Introducing Aztec Tierra (Alpha V6).
The platform for unstoppable private apps is here.
Ethereum's only decentralized L2, with fully programmable privacy: permissionless, private smart contracts.
No backdoors. No gatekeepers.

CurveSmash is an open challenge to find new attacks on the elliptic curves securing Bitcoin and Ethereum.
Two new tracks just opened on BN254, the curve smart contracts use to verify SNARKs on-chain: discrete logs in GT, and pairing inversion. Read more below ⬇️
New on CurveSmash: two tracks on BN254 curvesma.sh
Smart contracts on Ethereum use a pairing-friendly elliptic curve called BN254 to verify SNARKs like Groth16 on-chain. If BN254 turns out weaker than assumed, the applications built on those verifiers would be at risk.
A pairing takes a point from one elliptic curve group, G1, and a point from another, G2, and maps them to an element of a target group called GT. That map is what makes BN254 useful for proofs. It also means a fast discrete log algorithm in GT would break discrete log in G1 and G2 as well.
The new tracks go straight at that structure. One asks for discrete logs in GT. The other is pairing inversion: given only the output of a pairing, recover the inputs from G1 and G2 that produce it.
Same format as the rest of CurveSmash. Bring your agents.
Nyx is live on Aztec Tierra with private ETH support and receiver addresses: give out an ordinary Ethereum address, get paid on it, and the funds land in your private account with no visible link between the two.

Another day, another impressive launch on Aztec Tierra.
Thanks to @xochi_fi, shielded settlement is live, and it settles straight into @zk_money.
Two apps built on Aztec working together, with the recipient and amount both hidden 🤝
Xochi.fi live with private, shielded settlement on @aztecnetwork V6, now via @zk_money!
Swap into zk.money for a private, Aztec-native experience.
We are always appreciative of the shoutouts from @VitalikButerin.
We even build out ideas of his, including RollingChat, a private message board designed by @Zac_Aztec, that is live on Aztec Tierra right now!

at Devcon 8 india 🇮🇳 Ethereum co founder @VitalikButerin gives a special shoutout mention to @aztecnetwork for being a noble and interesting L2
RollingChat is live: a private messaging board on Aztec Tierra.
Connect an Ethereum wallet, post under any name or as Anonymous. No wallet address is ever attached to a post.
Based on an experiment by @VitalikButerin, completed by @Zac_Aztec.

An unstoppable network depends on the people running it, in enough places that no one can switch it off.
The @aztecFND is putting 100M ethereum:0xa27ec0006e59f245217ff08cd52a7e8b169e62d2 behind sequencer operators, sized so staking yields remain attractive for everyone else.
Read more below to see who can apply.
A platform for unstoppable private apps should have powerful, bold branding.
Presenting our brand refresh: an updated look across aztec.network and everywhere else, built around one mission: being the platform for unstoppable private apps.

V6 Partner @nulo_sh is THE wallet for Aztec, now live on Chrome and Firefox.
Free, open source, and shows you the privacy status of each send before you confirm.
Plus, for the first time, you can use Shield by @humntech to bridge both ETH and USDC into Aztec from Ethereum!
Nulo is live.
Now on the Chrome Web Store and Firefox Add-ons. Private by default, public when you say so.
Free and open source.

Coverage thread of the Aztec Tierra launch, starting with @l2beat.
L2BEAT continues to certify Aztec Tierra as a Stage 2 rollup, meaning it's immutable, permissionless, and private!
More coverage below ⬇️
Aztec v6 is not only about ancient civilizations or wild and free-running horses, but also the first version of @aztecnetwork with no known vulnerabilities!
In the meantime, while fixing the proof system, they streamlined their decentralised governance process, accelerated proofs, and had their first private apps launched (including @zk_money which we already track).
The latest ZK rollup is as immutable, permissionless, private and Stage 2 as the previous ones, a refreshing new normal. Because privacy is normal.

In practice, programmable privacy means a bank could build viewing keys into its own app for compliance purposes, while the network underneath the app holds none.
That split is how Aztec Tierra works, and @Zac_Aztec explains on @Bankless why institutions need it.

NEW EPISODE - The Race to Build the Private Ethereum
Can Ethereum have truly private smart contracts without backdoors?
Aztec co-founder @Zac_Aztec joins @TrustlessState to make the case for privacy without privileged access, and why he believes @aztecnetwork stands apart from competing networks.
They break down why Wall Street needs privacy to move onchain, how ZK Passport enables identity verification without exposing personal data, and why AI-powered cyberattacks could make decentralized infrastructure more important than ever.

If you're headed to @EFDevcon this week, mark these events down! Our co-founder @Zac_Aztec is speaking at multiple events across a variety of privacy-oriented topics. 🧵👇
First, catch Zac @IBWofficial mainstage on November 2, discussing onchain finance! xitter.twitterapi.xyz/IBWofficial/status/211…
Zac Williamson (@Zac_Aztec) joins IBW2026 as a speaker.
Co-Founder & CEO of @aztecnetwork, the privacy Layer-2 on Ethereum. Doctorate in particle physics from Oxford. Co-author of PLONK, the 2019 SNARK paper now used widely across crypto.
1-2 November. Mumbai.
Later on November 2, Zac will be at the Cypherpunk Congress event in Mumbai, discussing Post Quantum Cryptography with @jbaylina.
More info here: xitter.twitterapi.xyz/web3privacy/status/211…
Post-Quantum cryptography is challenged by rapid AI developments.
@matthew_d_green claims "there is a 1% chance we live in Minicrypt, and a 15% chance we functionally lose confidence in our existing public-key encryption algorithms."
@drakefjustin invites people to the bunker mode.
@Zac_Aztec "without post-quantum public-key cryptography, we are all a little bit *screwed*".
Take a deep breath. Calm down. Let experienced cryptographers do the talking.
Welcome, @Zac_Aztec x @aztec & @jbaylina x @ziskvm - encryption heavyweights who will do a fireside on the state of cryptography, AI threats, PQC and more.
At Cypherpunk Congress in Mumbai: congress.web3privacy.info
Share an address once, and anyone can watch what it does afterward.
@nyxmoney receivers let you hand out a different Ethereum address each time, with no visible link between any of them and your private account.
Launching soon on Aztec Alpha V6.
Receivers are coming soon to Nyx v6 on @aztecnetwork v6! To start, you can create up to 5 receiver addresses on Ethereum that forward to your private account.
Private apps need a stable foundation.
Noir 1.0 is that foundation: the language behind Aztec’s private smart contracts and protocol circuits, now audited, fuzzed, and production-ready.
Next up: Aztec Alpha V6.
Noir 1.0 is live.
A more reliable foundation for zero-knowledge applications: stable language, versioned toolchain, audited compiler.
Developers can build and iterate predictably as they create the next wave of privacy-preserving apps.

"Privacy" is a crowded word now.
Zac co-wrote PLONK in 2019, before many of the projects using that word today existed.
Aztec has been building the same thing ever since: programmable privacy made accessible for everyone.
V6 Launch partner @nulo_sh is the wallet Aztec developers have been asking for.
Clean, fast, and built so any app can connect and start shipping private features.
Users pick what each app sees and approve every send. Free, open source, and live at launch.
You're on camera. You choose what it sees.
Meet Nulo, a wallet for @aztecnetwork. Private by default, public when you say so.
On Chrome and Firefox stores in early November. Free and open source.
Your NFT wallet is a public profile you never agreed to publish.
@ravenhousenft lets you collect, bid and prove community membership without sharing any information you don't want to.
Two years in the making, and officially arriving with Aztec V6 as a launch partner.
