Zk knowledge is a fundamental aspect of Web3 as it is heavy on cryptography and privacy concerns. Holonym is one of the protocols that embrace zk knowledge in administering its infrastructures. The users can use Holonym to vote anonymously without exposing their precise details. Unlike most cases when users lose access to their wallets when they lose their keys, Holonym leverages zk proofs for the users to prove they are the owner of their wallets even without their private keys. On the other hand, projects can also leverage Holonym to airdrop to their users without bothering about KYC and other regulatory impediments.
