Welcome to Alice's Ring, an open-source, community-driven initiative aimed at enhancing privacy in the Web3 ecosystem through the use of Ring Signatures. Our goal is to make privacy a core aspect of digital interactions, empowering developers to seamlessly integrate ring signature-based privacy features into decentralized applications.
Alice’s Ring is a suite of cryptographic tools designed to empower developers to integrate privacy into blockchain applications using Ring Signatures. By supporting multiple languages and platforms, Alice’s Ring provides flexible, cross-environment solutions—from front-end TypeScript libraries to on-chain verifications in Solidity, and high-performance implementations in Rust.
Our mission is to shape a future where privacy is embedded in every layer of the Web3 experience, offering users secure and anonymous solutions.
- TypeScript: Libraries for front-end development, enabling privacy-preserving interactions with decentralized applications.
- Rust: High-performance library for ring signature verification, ideal for privacy-preserving applications requiring enhanced security.
- Solidity: On-chain verification tools for Ethereum, bringing privacy features directly to smart contracts.
- Cairo: Tools for StarkNet, allowing developers to use ring signatures in Ethereum's Layer-2 solutions.
Ring Signatures are cryptographic protocols that enable a group of users to sign a message while preserving the anonymity of the actual signer. Unlike traditional digital signatures, ring signatures introduce signer ambiguity, making it unclear which member of the group produced the signature. This ensures that the message could plausibly have been signed by any participant, making it extremely difficult to trace the true author.
Ring signatures enhance privacy by making transactions untraceable. They are widely used in applications such as blockchain-based privacy coins (e.g., Monero) and secure voting systems, where anonymity and security are paramount.
SAG signatures allow spontaneous group formation, ensuring anonymity without requiring setup among members.
LSAG adds linkability to SAG, making it useful for blockchain environments to prevent double-spending while maintaining privacy.
The Alice's Ring monorepo includes several projects, each focusing on different implementations and integrations of ring signature schemes:
- SAG-ts: Audited TypeScript implementation of Spontaneous Anonymous Group (SAG) signatures. Useful for front-end developers integrating SAG-based privacy features.
- LSAG-ts: TypeScript implementation of Linkable Spontaneous Anonymous Group (LSAG) signatures. Extends SAG for privacy with linkability to prevent double-spending.
- Metamask-snap: A MetaMask Snap that allows users to generate and verify ring signatures directly from their MetaMask wallet.
- ring-sig-utils: A collection of utility functions supporting ring signature operations across various implementations.
- Rust verifier: A high-performance verifier for SAG and LSAG signatures written in Rust. It provides a robust solution for secure, privacy-preserving applications.
- SAG EVM verifier: An Ethereum-compatible (Solidity) verifier for SAG signatures, enabling on-chain privacy features in smart contracts.
- Documentation: Comprehensive guides, tutorials, and references for each of the above libraries and implementations.
Cypher Lab is dedicated to making privacy a foundational pillar of the Web3 ecosystem. We believe that privacy is critical to decentralization and that users should have control over their data and identities. Our focus is on building privacy-preserving cryptographic tools that empower developers and users.
Our key projects include:
- Alice's Ring: A suite of libraries implementing ring signatures to ensure privacy in blockchain transactions.
- Privacy Protocols: We design and develop cryptographic protocols that prioritize user privacy, security, and decentralized control.
