Subject: Initial commit: OnionCoin prototype with Proof-of-Relay consensus

OnionCoin is a privacy cryptocurrency that rewards Tor relay operators
through a unique Proof-of-Contribution consensus mechanism.

Core Features:
- Proof-of-Relay: 30% of block rewards go to Tor operators
- Native .onion node identity (no IP exposure)
- Temporal obfuscation protocols
- Dandelion++ over Tor propagation
- Native inheritance system with dead man's switch

Technical Stack:
- Rust workspace with 8 crates
- Ed25519/X25519 cryptography
- arti (Rust Tor client) integration planned
- 10 minute block time, 5-10 TPS design

Status: Prototype
- Consensus logic complete with passing tests (30/33)
- Network layer conceptual design complete
- Tor integration pending
- Testnet launch planned Q3 2026
