NOCBY - zkp steganography data privacy data security

by
A real-world hack challenge built on ZKP + steganography. Even with 800+ attempts, no one cracked the data. VOID proves how data can be fully visible yet 100% unreadable. #noonecanbeyou

Welcome friends 👋 This project was built to test the limits of privacy, steganography, and proof systems. Every visual you see hides a secret. Will you be the first to crack it? What inspired us? Life is full of experiences. In one of our projects, we had a client who was obsessed with the color red. He wanted everything to be red. His logo was red, and he insisted that we place it on a red background that matched the logo's tone exactly. We tried to explain that it wasn’t a logical design choice, but he wouldn’t budge. In the end, we said, “Well, the boss is the boss,” and did exactly what he wanted. We placed the logo over the red background, and when he saw the final result, he told us we had forgotten to include the logo. We then explained to him that the logo was actually there, but because it was the exact same red, it was invisible. We even showed him in the code. This moment actually became one of the inspirations behind the Devdeed Void Algorithm. Sometimes, it’s all about thinking simply. If the color of something matches the background exactly (like in the image above), no matter what you write or place on it, no one can see it—even though it’s right in front of them.

@omer_faruk_bulut2 Using zkp and steganography together is a very creative view, congratulations

🕵️‍♂️ Mind = Blown. NOCBY isn’t just a secure chat — it’s a puzzle, a challenge, and a statement about visibility in the digital age. The story behind the Void Algorithm is genius: what you can’t see might just be hiding in plain sight. Can you crack the code? 🔍✨

Super interesting approach combining ZKP with steganography really interesting take on privacy and data security it looks very promising.

Proud to be hunting this gem today! From the moment I discovered this product, I knew it had something special. It’s smart, it’s timely, and it solves a problem we all relate to. Hats off to the maker for bringing this to life. Let’s blow this up, Product Hunt fam — drop your upvotes and show some love!

Just checked out NOCBY really cool concept usage of ZKPs and steganography together is interesting. Definitely keeping an eye on this one!

Loving the clean UI and straightforward approach — productivity tools should all be this intuitive.

Best use of zero-knowledge principles in a public art form I’ve seen. Forces you to question what’s visible vs. what’s provable. You don’t just view it you audit it.

Mind-blowing use of visual steganography. The invisible logo story is the perfect metaphor simple, clever, and unsettling. Devdeed Void Algorithm is elegant in concept and ruthless in execution.

Interesting! Not easy to grasp at first, but definitely makes me curious!

Shreyans Bhansali

Wild concept—love the mix of storytelling and tech here. Curious though, how do you validate the proofs without compromising the hidden layer? Is it zero-knowledge or something custom?

Ömer Faruk BULUT

Hey Shreyans, really good question!

It's a custom method inspired by zero-knowledge principles. Instead of verifying by revealing the data, we verify based on pattern integrity. The proof remains unreadable without the owner's decoder — but its structure still allows validation.

If you're curious to dive deeper, we’d love to invite you to our ongoing challenge on Discord. You’ll find more details about the product, the algorithms, and how it all works in the channels there:
