Katamarani what settings are you using to get 1500 have a 2080ti and 1250-1300 is the highest I have gotten.

Also if you have a 2080ti you should join the pool.  Would love your contribution.

Hi ttdclient. Sorry I was very vague. I think I have the same like 1300. Was wild guess from memory. You have a nice project but unfortunately I will not join because I don't like wasting energy and I don't think the money can be split fair.

Make it donation to good cause and I would join.
But better make Pollard kangaroo to go for 110. I think it is more feasible.

This ranges are already scanned.
  

what do you use ? and what is your speed?

i try this and no luck yet
Code:
VanitySearch-1.15.2_bitcrack -stop -t 2 -r 500 -s  000000000000000000000000000000000000000000000000cdf0d690b6af0000 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN

VanitySearch-1.15.2_bitcrack uses non-sequential search, there are dips in the range
Vanity.cpp line 1530.
Code:
void VanitySearch::getGPUStartingKeys(int thId, int groupSize, int nbThread, Int *keys, Point *p, uint64_t *n_count) {
//printf("\n[gpu-rekey][Th#%u][gsize#%u][nbT#%u][%u] \n", thId, groupSize, nbThread, *n_count);
  for (int i = 0; i < nbThread; i++) {
    if (rekey > 0) {
      //keys[i].Rand(256);
 
 keys[i].Set(&startKey);
 Int off((uint64_t)i);
 off.Mult((uint64_t)((rekey * 1000000) / nbThread));
 off.Add((*n_count)*(rekey * 1000000));//                    <-- !!! The no Sequential search !!!
 keys[i].Add(&off);
 //printf("\n[rekey][i#%u][count#%u] 0x%064s \n", i, *n_count, keys[i].GetBase16().c_str());

I use the code Wink and any rekey
Code:
void VanitySearch::getGPUStartingKeys(int thId, int groupSize, int nbThread, Int *keys, Point *p, uint64_t *n_count) {

  for (int i = 0; i <= nbThread; i++) {
    if (rekey > 0) {
      // Sequential search (no dips)
  rekey = nbThread;
  // ;)
  keys[i].Set(&startKey);
  Int off((uint64_t)i);
  off.ShiftL(20);
  //off.Mult((uint64_t)((rekey * 1000000) / nbThread));
  //off.Add((*n_count)*(rekey * 1000000));
  if (*n_count != 0) keys[i].Add(((*n_count)*(rekey * 1048576) + 1048576));
  keys[i].Add(&off);
  // Check GPU Start Key
  if (i < 5) printf("\n GPU Start Key %d: %s nbThread %d ", i, keys[i].GetBase16().c_str(), nbThread);
  if (i == nbThread) printf("\n GPU Start Key %d: %s nbThread %d \n", i, keys[i].GetBase16().c_str(), nbThread);
 
    }
Result
Code:
VSearch bit64 key range 0-100 percent v1.15
key from 0x8000000000000000 to 0xffffffffffffffff

This is little slow. I get much better speed with Bitcrack on rtx2080ti (about 1500 Mkeys).

I also sell Pollard Kangaroo.
Test me please with 85 bit key.

What is the fee?

Test Address  85 bit
Public Key : 0322d1b4a9af22c3529d7e0822673386165ea71cd6d339ccd019afa5cecdf1f015
Compress Address: 1N4Nma9JLgtZ9Ju7R8Dida1JNSU9U8h1LJ

How much will it take?

Can you please check in python 2 and write:
import math
math.log(, 2)

and check that it is 84.xxx?


edit: Your public key does not seem to be 85 bit.

The forum moderators here are not very competent so I will leave.
Zielar, if you want to team up and share 50%/50% please leave your contact details public somwhere here. Thank you.

85 bit?

Yes sorry my program sucks big time. Sorry for bothering.

Wanting to understand and test it on the empty wallet with 2 ^ 65 to which we know the public key (x, y) how to get the target which is the private key ... in this example all values are in DEC ... I did not want to wake up before testing, but since I'm starting to make an idiot of myself by asking questions so little clear that when I read, I do not understand them myself - I've given above what I mean :-)

Drotika is the best but not free


drotika can't even solve the easy tests from the users here. you and drotika are the same person?
