Bitcoin wallet keys emerge from radioactive decay

An open-source Bitcoin seed generator has converted radioactive decay events into 12-word and 24-word BIP39 recovery phrases using an offline hardware device. Summary Entropy32 Plus converts radioactive decay timing into twelve or twenty-four word Bitcoin recovery phrases offline. Firmware collects 512 comparison bits before conditioning the pool with its SHA-256 implementation locally offline. The device stores generated words temporarily in RAM and provides a manual wipe command afterward. Its developer says entropy quality remains unvalidated under NIST SP 800-90B testing and independent review. Open-source files cover firmware, circuit boards, fabrication data, enclosures and the BIP39 wordlist for inspection. The Entropy32 Plus repository, published by developer Alexander Higgins in September 2026, contains the project’s firmware, circuit-board designs, fabrication files and printable enclosure. Higgins describes the device as an experimental, educational project and warns users not to trust it with substantial funds before an independent review. Known as “The Universe Bifurcator,” the device takes pulses from a Geiger counter and measures the time between detected events. Its...
