Hey HackerNoon fam! We're excited to be rolling out zkWeb - a free and open-source web app that lets you prove you know something without spilling the beans about what that something is. Zero-Knowledge Proofs (ZKPs) just got a whole lot friendlier and, dare we say, fun! 🚀
Why You’ll Love zkWeb:
- So Easy, Your Cat Could Do It: We've made zkWeb super user-friendly. Whether you're a crypto-whiz or just crypto-curious, you're going to find it a breeze to use.
- Public API: Hey developers, we've got you covered! Integrate zkWeb's secret key validation features into your own projects.
- Open Source: zkWeb is totally free and open source. Come contribute to something amazing!
The Tech Behind the Curtain:
zkWeb is built on zokrates.js, a super-slick JavaScript implementation of the ZoKrates toolbox for zkSNARKs on Ethereum.
-
Proof Generation Wizardry - When a verifier submits a key (it could be a phrase, a date, even a small image file), zkWeb uses
sha256hashing to ultimately convert your key into a unique 14-digit hex string. This hex string is then fed to zokrates.js, which does some computational acrobatics using Solidity code to generate a unique cryptographic proof. It’s like making a secret recipe that only works with your specific ingredients. -
Proving the Key – The Secret Handshake: When a prover submits a key, zkWeb repeats the hashing hoopla, creating a new proof. This new proof is then compared with the verifier’s proof stored in zkWeb's database. If they match, voila! It’s a cryptographic high-five indicating a perfect match. If not, it’s a no-go. This means you can prove you know the secret without ever revealing it. Talk about a trust fall in digital form!
Take a look at the documentation for the full details on our technical implementation.
Test It Out:
See how the app works by entering Super secret key! on our demo proof page.
What's Next on the zkWeb Adventure:
We're not stopping here. zkWeb’s roadmap includes programmatic ZKP smart contract deployment to blockchains, and other exciting features. Stay tuned!
