yes correct
i have recovered privatekey address 1
but i can't recover privatekey address 2...
If you have the private key for the first transaction, then you can calculate the k value as follows, where x is the private key:
k = (z
1 + r
1*x
1)/s
1Once you know k, which you say is reused in the second transaction, then you can just rearrange the equation above to calculate the private key for the second transaction:
x
2 = (k*s
2 - z
2)/r
