**Nightfall\_4 (NF\_4)** uses a Zero-Knowledge Proof (ZKP)-based protocol for private transfers of ERC-standard tokens: * **ERC-20**: fungible tokens * **ERC-721**: NFTs * **ERC-1155**: multi-token standard * **ERC-3525**: semi-fungible tokens NF\_4 incorporates a **Layer-2 ZK-ZK rollup**, allowing transactions to be grouped into succinct proofs. Key properties: * **Scalable:** private transfers typically cost \~6,000 gas * **Fast finality:** finality is aligned with the underlying blockchain (EVM or SVM) * **Rust-based:** implementation written in Rust, while preserving NF\_3’s API for compatibility In order to run Nightfall you must run two applications: a `client` and a `proposer`. \ The purpose of the `proposer` is to make Layer 2 blocks. It makes an endpoint available to `clients`. Clients are the application that normal users will employ to make transactions that are hidden by ZKP. Full instructions for How to Run a Proposer on Plume Testnet can be found [here](https://github.com/EYBlockchain/nightfall_4_CE/blob/master/doc/Plume_Testnet_Docs/plume_testnet_proposer_playbook.md).\ \ `clients` are the application that normal users will employ to make transactions that are hidden by ZKP. the user can intitiate three types of transaction via the `client`: Deposit, Transfer, and Withdraw.
