Aztec Enters New Phase of its Public Testnet: Introducing the Adversarial Testnet

We're now entering a new phase: the Adversarial Testnet. This stage will test the resilience of the Aztec Testnet and its decentralization mechanisms. The Adversarial Testnet introduces two key features: slashing, which penalizes validators for malicious or negligent behavior in Proof-of-Stake (PoS) networks, and a fully decentralized governance mechanism for protocol upgrades.

Testnet Retro - A Case of Divergent Mempools

On May 29th, 2025, the Aztec Labs team observed a sharp slowdown in block production starting around 1:30 PM UTC. An emergency update was shipped and adopted by node operators, which resolved the issue and restored the network to full capacity. In this blog, we break down what went wrong and how we fixed it.

StealthNote: The Decentralized, Private Glassdoor of Web3

Comparative to Glassdoor, StealthNote is an app that allows users to post messages privately while proving they belong to a specific organization. Built with Noir, an open-source programming language for writing ZK programs, StealthNote utilizes ZKPs to prove ownership of a company email address, without revealing the particular email or other personal information.

A New Era for Web3: Introducing Aztec Public Testnet

Earlier this month, we announced the successful testing of the first decentralized upgrade process for an L2, with over 100 sequencers participating. Now, with the mission to bring programmable privacy to the masses, the Aztec Public Testnet is here and, for the first time ever, open to developers to build fully private applications on Ethereum.

The Best of Both Worlds: How Aztec Blends Private and Public State

In this article, we’ll talk about one of the core components unlocking privacy on Ethereum: state management. We’ll shed some light on programmable and composable privacy which allows dApp developers to choose what they want to make private and what to leave public. That allows for an ecosystem of privacy-preserving dApps that can communicate with each other as well as Ethereum.

Security of the Aztec Network: Audits of Bigfield

We are constantly striving to make the Aztec Network more secure by developing internal tooling and seeking external expertise. ‍To prepare for a barrage of future audits before the mainnet launch, we ran a test exercise with three well-established auditing companies including ZKSecurity, Zellic, and Spearbit.

Road to Mainnet

Since Aztec's launch seven years ago, we’ve been on a mission to solve one of the biggest barriers to mass blockchain adoption – privacy. Imagine a world where developers can write programs that protect user data but take full advantage of a trustless, permissionless system – all backed by the security. This is what we’re working towards, and this product roadmap is how we get there.

Unlocking the Future of Privacy: Exploring Identity and Social Use Cases in Alpha Build 2 with $100k in Prizes

After 7 years of building in the open, last month we announced that Devnet is now live. To celebrate we launched Alpha Build, a series of three developer sprints with up to US$100,000 in prizes and the opportunity to deploy on the Aztec for the first time. Starting October 8th - October 29th, 2024, the second sprint, Alpha Build 2 (AB2), will focus on identity and social.

WTF is Aztec?

Blockchains like Bitcoin and Ethereum provide humanity with programmable digital money. Aztec is a privacy-first Layer 2 on Ethereum. It enables a critical dimension of programmable digital money that has heretofore been ignored: privacy.
