Bitcoin Seed Generator Harnesses Radioactive Decay for Randomness

Entroply32 Plus is an innovative open-source Bitcoin seed generator that uses radioactive decay as a physical source of randomness. The device captures decay event timings using a Geiger counter and processes them through SHA-256 to produce unbiased entropy. This entropy is then converted into BIP39 seed phrases, generating a secure way to create Bitcoin wallets.

The Entroply32 Plus device operates fully offline on a custom microcontroller board with a small OLED display, requiring no external software or wireless connection. However, the entropy quality has not yet been validated under official standards, so users are advised to verify the source or use it cautiously.
