start with 79B

Why does everyone keep trying to solve it?

I think this is a game that benefits others, not the solvers!! When more inventory was added to these puzzles, each Bitcoin was worth about $27,000. Have any of you thought about why the finder of puzzle 69 lost inventory?

Let me remind you of a few principles: Bitcoin can only consider a transaction as completed after receiving 6 confirmations in the next blocks in the blockchain network chain, and before 6 confirmations, that asset is not in your possession, and the block containing the transaction confirmed by miners may be completely removed from the blockchain chain before reaching 6 confirmations, which are called orphan blocks.

lost because he used the mempool instead of Mara. Big mistake when it's already been discussed here on how to avoid losing those funds.

Although using a private mining pool instead of a public one can prevent RBF, but who can guarantee that the private mining pool will not embezzle the money? This is not difficult at all technically.
Normal transfers with high fees may still have a chance of success, but if they cheat through a private mining pool, you will never get your property back. I think the decentralization of Bitcoin does not allow you to hand over transactions to private mining pools.
And I have not seen any evidence that No. 67 and 68 were successfully transferred through Mara.

If you have any questions, why dont you try Mara by yourself? Ill make myself clear: im not specialist in bitcoin not even in coding. But I already have tested Mara and it`ll worked out in the end. At no time in this process the private key is revealed, you only need a hex of a signed transaction which contains just numbers, and past it in Mara. I dont see how they could get the private key and trick you leaving you with nothing. I could be talking bullshit since im not an expert about all of this, Im just talking about what I did and tested with 5 dolars.

If I'm not thinking incorrectly, the assumption or theory behind not trusting MARA is entirely based on the hex of a signed transaction, the idea that someone there, whether it's the miner or someone else, could access the public key information before anyone else and, thinking "well, this is a Bitcoin puzzle anyway," could take the entire amount for themselves.

There only 2 way. Collusion inside 😅. Or setup huge mount of miner at mara pool and hope lucky the public key pass to your miner ..

But why .. .. better to find way to solve it 🙃😅

If it fail trough mara , then mara reputation will fall i think. Cause the solver will surely go bonker 🙃

My discussion is not about attacking or removing confirmed blocks for profit; it is about why some puzzles - whose existence is recorded at the time of their creation - become very valuable and popular, but when these puzzles are solved, the rewards are not distributed to the solvers and are stolen? The answer is quite clear: we all know that it is completely ridiculous and illogical to believe that bots can obtain the private key in a very short time, given the public key. The only logical and 100% probable case is that those bots already have that key before you yourself have access to your private key. "Yes, of course the number of these bots is the same as the number of puzzles left. These bots all have the keys to the puzzles and are designed to monitor and investigate unsolved Bitcoin puzzles and monitor Bitcoin transactions across the blockchain. If you have access to a full node on the Bitcoin network, you can examine the transactions associated with orphaned blocks at the time and date of previous puzzle solutions and see how many of these thefts occurred there."

I'm writing this without being lazy and explaining it step by step: "completely ridiculous and illogical to believe that bots can obtain the private key in a very short time" might be true for keys over 80 bits, but what you said is nonsense for the following reason.

If we talk about the current puzzle 71, when you search for the public key of any 71-bit address using RetiredCoder's kangaroo, Ok I can even give you the hardware an RTX 4090 and as an example, I show below exactly how it works:

Ah wait, I reached the private key in 3 seconds. Even if I don't know any coding, I would automate this with AI. I did this for you without being lazy, and as I said before, please read the thread carefully starting from page 350s, even from 300s or much earlier.

This does seem a bit scary, and normal transfers may indeed be robbed. But my question is, who can guarantee that private mining pools will not be selfish and steal your property? If you submit the transaction data to a private mining pool, they have more time to crack your transaction.

If you transfer money normally and use the highest handling fee, miners all over the world will rush to confirm your transaction, and it may only take a minute or even tens of seconds to confirm your transaction. You still have a certain chance to successfully transfer money. This is also the benefit of Bitcoin decentralization.

But if you submit the transaction to a mara or any other private mining pool that came out of nowhere (sorry, I don’t mean it in a derogatory way) , wouldn’t you be afraid that they will embezzle your property? This does not conform to the decentralized principle of Bitcoin.

Maybe I don’t understand, but if I really crack the Puzzle 71, I will be very cautious.

I understand why you're scared I’d be hesitant too. But if you wait for mining by setting a high fee, someone else's bot can simply offer an even higher fee than yours, and this will go on until you run out of money. Unfortunately, disabling RBF doesn't really help.

As far as I remember, the fee strategy was already tested in earlier pages those who did the testing could give a clearer answer on that.
Rather than going through all that, I’d trust MARA. From what I’ve seen, it’s not just a “Hey, I have a mining rig, can I join your pool?” kind of pool. it’s a holding company. I’d take my chances with them.

Puzzles 67 and 68 were mined with MARAPool you can check it on Mempool. That alone is enough for me. And even though that's the case, what you said could still happen. I'm not a representative of any company or anything like that, but instead of a fee war, I’d rather take my chances with something that has worked before.

I think I couldn't express my point clearly! What I mean is that for example: If I pose a puzzle and anyone who finds the key can take the balance inside it as a reward and if the balance is 10 bitcoins, how can I be sure that no one can take the architect's balance? Even if he solves it? I will design a robot and give it the architect's private key and whenever the robot sees the relevant transaction in the network or blocks, it will transfer it to the given address with a high fee or delete the block,
