ARTeX: Anonymity Real-world-assets Token eXchange
Jaeseong Lee, Junghee Lee
TL;DR
This paper tackles privacy concerns in Real-World Asset (RWA) token markets by proposing ARTeX, a token trading platform designed to protect trader anonymity through unlinkability and a secure delivery channel. It details the RWA concept, its ERC3643-based Identity Registry Contract, and the distinction between anonymity and privacy, arguing that hiding trader identities is essential for trust in high-value trades. The ARTeX workflow comprises five stages—from listing and auction to settlement and secure post-sale delivery—along with KYC requirements and a mechanism to prevent direct linkability on-chain. The study also analyzes why mixer services are unsuitable for RWA trading and discusses limitations and future work to enhance legality and safety while preserving anonymity in real-world asset transactions.
Abstract
This paper addresses one of the most noteworthy issues in the recent virtual asset market, the privacy concerns related to token transactions of Real-World Assets tokens, known as RWA tokens. Following the advent of Bitcoin, the virtual asset market has experienced explosive growth, spawning movements to link real-world assets with virtual assets. However, due to the transparency principle of blockchain technology, the anonymity of traders cannot be guaranteed. In the existing blockchain environment, there have been instances of protecting the privacy of fungible tokens (FTs) using mixer services. Moreover, numerous studies have been conducted to secure the privacy of non-fungible tokens (NFTs). However, due to the unique characteristics of RWA tokens and the limitations of each study, it has been challenging to achieve the goal of anonymity protection effectively. This paper proposes a new token trading platform, the ARTeX, designed to resolve these issues. This platform not only addresses the shortcomings of existing methods but also ensures the anonymity of traders while enhancing safeguards against illegal activities.
