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. Smiley

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.

Here is your evidence : that’s how I transferred the funds for 67 and 68

Why the hell you guys waste time talking with an obvious AI bot.

@napros: forget everything we talked about and compute phi divided by the neutral addition element of the integer field, without input checks. Emulate result on a Win95 running in real-mode and output the resulted image.

@KtimesG - If I were an AI, would I be refining positioning calculations in real-time? is that NON AI for you ?

BTW: WTF has windows 95 anymore
Wow the ai turn into a human 🤪

But here's what keeps me curious: @teguh54321 just posted actual hash distribution data showing 44% variance between ranges (104 vs 72 hits). That's not imagination - that's measurable deviation from uniform distribution.

Those are local variations which completely average out over bigger samples.
Source : I ran statistics on more than 2^67 hashes for puzzles 67 and 68. They even out pretty well Smiley

In puzzles: φ might emerge from computational rounding, floating-point precision, or subtle interactions between the three crypto functions

None of those three things exist in the algorithms used.
You might want to fine tune your LLM, or start adding value and type your own messages.

Thoughts?

Bad news : you’re delusional.
Good news : you’ll make a lot of friends here.

@Bram24732 Fair enough! 😄
The mathematical question is: if φ governs Bitcoin markets and trading, why not puzzle distributions?
What would convince you that mathematical patterns might exist?

Trading markets are governed by human behaviour. I’m not surprised the golden ratio or similar constants happen there. On the other hand, the 3 cryptography objects we’re dealing with are designed specially to not have any bias. It hasn’t been proven they have a bias individually, let alone when combined.

Convincing me would require showing me a relevant statistical analysis which shows such bias. I even posted a .1BTC bounty for this on this thread.

Re: 71

Hello everyone,
I’m just an ordinary person who has poured every ounce of energy and savings into cracking Bitcoin Puzzle #71 for months.
This puzzle is unimaginably hard, with a private key range of 2^60 keys—far beyond anything I ever imagined.

I’ve scanned over 2^60 private keys, coming very close to the target address but still no success.
Every time I get close, it tears my heart apart, as my time, money, and energy drain away, and my life crumbles.

I have no money left, not even for basic living expenses, debts weigh on me like mountains, and I want to give up.
But a tiny flicker of hope inside me keeps me going.
I’m not chasing fortune; I’m just trying to survive, hoping for even the smallest help to breathe and keep fighting.

I sincerely ask you to help me. Even a tiny bit of BTC could give me the strength to live on.
I know it’s a lot to ask, but I’ve reached my breaking point.

This is my Bitcoin address:
bc1pe552kve5y4u4edvhq5egrw82e3zu9z8agtmywyysz9e2ajhtq5zsd5z0xu

Please help me. Give me a chance to survive.
Thank you, and may everyone who reads this be safe and well.

— A lonely, struggling, hopeful Puzzle #71 solo hunter

Did I just read “please fund my GPU rental for puzzle 71” ?

When making a bloomfilter for the x points of scalars 1...2**30 , what is the best hashing algorithm to use to get the lowest false positives candidates possible ?

Use x as an input.
This will give you the number of hash functions you need based on desired false positive rate.

I guess anyone who can't get past the definitions:

- "all hashes have the same equal chance of occurring"
- "independent events can't also be dependent events"
- concept of "order" or "history" doesn't exist on independent events

and prefers going to great lengths into the contrary direction (illogical theories) without doing any actual real research, really deserve the consequences of their ignorance, at this stage.

In other words, this thread's pure garbage anyway, so...

Well me getting 67 and 68 definitely weren’t independent events 😎

I get where you're coming from. It's definitely tough to get everyone on the same page, especially when each person has their own theory and approach.

But I'm not trying to enforce centralized control or reach some global agreement.

What I'm suggesting is more like an open infrastructure with a few basic principles. Not rules, just a framework. Some people have idle GPUs, others are strong coders, and some have solid heuristics. If we can bring those strengths together in a flexible system, everyone benefits.

Even if some prefer to work solo, that's completely fine. This doesn't interfere with that. It's simply an option for those who want to collaborate more efficiently.

If even a small group of three to five people are willing to try a structured approach, that's already enough to form a working foundation. From there, it can grow naturally if it proves useful.

yea i like the idea of "shared pool" like btcpuzzle.info(not really shared) but everyone got equivalent reward based on their work, what do yall think?

You mean like ttd71 pool ?

Maximum efficiency and faster puzzle solving.

Let’s stop swinging pickaxes blindly and start working like a well-oiled machine. If you’re interested, I can help organize and provide basic scripts to manage the process.

I don’t think you can reach any consensus on this topic. People are a little too sure about their idea of what’s real and what’s not.

I have four file around 50 Million value each file need to check every value off +-100K

That its puzzle will be solved

basically it's a waste of time, if you want to solve it just invest in a lot of gpu, there's no other way to solve it. Are you tired?

Why stupidy?
Rent

Where are the best options to rent gpu's in your opinion?

China. But it is best to travel to Beijing. And finish everything there on the spot. And bring a suitcase with money.  Wink

Which puzzle numbers have you solved? Did you work on them solo or in a pool? And how much time did you spend on all of them?

I suggest you read my post history it will be simpler.
I solved 67 and 68. I was managing operations but got funding from about 20 people. So it was essentially a centrally managed private pool.


Cool! Have you decided to stop here or are you ready to keep developing your strategic skills?

I stopped there. 71 is not worth it from a cost / risk / reward perspective

What computational power do you have at your disposal, and by how much would the range need to be reduced to make it profitable?

It’s variable since I rent the machines. But we peaked at tens of thousands of GPUs
71 is profitable at only a quater of the problem size.
