Holonym · interactive mechanism simulation

A user proves a credential (govID / passport / phone) off-chain, generates a zero-knowledge proof client-side, and the proof's nullifier is checked so each real-world ID can mint only one soulbound token per action. Unique humans get an SBT; replayed credentials get rejected. Edit the parameters and watch the identity flywheel change.

Illustrative simulation. Reflects the researched Holonym/Zeronym design — off-chain credential check, client-side ZK proof, one-nullifier-per-action-ID uniqueness, and a soulbound ERC-721 on Optimism — but submission volume, timing, and the sybil-share slider are simplified for visualization, not live onchain data.
