Bitcoin Forum

Since the begining of this century, NSA has invested billion dollars in some secret activities to keep its ability of eavesdrop and taken this as its great mission. If the information from terrorist, foreign spy and other foes, US will be the one to attack.
It is said that NSA cooperates with multipal technology companies to use high speed computer to crack secret codes. This institue has decoded the encryption skill of protecting global business and bank system, kept the business secret,medical record and other sensitive data, at the same time, the safety of emails, internet surfing, online chatting in US is automatically protected.
An intelligence budget file has shown that this kind of action is still going on. The American national intelligence supervisor James R. Clapper Jr. has written that:"We have invested a lot of funds on breakthrough password analysis to attack the password technology and network traffic of foes."
There is rumor in the past that Bitcoin is one of the institutions of NSA.However, all the details around the national institution have shown that Bitcoin community has become the goal. Many people in Bitcoin community believe that NSA is cracking the Bitcoin agreement, which is one of the great tasks for them.

what bitcoin agreement is that?

Good try, but i bet them will failed to crack bitcoin.
Sure there is nothing absolutely safe, but the security can be updated.

I don't really get your mean by crack Bitcoin :-\ , the coding of bitcoin has been done in Sha-256 for a reason , it being it can only be encoded and not decoded. What they can do is brut-force their way to the correct statement and then hashing it and matching it with the original one. And to stumble on such will take several Years , might take less if you're lucky but that's a low chance gamble.
They have said decoding passwords and codes, there might be something else supposedly , but not Bitcoin.

Never keep huge amounts of bitcoin in one single address. That's the best solution. Don't make yourself a target.

It's probably more of importance to them to de-anonymize Bitcoin users than it is to actually crack Bitcoin private keys.

Well I wouldn't be surprised if they really are trying to crack cryptography in general, Bitcoin would then be just one of the affected techs. It is not possible for anything designed by man to be truly irreversible because you always know the starting point. Any induced state can be traced back to it's starting point (original state) because the path between the two is always clear and well defined. Cryptography is not unbreachable, it's just that at this time there is no known method for reversing the process.

they can't crack anything unless they have a super quantum computer prototype or something like that

another "fud news" to bring bitcoin price down

They cant do that if they do that bitcoin users get angry and the bitcoin will be close for a min time. This will affect economy of the coutry that use bitcoin and also the different business that accept bitcoin

Listen to the stuff that Applebaum and the team at Tor are saying... They have access to ex-NSA agents, who revealed some methods used by them to spy on people.

The NSA says, they are collecting ALL data, and then they target strategic key targets from that database. {If they suspect someone}

They need to have access to the information linking a person to a Bitcoin address... not access to the Bitcoin address itself. {To track the money flow}

It would be great, if they could intercept the money or hack the address, to prevent the money from getting into the wrong hands... but that opens up a whole new can of worms.

For now, I think, they will target only the person behind the address...  ;)

What kind of FUD is this?
And what Bitcoin agreement are you talking about?
There is NO Bitcon agreement.

There is only a protocol.

This sounds like some conspiracy theory.

I mean, with regards to the threat of government seizures, yes, bitcoin is vulnerable, but so is gold. There is a certain confiscatory risk, like what happened in 1933-1934, where US govt. made it illegal to privately own gold and confiscated it, first by executive order, then by Congressional decree.
There are ways to buy bitcoin so that your identity is not traceable via the bitcoin blockchain, but I think NSA is more interested in being able to trace wallet-holders moreso than cracking the blockchain.

What good will it do if they "cracked" bitcoin? They can take your coins, that's it! They don't need money, taking anyone's coins is not their objective. It is more of their interest to monitor, follow the coins, and pinpoint where the crypto-fiat exit node is for money launderers and terrorists. To do that, they don't need to crack any encryption.

If they have truly attempted it, then it would be bad for Bitcoin.
I think it is going to lose a lot of it's supporters.
Who wants the NSA to know what they do with their money?
 

Just keep multiple wallet with your balance spread out among them. If one wallet gets cracked, atleast you'll have the rest of your money safe.  :)

Multi-sig might help too. But I still don't think they are actively trying to crack private keys...

it will be take hundreds of years to crack Bitcoin so i don't think that attempt worth of it because of Sha-256, that thread look like a FUD and doesn't mean anything more. ;D

yes agreed with you that is just troll, i do not believe they can crack the bitcoin in the current century.

If they can do this then they will break the principle of bitcoin , "anonimous transaction". I believe satoshis has thought about this before creating bitcoin and the sha256 hash is vulnureable if NSA spend some resources into trying to crack it

We all know Sha-256  is safe today, and MD5 is safe before it was cracked.
So the sha-256 still have the chance to be cracked except brutal force crack.

IM curious about what happened if they craked the bitcoin? They can get a bitcoin? Or get a bitcoin to every address?

How exactly is the NSA going to crack Bitcoin?
I am really curious.
I would really like to know what kind of alien technology they will use to accomplish that?  ::) ::) ::)

If they cracked down bitcoin now, they will get free to control the movement of bitcoin and we are doom since the bitcoin has been controlled over but on the other side bitcoin has a chance to grow higher enough. Thats what I think but still bitcoin havent been cracked right so we can just relax for now

I do not think they can crack it unless,
they have some sort of a backdoor in Sha-256.
I believe they have done something similar before.

First NSA had already broken Bitcoin, now they are attempting to break it? Are we going backwards in time?

So what do they got after they break it? And why OP ask the same question again? Will NSA break this again for the second times?

No, they are just assumptions, but people got their assumptions backwards, I guess.

I think the OP is just trying to spread FUD.
Nobody told him that Bitcoin doesn't get any cheaper than this.
Buy now before the price rises.

So they just do speculation right? Because there are so mant threads that talk about this things but never get to a conclusion. So they havent break it for the first time right?

They can control the bitcoinbitcoin so they can put the bitcoin in their want address or less they can move the bitcoin from your address to his address? Thats what i thinking.

The code is open source, there's nothing to crack.

FUD

i hope it's not true... because if they want.. they do ..  :o

quantum computer.

This.

What is there to crack? It would be a greater use of resources for them to explore the blockchain and get familiar with tracking transactions and how to use the blockchain for other things.

Agree, it seems as obvious target. Cracking Bitcoin Private Keys is kinda impossible from what i red.

It would be even cheaper to build some (or some more) miners and "kill" bitcoin by not including transactions in solved blocks.

I would like to know how one "cracks" a virtual currency.

Hahah why us? do you want to lose your btc? you giving them an idea. :3 If they do that and they success promise me many of users will lose their bitcoin.

only work on ecdsa not on sha256, and i'm sure using a quantum computer to break an assets(bitcoin) with a joke marketcap, it isn't worth it at the moment, i believe their quantum computer is super expensive to make, if they ever hold one secretly

It is not the same with what you know of the usual cracking. What it means is that the cracking will only decrypt the hash and so that the NSA could track on every single transaction of it. This is ofcourse against the principal of bitcoin , anonimous transaction.

What exactly is different between breaking and cracking Bitcoin? Isn't this basically the same thing. If you crack it you break bitcoin algorithms, right?

I think that break is going for the security and cracking is for the code but I dont know what are they use that for? Are they going to take full control or not after break into this system. That is need explaination

Maybe the breaking thay he said is to break the vulnerability of bitcoin to crack the code so that they can control the movement of bitcoin or they can send the bitcoin to their address. I only guessed that.

If they can crack mine, they deserve the 20 bucks I have in my wallet https://i.imgur.com/jhVy1d9.gif

Why they need your 20 bucks? Your 20 bucks is not worth for them, they aim bigger. If they can crack bitcoin then your buck means nothing to them and they have the power to control all of bitcoin in this world

Damn... They're on to me...

hahaha dont estimate 20 bucks theres many thing you can buy in 20 bucks its still money. but you are correct they hunting the bigger bitcoin. So that they only snob you because if they stole 20 bucks and they caught the punishment for them is equal to the punishment to the man who steal a million or a billion, so they hunt the bigger one.

Of course, but if they crack him it will be to easy for them and the price is just too low. If they cracked bitcoin its harder and the price is worth to get so dont judge from the punishment, they will try to get it and delete their track from bitcoin so no one will know it

All NSA has to do is leak a rumor that they've cracked bitcoin, and the damage is done. That said, personally, I think it can't be cracked.

Now no system is safe. Even if you are scammer or hacker your vpn can detect or can trace because security is just imaginary conceptbecause if it is true no security system will be hacked.

well i don't agree that NSA can crack easily the whole network of Bitcoin if they are attempting to crack, this can take several years because of SHA-256 and i don't think it can worth of it after wasting of so many years to just take control the network these kind of talking looks like troll so i don't take this serious.

Of course they are. NSA is trying to crack everything, literally everything, but it's a losing game trying to crack BTC, it's physically impossible, unless they are doing exactly that, trying to come up with a quantum physics computer (absolutely sci-fi and pointless trying to think about that happening).

we can only assume like this, because we have not been able to get a real and concrete evidence on this issue.

Yeah i also thinking that is troll because no one will create a crypto currency that so easily to crack the code or break the vulnerability. And Satoshi wont do a simple machine that involves money or an internet money that can easily hacked.

they are spreading fud as usual, so here the one that want to "kill" bitcoin(answering the qustion of the other thread) the nsa

you don't need any evidence sha256 is not crackable ever, it go against the laws of the universe

I think theres no impossible in this world theres a time that the bitcoin will be hacke remember no system is safe. Any security can be cracked if not now, but theres a day that the word security will be removed from dictionary.
