Hi HN, We (myself, Adhyyan1252 and yush_g) are undergrad students that hacked out this side project last month during Hack Lodge[1] (the ideas and many of the underlying circuits for which came from the 0xPARC community[2])! We’re extremely excited to share this new primitive. Besides the technical challenges building this project that folks here would find interesting (fixing the ZK proof compiler, modifying nodeJS V8 params etc.), we think this is a very novel use case for ZK tech, and ECDSA inside ZK-SNARKs is a starting point that unlocks many other ideas! :D A summarized version of our…

Proof of Solvency (PoS) is a scheme designed to let users verify the solvency of online websites which accept Bitcoin (or other similar currency) deposits (e.g. exchange websites, online wallets, gambling websites, etc.) in a way that doesn't compromise the privacy of users. - olalonde/proof-of-solv

Hi! I made this as a hackathon project, the result is really cool and works very well. All you need to do is connect with your Metamask wallet and start creating documents. It also has proof of autorship, so we know if you wrote the document, or you just copy/pasted from chatgpt. This could be useful for schools or something. Let me know what you think. Thanks!

I've always been fascinated by cryptographic principles, so I decided to dive deep into zero-knowledge proofs and implement a Groth16 proof verifier entirely in Rust. This project validates cryptographic proofs and demonstrates how succinct, verifiable computations can be achieved. Using Rust's powerful libraries like arkworks, I implemented pairing checks, public input commitments, and proof validation logic while ensuring the code remains modular and efficient. I handled the complexities of affine group operations, scalar multiplications, and optimized public input verification to make…

I built AI Trust Proof — an experiment in recording human good faith on-chain so it can be independently verified by people, software, or (eventually) AI systems. What it does (today) - Lets you sign a plain-English pledge and record its signature hash + metadata on Solana (devnet). - Mints a symbolic NFT badge pointing to that record. - Creates a verification page that shows the pledge, signature, and on-chain proof. What it’s not - No token, no airdrops, no yield. - Not a reputation score or KYC. - Currently just one signal: "Pledge signed." Why - If AI systems begin prioritizing who to…
