The 1st Bitcoin Bearer Bond or just call it a "Bitcoin Stick"
Instantly take your bitcoins off chain and hold physical possession of the funds. Pass them along until ready to retrieve the funds by breaking a physical seal on the opendime to gain access to the private key necessary to sweep the funds.
Opendime is 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 to spend online. Trust no one.
PACKED WITH FEATURES
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.
The private key is generated inside the device, and is never known to any human, not even you!
The Bitcoin world changes fast but Opendime is built on the fundamental Bitcoin features that haven't changed in five years.
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.
Uses Bitcoin message signing, normal (non HD) bitcoin payment addresses and private keys in WIF format.
