UmbraVOX

UmbraVOX is a decentralized communications research project focused on censorship-resistant, privacy-preserving messaging. The project combines protocol design, technical specification, and a reference implementation.

Key Design Properties

• End-to-end confidentiality using Signal Double Ratchet with ML-KEM-768 post-quantum layer
• Fully decentralized architecture with no central servers
• 11-day automatic chain truncation for message ephemeralness
• Deniable design with no asymmetric payload signatures
• Dandelion++ propagation for sender obfuscation
• Token-based spam resistance via Universe Cycle economic model

Architecture

• Dual-mode messaging: On-chain broadcast (370-530ms latency) and direct P2P (50-150ms latency)
• Consensus: Ouroboros Praos with ~80.8 messages/sec global throughput
• Block size: ~4.55MB with 4,444 messages per block
• Core: Pure Haskell with constant-time C FFI for cryptographic operations

Status

UmbraVOX is currently in the design and specification phase. No production release is available.
