Aztec Tierra V6 doubles private proof speed and fixes V5 flaw

Aztec’s privacy-focused Ethereum Layer 2 announced its Tierra Alpha V6 upgrade on November 3, saying it fixes security issues in earlier versions and makes private transactions faster.

Faster proofs and Ethereum-to-Aztec messages could reduce the wait for users moving funds into private applications.

In its Tierra announcement, the Aztec Foundation said the release resolves vulnerabilities from earlier versions, including a critical issue discovered in V5. Aztec’s network status page lists Tierra as version 6.0.0 and says the V5 vulnerability was resolved with its release. The Block also reported the upgrade, citing the Foundation’s performance figures and security changes.

What did Tierra V6 change in the network?

The upgrade includes security fixes, an AI-powered security testing harness and formal verification of core cryptographic components, according to the Foundation. Aztec did not detail the scope of the verification in its announcement. The Block reported that an Aztec spokesperson said the V5 fix required the whole network to move to a new version because there is no central operator able to make the change alone.

Aztec’s status page describes V6 as an Alpha network release and says the critical V5 finding is resolved. That places the patch in the context of an early network version: the release addresses the reported issue, while the status page continues to label the network Alpha.

How does the upgrade speed up private transactions?

The Foundation says private transaction proofs now take one second on a native device, twice as fast as on the previous network. Aztec’s architecture lets private functions execute and generate proofs on a user’s device, while public functions execute on the network, according to the Foundation.

Tierra also changes Ethereum-to-Aztec message delivery. The Foundation says messages that previously took an average of two minutes can now arrive in as little as 12 seconds. The Block reported that this speeds up deposits and other transactions between the networks. The announced figures describe a minimum message time and an average before the upgrade, not a guaranteed delivery time for every message.

Which apps are launching alongside the upgrade?

The Foundation says Tierra arrives alongside applications launching or preparing deployments across payments, trading, AI and social use. Its list includes zk.money for private payments and savings, Nyx for private payments to Ethereum wallets, Galactica for private AI inference, and Nemi for private perpetuals trading.

Aztec says users can deposit from an Ethereum wallet directly into zk.money using the faster messaging system. The upgrade therefore links the infrastructure change to a specific app use: moving funds from Ethereum into a private payments service with less message-delivery time. The Foundation also named Nulo, Xochi, Olla and Rolling Chat among the applications launching or preparing deployments.
