bip39 VS bitcoinbook

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.

You can try Ian Coleman's tool at : https://iancoleman.io/bip39/

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!

"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.
