One-of-a-kind privacy-focused rollup that effectively combines the concepts of Optimistic Rollups with Zero-Knowledge (zk) cryptography thus creating a private and scalable transactions solution
Optimistic Rollups with Zero-Knowledge
Nightfall 3 is an upgraded version of Nightfall aimed to lower the transaction cost of ERC20, ERC721 and ERC1155 token private transfers. It uses Optimistic Rollup for lowering the costs and the privacy is attained by leveraging zero knowledge proofs. The optimistic rollup contracts are deployed on Ethereum (layer 1). Validators will roll up transactions into blocks and submit them to the Optimistic contracts. Challengers will submit fraud proofs for any invalid block to the same contracts. All the information required to perform a private transfer exists with clients and does not rely on any off chain third party.
Enables token transfers of ERC20, ERC721 and ERC1155
Rooted in the security of Ethereum
Lower transaction costs due to optimistic approach
Provides higher throughput
Full ownership and control of assets
Non-custodial architecture
Incentivised LPs that provide instant withdrawal of fungible tokens could also provide the minimum one honest verifier requirement
In public domain and community driven
Provides SDK for development
Provides CLI and web wallet (through Polygon website) interfaces
Layer 2 scalability solution
Implementing Polygon Nightfall results in below numbers.
9000 - GAS per transaction
110 txn/sec - Throughput
