How To Setup Bitcoin Core
This guide explains how to get started with a Passport cold storage wallet. The passport is a Bitcoin hardware wallet that is assembled in the U.
Taking self custody of your bitcoin means that you are ultimately responsible for your own wealth, there is no bank vault to protect you or a help line to reverse a transaction. Being able to transact without permission is powerful, and with great power comes great responsibility.
So, let's get your journey into self custody started on the right foot. Generally speaking, it is good practice to use a P. Box when ordering Bitcoin-related products or materials. This helps prevent your exposure to risks associated with data breaches.
If you have any suspicion that your device was tampered with in transit, contact hello foundationdevices. The Passport is shipped in a white cardboard box with a blue, tamper-evident security seal. There is nothing on the outside of the box which indicates it has anything to do with Bitcoin. The number printed on the security seal is not recorded by Foundation Devices, but the initial batch of Passports all shipped with label numbers that start with B, B or B If the tamper-evident tape is disturbed, it will reveal the word "VOID.
Inside the cardboard box you will find a bubble-wrapped box containing the Passport. This inner box also has a tamper-evident seal on it.
You will also find some stickers and a note card with some basic explanations on it about your new Passport. The founders edition includes a miniature copy of the Bitcoin white paper printed in the form of a passport. After removing the bubble wrap and cutting the tamper-evident seal, inside the inner box you will find your new Passport. All together, everything necessary to get started is included.
The Passport measures mm in length by 38 mm in width. To get started, simply remove the magnetic cover from the back of the device and insert the included AAA batteries. The back of the included informational card has a QR code that you can scan with your phone to visit the Foundation Devices setup page. Next, you'll see how to power on the Passport and verify the supply chain check to ensure the device is genuine.
This section demonstrates how to power on the Passport and execute the supply chain validation. There is a private key stored on the secure element used for this validation. By scanning a static public key QR code with the Passport, it will generate four words which are used as a checksum that only a valid Passport private key can produce. Hold down the button in the lower left-hand corner of the Passport for about half of a second until the device lights up.
After the initial boot, you will be greeted with a welcome message. Next, you will see a QR code that you can scan with your phone to visit the setup guide if you haven't done so already. For this next step, ensure your batteries are well charged, then you will want to have the supply chain validation QR code open on your computer or phone. This will launch the camera and you can then scan the validation QR code on your device's screen. The Passport will then display four words on the screen.
Enter these words into the interface under the validation QR code. You should receive a validation message confirming that your device is a legit Foundation device. At this point, it is a good idea to get a notepad and pen or pencil ready to write down some information that you will need to secure.
This section demonstrates how to set up the PIN for accessing your Passport. Have a notebook and pen or pencil ready. To start, there are a few considerations to understand and then the steps to complete this process are outlined. The PIN number is used to secure access to your Passport. Without the PIN number, your Passport will be inaccessible. There is no way to recover a lost or forgotten PIN, so be sure to secure your PIN in such a way that you will not lose access to it.
Best practice is to physically write this information down in a notebook that you keep private and secure. Throughout this guide, there are going to be a few pieces of information that will be sensitive in regards to accessing the Passport and the signing keys it will contain. By writing this information down on paper, you can mitigate the risks introduced using digital media.
For example, in a digital file, this information can be remotely accessed on a network connected computer if the computer is compromised. Additionally, other forms of digital media such as images or video can not only be accessed remotely on a compromised device but they could also be copied and transferred quickly and easily by anyone who has physical access to the computer or other device.
Although it is true that anyone with physical access to the handwritten information could easily snap a picture of it, at least the notebook could be easily hidden in an inconspicuous place or secured in a safe whereas putting a computer in a safe may not be convenient or practical.
Using a PIN that is easy to guess could result in loss of bitcoin if an adversary gets a hold of your Passport. There is benefit to using a PIN that is difficult to guess. The PIN must be at least six digits in length. You will enter the first four digits and then you will be presented with two anti-phishing words. Write down these anti-phishing words, these are unique words that are generated by using some entropy from the Passport in combination with your PIN's first four digits.
After establishing your new PIN, upon re-entry to the Passport, you will be presented with these same two anti-phishing words. If you are ever presented with different ant-phishing words then you either entered the first four digits of your PIN incorrectly or your device has been tampered with.
If that happens to you, do not proceed with accessing your device until you figure out which situation you are in at that point.
As a security feature, the Passport will brick itself if there are 21 failed PIN attempts. Once a valid PIN is entered, the counter resets to zero. After the supply chain validation from the last section, you should see a message on your Passport that explains some details about the PIN. Scroll down to the bottom of that message with the "down arrow. Next, you will be presented with a blank PIN entry dialog. Use the numbered keys on the Passport to enter the first four digits of your new PIN.
Immediately upon entry of the fourth digit, you will be presented with the two anti-phishing words. Write down the first four digits of your PIN along with these two anti-phishing words.
Speaking this information out loud could introduce a potential risk of exposing the details to any devices that may be listening to you. Then press the "next" button and enter the remaining part of your PIN and write that down, too.
This remaining part needs to be at least two digits long and can be as much as eight digits in length. Your PIN in its entirety can be up to 12 digits in length. In this example, the PIN "" is used. Do not use "" for your PIN. When finished press "enter. Again, press "enter" when finished and the Passport will save this information. From now on the PIN will be required to access your Passport.
A lost or forgotten PIN cannot be retrieved from the Passport. No one can assist you with recovering a lost or forgotten PIN. The Passport will brick itself after 21 failed PIN entries. Be sure to write down and secure your entire PIN and the two anti-phishing words. Once the Passport is finished saving the PIN details, you will be at the main menu. Before setting up your new cold storage wallet, it is a good idea to ensure the firmware is up to date.
Keeping the firmware on the Passport up to date is important as this is how new features are introduced, quality of life improvements are made, security issues are resolved and bugs are fixed. Foundation regularly releases firmware updates, so be sure to stay up to date with these as they occur.
Navigate to the official Foundation firmware page to see more details. In this section, updating the firmware will be demonstrated in two ways. The first way involves fewer steps but forgoes independent verification, the second way demonstrates using the developer's PGP public keys and signatures to cryptographically verify the integrity of the firmware file.
The Passport will only allow firmware to be installed if it has been signed by at least two out of four possible Foundation developer PGP keys.
This gives beginner or intermediate users the ability to update their firmware with a reasonable degree of confidence, while giving advanced users the ability to verify the integrity of the firmware themselves. Before getting started with either approach outlined below, first check your Passport to compare the currently installed firmware version with the currently available firmware version. Log into your Passport by powering it on, typing in the first four digits of your PIN, confirming your two anti-phishing words, and entering the remainder of your PIN.
There you will see the currently installed firmware version, the date of its release and a boot counter. The boot counter tells you how many times the Passport has been powered on. Compare the currently-installed firmware version to the displayed currently-available version on the Foundation firmware download page. If the installed version is lower than the available version, then you will want to update that.
If you have the latest firmware installed, then you can skip to the next section. Navigate to the Foundation setup page and click on the link to open the firmware download. If your computer is equipped with a microSD slot, then you can simply insert the microSD card.
Then safely eject the microSD card. The microSD card inserts to the port on the top of the Passport. The microSD card does not fully insert to the device, it will be sticking out about half way. Ensure the pins on the microSD card are facing up, the same direction as the face of the device.
On the next screen you will see a message warning you not to power off the Passport during the firmware update.

The goal of this guide is set up a Bitcoin Node that is useful for tinkering with as a developer. If you complete this guide successfully, you'll have a node that is in sync with the network, contains the full history of the Bitcoin blockchain, and is fully validating all transactions. This means you can interact with the Bitcoin Network at large without relying on any trusted third party. As a simple example of what can be done with this, we'll run an open source block-explorer, providing you with a trustless interface to view activity on the network. Because this guide is for developers, it assumes you're comfortable doing developery things, such as running Linux, using bash, and executing Python scripts. Where more in-depth usage of some other tech is an out of scope pre-requisite, I'll provide links to useful guides as appropriate for those portions.
