Sui outperforms major cryptocurrencies as Mysten Labs rolls out enhanced privacy tools.

Sui Surges 14% on Privacy Research, Outperforming Bitcoin and Ether

Layer 1 blockchain Sui (SUI) jumped 14% in the past 24 hours, sharply outpacing Bitcoin (BTC $91,661) and Ether (ETH $3,200), which rose roughly 1% each. The move made SUI the top-performing large-cap token of the day, highlighting a token-specific catalyst rather than broader market momentum.

The rally follows a research paper co-authored by Mysten Labs, Sui’s core developer, which explores how modern blockchains can incorporate privacy features without adopting legacy privacy coin designs. The paper categorizes privacy into levels, from basic confidentiality — hiding transaction amounts — to full anonymity, which obscures sender and receiver identities.

Sui is positioned within the account-based model, alongside Ethereum and Solana. The study details how confidential balances, limited anonymity sets, and sender-receiver unlinkability could be implemented using cryptography such as zero-knowledge proofs and homomorphic encryption, while noting trade-offs like higher computational demands and regulatory considerations.

Privacy Coins Gain Traction

Privacy-focused assets saw growing demand in late 2025. Coins like Zcash and Monero outperformed broader markets amid macro pressures, reflecting a rotation toward digital cash — assets designed for spending rather than yield, where zero-knowledge proofs allow confidential transactions without slowing settlement or compromising compliance.

While the paper does not propose a Sui privacy token or new technology, investors see it as a signal of potential future developments, driving renewed interest in privacy-centric crypto.
