Bro I know stride, this is theoreticaly simplify task, but I continue wok on it

stride example:

0xfff97bd5755eeea420453a14355235d382f6472f8568a18b2f057a1460297556

so, for take  range n is not so big task with sach stride, but, looks like may be needs brute range many many times because search is a collision search between R from your scrypt and K....


kangroo for ex example never stop and give good speed, so maybe....


bro, start of search range is always z , in my formulas what I make from your srypt. I think you find a nonce what bigger then z , too.

But this would require you knowing the key range. If you don't, it's going to take awhile. Like kangaroo as well.

Bro I know stride, this is theoreticaly simplify task, but I continue wok on it

stride example:

0xfff97bd5755eeea420453a14355235d382f6472f8568a18b2f057a1460297556

so, for take  range n is not so big task with sach stride, but, looks like may be needs brute range many many times because search is a collision search between R from your scrypt and K....


kangroo for ex example never stop and give good speed, so maybe.


bro, start of search range is always z , in my formulas what I make from your srypt. I think you find a nonce what bigger then z , too.


Br

start of search range is always Z signature?

yes !  I spend some time for make start range 0, moving z to enother part of formula. For mo understanding look to formula with i = 0 I think you understand why z is a start  ...I was understand this using this way

ok i try with different r,s,z. thanks.

Brother, I don't know if you use calculus, please, can you write a script that goes straight into RSZ, and he'll figure out what should be there and run it automatically, please, you're my God

Hello sir, I used your code, but it doesn't come out at the moment, it's a 2009 wallet transaction address, the output hash value, the last paragraph is pubkey, the above paragraph is pubkeyhasha, can you use your code to run out of the private key?

This is a rough hash of the transaction, I deleted it, if this is the case, can you use your code and enter the R S Z of this transaction to run it in 6 weeks

this strings of base point data:(in this example I am already put data of my base pooint:

  G.x.SetBase16("a0d287fb17a25850106cc52227......

  G.z.SetInt32(1);
  order.SetBase16


and use with stride


but, keyhunt bad work for me with stride,and I have no vast.ai account now for try stride with this software what has a good stride:

https://bitcointalk.org/index.php?topic=5315607.0


try this with my data and stride.... looks what will be work or not

hey bro... i had use z signature as the start range. it dont work on the keyhunt programme. its taking awhile.

Anyways, i saw some of you looking how to get the r,s,z signatures, you can just clone the program from here https://github.com/iceland2k14/rsz

check pm...

Replace data of base point is file

keyhunt/secp256k1$

this strings of base point data:(in this example I am already put data of my base pooint:

// Generator point and order
  G.x.SetBase16("a0d287fb17a25850106cc52227......
  G.y.SetBase16("4df036d34f3bdab912371941cc.......
  G.z.SetInt32(1);
  order.SetBase16


and use with stride


but, keyhunt bad work for me with stride,and I have no vast.ai account now for try stride with this software what has a good stride:

https://bitcointalk.org/index.php?topic=5315607.0


try this with my data and stride.... looks what will be work or not


Bro, if you have any qeschions - you are welcome.

p.s. i in my scrypt and your scrypt are equal !


Br

If I were to use
krashfire's code instead of your bsgs Is it also necessary to replace the base point? If you use the code provided by krashfire So what do I need to replace my base point with? Can you elaborate on that?
