제공하여, 서버를 운영하는 비용과 거래에 대한 중재 인건비가 발생하여 이용자들이 높은 서비스 수수료를 부담하는 단점이 있다. 본 논문은 이더리움 플랫폼 기반 분산앱(dApp)으로 시스템을 통해 거래 정보를 블록에 올려 서버 및 데이터베이스 운영 비용을 절감하는 방법을 제안한다. 아울러 스마트콘트랙트를 통해 거래 중재자 인건비를 절감하여 거래수수료를 낮추는 방법을 제안한다. 블록체인 기반 재능거래 플랫폼과 기존 재능거래 플랫폼의 비용 처리 절차 및 거래수수료의 크기를 비교 분석한다.
