ok I got a #bitcoin bounty, I'll zap directly 10.000 sats to the first best answer to this question:

When you create a wallet of, lets say 12 word seed, and ad a passphrase to it, what happens really in the background?

I'm not a programmer, but I'd like to see the real thing in the workings when this happens, if you know what I mean. I know that you create a whole new wallet by adding the passphrase, but what happens with the code? what does the Bitcoin software do when one generates a seed + passphrase.

the answer can also be a good explanatory video or article.

Thanks for your time ! Btw you can verify my history that I always pay when promised

You can play with https://iancoleman.io/bip39/ to see what happens.

In short: without a passphrase, the 12/24 words are entropy and get hashed into your private key. With a passphrase, this is added to the entropy, creating a completely separate wallet.

The difference between the two is that the bip39 encoding (the 12/24 words) have a checksum built in, so if you make a mistake, it most likely will catch that. You can try this by changing one of the seed words if you generate a random seed.

The passphrase does not have a checksum, so any typo will create a completely new wallet.

Not the best explanation, but mainly a shill for Ian's great tool.

bc through that tool he posted I immediately understood the mechanism behind it. It also showed me how any mnemonic words are a representation. Great simple tool: https://iancoleman.io/bip39/

Other great answers here thanks everyone & until next bounty !
