How to use this site
This site does not create the wallet. It is an educational guide that walks a Bitcoiner through the steps to securely create a two of three Multi-sig wallet from the ground up. The most important part of the process is verification.
The source of this site is kept on the source archive. That is where the file can be downloaded for a code audit, or taken apart and changed.
Strict operational rule
This website does not connect to the Bitcoin network, it does not collect information about the person using it, and it cannot touch the funds. The work happens on the user’s own computer, and the network has to stay off while the keys are being made.
Step 01
Gather the materials
Materials needed:
- Five casino dice whose faces can be read
- A pencil and the recording grid
- Established private setting
- One computer
- Two USB drives
- Three titanium plates
- Sparrow 2.5.5, the required version
- Each file from that project’s own website, checked before it is copied onto a drive
Stop
Verify the files before going offline
The files have to pass the signature check before the computer is taken offline. A bad signature means the file is deleted. The work does not continue with that file.
Step 02
Go offline
It is critical that each key is made on a computer that is offline.
Tails OS is installed on one of the two USB drives. It can be booted on any computer, and it is designed to forget the session when the machine shuts down. When Tails is booted, networking is set to Disabled. This is effectively your offline computer.
Stop and verify
Do not skip the check
Every file used in this process has to be verified, because a compromised file compromises the funds. These are the files:
- Tails
- Sparrow 2.5.5 (required version)
- Electrum
- Ian Coleman page
- Dice converter
These files must be downloaded from their original sources.
Tails, Sparrow 2.5.5, Electrum, and the Ian Coleman page are not supplied by this site. Each one is downloaded from the project named on the official downloads page. A shortened link, or a page that only looks official, is not that source.
The dice converter is the one file this site provides. How to check it is on Verify the dice converter.
Step 03
Key Distribution
Once two offline programs have produced the same result, the key is valid. Once all three keys are created and can be reproduced in an offline, air-gapped environment, they can now be stamped into titanium plates. Those plates then have to be kept in three separate places. If two keys are stored in the same house, the separation is gone, and the setup has a single point of failure again.
