    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 was learning ZK proofs and found that visualizing things really helped me understand them. Noticed there aren't many interactive visualizations out there, so I built one. Here's the first version: zkvisualizer.com It walks through the full pipeline step by step (Problem → Circuit → R1CS → Polynomials → Witness → Proof → Verification) with real Groth16 proofs generated in your browser using snarkjs. You can toggle between what the prover knows vs what the verifier sees, and there's a tamper detection demo where you can watch verification fail. This is still very early on, but I would be…

    Most ZK proving systems are optimized for server-grade hardware with massive RAM. When scaling to industrial-sized traces (2^20+ rows), they often hit a "Memory Wall" where allocation and data movement become a larger bottleneck than the actual computation. I have been developing Hekate, a ZK engine written in Rust that utilizes a Zero-Copy streaming model and a hybrid tiled evaluator. To test its limits, I ran a head-to-head benchmark against Binius64 on an Apple M3 Max laptop using Keccak-256. The results highlight a significant architectural divergence: At 2^15 rows: Binius64 is faster…

    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…

    hey folks! My book Real-World Cryptography was just released and is now shipping. I've been working on this thing for the last two years and a half, and the goal was to give a good overview of everything that can be classified as "real-world" about crypto. You'll find all the basics in the first half of the book, and the second half contains chapters on TLS, noise, PAKEs, post-quantum cryptography, zero-knowledge proofs, MPC, cryptocurrencies, FHE, etc. So it's a good pick if you're learning, but also if you've been in the field for a while and want an intro to some subfield you're…
