About Nightfall 3
Nightfall_3 is an open-source repository containing an optimistic version of Nightfall, an application for transferring ERC20, ERC721 and ERC1155 tokens under zero-knowledge proofs. It is designed to handle the zero-knowledge proof artefacts itself and to expose a simple token-transfer API. According to the repository, when used correctly it hides the recipient and the transferred token.
The project uses optimistic rollups to reduce gas costs. The repository states that under the right conditions a zero-knowledge transfer can complete for approximately 6500 gas, compared with 700 kGas for the original Nightfall application. It describes itself as a Layer 2 solution with on-chain data availability, and states that it maintains the security and consensus assumptions of Ethereum Mainnet. The repository says it is intended as an enterprise application. In its basic form it has no graphical interface and is meant to be integrated into an ERP or similar system through its APIs. Running it locally requires Docker, Node.js and npm, and the repository says Windows is not supported. The code is provided by EY with no warranty, on an as-is basis.
Key features
- Zero-knowledge transfers of ERC20, ERC721 and ERC1155 tokens
- Simple token-transfer API that abstracts zero-knowledge proof artefacts
- Optimistic rollup design on a Layer 2 with on-chain data availability
- Decentralised access control
- Docker-based local test setup using Ganache as a blockchain simulator
Best for: Enterprise development teams that plan to add private token transfers to an ERP or similar system through its APIs.
Good for
- Exposes a token-transfer API so developers do not need to work directly with zero-knowledge proof artefacts
- Repository reports a gas figure of approximately 6500 for a transfer under the right conditions, versus 700 kGas for the original Nightfall
- Repository describes decentralised access control as a feature
Watch out for
- Basic form has no graphical user interface
- Windows is not supported according to the repository
- Repository describes the application as fairly complex and says it requires time to understand, and provides no warranty
