Mycelium has announced today the imminent shipping of its Entropy, a USB dongle whose only purpose is to securely generate Bitcoin paper wallets.
Mycelium Entropy just needs to be plugged into a USB compatible printer, and generates a large random number based on hardware entropy. That number is turned into a Bitcoin private key and a Bitcoin address, directly printed from the device before its memory is wiped out.
Despite production problems, the device should be shipped soon: “Once assembled, flashed, and packaged, they will all be shipped to Amazon distribution centers in Europe and US, and shipped out from there,” confirmed the company. A total of 911 orders have already been placed, following a crowdfunding campaign.
