Use at your own risk and exercise caution when sharing sensitive location data.\n\n\n**Arc** is an experimental, privacy-preserving, permissionless, decentralized location-sharing application. Arc enables secure, end-to-end encrypted location sharing with fine-grained, on-chain access control, making it a powerful tool for individuals or groups needing private, censorship-resistant communication and location sharing.\n\n## Features\n\n- **End-to-End Encryption**  \n  Messages are encrypted using a public key generated by a Distributed Key Generation (DKG) protocol, ensuring that only authorized recipients can decrypt the data.\n\n- **On-Chain Access Control**  \n  Users can set on-chain conditions for access, such as:\n  - Specific block time for access windows\n  - Minimum token balance requirements\n  - NFT ownership verification\n\n  These conditions control who can decrypt and access the location data, creating a customizable privacy layer.\n\n- **Decentralized, Censorship-Resistant Messaging**  \n  Arc uses the [Waku network](https://waku.org/) for peer-to-peer message delivery, enabling secure and private data sharing without reliance on centralized servers. Waku’s decentralized framework ensures censorship resistance by allowing messages to propagate across nodes without a central authority, making it difficult for any single entity to restrict communication.\n\n- **Threshold Network’s [TACO](https://threshold.network/) (Threshold Access Control)**  \n  Arc integrates TACO for end-to-end encryption and access control, enabling users to encrypt location data and control access permissions directly on-chain. By operating on a decentralized network, TACO enhances censorship resistance, preventing any authority from blocking or tampering with data access.\n\n## Technical Overview\n\nArc combines a range of decentralized technologies to provide a secure, censorship-resistant communication system:\n\n- **Waku Network**  \n  Arc utilizes [Waku](https://waku.org/) nodes for peer-to-peer message delivery, providing a resilient and censorship-resistant network for real-time location sharing.\n\n- **Threshold Network’s TACO**  \n  Through [TACO](https://threshold.network/), Arc provides a secure and censorship-resistant method for encryption and access control, allowing users to define their own privacy parameters directly on-chain.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnucypher%2Farc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnucypher%2Farc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnucypher%2Farc/lists"}
