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…

Hi HN, I'm releasing my round one public demo of a new browser security system I've been developing. There's a real Bitcoin private key (worth $20) in plaintext at app.redactsure.com. You can copy it, paste it, delete it, move it around - full control. But you can't see the actual characters or extract them. The challenge: Break the protection and take the Bitcoin. First person wins, challenge ends. Details: - Requires email verification (prevents abuse, no account needed) - 15 minute time limit per session - Currently US only for the demo (latency) - Verify the Bitcoin is real:…

wsgrok▲7I built it for myself because ngrok didn't let me add one more domain unless I paid $12 more. I probably should've looked for alternatives before building my own, but my grudge got in the way . Once I started, I wanted to make it better than the other options. Silly, I know. No one probably cares. I plan to open source it sometime next year because I’ve got other projects to finish first. It's free until I deplete my cloud credits, then it will switch to a tier-based model with a free option.

We've set up DeekSeek R1 with a system prompt that attempts to censor the word PRIVATEKEY from its response. If you can get DeepSeek R1 to output that string (not in the reasoning, but in the final response), the system will reveal a private key which contains $1000 USDC. You will have a 50 token limit in the input. We will have a series of contests, sponsored by AI researchers, in order to learn more about prompt engineering and how LLMs interact with real money. Good luck! Edit: The money was claimed! Thanks for playing all. You can still play for fun. Stay tuned for the next one! Stats:…

Finding the balance between humans and machines has been the thread through my career. I always had a thing for AI and couldn't wait for it to actually deliver on what was promised. Now it does, and it's more important than ever that humans and machines keep working well together. AI makes creation trivial. Text, code, design, strategy, in seconds. But one thing AI does not create: independently verifiable proof of when something existed. Reproducing is now cheaper and easier than creating. Chronology becomes contestable at the moment it matters most. The universal problem was known. I…

Hello, I made this site to combat misinformation on the internet by allowing users to prove that their claim is valid by linking multiple sources and combining them in a single link It's very early stage so I would love feedback on: - What types of claims would be most useful to you? - How can I make verification/sourcing more robust? - Any features that would make this actually useful vs just interesting? Thanks in advance, feel free to roast :)
