Is bitcoin System Vulnerable ?

[franky1]

At the moment there is no 100% "malware proof" system so I guess Bitcoin system is vulnerable too. The question is how.much is realy vulnerable and how likely is for something like this to happen. Having in mind the Bitcoin system structure there is no much chance for such security breach, at least not at the moment.

we should never think of bitcoin as indestructible otherwise people get lazy and dont continue protecting it.
EG one:
it only requires a hacker to use bitnodes website to find all IP addresses of all ~5200 nodes and some possible DDoS/virus tool to delete the historic data before taking them offline all in one swoop.

the chances of that being possible is low. but we should not think ~5200 nodes is a safe secure number to live with. we need more nodes to further reduce risks

EG two:
if all ~5200 nodes were running the code of one implementation, and that implementation has a bug/intentional trojan. again the whole lot goes.

the chances of that being possible is low. but we should not think one implementation is safe to live with. we need more diversity to further reduce risks.

Quantum Computers will cause the demise of Bitcoin. That's my fear.  

quantum computers work differently. and can do some surprising things that binary(regular) computers cant.
but getting a QC to solve a binary computer. restrains QC into certain limitations. which only results in a QC beign 2x efficient in comparison to regular computers when it comes to solving binary logic. ASICS and the amount of ASIC running has already averted the risk QC can pose.
so relax. D-waves QC may be technically faster then many regular computers but is no way near the power of an asic, and no way near the power of all the asics mining bitcoin.

but we should continue increasing the difficulty and adding more ASICS to continue strengthening bitcoin so that other technology cannot overtake in the distant future

I don't know, I have bit afraid about quantum computers, because they can solve in theory things very fast compared than normal computers and the cryptography is little weak in this position.

I hope this problem is fixed,before quantum computers be a reality.

This question is arising in my mind after i did some research.
What will happen if someone brute Force Private keys in Base58 Format ?

And he succeeds then I think he will get admin access to all the wallets and can ruin the Bitcoin.
I know it's very hard to go through the database but It's not impossible either.

Tell me what you guys think about this.

You can't stop someone from brute forcing a private key, similar to how you can't stop someone from brute forcing a password (aside from using something like a captcha). I don't believe that anyone will ever get admin access to all of the wallets.

Personally, I don't worry about anything like that. It just isn't enough of a threat right now.

quantum computers are process for process a couple tousand times better at some solutions compared to binary computers.
quantum can solve non binary problems faster. because they are not binary logic. and normal computer have issues with non binary logic problems.

but when a quantum has to handle a binary logic problem. it limits quantum to the scope of binary logic and so the effectiveness and efficiency is not 100%

so relax.

The only issue I can see with Bitcoin security is going to be quantum computers in the future, and even that is a fairly long ways away at the rate things are going. OP, there is no way to stop someone trying to brute force your key. It will take them a lot of time and chances are you won't get your key stolen.

[ethereumhunter]

there is not impossible for anything in this world even for bitcoin itself. but i think its really need more times to be hacking bitcoin and its need big resource and capability, beside that we should have excellent in programming language.

i really don't know what will happen if bitcoin gets hack because i am not understand about programming language. i only know about how to make money with bitcoin.

I don't think it's that easy to take control all the wallet. We have seen some sites were hacked, but it doesn't mean that all the private key can be hacked so easy as well. in other hand we know that many secure ways to make your private keys secure, so I think to get all people's private keys is difficult.

[lionheart78]

I think Bitcoin system have vulnerabilities, but it is unexploitable at this time due to the limited technology.  There are theories about the quantum computer being able to crack hashes of bitcoin but as far as I know as technology develop, so as the security around it.  It may be possible for quantum computers to crack bitcoin private key at this current bitcoin state but when time came that quantum computers are available, bitcoin security would have upgraded by that time.

By their explanations, you can see that Satoshi is a genius.
Don't worry, mate. Your money is safe here.
Just be cautious on what wallet you are using.

[Roboabhishek]

Yes it's true that until we live we will not see all the private keys being revealed.
How ever if someone gets lucky and generate a Private key of address with 1000+ BTC
Then i think it's only his luck not the exploit of the system.

[MTBTT]

nope i think bitcoin system has been very good and safe if you're clever in securing your bitcoin in a wallet. you will never be stolen
and I have never felt my bitcoin stolen

[harizen]

After that long and deep analyzation, technical aspects, mathematical equations, fearless explanation, thrilling guessed outputs etc. I wondered if there's a person or a group will give super efforts in that kind of hacking activity?

I mean they can think instead to force hack an exchange site rather than whole bitcoin system just to get control of all bitcoins in the world?

If people can use Bitcoins to sell drugs ,illegal Stuff , etc
then i am sure there might be some groups who are potentially trying to hack the exchange website of Bitcoins.
Take the example of Bitfinex Funds Stolen https://bitcointalk.org/index.php?topic=1573336.0

Take a look.

Is bitcoin System Vulnerable? Well, when we say vulnerable, it means if it is open to attack or harm. Harm in terms of hackers, but as far as i know it is strong , why? If bitcoin is not strong then maybe from the past years, it already hacked by hackers but it wasn't done because it is strong. And now it become more progressive and it is safe if you trust it. 

[requester]

every piece if 1's and 0's are vulnerable but we should find out. fort there is no loop hole found in bitcoin system. and it's not fixed that bitcoin system will remain unvulnerable. someday it might get hacked but we don't know what's going to happen next.

[Weeya]

We can't say if the system is vulnerable or not, so we just have to hope that no one will attempt to destroy its security or else, everything will be a waste. All of the earnings and investments will be futile.

[Slark]

I loved posts of Franky in this thread. As always he debunked myths that bitcoin can be hacked with our current tech.

I mean they can think instead to force hack an exchange site rather than whole bitcoin system just to get control of all bitcoins in the world?

That is not possible.
But if hypothetically speaking; if someone will find a way to break bitcoin encryption methods and hack address/private keys or gain access to whole network somehow.
Then how long it would take for bitcoin to crash completely and thus making it worthless?

[Wapinter]

Yes it is possible but given the amount of time it will take,I doubt anyone will even consider to give it a try

[croutonhexagon]

Still not. If it was vulnerable then hackers could have taken all the money. But it doesn't meant that it would remain safe life long. At anytime hacker could destroy the network but it's less likely to happen.

[Mr. Green]

It is not.

If it were, it wouldn't have existed till now.
