Ok thanks for the info, I will try those tutorials.
Are there any cheap hosting plans out there you could suggest for running a node? Maybe some that even accept bitcoins?
Is it difficult to get your node to detect all transactions as soon as they appear on the network?
E.g. I mentioned that sometimes 0 confirmation transactions are missing on blockchain.info but you can find them on other explorers. So I guess it is relevant how you configure it?
You can look for cheap hosting on Low End Box. I've had nodes on 3 or 4 hosts using promotions from that website and pretty much all of them gave me a good or at least reasonable service. You can simply write down Bitcoin on the searchbox and you might get interesting hits  It's a bit difficult to detect transactions ASAP. You need to have your node very well connected. As for the rest, I don't know how to give you a right answer |

That's not definitive proof the account was sold, as was already discussed in this thread. ----- SNIP ----- (I guess you came back after reading my email  ) You sent him an email? Wasn't that probably hacked/sold as a bundled kit with the account? the account+email was hacked/sold it makes sense trying the email route, because the email is in the possession of the person who probably has the escrowed funds, and that's what everyone is after. Might as well forget the "real" master-P in this scenario, because he won't be able to do anything for anyone; he may be dealt with later, the important thing now is getting funds back to people. |

well yes, you are right, I have looked trough this tutorial already. But it does not tell you how to make a call to that server from another page/application outside of that server to interact with that node. Also it does not tell you how to make such calls secure, to prevent someone steal your private keys.
also it could be outdated? I think 50gb of free space is not enough anymore?
Well, you asked for a node creation tutorial  As for whatever implementation you're aiming at, that's up to you, there are no fixed tutorials... The tutorial has instructions on how to communicate with the node. Now your tool must be built around that |

So solely based on capital coming in and exchange volumes you're saying 2016 won't be the most ideal year for Bitcoin? Those two things are just the tip of the iceberg... Being the halving next year a big chunk of that iceberg and miners another big chunk...

Only saw this thread yesterday and now I managed to catch up with most of it... Pretty shocked, mainly because I've had coins escrowed with him for almost a full month up until a few days ago. Well, with him or with whoever took control of the account, if it was indeed sold/hacked. Not yet sure what happened here as there were so far 3 people claiming they are the real master-P (including one signing a message, from what I've seen) and other forum users claiming they have evidence that the account was sold, noone of which was posted as far as I saw (maybe I messed something in the middle of all these posts)
master-P's account "Last Active" was on December 28, 2015, 02:39:46 PM, so he's been around and funds have not moved, as far as I've read. Has anyone tried emailing him? If the account's owner wanted to scam he would simply move away with the funds he was controlling...
I think the hacking hypothesis is the most likely one right now, and the hacker did not manage to get away with the private keys, but I may be wrong.
As for trusted escrows, I do believe that there are still some around here, but that's an opinion for other threads. I'll definitely be following closely this one. If the account is confirmed sold... Well, then this would be the worst escrow scandal we've seen so far around here.

The basics of setting up a node can be found here. With this you can setup a basic node, and do whatever you want with it |

Another vote for Mycelium. Bitcoin Wallet is also good!

Such wow! So many BTC paid! And it says it works on the ad, so it must work... Haha  |

There is a Scam Accusations subforum, maybe you should post there, if you're willing to share the emails you've exchanged with them. |

Now I understand, thank you for your informative posts DannyHamilton, I think most of my doubts are no more. I guess this "puzzle" was meant to be unbroken after a certain point At least we can now see that there are better ways to work for those 32 BTC instead of attempting to break this |

I would think the best way would be to modify (ocl)vanitygen according to BurtW's suggestion. You would need to limit the random number generator to a certain amount of bits and keep the rest.
That would be a start. Unfortunately I do not have the set of skills needed to do that, otherwise I'd start working right away I don't think brute force is going to solve this puzzle.
A GPU bot would increase the performance much higher but still we would be here forever trying it.
The only way to solve this efficiently is to try to find a mathematical formula to break the sequence.
If a formula is not found, I think this puzzle will be as unbreakable as bitcoin itself.
So that means that calculating this is just as difficult as calculating a private key for a given public address? I thought this followed a fixed pattern, since some of the solutions have already been posted by you. All that's left is applying whatever you used to reach those address values. Assuming my pattern assumption is correct then the underlying sequence was masked off to create the private keys.
Now if the underlying sequence before masking came from a cryptographically secure random number generator there is no hope of predicting the 51st private key and brute force or random chance in 51 bits is the only chance.
However if the underlying sequence was mathematically generated then maybe the keys are predictable.
So how were the results on the OP reached? Simply luck? |

I'm not an expert on the Great Firewall of China, but if Bitcoin connections were entirely blocked, nodes and miners within China probably wouldn't even be able to connect to each other. They'd be completely out of the network. But let's assume Chineses miners would start running a fork of their own... Mining would probably come to a halt until they could connect through other means. A fork of their own would damage the integrity of the network and that's what miners rely on for profits, and profits cannot stop. Damaging Bitcoin would be a shot in their own feet...

Or maybe there is something existing?
That was the aim of my post, such a tool probably already exists. |

Suggestions are always welcome.
The brute force way: Start @ ~607809 (multiplied the last known value by 1.7) convert to hex, create addresses, check if one address matches the next in turn. What would be the best tool to attack this in a brute force way while we all think on something better or discover a easier way? |

Looks tempting to crack It does, but I still haven't understand the method/how does one go to attempt and find the solution to the puzzle One thing I noticed:
The first address in the transaction is tagged on blockchain.info with "1st Bitcoin Address Compressed".
So probably this transaction was done by the Bitcoin devs? or even... satoshi?
This hardly has anything to to with any of them. looks really easy to crack
why would reward be so high
Suggestions are always welcome. |

Although Nano does look like a generic USB device, it's really easily recognizeable by someone that was willing to steal you Bitcoins.
OP, to achieve what you're aiming for, the best way to do it is having an encrypted wallet.dat on a regular USB device. I don't think that there are any hardware wallets resembling/mimicing/imitating a generic USB drive

Any info on who published this puzzle and what's their goal? Also, how would one go on about calculating those pvk decimal values and covert them to the private keys? I don't know why but I'm smelling a big scam. Because a newbie that offer more than 12 000€ to solve a following of numbers this is strange...
The OP is not offering anything |

There is, kind of. You need to use the debug console. In the debug console, you can get information about a block using where <hash> is the hash of the block. You can get the hash by using where <height> is the block height. You can also get transaction info by using Where <txid> is the txid. This won't always work since Bitcoin Core doesn't index all of the transactions by default. If you want to be able to search every single transaction in the blockchain, then you will need to enable txindex by adding to your bitcoin.conf file or add -txindex to the command that starts up Bitcoin Core. That seems like a lot of hassle just to do a search. i would be easier just using blockchain.info or something similar. i wonder if they will implement this into later updates. i know its not essential but it seems like it would be kind of handy and convenient to have built into the node. it atleast gives a small bit of incentive to actually run the full node in that you can search it as well. I don't see a need to implement such features on Core. You can use existing websites or setup a blockchain explorer yourself |

Wouldn't happen with Bitcoin. Time for poker players to switch? Anyways, this "too much movement" reason is a bit bogus... Something happening at Bank of America? Or maybe suspicion from where the money comes from? |

You've been doing some quite nice reviews/write ups Any plans on doing one on Ledger HW.1? |
