Sui's native token, SUI, surged over 14% in the past 24 hours, significantly outperforming major cryptocurrencies like Bitcoin and Ethereum. This spike is attributed to speculation around potential privacy-preserving features on the Sui blockchain, following a research paper by Mysten Labs. The paper explores how modern blockchains can incorporate privacy features without adopting legacy privacy coin designs, suggesting a framework for privacy models across blockchains. The research, co-authored by Mysten Labs, outlines various privacy levels, from basic confidentiality to full anonymity, using cryptographic techniques like homomorphic encryption and zero-knowledge proofs. While the paper does not propose a new protocol or timeline for a privacy token, it has sparked investor interest in Sui's potential to enhance privacy features, reflecting a broader market trend towards financial privacy.
