Aztec is a Layer 2 solution that allows on-chain transactions to be more private and cost-effective, maintaining decentralization and security while keeping some information private.

👥 has secured $119.1 million in funding including: a16z, HashKey Capital, Fenbushi Capital, Variant Fund, SV Angel, Alumni Ventures, King River Capital

Understand the Aztec core module in one second.
▪️PXE: Mainly through the client, it generates zk-proof to prove that I did something and then sends it to the chain, protecting some keys, notes, and other data while also generating a sample.

▪️AVM: Executed by sequencer nodes, similar to the EVM on Ethereum, it is independent from PXE, and they do not communicate with each other, so private content in PXE will be prioritized.

▪️ZK-rollup: Private + Public state update → rollup proof → Submit for Ethereum verification

▪️Account abstraction: Abstract wallets have now become synonymous with security, and each account will be a smart contract.

▪️Private and public state：
Private states work with UTXO, which is mainly used to maintain privacy by storing notes in the UTXO tree. When a note becomes invalid or is deleted, a nullifier is generated and the Nullifier exists in its own Nullifier tree.

Public state and Public Ledger are similar in that they store public data in a public data tree.

👀 In Aztec, abstract wallet addresses are encrypted, allowing you to set who can see your account and who cannot.

The settings can be split in more detail, such as one's own trading, income, and transfer information, which can be extracted separately for encryption.

Nodes can buy servers to run, or they can run locally. If using Windows, WSL can be used, and you can take the IP and address to obtain identity in DC.
