smart contracts, front-end, and discord bot for a zero knowledge verification service
Check out the Demo: https://www.zknft.one/ (must have Metamask extension and Zk-keeper-plugin extension)
Add our Discord bot to your channel to start verifying users with NFTs! https://discord.com/api/oauth2/authorize?client_id=951330025699934259&permissions=534992387136&scope=bot
How it works: You stake your NFT in the ZK-NFT contract. The contract will add you to a whitelist. In the contract, a commitment is added to an Incremental Binary Tree which can be verified via Circom based on the Groth16 protocol.
Then, you can generate a proof (a cryptographic string) using our frontend. You can think of the proof as a one-time-use password which can be used in any situation (proving you own an NFT, voting anonymously for a DAO, or entering a Bufficorn party!) In our demo, we show you how to access private channels in Discord!
Inspiration: Collab.land had a vulnerability where people were proving they owned NFTs without anonymity. People were hacked because they interacted Discord with their private wallet! The solution is to limit Discord's from directly interacting with wallets
For EthDenver Virtual 3/21/2022
- Nullifier (One time use unstake NFT upon use)
- Generate proof with pure frontend (waiting for Semaphore team to fix zk-keeper chrome extension)
