Description

Fourth generation of the Opendime: a small USB stick that allows you to spend Bitcoin like a dollar bill. Pass it along multiple times. Connect to any USB to check balance. Unseal anytime. Trust no one.

 

  • USB DRIVE

    Acts like a read-only USB flash drive. Works with any computer, laptop, or phone. A QR Image and Text files inside contain Bitcoin address and helpful information.

  • ULTRA SECURE

    The private key is generated inside the device, and is never known to any human, not even you!

  • COMPATIBILITY

    The Bitcoin world changes fast but Opendime is built on the fundamental Bitcoin features that haven't changed in five years.

  • NO TRUST

    Give an Opendime to anyone and they don't need to worry that you can take back the funds later. The private key is strictly in the device itself.

  • FREE TO USE

    This is physical Bitcoin as it was meant to be: just hand it to someone and they've got it. Pass it on multiple times! As simple as a handshake. No miner fees, no confirmation delays.

  • OPEN STANDARDS

    Uses Bitcoin message signing, normal (non HD) bitcoin payment addresses and private keys in WIF format.

 

REAL SECURITY

  • BASED ON PRIVATE KEYS

    Each Opendime holds one private key. It publishes the public key (payment address) to anyone and never reveals the key until "unsealed".

  • PIGGY-BANK ECONOMICS !?

    Yes. It's like a piggy-bank. You must destroy it to spend the funds. At first that seems expensive and wasteful, but it's a key part of our security model: you can trust a sealed Opendime, and it's obvious when it's been opened.

  • INSTANT AND OFF-CHAIN

    Since we are putting private keys into a physical form you can trust, you can simply hand around Opendime units to move amounts around. There are no pre-defined Bitcoin amounts with Opendime either. Store as much or as little as needed.
