Bitcoin puzzle transaction ~32 BTC prize to who solves it

[nomachine]

A random number is a random number.

I can solve puzzle 40 in a reasonable amount of time using random numbers and a brute-force approach, whether I use Rust, C++, or any other programming language.

However, puzzle 68 is 268,435,456 times larger than puzzle 40 in terms of the range of numbers that must be generated.

Generating numbers in such a large range is not at all the same as generating numbers for puzzle 40. The computational complexity increases exponentially, making brute-force methods impractical for puzzle 68.

The other methods, such as the Kangaroo method, are very effective. However, if there is no public key, this approach becomes a dead end for ordinary computer users.

I have zero interest whether you read or understand my posts. Why are you replying to them, what good does it do to you, or anyone? You have ZERO merit after well a hundred posts, which indicates that if there was a downvote button, your merit would be a triple digit, but with a big minus in front of it. So what are you trying to do, nobody cares about your prefixes, methods, or anything. Well, maybe mcdouglas, but hopefully I already proved to him in a very empirical and practical way what his fallacy was, in trying to somehow acknowledge your ideas.

Also your last statement makes zero sense. You do realize that brute force / guessing means that after you scan 50% of some range you go above more chances of success than not, right? Actually, I don't need you to respond, so please don't bother.

False information is always false information.
You said they scan 57%.

Be careful too. Don't give people wrong directions or information. I said they scan 57% of what they consider PROBABILITY.

Again, by giving wrong information, you are ignoring PROBABILITY.
I have said many times before that it is possible to be between 6D-77.
I also said I am not interested in the rest.

I don't need support from anyone with a value or a button. Do you need it?

Stats say, on average, you will find the key at 50%. It may take you 1% one time, and 99% the next time. I have seen the last 2, 66 and 67, both solved around the average of 50%.

There are no probability or anything in cryptography only a wishful thinking..

If Puzzle 67 was solved , it was likely achieved using a combination of ASICs, optimized algorithms, and possibly distributed computing. They certainly don't have potatoes.

Can anyone share how to create the raw tx for MARA step by step and what code I need to create this tx?

[dastic]

Can anyone share how to create the raw tx for MARA step by step and what code I need to create this tx?

You can use even electrum, or ask chat gpt he will make you a script. Have you found the key ? Cause you asking like you have found it already.

puzzle 66 was found by a newbie and stolen by bots.
Now Mara has been discovered. But there are not many people who know how to use it. So helping people
If anyone knows how to use Mara. A detailed explanation would be helpful. Maybe someone lucky will find it, don't let the bots lose it.

Mara was already a well-known thing when puzzle 66 was stolen. You definitely need to use Mara. And it is confirmed that you can somewhat trust them. Using Mara is easy. You sing the transaction but DO NOT broadcast. Export it and copy it to Mara Slipstream. That's all. Solving the puzzle is the hard part.

1- First, you perform the transaction here. You take raw TX out.

2- Go to slipstream.mara.com and paste it, and follow what is given to you.

It's that simple.

Lets see how long its gonna take to solve 68

[hoanghuy2912]

To be able to use keyhunt's bsgs mode to scan and solve puzzle 135 as fast as possible, how many CPU threads and RAM are needed at the same time? How long does it take to scan the range 4000000000000000000000000000000000:4ffffffffffffffffffffffffffffffffffff?

What is your speed with Keyhunt BSGS? And what hardware do you use to run it?

[tmar777]

This puzzle is very strange. If it's for measuring the world's brute forcing capacity, 161-256 are just a waste (RIPEMD160 entropy is filled by 160, and by all of P2PKH Bitcoin). The puzzle creator could improve the puzzle's utility without bringing in any extra funds from outside - just spend 161-256 across to the unsolved portion 51-160, and roughly treble the puzzle's content density.

If on the other hand there's a pattern to find... well... that's awfully open-ended... can we have a hint or two?

I am the creator.

You are quite right, 161-256 are silly.  I honestly just did not think of this.  What is especially embarrassing, is this did not occur to me once, in two years.  By way of excuse, I was not really thinking much about the puzzle at all.

I will make up for two years of stupidity.  I will spend from 161-256 to the unsolved parts, as you suggest.  In addition, I intend to add further funds.  My aim is to boost the density by a factor of 10, from 0.001*length(key) to 0.01*length(key).  Probably in the next few weeks.  At any rate, when I next have an extended period of quiet and calm, to construct the new transaction carefully.

A few words about the puzzle.  There is no pattern.  It is just consecutive keys from a deterministic wallet (masked with leading 000...0001 to set difficulty).  It is simply a crude measuring instrument, of the cracking strength of the community.

Finally, I wish to express appreciation of the efforts of all developers of new cracking tools and technology.  The "large bitcoin collider" is especially innovative and interesting!

I've been analyzing the puzzle formation algorithm for two years. Just look at this information. After you figure this out, I'm ready for further dialogue.

It's part of the algorithm, there's another part, but what's the point of it all if the bots take the entire reward?

DM me, I may help further.

To be able to use keyhunt's bsgs mode to scan and solve puzzle 135 as fast as possible, how many CPU threads and RAM are needed at the same time? How long does it take to scan the range 4000000000000000000000000000000000:4ffffffffffffffffffffffffffffffffffff?

Puzzle 135 range size: 2¹³⁴

BSGS requirements:

1. Fast memory baby table: sqrt(N) items = 2⁶⁷ items
Item size: 256 bits in full; let's assume we only need the first 67 bits and ignore hash collision overhead

Total memory required: 2⁶⁷ * 67 bits = somewhere between 2⁷³ to 2⁷⁴ bits

The total amount of data stored on Earth in 2018 was 33 zettabytes. That is, 2⁷⁸ bits.

Estimates for 2025 are around 175 zettabytes. That s, all of the hard drives that exist on Earth have some total capacity of around 2⁸⁰ bits.

The amount of RAM is less than a fraction of all that (if you don't believe this, check any PC: what's the ratio between RAM and storage capacity?)

2. How many threads?

EC operations required at most: sqrt(N) for baby steps + sqrt(N) for giant steps = 2 * sqrt(N) steps

That is, 2⁶⁸ elliptic curve group operations.

A high-end CPU can do around 15 to 20 Mo/s per thread. However, we also need to check the table after every giant step. I will ignore this and assume it is a no-op (it's not).

Total threads needed to solve in one second: 2⁶⁸ / 20.000.000 = 14,757,395,258,968

In summary:

RAM: 1 to 2 zettabytes
CPU threads: 14.8 trillion (for 1 second of total work)

The numbers involved are so large and abnormal that half the people in this thread believe it’s a conspiracy whenever someone claims BTC from a puzzle. Some even think the creator is taking the prize for themselves

Thanks for the info. but according to the link you gave, won't the publickey be exposed when I sign raw tx in my electrum? in this way, aren't we actually broadcasting the transaction? Also, I didn't see such a step in the new version electrum. the question I asked may seem simple and funny to you, but I am trying to understand how people like me who don't know much can achieve this.
