Hello, I noticed something.

66. Wallet transfer time: 9/13/2024, 01:59:39
Your message: 09/13/2024, 01:57:12

I guess you found the wallet?
Why haven't you had any messages since you became a member in January 2024?
It's very interesting, I was curious about your hardware and what software did you use? (Unless you're the creator, of course?)

I wish it was me but unfortunately not. I was part of the 66bit pool trying to find the key but we lost it. The hex private key was posted in telegram. All I did was input the hex key into a python script that spits out all the address info.
I am more of a reader than writer so I never posted before.

How would the real extended public key become known?
If you have enough keys, and you know, that they are all coming from the same wallet, then you can try to retrieve the master public key, and later, the master private key. However, it seems to be not this one, which was shared, because it contains only the key to puzzle 66 (not to all puzzles).

Why zpub and why BIP84 key derivation?
Because it is written in this particular key. But it does not mean, that it is the same, which was used in the puzzle. It can only be used as a hint, to determine, which tools were used by the author of this post.

To my knowledge BIP84 derivation is for P2WPKH, ie. native Segwit addresses which aren't used in this puzzle.
Well, Bitcoin Core can sometimes give you P2PKH, and sometimes P2WPKH. It is possible, that a single master key, will give you different address types in different wallets. For example, you can see P2WPKH in Bitcoin Core, and iancoleman tool can give you P2PKH instead.

So what's the purpose of a half-baked extended public key when it's incomplete?
Some wallets can only load descriptors, or master keys, and in this case, you can write a single key in a "master key format".

So, to sum up: I thought that the author of the post somehow got the master key, but it seems to contain only that single key, but just written in yet another format, to be loadable by some specific wallets.

This is the extended public key. ...
How would the real extended public key become known? I don't see a feasible way.


Yes, I know it is zpub. I know it uses BIP84 key derivation for P2PKH addresses. I know it contains 024ee2be2d4e9f92d2f5a4a03058617dc45befe22938feed5b7a6b7282dd74cbdd public key, double SHA-256 checksum, equal to 0xb968b15d, and some other information, which you can see in hex. However, the chain code, and some other information is still missing.

However, the chain code, and some other information is still missing.

And also, even if you can figure it out, then you probably won't derive the key from the puzzle, but the "non-truncated key" instead. Which means, that you will get hard, 256-bit keys, where only some N bits would match the puzzle. But there could still be enough non-zero bits, to make breaking it quite hard, if you try this method.

And also note, that by breaking this single key, you could reach extended private key, and then access the whole wallet.

What is that supposed to be?
This is the extended public key. I didn't verify it yet, but if it is valid, then by knowing this key, you could potentially derive all public keys from the puzzle. And if that would be confirmed, then someone could sweep all unsolved keys, up to the 125-bit public key.

Hi

1) Suppose I find pvk for puzzle #64
2) I import the bitcoin address 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN
3) I start a full fund transfer to another wallet
4) My transaction shows up in the blockchain (showing number of confirmations)
5) Once my transaction has been launched, the publickey is then visible.

My question is as follow:
Is it possible for someone using "Pollard's kangaroo ECDLP solver" to find the private key fast enough to be able to import the same address 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN and then launch  a fund transfer
 to a different wallet ? (before enough confirmation on my transaction and of course pay more gas fees than me)   

Huh

If (hypothetically) you found the private key for puzzle 66, and simply tried to spend puzzle 66's BTC balance to another wallet that you control, you better hope that that transaction gets mined into the next block
within a few seconds, or it will be stolen with 100% certainty. This is also the case for the next few puzzles, 67,68,69...

The only way to do that is by using the MARA Pool Slipstream. The transaction will be mined before the public key enters the mempool.

It won't actually be seen at all through the mempool.

Interesting, as I'm not in the key hunting business, I didn't know about https://slipstream.mara.com/ yet. Thanks for pointing me to it. They seem to charge about double the current fee level (as of writing this post mempool.space indicated 5 sat/vB and Slipstream asks for a minimum fee of 10 sat/vB; I expected worse).

I've read their ToS briefly and it seems at first glance that indeed they claim your submitted transaction remains "confidential" until mined into a block by their own pool.

One can only hope that slipstream.mara.com are really honest and do not exploit the internal disclosure of the public key themselves. I heard that mara.com does attract some critisism, at minimum as far as I recognized for censoring certain transactions which got tagged as "not appropriate". Can't say anything how reliable they are when at minimum 6.6BTC are at stake.

WP did a test with slipstream and it didn't leak the public key to the mempool for the bots to intercept, so it seems like they mean what they say. As far as Mara not mining some transactions, it MIGHT have something to do with them being a publicly traded US based company subject to the Dept. of Treasury's Office of Foreign Asset Control (OFAC) regulations. OFAC maintains a list of "sanctioned" wallet addresses that they don't like, and if you're a US person / company and you interact with one of these sanctioned wallets (including mining a block which spends funds from a sanctioned wallet) then you can expect up to a $1M fine and 20 years jail time. https://ofac.treasury.gov/media/8551/download?inline

I don't understand people that setup multi-tens of GB stuff via BSGS to crack it in minutes, it makes no sense. Keep it simple.

Some people don't have GPU, some of them don't even know what they are doing

Do you know how the previous solver of puzzle 64 claimed his reward with just transaction fee of BTC 0.00063 while MARA isn't available yet and there also exists of bots out there back then?

Because most likely it wasn't worth it to set up bots since the reward was relatively small, so no one really cared.

Puzzle 66 can be cracked in less than 0.5 seconds (500 milliseconds) once the pubkey is revealed. One only needs a modest setup for that as well: a database of precomputed Tame DPs (less than a couple of GB, can be preloaded in RAM) and a low-budget GPU with a fast-returning execution kernel to find a couple of Wild DPs. Match with a Tame DP is basically instant. I don't understand people that setup multi-tens of GB stuff via BSGS to crack it in minutes, it makes no sense. Keep it simple.

Anything over 10K $ is a good motivation for bots!

Puzzle 66 can be cracked in less than 0.5 seconds (500 milliseconds) once the pubkey is revealed. One only needs a modest setup for that as well: a database of precomputed Tame DPs (less than a couple of GB, can be preloaded in RAM) and a low-budget GPU with a fast-returning execution kernel to find a couple of Wild DPs. Match with a Tame DP is basically instant. I don't understand people that setup multi-tens of GB stuff via BSGS to crack it in minutes, it makes no sense. Keep it simple.

It is a lose-lose example in my case the bot will keep increment 1sat/vB more than your or anyone else TX.

In the final round in case to reach the limit of the input balance it will append an extra input to the TX and send 100% of the puzzle address as fee.

There are so many bots set up running hunting for the public key of 66. Wouldn't it already be the case where each of the bot will keep appending an extra input to the TX till it reaches 100% of the reward as a fee?   



The only way to do that is by using the MARA Pool Slipstream. The transaction will be mined before the public key enters the mempool.

It won't actually be seen at all through the mempool.

If (hypothetically) you found the private key for puzzle 66, and simply tried to spend puzzle 66's BTC balance to another wallet that you control, you better hope that that transaction gets mined into the next block
within a few seconds, or it will be stolen with 100% certainty. This is also the case for the next few puzzles, 67,68,69...

Interesting, as I'm not in the key hunting business, I didn't know about https://slipstream.mara.com/ yet. Thanks for pointing me to it. They seem to charge about double the current fee level (as of writing this post mempool.space indicated 5 sat/vB and Slipstream asks for a minimum fee of 10 sat/vB; I expected worse).

I've read their ToS briefly and it seems at first glance that indeed they claim your submitted transaction remains "confidential" until mined into a block by their own pool.

One can only hope that slipstream.mara.com are really honest and do not exploit the internal disclosure of the public key themselves. I heard that mara.com does attract some critisism, at minimum as far as I recognized for censoring certain transactions which got tagged as "not appropriate". Can't say anything how reliable they are when at minimum 6.6BTC are at stake.

Yes. And they tell me that I am hallucinating that this is possible...  Grin

So, has anyone figured out a bulletproof way to spend puzzle 66's inputs, once the key is found, without the internet-of-bots stealing the prize? Other than trying to find a big enough mining pool that will mine your transaction into a block and not expose the transaction to the mempool? Could any mining pool even be trusted to that extent?

I cant belive that I read this BS again on this forum. Are you out of your mind? Why the hell do you need a mining pool?HuhHuhHuh
I have read a similar BS from another user in another topic, that is talking about miners.

You dont need any miners to get the money, when you got the privatekey, you can immediately take control of the bitcoins. Do you really dont know how?



 It's a blast to solve Puzzle 65, 66, 67, 68.  It takes about 60 seconds once we identify the public key from the blockchain.

and the time required to import the key into Electrum and start the redirection of transactions (if they exist ).

The 10 minutes is the average time and this is a pretty stupid circumstance. At this stage, the transaction has
entered the mempool and remains 'Pending,' waiting for confirmation.

It only takes a matter of seconds (for such a small range) to obtain the private key from public key, after which
you (or a thousand of them) can replace the still-unconfirmed transaction in the mempool.  

In other words, you need a very strong miner to speed up (prioritize) the transaction to go through the mempool in
one (or less than) minute for puzzle 66, 67, 68, 69.

Are you replying to me, or just randomly hallucinating? What is the purpose of your writing?
