amaclin1, these P2PKH addresses are compromised no matter what—around 4 BTC is at risk. The transactions accidentally reused the R value between addresses due to a biased PRNG. I’m looking for a brute-force method to recover the nonce or any other approach. I already have a private key that might be the master key for all these
Do you understand me?
I can provide you a number of valid {R,S,Z
n,P
n} for any given R,S
Without knowledge how 'K' was choosen this information has no sense.
Just a math.
