Shooters Shoot...

While running some performance tests with Rotor-Cuda I've noticed that when I assign a monstruous grid-size for my GPU, I can get more speed.

If I set it like this --gpux 18000,512 I get a steady 4.62 GK/s peaking at 6.90 GK/s for a few seconds.

Can this cause any problems, like skipping keys during the search? If so, can anyone recommend a good grid-size for a 3080ti?

Thanks in advance!

The best thing to do is to test your grid size and run through a small range, something like a 2^40 range. See if the grid size finds the key or not.

I use a similiar version of KeyHunt Cuda / Rotor and haven't missed a key with a large grid size. But seriously, run a simple test to know for sure with your card and setup.

Does anyone have concerns about the advancement of machine learning algorithms becoming increasingly capable of breaking complex encryption methods, such as secp256k1 and others?

What is secp256k1 encryption methods? elliptic curve doesn't encrypt anything, it's just a numbering system with 2 sides, negative and positive.

Here is an example of how it is possible to "break" the key :
Imagine this is your private key :
368812095337 and this is your public key:
023eb3a5c5c9e1303055215b2f2f455288bda053e1791a2b06d2c385cbc94eb51a

Now imagine you have zero knowledge about private key, can you or AI tell us how we can reduce the size of private key down to 368812 without even knowing the actual key above? If you guys can do that, I'd be concerned.

Start range :
0000000000000000000000000000000000000000000000020000000000000000
End range:
0000000000000000000000000000000000000000000000040000000000000000 -1

Both of them show the range correctly, where do you see anything wrong? Anyways the correct range for all keys are in the second post.

Hmm why is the keyspace shown different here on the first site, this site https://privatekeys.pw/puzzles/bitcoin-puzzle-tx and this site https://privatekeyfinder.io/bitcoin-puzzle/.

Grin

end will be, the puzzles are in the wrong keyspace, thats why nobody can find anything. Look at 66 for example, different keyranges.

unfortunately, there is a possibility of missing the desired value.

That said all no? The possibility of missing the target value with bigger keys is great.

many test was. real steps to find was different.
22-bit at this test is:
1011011110010000001111 777854
but anyway its better vs range(2**21, 2**22-1)

Lets say this is a private key, 3857991093436143 and you only know it starts with 3, that's all. Now that you have no other knowledge about the key other than what it starts with, can you give us a %100 working method to reduce the size of that key and still finding it successfully?

If you can do that, congratulations because you just partially broke elliptic curve.

found a way to reduce 1/6 total range.
python proto give a nice result for all known PK.

That is only passible when you know the private key, but WITHOUT the private key all those reductions aren't possible.

it's wrong.
for example 7-bit key can be found at 4 step (direct search from 2^6 to (2^7)-1 will find only at step 12, reduce 3 times).
1001001 1
1001010 2
1001011 3
1001100 4
result: KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU7hDgvu64y

17-bit at 17318 (direct at 30287 step, reduce ~2 times)
10111011001001111 17318
result: KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFiHkRsp99uC

22-bit (direct 910351)
1011011110010000001111 607024
result: KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rP9Ja2dhtxoh

and so on... tested with known PK.
but still at researching.
8-bit key skiped by this method, therefore, unfortunately, there is a possibility of missing the desired value.

i was wrong about 1/6 (error with calculation was), anyway reduce are possible, but with chance to skip needed value =(
and we must take into account that by skipping some values when generating numbers, we save time on generating the address and checking it with the required one (speedup).

hope CUDA version will be a nice with 66..70 profit.

good luck!

Hi, who are you talking to, do you need someone help you cross the street? 😂

Since you cared enough to share your achievement verbally, could you be kind and tell us how did you managed to reduce the range for an unknown key? You know sharing is caring right? But if you found a way to do range reduction for public keys, let us know about it, we might find some useful hints.😉

Hi a maybe noob question here, is

[4659.96 TeraKeys/s][Kang 10240][Count 2^26.82/2^29.07][Elapsed 02s][Dead 0][RAM 15.5MB/45.1MB]

a good speed or is it a bad speed on Kangaroo, i can't find a post where a number is given, what's good and what's bad.

This is only with 7 ncore in use no GPU. CPU use 58%.

If somebody has range of good bad, would be fine.

Yep i think somebody has the controll over the Puzzle, not all existing Bitcoin PK maybe i wrote this wrong.

I would never cause a chain reaction on anything, sharing is caring, but when somebody got the luck, to find a OLD COIN, even on the grasfield with a metal detector, or on the webfield with a PK detector, i think it's the same, take it be happy. ( Don't tell me you would let a OLD COIN in the Grass, if you find one, same for BTC, you let it in a weak wallet on a weak address, plz don't cry if somebody find it ! )

And if you ask me why, "if you care about your OLD COINS, you will hold em in the best and securest possible way ( cold wallet, transfer to segwit ... ),why because it's your darling

Alright, I remember watching a documentary about some tribes in Africa, 2 or 3 men with nothing but wooden sticks track down lions when they hunt and after scaring the lions, they would take the hunt and go back to the village, I call them the real men with some balls. 😂
Sure you can find any puzzle key and grab the coins, but remember any other key if touched, the fire breathing dragon will wake up, then no amount of balls could save you from that dragon.😉, I'm using analogy to convey the message.
Btw, sending to segwit addresses does not add to the security of your coins.

but if you don't care about it .... sorry !!

And why be scared or live in fear if you find some, nobody wanna be the most hated and hunted, nobody need furniture from the last tree, in a small village in Africa, that has be the only shadow giver there.
Only to have something what nobody else has.

Remember the Reused R Value and some good Samaritan here, be normal to gain respect, stay on the ground and remember what could be if .... And your life will be great !

Ok let me stop you right there, you really think someone has the keys to all funded addresses? That's not true, all the private keys (funded keys generated by secure wallets) have 78 digits, you would need to brute force at least 2^128 keys to find all the used addresses.

Even if there is something to hunt, it should be the puzzle keys alone, they are the ones we can grab for our own, anything else is for people, taking them equals to either prison or flying with some angry angel towards hell. 😅

Now even if you find a way to access any key you want, why would you cause a chain reaction of distrust and crash the whole market? You just take a few puzzles and live without any fear, but if you lose control to your greed, that's when lions find you alone in a dark place, and believe me, nobody wants to find out what happens after that.😉

Hyenas are the smiling animals ( Many hyenas make the king lion sweat ) Grin

, i mean puzzle 75 my fault.

Look at puzzle 74 nothing happend long time, no pubkey was known, and then a txid was made at 4 am, and at 23 pm it was cleand. Happend often when you look at it.

Well puzzle 74 was never cleaned, but I know what you mean, you want to for example watch the blockchain if puzzle 66 moves, you can grab the public key then use kangaroo to quickly find it's key and double spend it with a higher fee, like the way of hyenas. Well, I guess these woods need all sorts of animals you know? 😉🤣

What I don't understand, is trying to use an API to get millions of keys from blockchain, why so many? You just need a few.

No i think it will maybe happens, that the creator ( funny like the movie Grin

) of the puzzle one day think, damn i should give them a bit hope and make a txid so the pubkey can be anallyzed Grin

, because it's getting boring for all when long time nothing happens. Same for some other addresses.

And i see it as a treasure hunt, all the over 10 Years old addresses, that have never be used ( lost pk, owner died, like i write in a post, i lost pk also ), free for hunt, maybe some see it ethnical different, but when people walk with the detector in the forest and search for things, nobody care if they found a bag of gold, or a old " COIN ". My detector is my PC ! And thoose who care about their " OLD COINS ", will move them to a safer address.
