* [Baseball card template: 24-word SeedQR (29x29)](docs/seed_qr/printable_templates/Seed_QR_Card.pdf)
Best practice is to verify the downloaded .zip file containing the Raspberry Pi Lite OS matches the published SHA256 hash of the file; for additional reference that hash is: c5dad159a2775c687e9281b1a0e586f7471690ae28f2f2282c90e7d59f64273c. After verifying the file's data integrity, you can decompress the .zip file to obtain the operating system image that it contains. You can then use Balena's Etcher tool (https://www.balena.io/etcher/) to write the Raspberry Pi Lite software image to a memory card (4 GB or larger). It's important to note that an image authoring tool must be used (the operating system image cannot be simply copied into a file storage partition on the memory card).

The manual SeedSigner installation and configuration process requires an internet connection on the device to download the necessary libraries and code. But because the Pi Zero 1.3 does not have onboard wifi, you have two options:
_note: CompactSeedQR is an advanced feature that can be enabled in Settings_
1. Run these steps on a separate Raspberry Pi 2/3/4 or Zero W which can connect to the internet and then transfer the SD card to the Pi Zero 1.3 when complete.
2. OR configure the Pi Zero 1.3 directly by relaying through your computer's internet connection over USB. See instructions [here](docs/usb_relay.md).
---------------
For the following steps you'll need to either connect a keyboard & monitor to the network-connected Raspberry Pi you are working with, or SSH into the Pi if you're familiar with that process.
# Manual Installation Instructions
see the docs: [Manual Installation Instructions](docs/manual_installation.md)
### Configure the Pi
First things first, verify that you are using the correct version of the Raspberry Pi Lite operating system by typing the command:
```
cat /etc/os-release
```
The output of this command should match the following text:
```
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"
```
Now launch the Raspberry Pi's System Configuration tool using the command:
```
sudo raspi-config
```
Set the following:
* `Interface Options`:
* `Camera`: enable
* `SPI`: enable
* `Localisation Options`:
* `Locale`: arrow up and down through the list and select or deselect languages with the spacebar.
* Deselect the default language option that is selected
* Select `en_US.UTF-8 UTF-8` for US English
* You will also need to configure the WiFi settings if you are using the #1 option above to connect to the internet
When you exit the System Configuration tool, you will be prompted to reboot the system; allow the system to reboot and continue with these instructions.
Install these dependencies (you can use this entire text string to install them all at once):
```
sudo apt-get update && sudo apt-get install -y wiringpi python3-pip python3-numpy python-pil libopenjp2-7 git python3-opencv libzbar0 python3-picamera libatlas-base-dev qrencode
```
Install the [C library for Broadcom BCM 2835](http://www.airspayce.com/mikem/bcm2835/):
```
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.60.tar.gz
tar zxvf bcm2835-1.60.tar.gz
cd bcm2835-1.60/
sudo ./configure
sudo make && sudo make check && sudo make install
cd ..
rm bcm2835-1.60.tar.gz
```
Install the "virtualenvwrapper" tool:
```
pip3 install virtualenvwrapper
```
Edit your bash profile with the command `nano ~/.profile` and add the following to the end:
```
export WORKON_HOME=$HOME/.envs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source /home/pi/.local/bin/virtualenvwrapper.sh
```
Then `CTRL-X` and `y` to exit and save changes.
Now create the python virtualenv for SeedSigner with these two commands:
```
source ~/.profile
mkvirtualenv --python=python3 seedsigner-env
```
Now download the SeedSigner code:
```
git clone https://github.com/SeedSigner/seedsigner
```
Install the necessary Python dependencies:
```
cd seedsigner
pip3 install -r requirements.txt
cd ..
```
Modify the systemd to run SeedSigner at boot:
```
sudo nano /etc/systemd/system/seedsigner.service
```
Add the following contents to the text file that was created:
```
[Unit]
Description=Seedsigner
[Service]
User=pi
WorkingDirectory=/home/pi/seedsigner/src/
ExecStart=/home/pi/.envs/seedsigner-env/bin/python main.py
Restart=always
[Install]
WantedBy=multi-user.target
```
Use `CTRL-X` and `y` to exit and save changes.
Run `sudo systemctl enable seedsigner.service` to enable service on boot. (This will restart the seedsigner code automatically at startup and if it crashes.)
Now reboot the Raspberry Pi with the command:
```
sudo reboot
```
After the Raspberry Pi reboots, you should see the SeedSigner splash screen and the SeedSigner menu subsequently appear on the LCD screen (note that it can take up to 60 seconds for the menu to appear).
Next, disable and remove the system's virtual memory / swap file with the commands:
```
sudo apt remove dphys-swapfile
sudo rm /var/swap
```
For those who will use the SeedSigner installation for testing/development, it can be helpful to change the system's host name so it doesn't potentially conflict with other Raspberry Pi's that may already be present on your network. (For those who don't plan to use the installation for testing or development, you can skip this portion of the process.) To change the host name first edit the "hostname" with the command:
```
sudo nano /etc/hostname
```
and change "raspberrypi" to "seedsigner" (or another name). Use `CTRL-X` and `y` to exit and save changes. You'll also need to edit the "hosts" file with the command:
```
sudo nano /etc/hosts
```
and change "raspberrypi" to "seedsigner" (or the other name you previously chose). Use `CTRL-X` and `y` to exit and save changes.
It's also a good idea to change the system's password from the default "raspberry". Do do this, use the command:
```
passwd
```
You will be prompted to enter the current password (raspberry) and then to enter a new password twice. In our prepared release image, the password used is "AirG@pped!" (without quotes).
If you plan to use your installation on a Raspberry Pi that is not a Zero version 1.3, but rather on a Raspberry Pi that has WiFi and Bluetooth capabilities, it is a good idea to disable the following WiFi & Bluetooth, as well as other relevant services (assuming you are not creating this installation for testing/development purposes). Enter the followiing commands to disable WiFi, Bluetooth, & other relevant services:
```
sudo systemctl disable bluetooth.service
sudo systemctl disable wpa_supplicant.service
sudo systemctl disable dhcpcd.service
sudo systemctl disable sshd.service
sudo systemctl disable networking.service
sudo systemctl disable dphys-swapfile.service
sudo ifconfig wlan0 down
```
Please note that if you are using WiFi to connect/interact with your Raspberry Pi, the last command will sever that connection.
You can now safely power the Raspberry Pi off from the SeedSigner main menu.
If you do not plan to use your installation for testing/development, it is also a good idea to disable WiFi and Bluetooth by editing the config.txt file found in the installation's "boot" partition. You can add the following text to the end of that file with any simple text editor (Windows: Notepad, Mac: TextEdit, Linux: nano):
```
dtoverlay=disable-bt
dtoverlay=pi3-disable-wifi
```
If you used option #2 above and don't plan to continue to access your SeedSigner via SSH over USB, it is a good idea to reverse the steps you took to enable it -- those instructions can be found near the end of [this guide](docs/usb_relay.md).
Please remember that it can take up to a minute for the GUI to appear when subsequently powering your SeedSigner on.
### Optional: Run the tests

# Advanced developer notes
## Backup an SD card
You can back up and restore any size SD card but the process is a little inefficient so the bigger the source SD card, the bigger the backup will be and the longer it'll take to create (and even longer to image back to a new SD card), even if most of the card is blank.
You can restore a backup image to an SD card of the same or larger size. So it's strongly recommended to do repetitive development work on a smaller card that's easier to backup and restore. Once the image is stabilized, then write it to a bigger card, if necessary (that being said, there's really no reason to use a large SD card for SeedSigner. An 8GB SD card is more than big enough).
Insert the SD card into a Mac/Linux machine and create a compressed img file.
First verify the name of your SD card:
```
# Mac:
diskutil list
# Linux:
sudo fdisk -l
```
It will most likely be `/dev/disk1` on most systems.
Now we use `dd` to clone and `gzip` to compress it. Note that we reference the SD card by adding an `r` in front of the disk name. This speeds up the cloning considerably.
```
sudo dd if=/dev/rdisk1 conv=sparse bs=4m | gzip -9 > seedsigner.img.gz
```
The process should take about 15 minutes and will typically generate a roughly 1.1GB image.
To restore from your backup image, just use the Raspberry Pi Imager. Remember that you can only write it to an SD card of equal or greater size than the original SD card.

```
You will be prompted to enter the current password (raspberry) and then to enter a new password twice. In our prepared release image, the password used is `AirG@pped!` (without quotes).
### Install dependencies
```
sudo apt-get update && sudo apt-get install -y wiringpi python3-pip python3-numpy python-pil libopenjp2-7 git python3-opencv python3-picamera libatlas-base-dev qrencode
```
### Install `zbar`
v0.4.6 requires `zbar` at 0.23.x or higher.
see: [https://github.com/mchehab/zbar](https://github.com/mchehab/zbar)
#### Get the `zbar` binary
```
curl -L http://raspbian.raspberrypi.org/raspbian/pool/main/z/zbar/libzbar0_0.23.90-1_armhf.deb --output libzbar0_0.23.90-1_armhf.deb
sudo apt install ./libzbar0_0.23.90-1_armhf.deb
```
#### Or install `zbar` by compiling from source
This step isn't necessary. It's only if you prefer to compile `zbar` from source. The whole process takes about 30 minutes.
```
sudo apt-get install -y autopoint
cd ~/
git clone https://github.com/mchehab/zbar.git
cd zbar
git checkout 0.23.90
```
Configure the compiler settings and compile.
```
autoreconf -vfi && ./configure
make
make check
sudo make install
```
### Install the [C library for Broadcom BCM 2835](http://www.airspayce.com/mikem/bcm2835/)
```
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.60.tar.gz
tar zxvf bcm2835-1.60.tar.gz
cd bcm2835-1.60/
sudo ./configure
sudo make && sudo make check && sudo make install
cd ..
rm bcm2835-1.60.tar.gz
```
### Set up `virtualenv`
```
pip3 install virtualenvwrapper
```
Edit your bash profile with the command `nano ~/.profile` and add the following to the end:
```
export WORKON_HOME=$HOME/.envs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source /home/pi/.local/bin/virtualenvwrapper.sh
```
Then `CTRL-X` and `y` to exit and save changes.
Now create the python virtualenv for SeedSigner with these two commands:
```
source ~/.profile
mkvirtualenv --python=python3 seedsigner-env
cd seedsigner
setvirtualenvproject
```
For convenience you can configure your `.profile` to auto-activate the SeedSigner virtualenv when you ssh in. Once again `nano ~/.profile` and add at the end:
```
workon seedsigner-env
```
Optional: If you're going to be testing new code on the SeedSigner, you'll find yourself often needing to kill the SeedSigner code that automatically runs at startup (we'll be configuring this further down). As an extra convenience you can list the process id so that you can then kill it from the terminal:
```
ps aux | grep main.py
```
Save your changes with `CTRL-X` and `y`.
Now when you `ssh` in you'll see something like:
```
pi 297 65.4 9.7 74096 36736 ? Rsl 09:26 10:29 /home/pi/.envs/seedsigner-env/bin/python main.py
pi 857 0.0 0.4 7332 1876 pts/0 S+ 09:42 0:00 grep --color=auto main.py
```
The top line is our SeedSigner code running. To stop it, run:
```
kill 297
```
Where `297` is the process id listed in the output above (it'll be different each time).
### Download the SeedSigner code:
```
git clone https://github.com/SeedSigner/seedsigner
cd seedsigner
```
If you want to run a specific branch within the main SeedSigner repo, switch to it with:
```
git checkout yourtargetbranch
```
And if you want to test a pull request (PR), for example PR #123:
```
git fetch origin pull/123/head:pr_123
git checkout pr_123
```
where `pr_123` is any name you want to give to the new branch in your local repo that will hold the PR.
### Install Python `pip` dependencies:
```
pip3 install -r requirements.txt
cd ..
```
#### `pyzbar`
Note: The `requirements.txt` installs a fork of the python `pyzbar` repo (for now pointing to the fork in Keith's `kdmukai` github account [https://github.com/kdmukai/pyzbar](https://github.com/kdmukai/pyzbar)).
The fork is required because the main `pyzbar` repo has been abandoned. This [github issue](https://github.com/NaturalHistoryMuseum/pyzbar/issues/124#issuecomment-971967091) discusses the changes needed in order to support reading binary data from `zbar`, which is required for our `CompactSeedQR` format which writes byte data instead of strings. The changes specifically reference the following PRs which have already been merged into Keith's fork:
* [PR 76](https://github.com/NaturalHistoryMuseum/pyzbar/pull/76/files): enables scanning to continue even when a null byte (`x\00`) is found.
* [PR 82](https://github.com/NaturalHistoryMuseum/pyzbar/pull/82): enable `zbar`'s new binary mode. Note that this PR has a trivial bug that was fixed in Keith's fork.
### Configure `systemd` to run SeedSigner at boot:
```
sudo nano /etc/systemd/system/seedsigner.service
```
Add the following contents to the text file that was created:
```
[Unit]
Description=Seedsigner
[Service]
User=pi
WorkingDirectory=/home/pi/seedsigner/src/
ExecStart=/home/pi/.envs/seedsigner-env/bin/python main.py
Restart=always
[Install]
WantedBy=multi-user.target
```
_Note: If you'll be testing new code on the SeedSigner, you'll want to omit the `Restart=always` line._
Use `CTRL-X` and `y` to exit and save changes.
Run `sudo systemctl enable seedsigner.service` to enable service on boot. (This will restart the seedsigner code automatically at startup and if it crashes.)
Now reboot the Raspberry Pi with the command:
```
sudo reboot
```
After the Raspberry Pi reboots, you should see the SeedSigner splash screen and the SeedSigner menu subsequently appear on the LCD screen (note that it can take up to 60 seconds for the menu to appear).
### Further OS modifications
Disable and remove the system's virtual memory / swap file with the commands:
```
sudo apt remove dphys-swapfile -y
sudo apt autoremove -y
sudo rm /var/swap
```
## Local testing and development
For those who will use the SeedSigner installation for testing/development, it can be helpful to change the system's host name so it doesn't potentially conflict with other Raspberry Pis that may already be present on your network. (For those who don't plan to use the installation for testing or development, you can skip this portion of the process.) To change the host name first edit the "hostname" with the command:
```
sudo nano /etc/hostname
```
and change "raspberrypi" to "seedsigner" (or another name). Use `CTRL-X` and `y` to exit and save changes. You'll also need to edit the "hosts" file with the command:
```
sudo nano /etc/hosts
```
and change "raspberrypi" to "seedsigner" (or the other name you previously chose). Use `CTRL-X` and `y` to exit and save changes.
### Set a static IP
Your local machine that `ssh`s into the SeedSigner can sometimes get confused if you're connecting to different SeedSigners that are all identified as `pi@seedsigner.local`. In this case it helps to set a static ip and just `ssh` directly to that instead.
First find your current `nameserver`:
```
sudo cat /etc/resolv.conf
```
This is the address of your local machine that is connected to your SeedSigner via usb (or it'll be the wifi router's address if you're using a Raspi with wifi and are keeping it enabled for `ssh` access).
Set a static ip: `sudo nano /etc/dhcpcd.conf` and add to the end:
```
interface usb0
static ip_address=192.168.1.200/24
static routers=192.168.1.254
static domain_name_servers=192.168.1.254
```
* `interface` will be `usb0` for usb connections; `wlan0` for wifi.
* `static ip_address` is the ip address you want the SeedSigner to use. It should match the `nameserver` ip you found above for all but the last part of the ip (note: the `/24` should always be included as-is).
* `static routers` should be your `nameserver` ip.
* `static domain_name_servers` should also be the `nameserver` ip.
`CTRL-X` and `y` to save changes.
After your next reboot, access this SeedSigner using its new static ip:
```
ssh pi@192.168.1.200
```
### More convenient `ssh` access:
Power SeedSigner devs will find themselves connecting to a lot of different SeedSigners. This can cause headaches with `ssh`'s built-in protections; a different device that uses the same `ssh` credentials is normally a potential spoofing attack. But we're doing this to ourselves on purpose and so we can carve out exceptions.
On your local machine, run `nano ~/.ssh/config` and add to the end:
```
host seedsigner.local
StrictHostKeyChecking no
UserKnownHostsFile /dev/null
User pi
LogLevel QUIET
host 192.168.1.200
StrictHostKeyChecking no
UserKnownHostsFile /dev/null
User pi
LogLevel QUIET
```
The first entry prevents warnings for the default `pi@seedsigner.local` connections.
The second entry does the same for a specific static ip; you'll want this if you configure all your SeedSigners to use the same static ip.
`CTRL-X` and `y` to save changes.
#### Bypass `ssh` password
You can also configure the SeedSigner so that you don't have to enter the `pi` password when you `ssh` in.
run `ssh-copy-id` with the same values that you connect via `ssh`:
```
ssh-copy-id pi@seedsigner.local
# or if you're connecting over static ip, something like:
ssh-copy-id pi@192.168.1.200
```
You'll be prompted to enter the password to complete it.
_Note: If you don't have any ssh keys on your local machine, you'll need to create a set with `ssh-keygen -t ed25519 -C "your_email@example.com"`. Then try running `ssh-copy-id` again._
## Disable wifi/Bluetooth when using other Raspi boards
If you plan to use your installation on a Raspberry Pi that is not a Zero version 1.3, but rather on a Raspberry Pi that has WiFi and Bluetooth capabilities, it is a good idea to disable the following WiFi & Bluetooth, as well as other relevant services (assuming you are not creating this installation for testing/development purposes). Enter the followiing commands to disable WiFi, Bluetooth, & other relevant services:
```
sudo systemctl disable bluetooth.service
sudo systemctl disable wpa_supplicant.service
sudo systemctl disable dhcpcd.service
sudo systemctl disable sshd.service
sudo systemctl disable networking.service
sudo systemctl disable dphys-swapfile.service
sudo ifconfig wlan0 down
```
Please note that if you are using WiFi to connect/interact with your Raspberry Pi, the last command will sever that connection.
You can now safely power the Raspberry Pi off from the SeedSigner main menu.
If you do not plan to use your installation for testing/development, it is also a good idea to disable WiFi and Bluetooth by editing the config.txt file found in the installation's "boot" partition. You can add the following text to the end of that file with any simple text editor (Windows: Notepad, Mac: TextEdit, Linux: nano):

If you used option #2 above and don't plan to continue to access your SeedSigner via SSH over USB, it is a good idea to reverse the steps you took to enable it -- those instructions can be found near the end of [this guide](usb_relay.md).
Please remember that it can take up to a minute for the GUI to appear when powering your SeedSigner on.
### Optional: Run the tests

# SeedQR Format Specification
[SeedSigner](https://github.com/SeedSigner/seedsigner/) is an open source, DIY, fully-airgapped Bitcoin hardware wallet that wipes all private data from memory each time it's turned off. That means users need to re-enter their Bitcoin private key each time they use it.
To speed up this key entry process we have defined a way to encode a private key as a QR code that can be instantly scanned into a SeedSigner or potentially any other Bitcoin hardware wallet that has a camera.
The approach is specifically designed to encode the minimum possible amount of data in order to keep the resulting QR code small enough that it can be transcribed *by hand*. This sounds ridiculous at first, but remember that this is secret data that should never be stored in any digital medium. And even printers present some additional risk vectors.
<table align="center">
<tr><td><img src="img/handmade_qr.jpg"><br/><em>Obviously this SeedQR is just for demonstration purposes; never photograph your SeedQRs!</em></td></tr>
</table>
We have defined two QR formats:
* Standard SeedQR
* And a more advanced CompactSeedQR
Specifications for each follow below, as well as discussion of the pros and cons of each format.
## Quick Review of BIP-39 Mnemonic Seed Phrases
The typical method for backing up a Bitcoin private key is to store it as a [BIP-39](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki) mnemonic seed phrase that consists of 12 or 24 words.
Each word comes from a [list of 2048 words](https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt). The words themselves are meaningless; all that matters is the word's position number (aka index) in the word list.
For example, "tomato" is the 1,825th word in the list.
But code always starts counting list items with zero. So the index of "tomato" is actually `1824` (if you're looking at the github wordlist line numbers, just remember to always subtract one).
So we can transcode a 12-word seed into a series of indices:
```
1. vacuum 1924
2. bridge 222
3. buddy 235
4. supreme 1743
5. exclude 631
6. milk 1124
7. consider 378
8. tail 1770
9. expand 641
10. wasp 1980
11. pattern 1290
12. nuclear 1210
```
# "Standard" `SeedQR` Specification
We take the indices of the mnemonic seed phrase and concatenate them into one long stream of digits. Each index must be exactly four digits so shorter numbers must be zero-padded (`12` becomes `0012`).
Using the example above:
```bash
# with zero-padded indices:
1924 0222 0235 1743 0631 1124 0378 1770 0641 1980 1290 1210
# final assembled digit stream:
192402220235174306311124037817700641198012901210
```
This digit stream is then encoded into a QR code.
### QR Code Data Formats
It's important to note here that QR codes can encode data in a number of different ways:
<table align="center">
<tr><td align="center"><img src="img/qrcode_capacity.png"><br/><em><a href="https://www.qrcode.com/en/about/version.html">qrcode.com</a></em></td></tr>
</table>
QR codes are typically used to encode a website url, in which case the "Alphanumeric" format has to be used (the encoded data can consist of upper- and lowercase letters, numbers, and certain allowed symbols).
If you have a long url like `https://ohnoihavealongurl.com` (29 characters), the chart shows that it would not fit in a 21x21 QR code; its max capacity is 25 alphanumeric chars. But it's within the 47-char capacity of the 29x29 size.
### Bit efficiency matters
Notice that the "Numeric" column has greater capacity. This is because when you have fewer possible characters to encode, it takes less data to specify each one.
Alphanumeric format supports 44 possible characters. They are encoded as pairs, so that means there are 44^2 = 1,936 possible pairings to describe. Each pair can then be encoded using 11 bits:
```
2^11 = 2048
```
If you only used 10 bits, you could only specify 2^10 = 1,024 possible values; not nearly enough for the 1,936 possible pairings. 11 bits is the best this format can do.
The Numeric format is able to store 3 digits using just 10 bits. The largest possible 3-digit number is `999`, therefore 10 bits (2^10 = 1,024) is sufficient.
This is why a 25x25 QR code can only store 47 alphanumeric characters vs 77 numeric digits. It's the same amount of total data in terms of bits:
```
47 alphanumeric chars / 2 chars per pair * 11 bits per pair = 259 bits
77 numeric digits / 3 digits per group * 10 bits per group = 257 bits
```
*(both formats round up to 260 bits)*
Armed with this knowledge, we're ready to encode our SeedQR.
## Generate the SeedQR
Our SeedQR data will consist solely of numeric digits so that we can use the more efficient "Numeric" format. Our 12-word mnemonic seed phrase requires:
```
12 words * 4 digits per word = 48 digits
```
48 numeric digits won't fit in a 21x21 using the "L" (Low) error correction mode (max Numeric capacity is 41) but will easily fit in a 25x25:
<table align="center">
<tr><td><img src="img/standard_12word.png"></td></tr>
</table>
If you scan this QR code with your phone, you'll see the human-readable digit stream:
<table align="center">
<tr><td><img src="img/phone_screenshot_standard.jpg"></td></tr>
</table>
And see for yourself that the digit stream matches what was generated above from the mnemonic seed word indices.
```
192402220235174306311124037817700641198012901210
```
At this point it is trivial for a SeedSigner or other Bitcoin hardware wallets to parse the digit stream back into the individual BIP-39 wordlist indices and rebuild your entire mnemonic seed phrase.
Looking back at the QR code capacity chart for Numeric data, we know exactly how large the resulting SeedQRs will be:
```
12-word mnemonic (48 digits) = 25x25
24-word mnemonic (96 digits) = 29x29
```
Examples:
<table align="center">
<tr>
<td align="center"><img src="img/standard_12word.png"><br/>12-word Standard SeedQR</td>
<td align="center"><img src="img/vector1_standard_24word.png"><br/>24-word Standard SeedQR</td>
</tr>
</table>
# `CompactSeedQR` Specification
The `CompactSeedQR` format builds upon the "Standard" `SeedQR` format by further optimizing how the data is stored in order to generate smaller QR codes that are easier to transcribe by hand.
Notice in the QR code capacity chart above that there's also a "Binary" column, but its relative capacity count initially looks pretty unimpressive; a 25x25 QR code is limited to 32.
But here the unit being described isn't alphanumeric characters or numeric digits; it's max number of bytes.
```
1 byte = 8 bits
```
Rather than having the QR format interpret our data as numbers or characters, we can directly encode the relevant bits that determine our Bitcoin private key.
We can extract exactly those bits from our mnemonic seed phrase digit stream that we generated above.
Let's bring back our mnemonic seed phrase's individual indices:
```bash
1924 0222 0235 1743 0631 1124 0378 1770 0641 1980 1290 1210
```
We know that the BIP-39 wordlist contains exactly 2048 words. That means we will need 11 bits to express each index in binary (2^11 = 2048; not a coincidence!):
```
1924 11110000100
0222 00011011110
0235 00011101011
1743 11011001111
0631 01001110111
1124 10001100100
0378 00101111010
1770 11011101010
0641 01010000001
1980 11110111100
1290 10100001010
1210 10010111010
```
We concatenate all those binary values to one large 132-bit stream:
```
111100001000001101111000011101011110110011110100111011110001100100001011110101101110101001010000001111101111001010000101010010111010
```
BIP-39 specifies a checksum word at the end of each mnemonic seed phrase. In a 12-word mnemonic, the last 4 bits are the checksum. In a 24-word mnemonic, the last 8 bits are the checksum.
The checksum is trivially calculated from the prior bits (in this case, the first 128 bits of our stream). Therefore we do not need to include those bits in our CompactSeedQR.
```
12-word mnemonic = 12 words * 11 bits per word = 132 bits
12-word CompactSeedQR = 132 bits - 4 checksum bits = 128 bits
24-word mnemonic = 24 words * 11 bits per word = 264 bits
24-word CompactSeedQR = 264 bits - 8 checksum bits = 256 bits
```
How well will these bit streams fit in a "Binary" QR code? Referring back to the QR code capacity chart we find the following for the "L" (Low) error correction mode:
```
12-word mnemonic: 128bits / 8 bits per byte = 16 bytes = 21x21
24-word mnemonic: 256bits / 8 bits per byte = 32 bytes = 25x25
```
So by using the optimally-efficient Binary encoding, we have made each CompactSeedQR one size smaller than its Standard SeedQR counterpart.
Examples:
<table align="center">
<tr>
<td align="center"><img src="img/vector4_compact_12word.png"><br/>12-word CompactSeedQR</td>
<td align="center"><img src="img/vector1_compact_24word.png"><br/>24-word CompactSeedQR</td>
</tr>
</table>
# Standard SeedQR vs CompactSeedQR
Here are the two formats side-by-side.
The same 12-word seed in each format:
<table align="center">
<tr>
<td align="center"><img src="img/vector4_standard_12word.png"><br/>Standard SeedQR (25x25)</td>
<td align="center"><img src="img/vector4_compact_12word.png"><br/>CompactSeedQR (21x21)</td>
</tr>
</table>
The same 24-word seed in each format:
<table align="center">
<tr>
<td align="center"><img src="img/vector1_standard_24word.png"><br/>Standard SeedQR (29x29)</td>
<td align="center"><img src="img/vector1_compact_24word.png"><br/>CompactSeedQR (25x25)</td>
</tr>
</table>
Since the goal of the SeedQR concept is to make it easy to transcribe by hand, it's natural to assume that the CompactSeedQR is better.
Let's compare actual "real estate" in each size. All of our QR sizes have three large 8x8 registration blocks in the corners. 29x29 and 25x25 have a smaller 5x5 registration block in the lower right.
```
29x29 - (3*8x8) - 5x5 = 624 blocks
25x25 - (3*8x8) - 5x5 = 408 blocks
21x21 - (3*8x8) = 249 blocks
```
So by shrinking a 24-word Standard SeedQR from 29x29 down to a CompactSeedQR at 25x25, we've reduced the area we have to manually transcribe to:
```
408 / 624 = 65%
```
And similarly, shrinking a 12-word 25x25 Standard SeedQR down to a CompactSeedQR at 21x21:
```
249 / 408 = 61%
```
If you're manually punching holes into a metal SeedQR plate, that's cutting out about 35-40% of the work!
<table align="center">
<tr><td><img src="img/seedqr_plate.jpg"></td></tr>
</table>
But there are other tradeoffs to consider.
## Recoverability
If you lose your SeedSigner or somehow the project is abandoned or banned, how will you read back your SeedQR?
With the Standard SeedQR format this is trivial--any smartphone can decode the numeric digit stream. But the CompactSeedQR's raw byte data is not decipherable in the same way. Most QR readers today assume the data is either alphanumeric or human-readable numeric data. Because of this assumption, they misinterpret the binary format data:
<table align="center">
<tr>
<td align="center"><img src="img/phone_screenshot_standard.jpg"><br/>Standard SeedQR</td>
<td align="center"><img src="img/phone_screenshot_compact.jpg"><br/>CompactSeedQR</td>
</tr>
</table>
The clearly readable Standard SeedQR digit stream can be manually transcribed back to a mnemonic seed phrase with no other computer assistance, if need be.
It's just the above process in reverse:
```bash
# 12-word Standard SeedQR digit stream
192402220235174306311124037817700641198012901210
# Separate out into 4-digit individual indices
1924 0222 0235 1743 0631 1124 0378 1770 0641 1980 1290 1210
# Look up each BIP-39 index number (index+1 if using the github list!)
1. vacuum 1924
2. bridge 222
3. buddy 235
4. supreme 1743
5. exclude 631
6. milk 1124
7. consider 378
8. tail 1770
9. expand 641
10. wasp 1980
11. pattern 1290
12. nuclear 1210
```
It would be much more difficult to manually recreate your seed from a CompactSeedQR. Tools like [zxing.org](https://zxing.org/w/decode.jspx) can help you get the binary data out as a hexidecimal string:
<img src="img/zxing_screenshot.png">
All 12-word CompactSeedQRs will start with `41 0` (that specifies the binary data format and says the length of the data is 16 bytes) and end with `0 ec` (unused byte and a half).
All 24-word CompactSeedQRs will start with `42 0` (binary, data length is 32 bytes) and end with `0` (unused half a byte).
The remaining hexidecimal data is just an alternate representation of the 128-bit entropy for your 12-word mnemonic (or 256 bits for a 24-word mnemonic). Various programming tools exist to convert from hex back into mnemonic form.
## Obfuscation
Conversely, having limited support for reading binary QR codes and the complications described above are seen by some as an added security feature. Should someone steal your CompactSeedQR or take a photo of it, they'll have to be fairly savvy to know how to decode it.
# Some Additional Notes on QR Codes
Our main use case is to be able to quickly initialize a SeedSigner with your Bitcoin private key. But using a QR code as your key loader--or even as your permanent backup etched in metal--has other advantages.
QR codes are ubiquitous now so plenty of hardware and software exists to read and generate them.
QR codes have built-in error correction. The "L" error correction mode is described as having a roughly 7% correction rate.
In general, QR codes are incredibly resilient to unreadable blocks. For example, you often see the middle blocks intentionally covered over with a logo:
<table align="center"><tr><td><img src="img/standard_24word_with_logo.png"></td></tr></table>
This is right at the limit of SeedSigner's ability to read this 24-word SeedQR, despite the inaccessible blocks.
Similarly, QR codes can withstand human error during the manual transcription process. A few mis-coded blocks, a smeared ink blob, or other physical blemishes will generally not cause any problems.
