Arc

⚠️ WARNING
Arc is currently alpha software and may contain bugs or unexpected behavior. Use at your own risk and exercise caution when sharing sensitive location data.

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.

Features

• End-to-End Encryption
  Messages are encrypted using a public key generated by a Distributed Key Generation (DKG) protocol, ensuring that only authorized recipients can decrypt the data.

• On-Chain Access Control
  Users can set on-chain conditions for access, such as:

  • Specific block time for access windows
  • Minimum token balance requirements
  • NFT ownership verification

  These conditions control who can decrypt and access the location data, creating a customizable privacy layer.

• Decentralized, Censorship-Resistant Messaging
  Arc uses the Waku network 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.

• Threshold Network’s TACO (Threshold Access Control)
  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.

Technical Overview

Arc combines a range of decentralized technologies to provide a secure, censorship-resistant communication system:

• Waku Network
  Arc utilizes Waku nodes for peer-to-peer message delivery, providing a resilient and censorship-resistant network for real-time location sharing.

• Threshold Network’s TACO
  Through TACO, Arc provides a secure and censorship-resistant method for encryption and access control, allowing users to define their own privacy parameters directly on-chain.
