A dedicated hardware Bitcoin private key collider running on a $15 microcontroller. Checking 27 keys per second against 43,497 whale wallets. Will never work. Looks incredible doing it.
Let's be transparent about our performance metrics.
We believe in radical transparency. Here's why this will never, ever work.
Every P2PKH Bitcoin address holding 50+ BTC. Satoshi's genesis block. Binance cold storage. That guy who bought pizza for 10,000 BTC. We're coming for all of them.
Hand-rolled secp256k1, SHA-256, and RIPEMD-160. No dependencies. No compromises. No chance of success. But the code is *beautiful*.
240×536 pixels of pure AMOLED darkness. Bitcoin orange on true black. Watch your keys scroll by in real-time. It's like a fireplace, but for cryptography.
Core 0 crunches keys. Core 1 renders the UI. They work in perfect harmony to achieve absolutely nothing, together.
~8 comparisons per key instead of 43,497. We optimised the hell out of the part that doesn't matter. You're welcome.
Lifetime key count saved to flash. Survives reboots. Because losing track of how many keys you've wasted would be the real tragedy.
ESP32's built-in hardware random number generator. Every key is truly random. Mathematically guaranteed to be as useless as the last one.
HUNTING... CRUSHING... LOLLYGAGGING... MANIFESTING... PRAYING... Because staring at the same word for 10^39 years would get boring.
Open source. Free firmware. $15 in hardware. Infinite disappointment.
KEYFINDER.WTF is an art project / educational tool / conversation starter / cry for help.
No wallets were harmed in the making of this device.
No wallets will ever be harmed by this device.
