The thing is that the "x" coordinate of #125 is: 33709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e; so I don't see how do you add "F" to 03 x coordinate of #125. Not only that, but if you switch "02" to "03" on a public key, you are talking about a very different privet key, so 0333709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e is no longer #125.

And BSGS don't use dp, it actually works in a sequential manner, deterministic, and not probabilistic like Kangaroo.

Thanks anyway man, but I think you should re-learn ECC, I can see you are confused on how it works.

Hello.
You apparently did not carefully read what @digaran wrote to you.
If you change #125 02 to 03, you will get the same private key as #125 but with a minus sign "-"!
The public key 0333709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e is also on the EC, but on the other hand.

For example, puzzle #65:
Private key: 00000000000000000000000000000000000000000000001a838b13505b26867
Public key: 0230210c23b1a047bc9bdbb13448e67deddc108946de6de639bcc75d47c0216b1b


Private key: fffffffffffffffffffffffffffffebaaedce6af48a03a1799ad57ca83d8da
Public key: 0330210c23b1a047bc9bdbb13448e67deddc108946de6de639bcc75d47c0216b1b

Now do you understand?

So If I have to start from a range on BSGS according to your mathematical calculations, which key is the closest that you almost thought could have hit puzzle 125... lets search within that range on BSGS. then we can all share some funds together too.

The closest one is 03ed01ff219ed5c1afc12d991a82e3063ddcee1fd53b46f7cad52a0d87a7112aed, it should be searched for in the 124 range.

You can't convert public keys to privet keys (at least not yet). What you can do is what BSGS do: try a privet key, convert that one to public key, and see if it match the public key you are looking for; if it don't match, try the next one, and so on.

There is a chain of lols in this page and previous one.
Don't let the looks of private keys deceive you.

This is N

FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141

Now in order to find the inverse of your private key, just subtract it from N and you will have negative x coordinate of your private key. You should know whenever you generate an address, you are actually generating 4 addresses which you could use, but only can control 2 addresses with your key unless you subtract the key from N to obtain -n of your private key.

In ECC, those large private keys are just negative numbers, till you reach the middle range, meaning half of all private keys are negatives, the other half are positives.

So, as I said earlier, in order to subtract a private key from your public key, it's best to switch x coordinate and also switching the x coordinate of the result because it would be -n and as you did yesterday, subtracting something from a -n key will actually add the 2 keys together, also adding to a -n key as I said will subtract from the +n version of your key.

You should use another calculator which shows, accepts public keys with 02 and 03, this way you won't get confused as to whether you are adding or subtracting.

Just stop lol. Read what he said. You can’t subtract a private key, a private key, from a public key. Yes, you have to convert the private key to a public key before subtracting it from another public key.

All those programs you are calling sissy, do math like you are doing.

You can just multiply G by any number in one go, adding or subtracting and I'm not talking about under the hood as you like to say, but manually you can just add 2 private keys directly to have a resulting public key, though you don't have to manually convert a private key into a public key and then try math operations on them.

Also, do kangaroo and BSGS do any division? If they are not, then they are useless, if they do then again they are useless because by dividing properly, you should find a key in a much much shorter period of time.

However I'm guessing kangaroo might do division but ECC doesn't bend so easily.

So If I have to start from a range on BSGS according to your mathematical calculations, which key is the closest that you almost thought could have hit puzzle 125... lets search within that range on BSGS. then we can all share some funds together too.

The closest one is 03ed01ff219ed5c1afc12d991a82e3063ddcee1fd53b46f7cad52a0d87a7112aed, it should be searched for in the 124 range.

This key you call the closest one could have a size half the 2^124.
I might be wrong but somehow I can say with 50% certainty that #125 starts with 0x1c. If I'm right it could help a lot in further lowering the bit range, this has taken me more than 45 days and I am still not sure.


Maybe, maybe one way to figure out if we are subtracting too much from #125, would be to start subtracting a bigger key and keep reducing it's size very carefully till we see a -n key as a result,  though because of this mod thingy it is extremely difficult to determine if the result is -n or not.

Chop chop guys, the rich and wealthy are about to use their silicon wares and grab our loot, we need to step up our game.😉

[GoldTiger69]

@digaran:

Man, this is the last I'm going to say about the subject: You are doing the calculations wrong, like alberto said and WP repeated to you, you can't do operations on public keys and privet keys at once, you can't mix them, they are not in the same context. One makes reference to the other, but they are not in the same category (excuse my writings, English is not my native language).

To prove my point, you should use any script that manages public keys/privet keys and you will realize that you are doing it wrong.

It's not criticizing, I just want you to advise that you are wasting your time doing that kind of operations.

Good luck, man.

Well, a few hours ago you didn't know -n and +n keys are one and the same, now you are saying I can't for example add "F" to "1" to reach "10"? (Hex)
But instead I need to add

If you are not using a decent calculator, you should find one. Because it makes your job a lot easier.

[Etar]

If you are not using a decent calculator, you should find one. Because it makes your job a lot easier.

You have "decent calculator" that is very smart and all calculations/convertions occur according to the rules that you were told about alberto and WP and other.
Between keys need to do scalar arithmetic. Between points - points arithmetic. And you can`t mix each other.
You say:

Subtract this
0302157655af8bb1decd37d161aa92cc7050cae1d6b4f44e4aa04507e3c1855159
From this
000000000000000000000000000000001e739ce739cf7bdef7bdef7bdef7be0c
To reach #125. (0233709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e)

Step by step what your calculator do:
1) 0302157655af8bb1decd37d161aa92cc7050cae1d6b4f44e4aa04507e3c1855159 convert to uncompressed format
x1: 02157655af8bb1decd37d161aa92cc7050cae1d6b4f44e4aa04507e3c1855159
y1: 321770ea8770a82e7e72072b47494ce33c4954afab21aa7197da3745db653467

2) seeing this 000000000000000000000000000000001e739ce739cf7bdef7bdef7bdef7be0c the calculator understands that this is not a point and converts it to a point:
x2: ece9f19985af4319e3fee74a6a522b2610150288233f14533fd28159d4891d89
y2: c94acb0ddfcf37af4dd687ad43ed9457338df8d5f7ef2b51dc148d9ac6bd516b

3) after that calculator do substruct (x3,y3)=(x2,y2)-(x1,y1), substruct mean addition but with negative y coordinate (x3,y3)=(x2,y2)+(x1,p-y1)
and the result
x3: 02210ba69dd8525b3fa3941a448efaaeef905753b40f66cd95669a166f0bb1d5
y3: 0838d4b0841472ee5d82ae62913557500987cbcb8024b10c4f6c4e40871aa837
it is correct result? No!
Because you say do substract but need doing addition:
(x3,y3)=(x2,y2)+(x1,y1)
and here is result:
x3: 33709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e
y3: 2a1c304a39a77775d3579d077b6ee5e4d26fd3ec36f52ad674a9b47fdd999c48
that is equl to 0233709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e
if this all operation doing in background of "decent calculator" it is not meaning that it shouldn't be done.

The thing is that the "x" coordinate of #125 is: 33709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e; so I don't see how do you add "F" to 03 x coordinate of #125. Not only that, but if you switch "02" to "03" on a public key, you are talking about a very different privet key, so 0333709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e is no longer #125.

Sorry man, but you are getting confuse:

On the second point you are talking about, what you are doing is subtracting PK #65 to N, and the result is:

Public key for second point = 0330210c23b1a047bc9bdbb13448e67deddc108946de6de639bcc75d47c0216b1b

PK #65 =/= PK second point

Your confusion strive on the fact that both points share the same x-coordinate, because one is the "reflection" of the other, but the PKs are not the same; and as you can see, none of them are "negatives". There are no negative numbers on ECC.

Good luck to you too, man.

You can just multiply G by any number in one go, adding or subtracting and I'm not talking about under the hood as you like to say, but manually you can just add 2 private keys directly to have a resulting public key, though you don't have to manually convert a private key into a public key and then try math operations on them.

Also, do kangaroo and BSGS do any division? If they are not, then they are useless, if they do then again they are useless because by dividing properly, you should find a key in a much much shorter period of time.

However I'm guessing kangaroo might do division but ECC doesn't bend so easily.

So If I have to start from a range on BSGS according to your mathematical calculations, which key is the closest that you almost thought could have hit puzzle 125... lets search within that range on BSGS. then we can all share some funds together too.

The closest one is 03ed01ff219ed5c1afc12d991a82e3063ddcee1fd53b46f7cad52a0d87a7112aed, it should be searched for in the 124 range.

This key you call the closest one could have a size half the 2^124.
I might be wrong but somehow I can say with 50% certainty that #125 starts with 0x1c. If I'm right it could help a lot in further lowering the bit range, this has taken me more than 45 days and I am still not sure.


Maybe, maybe one way to figure out if we are subtracting too much from #125, would be to start subtracting a bigger key and keep reducing it's size very carefully till we see a -n key as a result,  though because of this mod thingy it is extremely difficult to determine if the result is -n or not.

Chop chop guys, the rich and wealthy are about to use their silicon wares and grab our loot, we need to step up our game.😉

You really need to understand EC keys converted to private keys. How it is not reversible without a massive amount of computing power. Power that we don't have today, with even just the public key. The public key is hashed from the EC key and is not very simply hashed back to EC. From that hash the address is created. The hash will be completely different if 1 digit is changed. Sure if you have the EC key its easy. This is why Bitcoin is secure. 1 way conversion to a public key that cannot be converted back to a private key, the private key is derived from the base EC key.

We are trying the find the EC key that has been put into reach because of the ton of zero's in front of the EC key, making the operation simpler but still difficuilt.

If you want to play around with EC keys and double hashing for keys read up and run libbitcoin tools. BX will be eye opening.

That was just one example showing compressed and uncompressed public keys being converted to addresses.

New information, investigate it to find #125, God willing.

Subtract this from #125 (you should convert it to whatever your calculator accepts, note, if #125 public key is e.g. 125 and the below key is 5, I don't mean to subtract 5 from 125, that could result invalid public key, so do subtract the public key of the key I gave you from #125 public key)

Then tell me what you see.

Is this what you see?

Now

Subtract this from 2^125

The relation of above keys with #125 is the same relation of #125 and 2^125.

If you managed to solve #125, I'd like half of it, thanks.😉

Still doesn't prove anything important that is needed to crack puzzle #125.

What have you done now? Did you compress the public key to a smaller range? it could be invalid public key

 don't understand how you think it's easy to get #125 even though its more tougher than pzzle 66 from my own point of view.

What do you mean by invalid public key? Whatever you put into elliptic curve it will give you a valid result no matter what, the only number I found that will never give any result is adding or subtracting N itself to or from any key.

You could add 2^512 to a random key and yet have a valid result, it depends on the implementation you are using.

What I am trying to do has nothing to do with brute force, solving DLP or anything similar, I just add and subtract, because public keys are just representations of numbers, and we could reduce numbers by simple subtraction operation.

[GR Sasa]

Yes but you are way far more from solving #125 this way than you think.

Do you know that ?

EDIT: And also goodluck with prime numbers
