The post Sui Launches zkAt, Privacy-First Auth for the Web3 Era appeared on BitcoinEthereumNews.com.

zkAt lets users prove authentication without revealing any policy or identity structure to the network or validators. zkAt+ allows authentication policies to be updated privately, keeping all access logic hidden from the public. The Sui development team has just announced the launch of a new technology called zkAt (Zero-Knowledge Authenticator).

It’s also said to be as efficient as traditional signatures, with the added benefit that policies can be updated without having to reveal anything to the public. Its advanced version, zkAt+, even claims to be able to do this while keeping all its logic hidden. At first glance, it sounds like technology suitable for spy movies, but now it is being prepared for the Web3 space. Big Money, Bigger Moves: Sui’s Quiet Expansion On the other hand, this comes at a time when the Sui ecosystem is experiencing a surge of interest.
