As I understand it the idea is to have "a lot of people" continuously monitor "a lot of addresses" just in case one of them gets used in the future then, bam, take the poor saps money.

Now that I think this through a bit more, to do this they would have to store every private key they generate (so they can steal the money) plus every public key generated (to match to the incoming transactions in the blockchain) on the very off chance that one of them gets used in the future.  So, the storage requirement is not just the Bitcoin address or public key, it is at least all 256 bits of the private key + the public key(s) for pattern matching.

I'll just post it on his behalf...

11cea-1h

Message and amount verified.

2010-08-08 03:58:48 is the date/time to beat.

About 5 days from now I will close out this contest unless we get a lower MinAddress.
1643  Bitcoin / Project Development / Re: 2^256 Deep Space Vagabond on: September 23, 2014, 10:11:24 PM
I will use 32 bytes per address (25 bytes per address) in my response.  Storage of addresses will actually take more than that so rounding to 25 is in your favor.  I will also give you binary megabytes, terabytes and petabytes of storage which also works in your favor but makes the math easier.

Or better, just over 1 PB worth of data storage and we managed to nab a few transactions from the blockchain already.
Just an empty claim until you prove it.

1 binary PB = 250, 250 bytes / 25 bytes per address = 250-5 = 245 addresses, 2160/245 = 2160-45 = 2115

Which means that for every one of your 245 addresses you have generated there are 2115 addresses you have not.

Next, it has nothing to do with basic math, there is nothing basic about the math behind any cryptographic function.
Multiplication and division, adding and subtracting of exponents is very basic math.

Lastly, who needs 50% of the addresses? if a few thousand people had a few quadrillion addresses each it makes up a large enough percentage that a person is no longer chasing a moving target. It also means that every time you move your bitcoins, you have to wonder...... Has someone got the key for this address?
Not exactly sure what you meant by "a few thousand people" or a few quadrillion addresses so how about 4,096 people each with 16 binary quadrillion addresses?

212 x 254 = 212+54 = 266, 2160/266 = 2160-66 = 294

So for every one of the 266 addresses you have generated there are still 294 addresses you have not.

Ask yourself, how many bitcoin supporters are going to feel comfortable with their investment knowing that 15%, 10%, 5%, hell eve 1% of all bitcoin addresses are indexed and monitored. (the fed has already done this, that is where this project stemmed from)
You will never get even close to 1%, lets call it 2160/27 = 2160-7 = 2153 addresses, never.

No the fed has not done this.

Imagine everyone involved in crypto currency to date had the ability to randomly generate addresses using the same faulted PSRNG system that 80% of wallets use and fill even 100 gigs of space on a hard drive. How comfortable do you feel with your investment then?
Faulty random number generation is bad, very bad.  However it is faulty random number generation, not a flaw in Bitcoin itself.  If true (that many addresses were generated using a faulty random number generator) then thanks for pointing that out.  I use hardware random number generation so I feel pretty good about it.

Imagine as hard drives and storage become cheaper, As is we are already buying 6TB drives for $190usd. You can already go make a $70 investment and buy a 1TB external. With our software's it would take maybe a week for you to fill it and monitor it in real time. take that multiplied by even a thousand, and growing daily. How comfortable are you with your investment then?
Very comfortable, due to the math showing that is a very small amount of the total address space.

Imagine next year when Segate launches its first 10TB 5,200rpm HDD for only $350. (already in the works) Thats pocket change for most of us here....... You get the point. How comfortable are you with your investment then?
I am working on a 40TB drive, so what?  Still nothing compared to the entire 2160 address space.

If you can honestly say that you still have no worries about your bitcoin after taking all that into consideration, then you sir are an idiot with no common sense.
No, I am an engineer using a hardware random number generator who understands and can do basic math.

Granted we are not giving you the WHOLE story yet, waiting on a few final developments that will make it all more platform neutral and basic user friendly so we are not just talking about it but letting everyone do it. But in summary, about a year ago, we were where you are now. In the very recent past, we have hijacked about 3.3BTC from a total of 5 addresses.
Can't wait for your WHOLE story.  Can't wait for you to prove you have moved 3.3 BTC with your method.

Developers who want to join the team and help spread awareness get the source now pending their contributions as well as a basic overview of how it works. The rest will have a beta platform within the next month or so to start cataloging their outputs, in a few months anyone who has some hard drive space that wants to catalog some bitcoin addresses has a chance to play along.
Sure, I am a developer with 30 years experience working on hard disk drive firmware.  Send me your information packet and I will take a look at it.

Final disclaimer,

Yes, if we find bitcoins we are taking them but this is not about being thieves. its about making people aware that 75% of the hype about bitcoin security is FALSE, even by the admission of some of the current bitcoin core developers. A direct quote from one of them in a recent interview "It is scary how many people have invested so much money in such a young technology that is filled with security flaws". We ourselves could not possibly steal enough bitcoin to make a difference, but as a community (full of thieves anyways) we could chip away at it and tally up enough hijacked coins over time to force the hand of the developers to assess the important and most prominent security flaws NOW before it drives bitcoin into the ground.

If you want to troll, go for it, we all love a good laugh and 80% of us on this forum are only here to see the dumb stuff anyways. Otherwise, just hang on and we will get you software soon so you can participate and put some of those old no longer used hard drives to good use.

BTW: Yes Hyena's laugh, ever wonder why? THEY ARE THE BIGGEST THIEVES IN THE ANIMAL KINGDOM
Question:  why not start a new thread now?  What is stopping you?
1644  Bitcoin / Project Development / Re: 2^256 Deep Space Vagabond on: September 23, 2014, 04:49:46 PM
Amazing to see the community pulling together to finally point out a serious weakness in Bitcoin. We. the Hash Hyena's have been hiding in the shadows for a long time for developers to put their talents to use in forcing hard fixes to some of these weaknesses.

Thank you to all of you developers for your efforts. We do not care how much a misinformed community may laugh at the probabilities, and big numbers like they mean impossibility. Its real, it has happened, and it will continue to happen.

For any developer that would like the proof, and like to join forces with the Hash Hyena's on the "Hash Hyena" project to further development on our new platform that we intend to open source and soon release to the world please message us directly through BitcoinTalk.

For the rest of you, If you want to get leaps and bounds ahead of everyone else in the game when we officially launch the Hash Hyena software do these two things.

1: start stocking up on hard drives. The more storage space the better. ( we currently have 1.18PB and growing )

2: run the line of code below in vanitygen, make tons and tons of output files and start storing them, we will soon release the program that converts them into .csv files that we use for importing. The more files you have when we launch the further you are ahead of everyone else when this all goes public in a few short weeks or months.

Code:
vanitygen64 -k -o output.txt 1

We will be releasing a batch file for those of you with high performance CPU's to run multiple outputs at a time in a nice little packaged .rar download. We will be starting our own thread soon
Hyena?  Do you mean Laughing Hyena as in this is a total joke Hyena?  Or, worse yet you are serious and just not very good at basic math?

To answer a question that has been asked a few times.  This analysis only used the electrical power and estimated cost of that power.  The cost of equimpment is ignored.  Basically the cost of equipment, infrastructure, etc. will effectively reduce the power consumption of the network so this is an estimate of the maximum power the network will rationally attempt to consume given the price of BTC.  In practice it will not consume these numbers due to these other costs factors.

What if blockchain.info goes down is my wallet lost then ?

unless you have a backup.

I dont have any backup of my wallet. I only have the private keys written. Am I safe ?

There are a lot of if's here, but if you're sure it's your private keys that you wrote down, and if you're sure there are no typos, and if you never add any new receiving addresses to your wallet, than you should be safe.

Edited to add: and also if they're either unencrypted, or you are sure you know their password.
I had the same thought:  are you very sure you know you have your private key written down and not something else (public key, Bitcoin address, etc.)?  Also you must have all of your private keys, not just one.

Where did you get this number you are calling your private key?  How did you get it from the blockchain.info web site?

I should not have used the word written as I have not literally written them down anything with pen and paper. I'm not very sure what encrypted/decrypted things u r talking about regarding private key. I have used only one address on blockchain.info and have downloaded the paper wallet, which is a PDF doc, from their wallet dash board. That PDF has the address and the private key written on it.
If all true you are golden then, that one private key is all you need and you can sweep it into any wallet on the market pretty much.

If you want the "fun" of mining and don't want to buy coins directly, you could buy some mining contracts.
Hold on.  I can see mining for "fun", learning Linux, how to set up GPUs, configuring hardware, pool selection, connecting to the pool, etc.

But if you just go and buy a mining contract how is that "fun"? 

Wouldn't it be more "fun" and produce the same financial result to instead take the money you want to invest in mining contracts and then flush say 15% of it down the toilet?

At least then you get the "fun" of watching it swirl around on the way down to the sewer.

Looks like FF and Chrome store history of paper backup made with web wallet.

BE CAREFUL!

You also have to be careful of the printer itself as many printers store copies of the images they print.

I just tried searching my tx on all the other sites, says invalid, although the btc isn't in my blockchain.info account anymore.... affff
Can you search for the Bitcoin address you sent the BTC to and see if the transaction shows up there?

Can you search for the Bitcoin address you sent the BTC from and see if the transaction is there?

Do this on some of the other blockchain explorers mentioned above.
1651  Economy / Service Discussion / Re: No block in 8 hours. on: September 19, 2014, 09:41:41 PM
I really like and highly suggest deterministic wallets because they do not need periodic backups.  That is very nice for forgetful people like me.  I just back up the seed in a very secret and secure place and never have to worry about backups again.

So in answer to the questions in this thread "what should I do when I abandon blockchain.info" I would say use a deterministic wallet.

Trezor is my favorite however it is a hardware wallet and it cost $119.  If you don't want to spend money for a hardware wallet there are free software deterministic wallets (Wallet32 for Android, etc.)

EVERTHING is reversible, it's just a matter of how difficult.

Even a cash deposit into a bank account is reversible if the person depositing is quick enough, and meets a teller lenient enough. If you meet someone face-to-face for a cash transaction, there's no telling that he'll mug you later after he hands you the cash and you release the btc.

You also have to worry about counterfeit cash when dealing face to face.

Localbitcoins and face to face is not as secure as people make it sound. So many things can go wrong.
Yes things can go wrong and you have to be prepared for them.  Meet in a very public place.  Use one of those markers that detects counterfeit bills, etc.  I have done hundreds of face-to-face transactions with not one issue.

Advice to all current and future alt coin supporters:

If you want hard core Bitcoin supporters (Danny, me, others) and all other Bitcoin supporters to take notice of your new alt then, in addition to all of the great "improvements" you put into your coin, simply use the initial coin distribution method described here:

https://bitcointalk.org/index.php?topic=563925.0

This will:

prove to everyone it is not yet another pump-and-dump
get all Bitcoin holders on board, invested and interested
give your alt coin a chance in hell of becoming something other than just another has been want-to-be footnote in the history of crypto currencies

Until that happens I personally will not be interested in your alt coin.

There's no such thing as a free lunch.  Tongue
Maybe, but there sure is such a thing as a totally worthless pump-and-dump alt coin, many such things.
1654  Bitcoin / Bitcoin Discussion / Re: Who actually spend bitcoins ? and for what ? on: September 19, 2014, 06:19:58 PM
I have bought a lot of things including gold, silver, girl scout cookies and my laptop from Dell.

Did you buy those girlscout cookies from BayAreaCoins? Cheesy
It was a few years ago, don't recall exactly who sold them to me, it was one case of the thin mints shipped directly to me.
1655  Economy / Currency exchange / Re: What are some completely irreversible payment methods? on: September 19, 2014, 06:17:40 PM
Never heard that Paypal sent as gift can be chargebacked .
still you have UKash , CashU , Paysafecard , safe 100% .
It may be true that you were under the impression that paypal gifts cannot be reversed (they can) but how on Earth do you explain your inclusion of MasterCard in your list of safe payment methods?  Credit cards are, by far, the easiest payment method to reverse.  Often times all you need to do to dispute a charge is log in, find the charge and check a "dispute this charge" check box and your funds are immediately reversed.

you mean methods where there is no Chargeback ? you can't chargeback Paypal (sent as gift) , Paysafecard , Wester Union , CashU , UKash , MasterCard ....
BULLSHIT

PayPal even as a gift, MasterCard and all other credit cards, bank transfers and almost all other forms of fiat can all be reversed.

I only sell for cold hard cash.  It is the only form of fiat that is certain to not get reversed.

localbitcoins.com doing an in person cash for BTC deal with a highly reputable dealer is the only way to be certain.

I bought some of the earliest coins.  Here is one I opened in order to make sure it worked before I bought a whole bunch of them so I think it is my oldest physical coin:

233b5-114c

I don't think dooglus has to worry about physical Bitcoins.

igorr, do you still have a short position?  It seems to me that if we don't get support here in the $400 range you could be in for a pretty wicked additional profit on your short position.

After $400 where is the next price support?  $340?  $300?  less?  Very hard to predict.
