The Kowala team will start working on BTC69 April 10th. Funding round 1 is ongoing, restricted to BTC67 and BTC68 participants. If there is room for extra capital (i.e the cap of 400k USD is not reached by April 10th) we will open funding to external parties.
Expected time to resolution : 2 to 4 months.
We are letting the world know so that people considering taking part in this brute force competition can decide to participate or not knowing all the facts. We estimate competition’s odds of success to be sub 1%.

Everyone has their own risk/reward ratio.
What matters is that people know all the facts.

Bad wording. If I understand correctly, it refers to the "others" (the external competitors) odds of success.

No one would be crazy to invest $ 400k with a risk of > 99% to lose the invested funds.

You forget what thread you're in. People twist things around 180, if you put a comma in a wrong place here.

But it might be understood literally as "the competition which was just mentioned odds of success".

Can I participate in solving puzzle 69 ?   I have a piece of paper, pencil, calculator and a pigeon to send the solutions to the cracking pool.

If not i will go into bitcoin solo mining ...

I think it's because you called the puzzle a "competition" and then right after referred to the "competition’s odds" and not, like, "our competitors' odds"...

So, yeah, slightly ambiguous use of the same word that could mean either the thing or the people participating in the thing:

competition - noun

2: a contest between rivals (a gymnastics competition)
also: one's competitors (faced tough competition)

I'm curious about a few things. Bram,

1- Why are you taking such a risk? (Wouldn't it be better to leave it at the top, since you have made a good name?

2- You did not ask anyone (other people) for any money or hardware for the 68th Wallet. Will those who want to invest now invest because you did not include them in the 67th or 68th Wallet? (For 1% chance.)

I read the article you announced a few times. I think the following result will happen. An average of 25% of old investors will not take this risk.
This shows that there is a deficiency of around 100 thousand dollars.

I think you have earned 100 thousand dollars. So would you risk it?
Or,
Would you like to collect this 100 thousand dollars after April 10?
But 75% of old participants will not come. (Because of the risk and because you did not include them in the 68th Wallet.)

In short, the summary of the event is as follows;

No matter how many GPU farms you have.
If Earnings > Capital,
You are gambling.
Your luck You can trust.

Bram, you made a good name for yourself. Now you're turning it into a bad name.
You'll lose people's trust and you'll become a laughing stock.

So many things are off in this message I won’t take the time to respond I’m sorry.

Where can you rent for that price? Could you tell me?

Full Setup Summary:
GPUs: 350

Speed per GPU: 8 GKey/s
→ Total speed for 350 GPUs: 2.8 TKey/s (2.8 trillion keys per second)

Range: 295,147,905,179,352,825,856 (total number of keys to be processed)

GPU cost: $0.18 per GPU per hour  https://salad.com/pricing

Reward: 6.9 BTC, which is approximately $483,000

Key Calculations:
Time to complete:
 ≈122.2 days

Cost Calculation:
Hourly cost for 350 GPUs:
=184,766 USD

Net Profit Calculation (assuming 6.9 BTC ≈ $483,000):
Net Profit:
483,000−184,766=298,234 USD

Summary of Results (350 GPUs):
Time to Complete   Cost (USD)   Net Profit (USD)
~122.2 days   ~$184,766   ~$298,234


seems its last puzzle to solve, no safety margin needeed.
pure profit fo RC

There is no such thing as investing in hundreds of gpu, don't listen to the fabricate

[Bram24732]

I apologize in advance, I don’t want to offend anyone.
I just want to make one thing clear: it doesn’t matter whether someone has over 2,000 GPUs or just one old GT card — the chances are almost the same for everyone. The only difference is that the one with more computing power pays more — they take on more risk, and yes, they have a slightly higher chance. But for the rest, there’s practically no risk at all.

The whole idea behind this "game" was to show just how "perfectly" the network functions. And if someone finds a vulnerability, the goal is to fix it as fast as possible for the sake of security. So, in a way, we’re bug hunters — and I’m genuinely impressed by RC. He went much further to tackle more complex ranges.

Everyone has their own approach to searching for private keys in this game. I, for example, don’t use a GPU. I based my work on keyhunt with heavy modifications, and now I’ve reached 400 Pkeys/s on an old CPU, even though initially I couldn’t get above 60 Pkeys/s.

P.S. Please don’t ask for the code just yet — I’m still working on improvements, and once it’s ready, I’ll share it with you.
P.S.2. RC, your SOTA method is very impressive and flashy, but not very efficient (sorry). It’s a good method though, and I did start using it myself — until I found a new solution.
P.S.3. Bram, there’s so much buzz around you, but I still have some doubts.

Doubts about what ?

[crytoestudo]

wow you're going to share the code. i don't even know what to say. i also only have cpu.

I have doubts about the computational power — with that many GPUs, you could’ve soloed 69 and come out ahead. Maybe I’m wrong (though it’s unlikely), simply because I don’t know your actual speed. But in reality, the ranges can be narrowed from the very beginning (and if you’re a cryptographer, you should have noticed something).

Rumor has it, if you flash a custom firmware to a doorbell, it can do 7 exa keys/s.

I think most people are unaware that skipping 7 exakeys/s, or even many many multiples of that, in a space of exponential size equals jack shit.

Let me guess: you think BSGS is even remotely feasible for anything above 80 or so bits, right?

There's nothing (and there can be nothing) faster when it comes to real keys/s then purely adding some public keys together without any side-step requirements (such, as, uh-oh, making some table lookups at every freaking step). Guess what's the name of that algorithm?

Just stop while you are behind lol. You have no idea what is going on, the entire process.

I would take a flashy, non-efficient, Kangaroo program like RC's over a BSGS getting 400 Pkeys/s on a CPU, any day of the week and 3 times on Friday. Do you understand the difference in the two programs?!

But hey, we are all looking forward to you solving 135 and 140 with your heavily optimized BSGS, that isn't public. Hmmmmm, which is weird because I am sure RC and Bram have optimized codes that they have not made public either...but you question them lol.

[crytoestudo]

I understood that it is not now. And I wish you have wisdom and intelligence to achieve your goals. Let's ask our friend Bram24732 to support your cause lol He is too much of a beast. I had the pleasure of talking to him (Bram24732) he is very polite.

wow you're going to share the code. i don't even know what to say. i also only have cpu.

Sorry, but not right now — if I had a couple thousand in support, I’d be able to speed up work on the project.
