Example:


d1=(k1*s1-z1)/r1
d1=000000000000000000000000000000000000000000000000000000000000000e (secret)
k1=(d1*r1+z1)/s1
k1=000000000000000000000000000000000000000000000000000000000000000f (secret)

Any ideas if we have a signature another signature

d2=k1^(n-2)-1
d2=22222222222222222222222222222221f6c1fb51f53ce22a19938412c66da24c (secret)

Added new information
d1=(k1*s1-z1)/r1
k1=(d1*r1+z1)/s1
r1=(k1*s1-z1)/d1
s1=(d1*r1+z1)/k1
z1=k1*s1-d1*r1

Any ideas if we have a signature another signature

d2=k1^(n-2)-1
k2=k1^(n-2)
r2=(k2*s2-z2)/d2
s2=(d2*r2+z2)/k2
z2=k2*s2-d2*r2

The task:

We have 2 signatures
d - private key
k - nonce
r - public key
s - Signature
z - Hash

d1=(k1*s1-z1)/r1
k1=(d1*r1+z1)/s1
r1=(k1*s1-z1)/d1
s1=(d1*r1+z1)/k1
z1=k1*s1-d1*r1

Any ideas if we have a signature another signature

d2=1/k-1
k2=1/k1
r2=(k2*s2-z2)/d2
s2=(d2*r2+z2)/k2
z2=k2*s2-d2*r2

We have 1/k and k, how can we calculate the value of k?

I installed the Trollcoin wallet on Windows 10 and I keep getting this error message. I tried to sync the wallet on 3 different Windows 10 machines with the same issue. If anyone could help that would be good.

Error:

A fatal error occurred. Trollcoin can no longer continue safely and will quit.
exception: st9bad_alloc
std:bad_alloc

Thanks,
Hi. Try it.

1. Free up RAM on your computer
2. Create a shortcut and add -splash=0. Example: "C:\Users\Youruser\Desktop\TrollCoin\TrollCoin.exe -splash=0"
3. Backup the TrollCoin.conf file and delete the original and run

There are a lot of alarming factors.
Git for more than 2 months
The site in git is one, there completely different
The pool does not work
The file of the wallet is on the file sharing service, not on the main site !!!!!
The wallet file requires administrative rights ...

AND data https://yadi.sk/i/Iq-_V7IB3WfPcC

The question is, who ran it ??
