Probably not helpful but in my mind ECDSA is like a universe sized game of whack-a-mole, and you can only use a mallet once. When you spend some bitcoin you make a mole pop up in a very specific hole to prove you own the coins. The problem is that if you reveal the starting hole you hit the mole on the head from anyone can spend your bitcoin. ECDSA is a clever trick that allows you to present the single use mallet as proof you actual hit the mole.

This is why “nonce reuse”(a random mallet) is a no no. If you give too much information out people can eventually backtrace your private key. “Nonce reuse” is like using the same mallet again, you’re giving out too much information and then hackers can triangulate all the variables from your transaction history on chain to derive your secret key (I think).

TBH I think cryptography and Bitcoin for “retard” would be a great podcast.

I agree, but I have no intent on starting a podcast, merely sharing apps, websites and retarded thoughts here as I go :) I have no idea of being able to figure out the secret from nonce reuse - I am retarded.. but I am very skeptical that this is the case. Any good content you can reference?

No good references but my interpretation was there was a random number (the nonce) involved in every transaction signing because in algebra if you get too many values in an equation you can figure out all the parts. Just stabbing in the dark to be honest.
