Products that do what Bitcoin Challenge. Try to steal a plain text private key you can use does
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:…

I built this machine so I could generate Bitcoin keys that I could trust. Air-gapped and simple to use and understand (mechanical). The Satoshi 9000 demo: https://youtu.be/bJiOia5PoGE The key value proposition of the machine is that it generates analog randomness in the physical world and converts it into digital (1’s and 0’s) randomness. Seamlessly. But it occurs to me that it may have other uses beyond crypto keys for your own use, such as: * Randomized clinical trials. Clinical trials need a high degree of transparency for ethical reasons; also, for legal reasons should it…

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…

A friend(@wolever) and I spent the weekend hacking up a small web app which makes it easy for you to sell digital goods for Bitcoins. Once a customer has clicked the “buy” button, we take care of giving them a unique address, monitoring that address for transactions, then securely notifying your website once a minimum number of confirmations have been received. Oh, ya, and then we send you the Bitcoins :) The website is here: BitWillet: http://www.bitwillet.com and there is a demo on the front page. (full disclosure: BitWillet uses the Willet, http://dev.getwillet.com, platform, of which I…
