What it does

Proof your content. Prove it’s human. Instant on-chain authenticity for files, built for teams.

Prove your media is human-made. Anchor cryptographic fingerprints on Solana, keep originals local, and hand teammates a proof they can trust in seconds.

We fingerprint within the browser. Your file never leaves your device. Paste the transaction ID, then upload the original file to confirm integrity. Secure your intellectual property with immutable blockchain timestamps. Files never leave your browser. Zero-knowledge privacy by design. Drag your file into the browser. We calculate a cryptographic fingerprint (hash) instantly. Your file data is never uploaded to any server. Sign the fingerprint with your private key. We then anchor this signature and timestamp onto the Solana blockchain forever. Share your transaction ID. Anyone can use our verifier to confirm you possessed that exact file at that exactfrom provefile.com

  • I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it.
