Bitcoin Forum

Not too long ago Bitcoin wasn't worth much (USD wise) but as an early adopter I was there! Mining them on my desktop computer on a daily basis. At a later point in time I even bought more, a lot more. This was my best investment ever!


My Bitcoins quickly became a treasure chest and while I don't want to provide numbers I can tell you that Bitcoin changed my life for good.
On top of that, bitcoin airdrops were created. I thought it would be nice to give those away to someone else in the universe, as I don't need them.
Just for fun. ( In the end I got them for free too ).


Thinking about ideas on how to do this I finally created a bitcoin challenge where BTC is to be found, hidden in a digital picture.
I have to admit it wasn't as easy as I projected and I had to exchange all airdrops for BTC.
While this wasn't a easy process for all of them, creating the picture was the most difficult since I'm not a artist myself.


Today, finally, I can announce the 310 BTC Bitcoin Challenge.

Yes, that's correct, there's 310 BTC hidden in the picture.



Head over to https://bitcoinchallenge.codes/ (https://bitcoinchallenge.codes/) for more details.



Good luck!

Pip

I'm not sure I posted this in the correct category.
If not, please move it the correct location.

Seriously, what is the point of this? I suppose you don't intend to give any hints.  :)

Interesting challenge  ;D

I did not succeed in verifying your signature, probably because your address starts with 3.
Is that a multisig or a  P2SH-segwit address?

If I see no progress I will release a hint or clue but not at the moment.

You can verify the signature in a wallet like, for example, Electrum.

mate but are we looking for a long private key? or a mnemonic phrase with several words? :'(

Yeah, at least tell us WHAT to look for?

How can we contact you to verify if the code is correct?

Friend
knows that you do not get to see the differences between "0" and "O"
Do you have any way to differentiate "O" from "0"?


thank you very much, very entertaining the game

Looks you lost the the private key for that wallet and looking for someone to crack that private key code for you or you looking for methods to  to crack private key code for bitcoin wallets.

Interesting, i will give it a go

Electrum does verify the message. Still I am very skeptical.. seems like an insane amount for a puzzle lol.

By looking at associated addresses, this could be:

0.31 - 3NPZiNWiD7cCfXZa1D8tnEZBPgQ884cVw7
0.2 - 1G7qsUy5x9bUd1pRfhVZ7cuB5cMUP4hsfR
0.1 - 1446C8HqMtvWtEgu1JnjwLcPESSruhzkmV

310 BTC is very large amount of money...

Interesting challenge. I found some clues already incl a link to register. No private key though.
What do you mean by "... the data you got so far"? I am not sure what should be included in this SHA256 hash.
Edit: "the data" could mean everything incl. your postings, the website and so on. If we are only talking about the image it could be everything incl. metadata, size, visible and hidden numbers, fields, pixels etc. in endless possibilities of combinations of these all. Makes no sense this way.

I hope the winner buy THX tokens from me if he get the prize. ;D
That was kidding but really hope the winner donate some btc to a charity because little of this amount can help many people.

Yeah, this make no sense, if we don't know even what kind of access we're looking for, a long PK or just a mnemonic, also this person gotta try to prove that the prize is legit in a different way, otherwise i don't think the people take this serious because is a considerable amount of money.

Satoshi is it you?

Can you prove the money is there.. 310 is huge :)

Probably more like stenography instead.

There is a step by step video tutorial on how to reveal THE HIDDEN LAYER in the puzzle. It is real.

Sorry,edited.

Still too complicated for me, have you made any progress at all?

this looks very bad for us the unintelligent

a friend told me how the .1 BTC was accessed and I know of 3 encrypted files (pure salted string, pkzip with salted string inside and the rar with password protection) hidden in the image, the qr, and the special image inside with additional chars (this was rather clever, i have to admit). now everything is password protected and i'm stuck

Did you plan this puzzle to be solved sooner rather than later? Do you hope for weeks, months or years?

This is my first experiment and I did not design this thing with a particular time frame in mind.
It could be solved in a matter of days, it might take months. I don't know.

Is your friend "Lustre"?, the guy who found the 0.1?.

A friend got it from someone on social media.
I don't know who told who specifically

Another account farmer

I am missing something. Are we supposed to find the private key to the address?

Obviously. You can't spend BTC without the private key.

we decoded one of the encrypted files.
it reads "Well done! Now find something interesting here:"
followed by a bunch of seemingly random numbers.

how many steps are there?
can you give us numbers?

oh and I can no longer access your site after scanning things.
can you unblock?

Maybe the seemingly random numbers are the privkey ;)

If you want to solve a $2 million dollar problem, be a $3 million dollar man. If you are not a $3 million dollar man, think like one!  

I believe I am going to employ 15 persons on $2k/month for just one month (it's not a big amount so those smart people should take this risk with me). If we find it, we share the prize. If we don't find it, we enjoy the experience we had together and me losing some cash. I think you must be crazy to believe you can do it alone.
This guy is for sure a genius who can solve world's problems with his knowledge and skills. I would have loved receiving more information because it was unclear whether we were looking for the mnemonic, private key or anything else.

Regarding the challenge, the guy is too smart to allow you getting 310.00 BTC without getting first 0.1 -> 0.2 -> 0.31 BTC
He is smart, he probably has an entrepreneurial mind. Would people still try to get the 0.2 and 0.31 BTC if the 310 BTC would be already rewarded? Probably not.

And you could not give the solution to the private key of the 0.1 BTC wallet, I mean, it's already solved, right?

Shouldn't this be in Games and rounds (https://bitcointalk.org/index.php?board=71.0)?

Are you by any chance the Pineapple Fund owner?

How about this little theory:

A hacker has commited a grand bitcoin theft a while ago and is now trying to clear the trails to these Bitcoins through a puzzle. The one who will win the grand prize is the hacker himself, who can now hide behind the claim he has won the Bitcoins with his sheer knowledge.

Edit: Maybe the victims can ask for a subpoena to check a certain Binance account? Maybe there is another account at Polo, that might be interesting for LE.

A few addons to my theory:
(OP's wallet from 04-04-2018 until now)
https://www.blockchain.com/btc/address/3KCEGC4GaATQCnzogrpSDRJLKAjWvgudmW (OP's wallet from 04-04-2018 until now)
https://www.blockchain.com/btc/address/13hLyfRHg7p9Zw7WHToRT67JR1HR92Mvxw (OP's wallet until 04-04-2018)

https://pics.ballmemes.com/0000h-shit-you-done-fucked-up-now-30414468.png

Maybe the 0.1 wallet is part of something bigger. Maybe it's not.
Either way, if I were to publish the steps, I would be unintentionally giving that away and it is too early for hints already.

I won't even try to solve this as I'm an idiot (I could have enough money from crypto for few years but I sold instead hodling etc.) but I found this very interesting:
Wow man, these had to be hell of airdrops  :o
Best regards to my family, everyone involved and all good people
^^^ in case this topic is in TV  :D


Wow

Are you kidding me?

What a great post! You deserve more than anyone to solve this puzzle and I really hope if someone does you get tipped.

Thank you so much even just for the time and effort you put into it.

give me your contact info and we can get started

Hi

I tried to pm you about some info I have decoded. But I got the following error:

User 'anbei22' has not chosen to allow messages from newbies. You should post in their relevant thread to remind them to enable this setting.

I don't know if I'm on a track or not at all and I'm doing this as I can, but on the forums dealing with this puzzle I found nothing like this.

- On photoshop, since the original image by making a threshold in value 1 and de-zooming of the image I get this image that I call "A" with regular points
https://imgur.com/uJe9tET

- In the same way with a threshold at 255 I get "B" which reveals dots and the outline of the QR code at 0.1BTC
https://imgur.com/8P6hOTu

- By adding A + B + The original image I notice that the points appear in some cells of the image as well as on some of the curves of beziers. Moreover the points of A appear on black background and that of B on white cells -----> it is possible that I didn't reveal all the points which should appear on black or white background.
https://imgur.com/ntHB83M

- Always starting from the original image, doing Image / Settings / Equalize then a threshold to 255 and finally Zoom Out I isolate some points that appeared on B. I thus call this image "C"
https://imgur.com/p5CRL5G

- By making A + B - C and by putting colors in them, we can distinguish some kinds of regular grids intertwined
A in red
B in Blue that seems to have other grids to isolate
C in green
https://imgur.com/D627qSc

This last result makes me think of this puzzle in the same genre:
https://steemit.com/bitcoin/@mmorsl/solution-of-the-bitcoin-crypto-puzzle-level-4-by-zden

I suppose that if we connect these points and grids with the Béziers curves we must obtain something. I don't know if it has something to do with the 0.2BTC wallet just discovered. For now I'm blocking
If it helps someone, don't forget me if you find something ;)

I'll just leave this here

https://i.imgur.com/th0pqhg.jpg

The use of the word bigger in this sentence gives away that the answer it's in the first option. Enthusiasm about the question and people's interest  makes people use words like "bigger" or other adjectives that tend to stay where the truth is in the sentence.

i will tend to believe that the 0.1 wallet answer has to do with the 0.2, 0.31 and 310 BTC wallet.

That means most probably the other 2 wallets 0.2 and 0.31 are also part of the the big answer.

Very curious about the final answer and about the difficulty of the last one... is there an end date? like one year or something?

I found it on the first assignment. But it is already empty.
https://www.blockchain.com/en/btc/address/1DeVCjUDvykHmf3TPn5JoBoikabXn3e7CN

Hint: https://imgur.com/a/OVcLilX

I think there is no end date.
But unless OP decides to pull out (as it has happened before - I saw such cases on reddit) I think it'll be solved pretty quickly, as you can see there are at least several groups of people trying to decode it and probably many other such groups are hidden, there is a lot of money to be won so expect fierce competition.

when i readed all the post and replays of members, now i understind i am sure that i will never get the 310 BTC    :-[

Don't fall for the lies of "crypto_jedi_ninja". If it's a joke, it's not funny.
Not only isn't funny, it's misleading!

 I have a better idea.  Send me 9 and keep the 1 for yourself.

It works out the same and nobody has to pay an escrow service.

The crackhead down the street got hold of a laptop.

Hmmm, It seems this is not a "NEW" Puzzle...

Here is something I found from JAN 2018 about this same Address with the 310 BTC.

Very interesting activity, I am ready to accept this challenge, I think this will become a topic that I will pay attention to every day, because I encountered this kind of challenge for the first time!

Get up to speed on the 310 Bitcoin Challenge

While completely fascinated with this, it’s distracting me from important real life priorities.  I’m more or less obsessed with this puzzle.  After examining many elements of it, I have to come to terms with the fact that I don’t have the educational background or experience to solve this.  By the time I cracked it, it would have been done already.  

I can only follow the bread crumbs of other much smarter ladies and gents than myself.  Frankly, I must say I find it frustrating that Pip has created this to only be solved by those with a knowledge of computer science math, cryptographic curves, languages, the inner bones of the back end of BTC wallets, image/message encryption and other complex fields of study.  It puts the majority of people at a great disadvantage.  

The people who are knowledgeable in these things are the types of people who more than likely already have plenty of Bitcoin – likeminded to the creator.  It seems to me that much of the ethos behind Bitcoin is distribution of a network and massive wealth transfer.  Why not make these puzzles to have a chance of falling into the hands of every day people and broaden the scope of that network?  Why not use this opportunity to further encourage adoption, rather than further scare people away?  The  BTC are just being moved around the same circles this way.

Well, it is what it is, and no amount of guilt tripping anyone is going to change anything, but I think it’s a valid question to consider.  No one has to make these puzzles at all and they are free to construct them however they like.  All I can do is what I can do.  So I’ve systematically assembled bread crumbs.  Will they lead us to a solitary place in the woods for the final answer?

Here is a collection someone is assembling of what’s been determined thus far:

Being as the first line of the grid was all converted to 310, indicating the solver was heading in the right direction, someone else appears to be making further progress using the grid.

An interesting discussion on Discord:

pastet89
To be fair I am even not sure if the first line is garbage at all. Think about this: how about if there is a second shift key and when we put it on the same grid the other way around happens: the two middles lines are 310s and we get words seeds from the other lines? And that might be the seed for the 310 BTC. There is something symbolic in that 310. 310 challenge, 310 written on the corner and the hidden code was on line 310. I think that this or the red salted string contains the key to the wallet with 310 BTC. But they might contain the same info but need multiple keys to give multiple results.

Noah
I also think we will need multiple keys /longer bip39 string for the 310 BTC wallet.
Maybe that’s how he ensures linearity, every wallet is a bip39 string with the next 12 words added.
That’s also why he used the same line to generate the 310310310 line to indicate you need to concatenate the two results for the next one.

UPDATE:

Solution to the 2nd wallet has been made public and is in the "Ramp Up" document above.


What do we know for certain?

•   The first wallet has found
•   The 2nd wallet was found but no one knows who did it yet, not even Pip
•   It’s futile to try to brute force the hash or access to the backend of the site – it’s been secured
•   The solver of the 2nd wallet address has not contacted Pip and hasn’t been public with his knowledge.
•   You don’t have to be registered to solve the puzzle, as the first winner was not.  But both winners seem to be now as the site said 2 have been registered.
•   There are 2, or more, binary strings.  Only one has been solved.
•   Before the challenge went public, Pip sent 310 BTC to the 0.31 wallet in batches of 10BTC, emptied it, then sent the 0.31 BTC.
•   The 22 Characters in hand written in plain site (in no particular order): L503K7DF64C120E8A9D9F4

What do we know (or think we know) about Pip?:

•   He mined BTC early on as an early adopter
•   He bought a large number of BTC fairly early on
•   He received airdrops which he went through the trouble of converting to Bitcoin
•   He has lots of Bitcoin
•   He doesn’t want to share his identity – I don’t blame him
•   Most, or a considerable percentage, of what he is giving away was received in airdrops
•   He seems friendly.  Other than the facts that he is willing to give hints if/when needed he sometimes responds to people and dropping subtle tips, he using phrases like, “have fun...”, “Good luck!”, “Don't be sad”, “please accept my apologies” (when he doesn’t owe anyone anything), and “...my friend”.  “If you find the code, please get in touch with me. I would love to hear details about your approach!”
•   His choice of words, grammar structure, and “tone” sounds American to me
•   He is not artistic, saying,  “creating the picture was the most difficult since I'm not an artist myself.”  This makes me think the filters on the image are just that, photoshop filters, and mean nothing more.  Unless perhaps, he had help putting this all together.  But, the fact he says it was difficult sounds like he did it himself, because getting help would have made it easy for him.
•   He doesn’t want to give to charity for his own reasons and doesn’t want to discuss it.  (Which is fine – he owes none of us anything)

Quotes from Pip:

•   “Hints will come if I don't see progress.”
•   “Don't expect to find it in just a few hours or days but if you do, you're very good!”
•   “This is my first experiment and I did not design this thing with a particular time frame in mind.  It could be solved in a matter of days; it might take months. I don't know.”
•   “Over 10 people asked the same question: can I solve the riddle by printing it out on paper and looking for clues while on the bus.  Let this be my first hint: Partly.”
•   “Good morning all.
First of all I want to apologize for not answering all emails.
You guys were asking me about financial advice, money for startups or family, a head start by providing a good tip, or other strange questions. I could not even understand all of them. I can not help everyone, please accept my apologies! Someone was very very angry at me and blamed me for a lot of bad things that happened in the world. Sorry man, I can't save the world! :(
I can not answer all those emails personally, I'm sorry. I will try to answer those that deserve a reply as soon as possible.

Important updates:
- Last night the first successful registration happened. Many of you know what I'm talking about. If not: keep going!
- About 4.5 hours later the second wallet (0.2 BTC) was discovered. The funds moved to
bc1q75ezmkfj5am2tqvr3vl8h90ldtvn7ha6sx0t4n
I don't know who solved it, yet, but I will certainly reach out to the first (and only, for now) registered email address.

•   From https://bitcoinchallenge.codes/register-310/ :
“While it is possible to solve the riddle without registering, at this point I would love to hear from you! Why? I would love to know who wins this challenge.”
“Tell me.  What is the SHA256 hash of the data you got so far? (SHA256 of all data on a single line.)
“Note: The form expects a sha256 hash in hex format and it is not case sensitive.”

•   “People are posting hashes to the "hidden" page url.  Let me tell you one thing: Don't bother posting there if you don't know how to access the 0.1 BTC. (You won't be able to provide the correct hash yet)… The form does not expect the hash of a private key. That I can tell you right now.
   It already received over 20K hashes so far, from all over the world. It's just pointless    trying to find a valid hash for it if you don't know how to access the 0.1 BTC. You can    consider this as a small tip (and save yourself some valuable time).”
•   “Maybe the 0.1 wallet is part of something bigger. Maybe it's not.”
•    “This one I can tell you: there is no O (ooh) but only a 0 (zero) if there's something that looks like an O or 0.” (When someone asked about the Os on the image)
•   “I downloaded the website template from a free template site.”  (When someone noticed the sites identical theme to another)
•   “At first I just loved the idea and I played along. Later I started to actually believe it would become accepted one day.” (When asked how he got into Bitcoin)
•   “If you were scanning or trying to hack the site you might have been blocked. If not, please be patient. The site is under heavy load.”

How can we categorize the different parts which need solving?

PHOTO MANIPULATION
•   Uncovering the QR code and binary strings attached - The LSBs
•   The original image itself and the filters applied
•   Examining pixels, layers, color levels
•   Other
COMPUTER LANGUAGE CONVERSION
•   The hex grid on the bottom – denoted by the #16
•   Salted String, etc
•   Cryptographic curves  
•   Bezier curves?
PLAIN SIGHT
•   Bitcoin logo, grid, and computer generated curves
•   The hand written characters on the image.
•   The original image itself
•   Mnemonic seed phrase?
STEGANOGRAPHY
•   Voronoi Diagrams?
•   Software encryption?
EXTERNAL SOLUTIONS/CLUES
•   Things to be found outside the image that clues in the image might lead us on a trail to
•   Morse?
OTHER?

Possible clues/approaches.  What might we ask? (Each trail may lead us to a red herring, but it may be a good idea to use the process of elimination and explore every possibility.  I imagine some people will have been inches away from finding something before they turned to another direction):

•   Pip calls himself Pip.  What is this in reference to?  (Pip can mean different things)
•   He chose to launch this on Oct 2 – does it have any relevance other than for being used as a shift function to solve the 1st wallet.
•   Do the filters applied to the photo (B&W, stained glass, graphic pencil, texture) matter?  Or are they just filters applied to an image?
•   Does the image choice of a forest mean anything?
•   Are the curves Bezier curves?
•   Is it a Voronoi diagram?
•   Is it a mosaic puzzle?
•   What does Pip mean by, “the data you got so far.”  Is solving each piece progressive, dependent on 1 or all of the former solutions?
•   Does morse code have anything to do with anything here?
•   Is there a clue in these words themselves from the seed phrase of the first wallet?  Notice: lyrics, rhythm, music, and fury, horror, mansion – may not be random.
•   When he says it can be partly solved printed out and riding a bus, could this be the final step, as in you have to travel somewhere to claim it?
•   Is there a file hidden in the image using encryption software?  People have scanned the file and said no – but are they right?
•   The 0.2 wallet seed phrase is the 0.1 phrase + goldfinch hex to pib39.  So, possibly the 0.31 phrase is 0.1 + 0.2 + X.

If I was helpful to whoever can solve this a tip of 1 or 2 BTC (or 10 – lol) would be immensely appreciated and go to a good cause!

Pip – you can’t save the world, but you can certainly make some meaningful differences in your sphere of influence.  Not saying give everything away.  Multiply it and use your resources prudently for good.  How about crypto education of the masses yet to adopt?  It seems you are passionate about the subject.  I have a project I’d love some help with. ;)

ops i am too late. first wallet empty  :'(

Wow!  Some people have no sense of humor.

Seems insane to make such a large challenge when you plan on doing others.

I'd like to see the OP move the funds before i even bothered to start something like this.

...and it's over!

  I think everyone who post in this thread deserve small reward. If the winner see this he should tip everybody 3.1 btc , so if he read this let him decide.

Congrats to winner.
Hope he/she donate some of this prize to charities and helps people with that.

I found half part key only look to paper but not spedy. I check next puzzle.  ;D

Why does everyone want others to donate to charity? In charity, it is full of vultures that fill their pockets and do not help their patients. In addition, these charities are used to launder money.


an advice, NEVER DONATE TO CHARITY

Those wicked people make money with the disease of the people


If you really want to help someone, do not give him the fish, teach him to fish his own fish

So who won? I kinda doubt anyone who won such a large amount of coins would stay silent..... What..No bragging? What about the other winners? Smells fishy.

I will continue to solve this puzzle, can't sleep last two nights for that!!!

I didn't mean donate to charity exactly, I mean donate some of the prize to people who may need money and donating to charities is one of the ways.
Simply I could put a btc address and ask from winner to donate but this amount of money can help many people so I just suggest, the winner can donate some of that to charities and obviously, I mean legit and Honest charities, I don't think all charities act like thieves, I'm sure there is honest and legit charities that help people.
If you insist all charities are thieves, you can read my comment in this way:

Congrats to winner.
Hope he/she donate some of this prize to people who may need in money. Donate to legit charities is one of the ways.

Congrats to the winner 👍
I couldn't take part because of my health issues even posting on this forum from chromebook is an issue for me, let alone using desktop pc and hacking  :-\
But maybe I'll find some drug to kill the pain and other problems and will be able to take part in next Pip's challenges  8) [honestly don't think so  :'(]  


Not everyone is using throwaway accounts, in many countries you may get killed for having such amount of money, maybe he's thinking what to do with it.


Well, it's crypto wild west, trust no one  :P

That was fast. I guess it wasn't necessary to find all 3 smaller prizes first to get the 310 BTC; the 0.31 BTC puzzle remains unsolved.

Looks like it wasn't or maybe only part of the solution for the smaller puzzles was required to claim main prize, so the winner left it to focus on it and right now after getting big reward he's no longer interested in "mere" 0.31.
I just don't get two things.
Why the first 3 rewards are so miniscule in comparison to the grand prize? Something like 0.1, 2, 31, ~270 would be better, wouldn't it?
And what's the meaning of 310? There must be some meaning of it.

That was so fast. and also i was late. i solve the first wallet too late . so now when the second quizz to prepare well.

Wish I could of solved the puzzle in time but I wasn't able to.  Congrats to the winner, I hope you enjoy your bitcoins.  Wish I won because right now I'm homeless :(

don't feel sad!! well if not the puzzle what else do you do ? where are you located ?

never always cast yourself out!! lots of trying time people around the world always go through

the puzzle more will come!!

guys how would i try pputting in the private key i went on blockchain > import > but it says its not sepndable how do i test the private key

This was a super cool challenge. I've tried  to showcase how to solve and find the 0.1 and 0.2 BTC Wallet information. I hope this helps some people learn how to approach these kinds of puzzles!
https://www.youtube.com/watch?v=Vbzwkl4MlLs

I see that people are enthusiastic about donating. I can suggest that in the future you leave a btc address for donations from people. Then when it's full enough, put together another puzzle to solve. So it helps keep the community entertained by solving puzzles, so I see this keeps everyone at ease. Thank you very much

@ solver let us know the solution! whats need to be done after registering on website? I guess further tinkering with the hash that had to be put into it?

Just quoting myself. Well played, OP.

Congrats to the winner!!!
Can someone give me Pip's email?

Congrats to the winner!!!
Can the winner share the decryption process? thanks

Congratulations to the winner :)

Let us know the solution.

I think I had solved 60-70% of the puzzle.


Coral, Item, Half, Road, Cry, Gun, Dumb - I guess these were the 7 words of the BIP39 Mnemonic

Loop, man, foil, baby, bag, zero - of these 5 words could be the remaining



I hope the pip or the winner makes the final solution public (if not the method used).

Awaiting the next puzzle:)

Congrats to the puzzler if this is real, though i find it pretty strange to have these small wallets solved, then the 0.31 skipped for the direct route to the 310 wallet, and shouldn't it be 310.61btc?

I am impressed!
bitcoin-challenge keep rolling!

The winner (or team winner) is really smart! I'm happy for that and I hope he/she use the money to make good actions (not give).
I`m waiting the next puzzle!

What's the mail of Pip?

pip@mailinator.com

Not totally over yet, the site says > 0.31 BTC (unsolved)
But I guess the price is not that tempting as the 310 BTC...

BTW sent a request to the mods to be moved in games and rounds section because in Off-topic things get lost in the spam but..
https://i.imgur.com/2hlZwGG.png

if you look at adress its getting split in 25 btc seperates wallets. hmmmmmm ??? ???

If your theory is right, making the 0.31 part unsolvable would be a nice touch  :D

I found an interesting link to other bitcoin puzzles there must be too many bitcoin millionaires out there looking to just make some fun entertaining tasks for people...

https://www.reddit.com/r/bitcoinpuzzles/ (https://www.reddit.com/r/bitcoinpuzzles/)

I hope the winner makes a video on the solution. Would be glad to learn :)

I guess for privacy and tax reasons.. we might never really hear of the winner....!

Happy for the winner.

Ok, so you still think it was just money laundering?


I think that someone who was able to solve the puzzle know how to hide his identity  ;)
Oh man, any idea how many more words you needed?
Congrats on being so close  :)


Maybe a team solved the puzzle and they're splitting the reward.
Or the winner doesn't fell secure storing whole amount in one wallet.


Yeah, for sure, people will donate tens of bitcoins for puzzles, OK  :P

Why does it matter to you, what a random internet user thinks? Would you try to convince me of your opinion, if I say yes?

I'm pretty sure there is some story behind this particular wallet with 310 BTC. You don't just give away your money. Do you know a lot of people who give away money to strangers? I don't. Thinking of reasons why someone could do it:

1. He can't use it himself due to some legal issues (has access to internet but no access to banking, for example). I don't believe in this story that he "is at the point where he does not care about larger amounts of money anymore". It's not how it works. Whenever you have more money, you start making more plans to spend it, and you don't consider that lot "a lot" anymore, thus you always want more. Everyone who went, say, from broke to middle class can prove it.
2. He is terminally ill or crippled and does not care.
3. He is doing it to prove someone some point (e.g. I'll burn my money in a fireplace, but I won't pay for your new car)
4. Maybe he's trying to prove the point that money, in fact, ruins your life instead of changing it for the better? What is this reference to charity? Most millionaires actually DO charity. Bill Gates, Mark Zuckerberg, just to name the few. Are they idiots? I think not. )
5. The funds are somehow locked in this wallet and he does not know the solution in full himself
6. He is actually not allowed to touch the funds (as per suggestion in one of previous posts), so he needs someone else to move them
7. The 310 problem has no solution (and it's not even included in the picture), he just took it himself. Now that the 310 BTC is claimed, why is Mr. Pip not disclosing the solution to the 310 BTC wallet? Maybe because it does not exist?
8. Maybe this picture is only a key to a much larger amount of BTC, so he needs help solving the first picture, and he'll try to solve the 2nd picture himself. ))

Would it not make sense to create, say, 10 wallets 31 BTC worth each? To give someone an extra opportunity? Why is it 0.1, 0.2, 0.3 and 310?

I don't think this could be actually called a "challenge". RSA large number factoring was a real challenge. It provided an incentive to create new algorithms, hardware devices, it attracted people to the problem. But what's the practical use of this "challenge"? Other than guessing someone else's weird riddles? I personally find it humiliating and condescending. I am not a hell of a programmer, but I can easily create a twisted "challenge" most people won't be able to solve, yet with an existing solution. With the amount of computer science knowledge needed to solve this, I'd personally better work on my own miner to live off devfee. At least, I'd be doing something useful.

p.s. I agree with one of the previous posters that this person is probably American. The niceness is probably due to the fact he's not a young person, I think he's in his 60s.

I made it a bit bigger :)

Can you remove the Bitcoin address from your quote? I've reported his begging for deletion, so please remove it too.

The fact that there still is no solution even from op, is a red flag for me. Probably just some millionaire trying to launder his coin.

There are roughly ten red flags regarding this challenge. By now I would be very surprised if this wasn't a hoax.

SCAM !!!!

hhahaa

I am more interested in knowing the conclusion of the 310 to learn.

By now it's very likely, that either no solution exists or that the solution requires absurd leaps of logic, so that noone will find it.

Hello ...


Yep .... but .... it's been found ....  ::)

I look at the BTC address and there was no balance to it already 310 BTC were sent. I guess someone got it the first.  Can they show us here how they found it?

310 BTC is huge. You're one of those rich guys if you have that about of BTC these days. I can't imagine someone is giving that much. But yes must be richer than anyone else.

Update from Pip
- Oct 14 2018: The website was getting more visitors on a daily basis. Exponentially. The server even had troubles serving all of them. Until the 310 BTC wallet got cracked. Now my daily visitors chart is very very bearish. I mean, very very very bearish. Down over 90%! If I were to chart the amount of emails on a daily basis it will most certainly look very similar. It feels like there is no interest anymore. I'm puzzled the 0.31 BTC wallet is still unsolved and the remaining coins in the 310 BTC wallet are not even moved days later.....

- Oct 14 2018: In the next weeks I will have someone build a new website and I will start one or a couple smaller challenges ( 0.X BTC ). Those I need to set a baseline in order to try and make sure the next challenge will last a little longer while not making it impossible to solved these tihngs within a reasonable time frame. Keep an eye on the website!

That's what this forum is all about.

Maybe it's time for a little hint?...

I am still trying to solve 0,31 and also 310 for interest. Hope not going crazy soon.

Is solution for 310 posted somewhere?
I'm curious, but not curious enough to search for it  ;D

I doubt it ever existed. You don't give your money away for nothing, it just doesn't happen.

Finding the techniques in this photo is very difficult. If you can find it, you have to sort it out again. This needs support from AI to accomplish these operations.

OK. Then let's start. I 'still' think, this is some kind of a money laundering scheme. The guy(s) who got the 310BTC can easily say 'I won it' when beeing asked by his gov where the money came from. Maybe lottery/puzzle winnings are free of tax in the country of OP, while trading winnings are taxable for example. Or maybe OP has scammed/stolen money, which has to be turned into legal money.

This is way more possible, than 'a rich guy who wants to give 2 Mio $ to a guy who is at least as smart as himself'

The 1000 BTC GIVEAWAY! From your friend rekcahxfb (https://bitcointalk.org/index.php?topic=1574127.0) (ignore the red trust, that's from after the account got hacked) raised similar questions. He also dropped some money on a few users and signed a message to prove ownership of funds.

I don't know how relative this still is but i made two step by step guides for 0.1 and 0.2 BTC puzzles from 310 BTC challenge so that anyone can follow and try things out from the puzzle:

0.1 BTC puzzle (https://onlinebitmania.blogspot.com/2018/10/solution-to-01-btc-puzzle-of-310-btc.html)

0.2 BTC puzzle (https://onlinebitmania.blogspot.com/2018/10/solution-to-02-btc-puzzle-of-310-btc.html)

your links are not working, two times http(s):// in your bbcode. And the second link does not exist on the website.

Thanks for the warning. I overlooked the added "http://". Works now.

OK, it is sad that 310 BTC is taken, but still - maybe I am late for the supper, but maybe just on time for a little dessert :)

Congrats to the winner, whoever he or she is!

So, anyone still working on this, any updates?

I am curious to know that as well. The 0.31 BTC reward is still not claimed yet. I wonder if it's the time for Pip to share some hint(s).

If i have 310 BTC, i invest it on hashing btc asic + altcoins. If freely can choose i buy new USA producted Ford car and put US flag on it, summer house on Saimaa and Lapland.. (20 Ph/s produce garage more profit). Hope that is reality someday!  ;D

Ok, I'm working on something but it'll probably lead nowhere ( like most of you ) . So when is the next challenge, someane on discord mentioned a new 300 btc challenge but i can't seem to find it. Does anyone know?

I am working on the 0.31btc I've managed to find the next salted encryption and bruteforce it, however the output file is another encrypted message that I can't seem to understand what to do next. T_T

you might get a hint if you hash the output you managed to find and submit it in the link below
good luck!

It doesn't give me any clue to what could be the next thing to work about this encrypted data.
The solution to the 0.1 btc and 0.2 btc was already got once you decrypt the password in the salted(encrypted_string) I guess this could be the reason why the 0.31 is still unclaimed. T_T

No body find it :/ 0.31 BTC harder than 310BTC ?

Hello Pip

Would you please make another bitcoin puzzle? thanks

Guys, I thought to bring this to attention of everyone since it appears that Pip is no longer able to post in this threat. He posted an update on his reddit thread called "Introducing the 310 BTC Bitcoin Challenge"

So I am quoting that below:
