README
AZTEC is an efficient zero-knowledge privacy protocol. The protocol powers real world financial applications on Ethereum mainnet today. A complete explanation of AZTEC can be found in our white paper.

## FAQ :question:
### What is the AZTEC Protocol?
The protocol enables transactions of value, where the _values_ of the transaction are encrypted. The AZTEC protocol smart contract validator, `AZTEC.sol`, validates a unique zero-knowledge proof that determines the legitimacy of a transaction via a combination of **homomorphic encryption** and **range proofs**.
### What is encrypted 'value'?
Instead of balances, the protocol uses AZTEC **notes**. A note encrypts a number that represents a value (for example a number of ERC-20 tokens). Each note has an owner, defined via an Ethereum address. In order to _spend_ a note the owner must provide a valid ECDSA signature attesting to this.
### What does this enable?
#### Confidential representations of ERC20-tokens
The AZTEC protocol can enable confidential transactions for _any_ generic digital asset on Ethereum, including _existing_ assets. Our [first deployed asset](https://etherscan.io/address/0xc5c0B2E7a265c96D29aE1E4e70Cd542deDc87aee) enables zkDai.
#### Fully confidential digital assets
The AZTEC protocol can be utilized as a stand-alone confidential token, with value transfers described entirely through AZTEC **join-split** transactions
### How much gas do these transactions cost?
The gas costs scale with the number of input and output notes in a **join-split** transaction. For a fully confidential transfer, with 2 input notes and 2 output notes, the gas cost is approximately 300,000 gas.
### Where can I see this in action?
The AZTEC protocol is [live today on the Ethereum main-net](https://twitter.com/aztecprotocol/status/1225152974596530187). [Here is an example AZTEC join-split transaction](https://etherscan.io/tx/0x8c35f5e081716a4cf9b5e71071403036dd4bf771360a146e4d6465fa4e24bd69).
### Range proofs you say? How does that work?
Read the AZTEC paper [here](https://github.com/AztecProtocol/AZTEC/blob/master/AZTEC.pdf). The unique AZTEC commitment function enables the efficient construction and verification of range proofs. The protocol requires a trusted setup protocol, that generates a dataset that is required to construct AZTEC zero-knowledge proofs
#### The Trusted Setup
AZTEC ran Ignition, an MPC ceremony to generate a CRS for our privacy network and other zero-knowledge systems like PLONK from October 25th 2019 to the January 2nd 2020. 176 individuals and institutions took part, each generating randomness and adding it to the previous participant's contribution. If even one participant acts honestly and destroys the randomness they generated, the CRS can be trusted. You can see a recap of Ignition [here](https://medium.com/aztec-protocol/aztec-crs-the-biggest-mpc-setup-in-history-has-successfully-finished-74c6909cd0c4).
### Are AZTEC transactions anonymous as well as confidential?
The AZTEC protocol currently only supports confidentiality of amounts. We will be adding User privacy and Code privacy to the protocol and SDK.
