Too Long; Didn't Read
We will be walking through a simple zk-dapp for age verification, that will allow users to prove that they are below a certain age without revealing their actual age. This is a fairly trivial problem to solve and may not necessarily require zero-knowledge proofs but to keep things simple and easy to understand we will go ahead with this idea. The dapp will be using a nextjs app to interact with the smart contract and take user input ( age) which is meant to be private and will not be published on-chain. The proof generation occurs on the frontend using [snarkjs].
