RE: Book Review - Mastering Bitcoin
You are viewing a single comment's thread:
and was shocked to realise that you could have the same public key generated by another,
I think what you meant to say was that one private key can control multiple public keys.
It sounds like you are saying you can generate a new public key with an old public key.
This sounds like a book that I would find extremely useful because I dabble in programming.
Sounds like a big commitment though I can't even remember the last time I actually read a book.
Maybe one day.

It is a great book explaining some of the SHA256 cryptography and how it is being applied. The coding inside the book was even for the different nodes, it was very comprehensive.
Yes, I think I made a mistake, what I meant was from what I understood that the wallet/signing device can generate you a random private key and that there is a chance that it is technically possible but mathematically improbable that you could generate a private key already in use.
