bitcoinbook VS bip39

"Mastering Bitcoin" by Andreas M. Antonopoulos: The printed version is not free, the complete text is available on GitHub. It's an excellent resource for understanding Bitcoin from a technical perspective.

The target is stored in the block header. You can see it in any block explorer labeled BITS or nBits. It is stored in a compressed format, as described in Mastering Bitcoin https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch10.asciidoc Scroll down to "Target Representation"

Mastering Bitcoin is a free book - https://github.com/bitcoinbook/bitcoinbook

I also highly recommend that you Read this book "Mastering bitcoin", its free and open source: https://github.com/bitcoinbook/bitcoinbook

You should read this chapter - it kinda explains why the chip need to be able to manipulate and access the private key. It works exactly the same way for every hardware wallet.

Download the offline version of the BIP39 tool via https://github.com/iancoleman/bip39/releases/latest. Right click on bip39-standalone.html and save the file.

You could make this with a Raspberry Pi Zero and the stand-alone version of the Coleman Web page+javascript https://github.com/iancoleman/bip39/releases/latest/

Since what I just said may be confusing... here it is in practice with a link so you can try it for yourself using Ian Coleman's Mnemonic Code Converter:

With Christmas coming around and the bull market upon us, I thought it would be a good time to remind everyone one about the art of mnemonic memorization. The idea is you take a BIP39 seed, then make a poem, story, limerick, or song using the words to help you remember. If you gift bitcoin, you can include the writing with the seed-card you provide to help the recipient remember as well. If you want to play along, go to Ian's BIP39 page and generate a valid seed mnemonic then see if you can't create a blurb of text that includes all the words.

13) Go to https://iancoleman.io/bip39/. There you need to change "Coin" value of the dropdown to "ETH – Ethereum". After that you can paste Secret phrase associated with Key 1 to “BIP39 Mnemonic” section

As I learned how to build websites, I wanted to use my new skill to help the crypto community in any way I can. So, I made a wallet generator website. It's like iancoleman BIP39, but with a nicer and more user-friendly design inspired by Tornado Cash, a simple way to make wallets from files/images, and support for Monero!

I looked on https://iancoleman.io/bip39/ but didn't see how I might get something useful there.
