Provision: a bitcoin wallet
Provision is a bitcoin wallet based on three concepts:
- all secure operations performed on an air-gapped machine
- all products transported by USB drive to an online machine
- guaranteed to have no entropy re-use
An air-gapped machine, or a machine that has never been connected to the internet, reduces the attack surface of the environment used to operate safely with bitcoin.
No secrets are ever placed on the USB drive, leaving everything secure on the offline machine.
Creating your own entropy, e.g. via rolling a die, is the most secure guarantee for cryptographic operations available.
Provision also enables secure message encryption and signing using the same underlying software as Bitcoin.
Written in pure Python with no third-party dependencies.
Code available upon request.
