# Introduction to Anubis privacy public chain

**Public chain name: Anubis**

**Total issuance: 21,000,000**

Anubis is committed to building a new privacy-oriented ZKRollup protocol to address the anonymity and confidentiality of smart contract data and logic. We focus on providing users with low gas fees, comprehensive smart contract privacy protection in the Ethereum ecosystem, and better support for the most commonly used assets, including ERC20, ERC721, and ERC1155, enabling them to be implemented in an EVM-compatible ecosystem. Better composability.

Technical implementation details: Anubis proposed an ABL model to develop confidential transactions under the DDH assumption using Twisted ElGamal encryption \[CMTA20] and Bulletproof range proof \[BBB+18]. In addition, the validity proof of batch transactions on the account Merkle tree is developed through algebraic compound non-interactive zero-knowledge proof. It is implemented in a two-layer architecture; the bottom layer is a ZKRollup, built on the R1CS constraint system, and translated into PLONKish Arithmetization \[GWC19], taking advantage of Twisted ElGamal encryption and hardware acceleration with custom gates. The application layer is an easily auditable encrypted transaction layer.

Anubis Design Philosophy: Anubis' goal is to provide every Web3 participant in the EVM-compliant ecosystem with a plug-and-play privacy-preserving application with the following features:

Low gas fees: Offers free deposits, batch transfers with ZKRollup, and low Gas withdrawals.

Composability: Supports Not only ERC20 but also ERC721 and exchanges. Privacy enhancement: Confidential transaction and address anonymity based on

ZKRollup. Easy to use: Based on self-hosted private key /mnemonic phrase management and multi-signature wallet based on account abstraction.

Ultimately, Anubis aims to provide users with a privacy “Lego” that protects the confidentiality and security of their assets before they enter other liquidity or protocols in the DeFi world.
