Thanks! that was an interesting watch. I watched the
videos he put up with the simulations. They do explain an overview of what's a blockchain, txs, and how every block is computed from the previous one, but it's still too superficial. I'd love material that is quite a bit more in-depth than these.
I can understand that.
Books are the best resource for in-depth information, as videos tend to be a little simplified compared to reality.
You also could try different cryptography related books to enhance your knowledge, for instance, elliptic curves.
Another way to understand Bitcoin is to use a wallet in expert mode, preferably on the testnet (to not lose your valuable BTC by mistake).
Yeah after a while, I do feel like that even for completely new concepts like Ethereum or POS coins, the main ingredient that I first need to hone up on would be cryptography. Only after that can I start experimenting with new structures or different logic.
