Implements comprehensive privacy primitives for confidential transactions:
- synor-privacy crate:
- Pedersen commitments for hidden amounts with homomorphic properties
- Simplified range proofs (bit-wise) for value validity
- Stealth addresses with ViewKey/SpendKey for receiver privacy
- LSAG ring signatures for sender anonymity
- Key images for double-spend prevention
- Confidential transaction type combining all primitives
- contracts/confidential-token:
- WASM smart contract for privacy-preserving tokens
- UTXO-based model (similar to Monero/Zcash)
- Methods: mint, transfer, burn with ring signature verification
42 passing tests, 45KB WASM output.
