Ship a network that is built to last. Decentralised from day 1 — controlled by the community. Aztec's community launched the Ignition chain of Aztec on Ethereum main-net at 1am last night. The future is here and it is private.

There is a hidden elephant in the room for privacy chains. And no, it's not regulation. It's a far simpler question. How do you query for your balance, when everything is encrypted? Let's explore the elephant in the room when it comes to privacy chains. ↓🧶

◈ 7 Years ago, I created Aztec's original logo. It was a play on zero knowledge. An outer privacy shield wrapping secret data. Since then, @Zac_Aztec and I have poured everything into building programmable privacy. Today, our new brand reflects the scale of our ambition.

Ethereum storage proofs. Proved in a snark. In a web browser. It’s slow, but soon ™️ will be fast. You can use this to: prove ownership, solvency without revealing your wallets, voting preferences you name it. No more FTX’s. Private on chain voting. The sky is the limit.

1/3 Age verification online usually means giving up personal info, but it doesn’t have to. @ZKPassport uses zero-knowledge proofs to let users prove they're over a certain age without revealing their birthdate, name, or any personal data. aztec.network/blog/zkpasspor…

Remember Aztec Connect? It was really freaking cool – you could bridge privacy to any L1 DeFi protocol. However it was not without some issues... 🧶

Aztec is being created as a decentralised network. It's design, code, and operators are shaped by it's community. @aztecnetwork has launched an RFP for a key part of the network design - sequencer selection. Anon - will you answer the call?
