Orchard Shielded Assets
summary
Proposal implements issuer key + 512‑byte description to derive an asset type (hash-to-curve), adds per‑type value base point for homomorphic value commitments, and keeps transfers fully shielded and backward compatible with Orchard. Issuance is transparent issuance (supply tracked on-chain), multiple assets can be issued and airdropped in one transaction, and burning uses the existing value-balance field. Prototype lives in a forked Orchard crate with tests for the binding signature, ~$1M grant and two milestones completed.
