I created what may be the first self-authenticating jewelry design. This pendant was made parametrically, and the parameters are not reversible from its form. Only the owner will be given them. An Ed25519 public key can be used to verify parameter possession without disclosure.
Concretely, this setup enables the following verification behavior:
1. Alice owns this pendant and wants to prove to Bob it's authentic
2. Bob sends Alice a nonce
3. Alice derives the private key from her parameters and signs the nonce
4. Bob verifies the signature against the pendant's registered public key
presenting uniqueness at scale
True Snowflakes are 1-of-1 pendants, each a point in the parameter space of a formula modeling the radial symmetries of natural snowflakes and cathedral tracery
more always on the way; no duplicates, ever
honored to be a recipient of a new aesthetics grant from @patrickc & @tylercowen to explore how designing solely with code can change our relationship with the objects in our lives; my most ambitious projects coming soon
