# Overview

## What Nightfall does

Nightfall is an application that enables transfer of ERC20, ERC721 and ERC1155 tokens with privacy and scaleability. It uses Zero Knowledge Proofs to provide the privacy and an Optimistic Rollup to provide scaleability. It has a minimum transfer cost of 6500 Gas and a peak throughput of approximately 100 TPS.

Nightfall is intended for enterprise use and mainly for system to system interaction. It's not expected that it is used with a GUI, although it does provide a very simple one as a layer over its APIs for demonstration purposes.

Uniquely it makes use of x509 certificates for authorisation of users. These are available from several CAs so that decentralisation is not compromised: Just like everyday business interactions, Nightfall transactions are confidential but not anonymous.
