Instead of blaming farts, which are obviously mine, on barking spiders or the dog, I now say, “that was AI”. The future is here.

What’s the fingerprint for?
Nick Berlin profile picture
I asked the bot here’s what it said if anyone else has the same question.

Here’s what it is:

* The dice rolls provide entropy to generate your 12- or 24-word BIP-39 seed.
* That seed is converted into a BIP-32 master private key.
* The corresponding master public key is hashed (using SHA-256 followed by RIPEMD-160), and the first 4 bytes of that hash are displayed as the fingerprint (typically shown as 8 hexadecimal characters, such as A1B2C3D4).

The fingerprint is useful because:

* It lets you verify you’re working with the expected seed without revealing the seed words.
* You can compare fingerprints across wallets (e.g., SeedSigner, Sparrow, BlueWallet) to confirm they all imported the same seed.
* It’s commonly used to identify keys in multisig setups.

A few important points:

* It’s not a security feature or a checksum. Different seeds can theoretically produce the same 4-byte fingerprint (a collision), though it’s very unlikely (1 in about 4.3 billion).
* It cannot be used to reconstruct your seed. It only serves as a convenient identifier.

It’s not exactly a rewarding task, to be honest, because things change from one model to the next and I have to adjust my safeguards every single time. An article like that would have a pretty short shelf life and would already be outdated in a year.

No I haven't, but at some point I did wanted to go....
