Aztec rolls out Tierra V6 upgrade for its Ethereum privacy network

What sources claim

• The Block reported that Aztec Foundation said Tierra V6 fixes earlier security issues and doubles the speed of private transaction proof generation.
• Decrypt reported that the Tierra upgrade resolves a critical bug from the prior version, adds formal verification, and an AI-powered testing harness.

Still unresolved

• What specific security issues from earlier versions Tierra V6 fixes, and what an Aztec Foundation statement or technical post-mortem would confirm.
• How the doubling of private transaction proof generation speed was measured, and what benchmark data or documentation would confirm the figure.

Evidence levels describe source coverage, not the probability that a report is true. Price moves and their timing cannot establish a cause; minute samples show an observed interval and alert thresholds are heuristics. Explanations are model-assisted, with citations and figures checked. Source titles stay in their original language; full articles are not republished.
