What’s the fingerprint for?

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.

Roll real dice for truly trustless entrophy!

This is actually very helpful. Am planning on going this route

That seed signer looks awesome!

So, instead of trusting the RNG on coldcard, you trust the dice-to-seed converter on seedsigner?

Sweet, leveling up. View quoted note →

You can still do this with a piece of paper and dice rolls if you want to remain 100% trustless..

This what you are referring to?

You know, this is not how you're supposed to roll dices for RNG, if you'd roll like that on a board RPG, the master would smack his book on your head lol

You can still use an airgapped hw device to do the checksum

Watch this video for more info

That is the approach everyone should take for trustless seed generation

Look up the list of 2048 words, use a D8 instead of d6 for easier math. You can do the entire process of creating a seed phrase on pen and paper without a device.

I have a five of 12, any use case ?

The next RNG exploit is going to be the discovery that some large dice makers dice are not correctly balanced and the resulting dice rolls are heavily skewed and the resulting search space for seeds is quite small.

This is great. Even better would be how to generate a seed without ANY hardware. Dice + BIP39 wordlist How do you do calculate the checksum word? View quoted note →
