Introduction
The Bitcoin white paper PDF was encoded in the blockhain in April 2013, in transaction 54e48e5f5c656b26c3bca14a8c95aa583d07ebe84dde3b7dd4a78f4e4186e713
of block 230,009
.
The transaction contains 947 outputs and the sender spent almost 60 millions sats as miner fee! Some explanations on how the paper is encoded in the transaction is given in a Bitcoin StackExchange post from 2015.
This guide explains how to reconstruct the Bitcoin white paper PDF using your own verified blockchain data. No matter how censored the white paper could become (see this article about white paper copyright claims), you will know how to recreate and share the foundational document of Bitcoin.
Extract the whitepaper directly from Bitcoin Core
-
With the “admin” user, create a new directory to store the PDF and move to this directory
$
mkdir
bitcoin-white-paper$
cd
bitcoin-white-paper -
Install
jq
, a JSON processor that will be used to parse the transaction data$
sudo
apt update$
sudo
aptinstall
jq--install-recommends
-
Use
bitcoin-cli
to download and create the PDF$
bitcoin-cli getrawtransaction 54e48e5f5c656b26c3bca14a8c95aa583d07ebe84dde3b7dd4a78f4e4186e713true

How does this work?
Here’s how the long command from above actually works:
-
With
bitcoin-cli getrawtransaction
, you get the raw data of the transaction with this specific transaction id. This command returns the result as a JSON object.You can run
bitcoin-cli help getrawtransaction
to learn more. -
The result is handed over (“piped”) to the next command:
jq -r '.vout[].scriptPubKey.asm'
. This instruction extracts the assembly data from the “scriptPubKey” for all transaction outputs, where the Bitcoin whitepaper data is stored.Run
jq --help
for more information. -
The result is then piped into the
cut -c3-
command, which cuts off the first two characters on every line.Check out
cut --help
to learn more. -
The command
xxd -p -r
takes the previous result as input and converts everything from hex into binary encoding.Run
xxd --help
for more about this command. -
Then,
tail +9c
output the data starting with the 9th byteUse
tail --help
to learn more. -
Finally, the data is piped into
head -c 184292
. This command sends the first 184292 bytes onwards.Run
head --help
for more information. -
The argument
> bitcoin.pdf
then takes the whole data input stream and stores it into the file “bitcoin.pdf”.
This concatenation of simple commands is a shining example of one of the core principles of Linux. The character |
allows to string them together to create powerful yet efficient data processing.
Send the PDF to your computer
To be read, the PDF can now be sent from the remote node to your local computer using the scp utility.
-
macOS or Linux
On your local computer, open a terminal window and type the following command. Replace YourNodeIP with the Raspberry Pi IP address (or
raspibolt.local
if it works) and do not forget the dot at the end of the line (representing the destination of the file, here the ‘Home’ folder of your local computer).$
scp admin@YourNodeIP:~/bitcoin-white-paper/bitcoin.pdf.
-
Windows
This also works with the PSCP tool from PuTTY that you can run from the command line. See How to Use Putty pscp to Copy Files for more information.
pscp admin@YourNodeIP:~/bitcoin-white-paper/bitcoin.pdf
.
-
The file should now be located in the Home folder of your local computer.
Send the PDF to your Telegram account
🚨 Privacy warning: Using this method will leak your IP address to the Telegram server.
-
Follow this tutorial to create a new Telegram bot (up to, and including, ‘Get the Chat ID’). Write down the bot ID and the chat ID in a secure location (e.g., your password manager).
-
Send the white paper to your bot (replace YourChatID and YourBotID by respectively your chat and bot ID obtained from the previous step). It might take a few seconds.
$
curl-v
-F
"chat_id=YourChatID"
-F
document
=
@/home/admin/bitcoin-white-paper/bitcoin.pdf https://api.telegram.org/botYourBotID/sendDocument -
The PDF should now be available for download in your Telegram bot.
Get the whitepaper from BTC RPC Explorer
The BTC-RPC-Explorer has also a functionality to extract the data from the node and display the PDF in the web browser.
- Open your Explorer at https://raspibolt.local:4000/ (replace raspibolt.local with your node IP address if needed).
- Look-up the transaction ID in the explorer:
54e48e5f5c656b26c3bca14a8c95aa583d07ebe84dde3b7dd4a78f4e4186e713
- Click on the link “bitcoin whitepaper” in the top box, this will generate the PDF from the node blockchain and displays it as a pdf file in the browser.
- Alternatively, use the following URL: https://raspibolt.local:4000/bitcoin-whitepaper
