I don't know, maybe I'm wrong, but what I noticed is that your transaction was not broadcast from the Mempool route. I think you know a way.
The history here has two networks, one is the main one and the other is the main Mempool route, the transaction was not confirmed on the Mempool route, although it was sent earlier, but it was not approved, and maybe the Mempool policy behaved like this. but your transaction did not pass through the Mempol route, am I wrong? ?
https://blockchair.com/bitcoin/address/197kFKvMHoRJPXktc8xJwMjeTuE9xijBQ

After this experiment, I realized that the wallet  software "Electrum"  cannot grab the BTC of #66

we must  create own RawTX  (raw_hex)

use API broadcasts to blockchain

response = requests.post(
    'https://blockchain.info/pushtx',
    data={'tx': raw_tx}
)
print(response.text)



They've made opt-in Replace-By-Fee (RBF) the default in Electrum version 4.4.0. If you want to use the old version without this feature by default, you can install version 4.3.0 using the following steps:


git clone https://github.com/spesmilo/electrum.git
cd electrum/
git checkout 4.3.0
pip3 install -r contrib/deterministic-build/requirements.txt
pip3 install .

You can use old version of Electrum but every transaction will automatically have RBF enabled on the node.
Only option is to change node in Electrum to your own full-RBF-disabled node.
And mine in secret this transaction.

However, once the transaction is broadcasted using any (API) method, it is at risk of being replaced.

Even if you share it privately with a third-party miner, that miner could still replace it..

I reached out to major mining pools, and they told me they can't confirm a transaction without it going through the mempool! The pool operators will take the entire reward for themselves, they’ve known about this for a while and are just waiting for it! I don’t even know what to do in this situation... It's frustrating.

Hello everyone! I found the key to puzzle 66, but now I have another problem: how to withdraw the funds so that no one can intercept them with a bot? Please repost this message so the creator sees it! Maybe someone can tweet this so that the owners of large pools can respond, whether they can add the transaction to the next block when it is found, without broadcasting it to the network?
Pls, HELP ME!!!!!



What happened, you claimed to have found the puzzle? Why haven't you shot it yet?
Because you didn't find it, right?
You are trolling people 😅
Puzzle 66 is very difficult to find, you are not this lucky person either.

Oh my God! Whoever thinks I'm just seeking attention is way too full of themselves! Who needs fame from a bunch of idiots? I wasn't addressing you, but rather people like pool operators, software creators, and other professionals, and ultimately, the puzzle creator! I'm ready to provide any evidence to the puzzle creator!

Find a major miner here who is willing to purchase the private key from you. Conduct this transaction in a public setting to guarantee transparency and prevent possible fraud.Good luck...


I need some advice on how to publicly conduct a transaction. How can I safely hand over the key and ensure I get paid at the right moment? Any ideas on this?

You should first mix the private key and a secret message together, then post the SHA-256 hash of that combination here. For example, if your private key in hex format is '36b0f7381163cd38c' and your secret message is 'helloitsme123xyz', you should post the SHA-256 hash of the concatenated string here immediately.


This sounds very unsafety...

What kind of insecurity are you feeling? Do you really think that someone can crack the SHA-256 hash created from the combination of your 17-character hex private key and an extended message with no character limit, which can include numbers, symbols, and alphabets ranging from 10, 15, 50, or even 100 characters? If so, that's quite laughable. Let me tell you that it won't just be a hash; it will be proof that after the creator, you were the only person who knew the private key. Many have come and gone, claiming to have solved Puzzle 66, and maybe you're one of them. The sooner you post some proof, the better it will be. There is no method more secure and easier than this, You asked, so I told you. The rest is your own wish..

better for whom? for bot owners? they will become more wary, especially since I don’t have much knowledge of cryptography to encrypt my private key and post it here! no need to prove, just help me contact the miners! or let the creator pay attention to the problem of funds being stolen by bots from under the noses of those who actually found the key!

MergeWork: destination argument missing = you are missing the 3rd argument.

If you are trying to merge 2 different work files, you have to tell it what to save it as; merge file1 file2 file3 = merge file1 and file2 and save it as file3
after merge result file have 15mb, but! work file 6gb each other

All programs from JLP are perfectly optimized and if it were possible to improve the result, then the author would definitely do it.

To "double the speed" there is only one solution.
This is to use not only the addition of the kangaroo jump, but also the subtraction.
This will not require many resources, but will double the number of tested points and thus the number of  distinguished points.
But it will also slow down the progress of all kangaroos.
Can this help, maybe, or maybe it will just overload the hash table with extra distinguished points.
With this modification also need to turn off the check for dead kangaroos, because a kangaroo hitting the same position that was left
after the subtraction does not mean that the kangaroo is following the trail of another kangaroo.
But as i said above, the author would have done it if it had worked.
Im agree with you! I just wanna know how much speed kangaroo have with 4090 in Stock WO powerlimit..May be I doing something wrong but my speed on 4090 nearly Tesla V100 32Gb  1420 MKey/sec speeds



Out the box, non modded Kangaroo with 128x128 grid size. Should be in the 2200-2300 range.
how much size have work file saved by 4090?

 Perhaps you have a modified kangaroo? what settings did you use to achieve this speed?

Yes, I modified the Kangaroo code.
Then what's the point of talking about the speed of the modified program? I can also set a multiplier of 2 or 3 in the speed test section to get the speed that I would like to see...duddde
What's the point of talking or asking questions at all on here? It appears you are shady if you would set something you would like to see, just to report it...duddde
Shady's here is your proposal to mine for you a puzzle in pool with your "modified" super program with 4x speed)))

  Results of RTX4090 is something of beautiful ! But, what do you mean when you say 7.7 Gkey/s?

Because what I understand is that you anaylize and execute 7.7 Ghash/sec of ripemd160(sha256(publickeycompressed(privatekey)), is it right?

No, I wish we could get that speed, then #66 would be in reach!

Remember, in Kangaroo, we are looking for distinguished points of the x point. So to keep it simple, it’s publickey(privatekey) and check for x amount of trailing distinguished points (could be leading DPs as well).
The more complicated are the jumps but really it’s a set stride(s) that all Kangaroos follow…a path of sorts, until a wild one lands on a tame one.

The wilds require one extra calculation but it’s either one more step of adding or subtracting, based on your version of Kangaroo.


how much realy speed rtx 4090 Kangaroo?
Real speed was posted. 7.7 GKey/s, for a single RTX 4090.

I always like numbers!
First, what is this modified kangaroo program?
Verified that a 3090 gets 4.8G Key/s

This is not JeanLucPons version of Kangaroo
this have a lot of unnecessary checks that slow down the process.

The plain cuda version of secp256k1 and several optimize changes have this speed.

RTX 3070 with power limit 170w 2.4 GKey/s  GPU Ram Usage 3.5GB
RTX 3090 with power limit 350w 4.8 GKey/s  GPU Ram Usage 8.0GB

And one dedicated server for check
have 32GB RAM ( 8gb+ ram need for bloom filters )
~140Gb of nvme used for kvrocks storage for store 2^31.10 of DP32
or 35Gb if use DP34

ps4all. Possibly I'll find time for compare if you have dp's (or work file fromJeanLucPons Kangaroo ) for still determine 120 and check wild/tame and later
(in compared dp's included buyed from zielar)

But i rarely come here.
how can you compare that to the speed of a kangaroo? it's a different program
