초록
본 논문은 최근 몇 년간 암호화폐 시장에서 가장 두드러진 이슈 중 하나인 실제 자산 토큰, 즉 RWA(Real-World Assets) 토큰의 토큰 거래와 관련된 익명성 보호 문제를 다룬다. 블록체인 기술의 투명성 원칙상 거래자의 익명성을 보장하기 어렵지만, 기존 블록체인 연구에서 대체 가능 토큰(FT)의 프라이버시 보호를 위해 믹서 서비스를 이용하는 경우가 있었으며 대체 불가능 토큰(NFT)의 프라이버시 보호를 위한 선행 연구가 있었다. 그러나 FT와 NFT의 특성을 모두 지닐 수 있으며 실물 자산과 연계된 RWA 토큰은 그 구조상 어느 한 방법만을 사용해서는 익명성 보호라는 목표를 효과적으로 달성하기 어렵다. 본 논문에서는 가상의 토큰 거래 플랫폼인 ARTeX를 제안하고 거래 프로세스를 설명함으로써 RWA 토큰의 익명성 보호를 위한 방안을 분석한다.
Abstract
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.
