Congratulations to the solver of puzzle 67, I saw that the solver uses MARA Slipstream. Is good to know that MARA works well for lower range puzzles  Smiley

same Y coordinate from two point, but still don't know how to calculate Lam 37718080363155996902926221483475020450927657555482586988616620542887997980018

I got lambda value searching... and found it in Hal Finney's post "Speeding up signature verification" ( https://bitcointalk.org/index.php?topic=3238.0 )

The lambda and beta values in that post are in hexadecimal.

lambda = 0x5363ad4cc05c30e0a5261c028812645a122e22ea20816678df02967c1b23bd72
beta = 0x7ae96a2b657c07106e64479eac3434e99cf0497512f58995c1396c28719501ee

Sure!  Cheesy
We know:
lambda * x = a [mod N]
x = a + 1 [mod N]

So:
lambda * (a + 1) = a [mod N]
lambda * a + lambda = a [mod N]
(lambda - 1) * a + lambda = 0 [mod N]
a = -lambda / (lambda - 1) [mod N]

Cool! now I can see it  Grin

Thanks a lot for the explanation  Wink

Hello there  Smiley

Congratulations to the winner  Wink

I think I'm lost with this red part of the explanation:

Another explanation:
It's a special point, if you apply endomorphism for it, you will get previous point (Point - G).
It's funny to have two points next to each other with same Y, isn't it?  Smiley
And since you know the distance between these two points, you can calculate the private key easily.
Congrats to the winner! Smiley



I'm trying to get the privkey with this information, but I think I'm missing something  Huh

Thanks for all the learning  Smiley

Greetings.

Guys i confused about this address :

https://www.blockchain.com/explorer/addresses/btc/34MSicAL7qVGkevFPLwyc9KohGzoUSnu3Q

here there are some outgoing transactions but
here say this address has not any public key

https://blockchain.info/q/pubkeyaddr/34MSicAL7qVGkevFPLwyc9KohGzoUSnu3Q


may someone explain this to me please?

Hello there.

The address 34MSicAL7qVGkevFPLwyc9KohGzoUSnu3Q is a 2-of-3 multisig address.

Its public keys are 036c75675da3fdc06a9e6940b4af97a856eb8801ed9b8c77941ac397f0abda5acc, 02502e76bc019532f74e0dad286477ccecacc1fc74695949ff368742fe9a5b4051 and 033960592197eeb6a199804eefc7e5db45c6570cea6e503d8616ccf939c691cd25

The redeem script is 5221036c75675da3fdc06a9e6940b4af97a856eb8801ed9b8c77941ac397f0abda5acc2102502e7 6bc019532f74e0dad286477ccecacc1fc74695949ff368742fe9a5b405121033960592197eeb6a1 99804eefc7e5db45c6570cea6e503d8616ccf939c691cd2553ae

What did you mean by this:
Quote
If you see mempool.space didn't see your mined TX before it was mined.

Never mind, I don't know what is happening with the mempool.space page because

My script works with that API (mempool.space), my script actually was trigger by your Transaction to start to work. (I checked it after post that message).

But if you see in the image that i post before:



The label was: "Not seen in Mempool"

But if you check that page right now  ( https://mempool.space/tx/bc16e7ce388d936c93583d17c5e691a2677ee9eabbc0ae6d03841fc5e0f1a386 )



Now the label change to: "Expected in Block"

So the page chage that label and i was confused by that.



Hey albert0bsd  Smiley

I just check the page right now and it still show me the message "Not seen in Mempool"

Well, I successfully beat any bots that were still in the game.

However, I will admit my first plan did not go as planned because I messed a few things up. But that's ok, I learned from it.

My successful withdrawal, was more of a hail mary versus my thought out, crafted, plan.

I am curious if any bots did get the signal and start working on finding the key and changing the transaction.

I will run another test from learning a few things, and after that test (not 66 bit), I hope to run another one here. Maybe even a lower bit one. We shall see.

Thanks for all of those who built bots and was in the game. I appreciate you.

Hello there  Smiley

That was a nice test. It confirmed fast and my bot was confused  Grin It took the pubkey of 1BoTWARSmLQSouDixHvKpLv6J5LgJYtrCy instead the right one.

Thanks for the opportunity  WanderingPhilospher  Smiley

64 was solved before the 10x so the values of the fork coins were not as tempting as they are now.


Then I just got the fork coins (only BCH, BSV, eCash, BTG, BCD and CDY)  Wink

Good to know that even after 12 minutes the fork coins were intact. So probably the situation is not that bad as we are anticipating


That day I got like US$165 between BCH, BSV, XEC (eCash) and BTG. It was cool to get that here in a latinamerican country  Grin

And, even today, fork coins weren't updated with 10x, so the prize is still the same for the fork coins (ie 0.66 BCH for puzzle #66 and so on)

During that time the puzzles had like 0.0064 bitcoin it and on top of that BTC was very low. Why would it create a world wide bot race and why would someone waste hundreds or thousands of dollars in fees to withdraw it?
It only became an issue once the creator increased the puzzle prize and since then, no lower end puzzle have been solved.

I suggest to take whatever time/scripts/motivation you have and try to solve puzzle #80 on wards instead where you will be guaranteed the prize.
Or, ask someone with knowledge about timings which is the lowest feasible puzzle to be solved that will leave enough time to withdraw without a bot snatchingup. I don't know this answer, could be even puzzle #70?  

If someone can answer that, that would be great.


Hello again   Cheesy

Puzzle #64 was solved on 09/09/2022. It's prize was 0.64 BTC and that day BTC price was US$21.268, so the prize in BTC was like US$13.611

Any puzzle below #80 or #90, I think, can be snatching up by a bot.

How was the Funds from Puzzle 64 transferred. There mist been a tug of war between the bots fighting each other during that time also. So how was it managed? Does someone know the story of that time. Same must have been for the Forks coin transfer of that puzzle as well. Another Tx another bot war ?

Hello there  Cheesy

I don't remember if there was a bot war for BTC, but I got the privkey like 12 minutes after the pubkey was exposed (but only with CPU, I don't have GPU  Grin )

Then I just got the fork coins (only BCH, BSV, eCash, BTG, BCD and CDY)  Wink
