The secret weapon for lightning-fast authentication with Aztec is the ingeniously optimized ecdsa verification in barretenberg. This isn't a theoretical optimization: we're talking <1s proving time & 30ms verification. Lets do a deep dive 🧵 (Source: https://t.co/W5KzSzReo6)
Aztec can do exactly this. All of it. I’m so happy. I can’t stress how exactly Aztec can do this. Fast client-side proving on desktop and mobile, well under 1GB RAM. Native, private account abstraction is already built into Aztec. Think of a way to authenticate a user… Eth

token 2022 passed six audits, used one of the simpler and more conservative zk systems - bulletproofs for confidential transactions. And still had a fatal money printing zk bug. Moreover, a "not including all inputs in Fiat Shamir" bug, you'd think people would know to look for.

Alice and Bob on a Date (at ZkSummit) Alice: Aren't you tired of sharing secrets in the same secure channels? Bob: Yeh, it's getting dull. Don't tell anyone, but sometimes I forget the secrets just to keep it fun 🤫 Alice: Stop it, you are crazy. Bob, what is your dream? Bob:
Today we're announcing Aztec Sandbox, a local developer testnet for smart contract privacy. Aztec Sandbox is the most ambitious software release in Aztec Labs history and the first major step toward Aztec's endgame: A fully decentralized, privacy-preserving Layer 2.
