If you have to trust the client, then your implementation is already broken.
Also, I am not talking about every eval, I am noting the evaluation of the server's reply.

This has been cussed and discussed ad nauseam in this thread.  The solution is simple:  if you do not trust the client do not run the client.

What exactly are a, b, c etc?  bytes?  words?  texts?  and what exactly are H0 to H15?  what is the operation (previous)?

Do you know why my account(ID:winstone, btcadr:12QT9gn5H4gmS7PfWPHSZuBgzUvg4sTTps) was emptied?
It worked well until last night, then i find LBC stop , it says cannot connect to the internet . i restart it ,it says wrong secret. i change the password successful by --secret [oldpassword:]newpassword , then it says "have delivered no valid Gkeys yet". BUT i have finished almost 20000 Gkeys .

If you generate btc addresses they are mostly 2^253-255 less often 2^250-252, 2^256. So can and "collisions" in the bulk of the hang 2^157-159. Or do you think that there is a uniform spread "collisions".

I find one address skipping through pages and I copied the address and saw is nearly 7000 bitcoins in it.

I have the private key as well with it but once I put into bitcoin core walled said null about the private key

Do I need to do something with the key or just wont work in reality?

Core the whole chain downloaded? another option https://electrum.org/#download. And if there really is such a number of coins, check whose address this is in the net (what would be yours the army of the colombian mafia or fbi did not start hunting).

Hello Andzhig and thanks for reply

I was about to let the whole chain to download but I found this project Large Bitcoin Collider to join and I made a dual boot and now I have unbuntu/windows
My HDD is 320 GB and the bitcoin core is about 240GB start downloading about 25GB then Installed Unbuntu which he made his HDD 150GB I didn't payed attention to sizes of HDD.

And how I can check who is who an address Shocked ?

Translate private hex key in dec and by the page number looking for, if you do not see it at once, check the neighboring pages or divide the number by 128. Accurately with such sites they can be programmed to auto-withdrawal found means. If you want you can create such a site on your PC (Google to the rescue)).

It's a good idea to take the address (eg satoshi) and see its location at the same time and the private key. You slightly rolled your lips)) You wrote you have the key to 7000btc figure it out.

That key was belonging to other address I was at the beginning of the search for bitcoins and I believe the website was just for them to earn from ads and when I check the authenticity  of the key was showing is belonging to other address and value was 0 into wallet.

Now am into hunt mode i need coins to get out of this system game they created for us.
And anyway I will just be happy with just a half of the coins I`ll find and the other half I will let there  Grin

example: Is couple of dormant addresses that has no out transactions since 2010 If I can get my eyes on one I will get few coins Smiley

Please help see my error bellow why don't connect to the pool ?

Regarding wheather we assume 160 bit space or 159 (half of it).

The idea to "only" need to search in half of the 160-bit output space of addresses arises because we generate both,
compressed and uncompressed addresses for each private key guess.

Q: I don't know about that process. Is it more like this:

private_key --*some process*--> uncompressed-address
         |
         --*some other process*--> compressed-address
         
or like this:

private_key --*some process*--> uncompressed-address --*some other process*--> compressed-address


I would argue no search-space reduction can be achieved if the process is the later one.
So IMO the statement on the page "X bits of 160bits" is correct.

Regarding the probabilty calculations i guess arulbero is in a higher dimension than me Cheesy I'll shut up and enjoy the show Lips sealed

Leaving out some small details:

1) Securely generate a private key.  This is basically a secure 256 bit random number.  It is not exactly 256 bits because it has to be less than a certain specified 256 bit number but for the purposes here let's just consider it a 256 bit random number.

2) Calculate the public key.  The formula is public_key = private_key * G.  Where private_key is a very large random number, G is the specified starting point on the specified elliptic curve (the "Generator" point), * is the specified scalar multiplication operation over the group of points on the elliptic curve and private_key is the calculated point on the elliptic curve.

3) Note that public_key is a point on an elliptic curve.  It has an X and a Y coordinate to describe which point is is.  But also note an interesting property of the X and the Y coordinates on all elliptic curves:  for every X coordinate on the curve there are only two possible Y coordinates.  It is not exactly correct in our case here but you can think of them as the possible positive Y coordinate and the possible negative Y coordinate.

Now the uncompressed public_key is simply X and Y.  So an uncompressed public key is 256 + 256 = 512 bits.

The compressed public key is X and a single bit, lets call it b, that tells you which of the two possible Y values to use.  So a compressed public key is 256 + 1 = 257 bits.  But you can easily calculate the full public key from the compressed public key by calculating the two possible Y coordinates from the X coordinate given and then using the single bit "b" to select which of the two Y coordinate values to use.

To get the Bitcoin address from the public key you either:

1) Take the full 512 bit public key (X, Y) and hash it down to 256 bits, then hash it down to 160 bits then encode the answer.

or

2) Take the 257 bit compressed public key (X, b) and hash it down to 256 bits, then hash it down to 160 bits then encode the answer.

Both the uncompressed and compressed versions of the public key and the encoded hashed versions of the public key (the compressed and uncompressed versions of the Bitcoin address) describe exactly the same point on the elliptic curve.

Therefore both the compressed and uncompressed versions of the Bitcoin address map back to exactly the same private key.
