Aztec Launches Tierra Upgrade to Fix Security Flaws and Double Privacy Proof Speeds

Aztec Foundation, behind the Ethereum privacy Layer 2 network Aztec, has launched the Tierra (Alpha V6) upgrade to fix security vulnerabilities, including a critical flaw found in V5, and introduce an AI-based security testing system. According to Odaily, the upgrade doubles the speed of generating privacy transaction proofs, reducing the process to about one second on local devices, and cuts the time for Ethereum messages to reach Aztec from an average of about two minutes to as little as 12 seconds. Aztec said its decentralized architecture requires the entire network to upgrade to address critical vulnerabilities, rather than allowing a centralized operator to apply a fix independently. The network has more than 3,000 validators and no centralized sequencer or privileged viewing keys, the team said.
