Extracting and Decoding the Bitcoin Genesis Script

vibe wrote this blog. As an experiment, I created a vlog about why I don't think the inscription on the genesis block is the same as ordinals. First, I extracted the mp3 file from the video using VLC media player. Then I converted the audio file into text. I asked GPT 5 mini on [duck.at](https://duck.ai/)to turn the transcript into a blog using the following prompt(I left the typos in for effect):

Thanks, marc — quick clarifying questions before I convert this into a blog post and suggest a title...

*My dumb-ass natural intelligence**:

the target audience is bitcoin developers. it should be a technical explanitory post on how to extract and decode the Genesis script between 400 and 600 words.



**GPT-mini**

Thanks, marc — one last quick check: which OS should the terminal commands target, Linux only or include macOS? (You previously mentioned Linux; confirm if macOS support is needed.)

Once you confirm, I’ll produce the 400–600 word technical explanatory post and suggested title.

The Bitcoin Genesis block contains an embedded input script that’s often dismissed as “spam.” For developers, that payload is a useful historical artifact — and it’s straightforward to extract and decode on Linux. This short guide shows the exact steps used to pull the scriptSig hex from block 0 and decode the ASCII message it contains.

Step 1 — fetch the scriptSig hex

Open blockstream.info (or another block explorer) and navigate to block 0 (the Genesis block).
Click into the block’s transaction details for the coinbase transaction and copy the scriptSig hex field. It’s a long hex string associated with the transaction input.

Step 2 — decode on Linux With the hex copied to your clipboard, run the following in a terminal (assumes clipboard paste via right-click or Ctrl+Shift+V):

bash

echo | xxd -r -p | strings -f -

Explanation:

echo sends the hex string to stdout.
xxd -r -p reverses hex encoding into raw bytes.
strings extracts printable ASCII sequences from the decoded bytes. For the Genesis coinbase you’ll see the historical message Satoshi embedded.

Alternative robust command (handles long hex and strips whitespace):

bash

printf '%s' "" | tr -d ' \n' | xxd -r -p | strings -f -

What you’ll see

newspaper

Decoding the Genesis coinbase script reveals a human-readable line referencing a 2009 newspaper headline about banks and bailouts — the canonical Satoshi message. The coinbase script includes extra bytes for the signature script format and versioning; extracting printable ASCII isolates the embedded text.

Why this isn’t “spam” (technical perspective)

The consensus rules allowed arbitrary coinbase input data; nodes accepted blocks as long as protocol rules were met.
Miners (including early adopters) validated and relayed blocks containing the payload, so the field’s presence was permitted by design.
The script data is non-consensus meta-data: it doesn’t affect UTXO rules or monetary policy, only the transaction’s input witness/script encoding.

Notes and caveats

The coinbase script can contain non-ASCII data; use tools like hexdump/xxd or a hex editor to inspect raw bytes for structured fields.
Some block explorers truncate long hex fields; copy the full scriptSig from the transaction raw hex if necessary.
This method is Linux-focused; commands should work in most POSIX shells.
For the record, I don't know if this information is accurate. I am merely experimenting with AI tools. If you are a developer who can verify this blogpost, please let us know. Here is the natural intelligence video I made that was converted into this blog post though.
