This ERC extends ERC-721 with interoperable commitments to private NFT-to-NFT references. A token can publish one or more reference commitments without disclosing the referenced NFT, reference label, weight, or authorization material. Implementations expose a common discovery interface, may require a zero-knowledge or other privacy-preserving proof at mint time, and may support later selective disclosure of individual references.
The core interface is proof-system-neutral. It does not require Groth16, a particular elliptic curve, Poseidon, a fixed number of references, or a specific authorization registry. Optional extensions standardize proof-gated minting, selective reveal, registration-snapshot owner authorization, canonical public policies, and rank-governed DAG insertion.
