Advanced Concepts

In this section, you'll learn about the more advanced concepts of the Aztec Network. It is not required to understand these in order to start building on Aztec.

Aztec Overview

This page outlines Aztec's fundamental technical concepts. It is recommended to read this before diving into building on Aztec.

Circuits

Central to Aztec's operations are 'circuits' derived both from the core protocol and the developer-written Aztec.nr contracts.

Private Kernel Circuit

This circuit is executed by the user, on their own device. This is to ensure private inputs to the circuit remain private!

Public Kernel Circuit

This circuit is executed by a Sequencer, since only a Sequencer knows the current state of the public data tree at any time. A Sequencer might choose to delegate proof generation to the Prover pool.

Rollup Circuits

The primary purpose of the Rollup Circuits is to 'squish' all of the many thousands of transactions in a rollup into a single SNARK, which can then be efficiently and verified on Ethereum.

Storage

How are storage slots derived for public and private state

Wallet Architecture

This page talks about the architecture of a wallet in Aztec. Wallets expose to dapps an interface that allows them to act on behalf of the user, such as querying private state or sending transactions. Bear in mind that, as in Ethereum, wallets should require user confirmation whenever carrying out a potentially sensitive action requested by a dapp.
