That is silly. Just because there are time delays in terms of deploying the necessary software and/or infecting new machines with the necessary software doesn't mean that it won't happen. It is actually perversely good for bitcoin in a way, if those that have large numbers of machines at their disposal have an economic incentive to strengthen the network, rather than attack/undermine it.

So why hasn't it happened yet? The clever controllers of botnets surely have heard about bitcoin by now?

Actually if a botnet had a million PC's, you wouldn't need 20-50, you'd only need one to exceed the hashing power of the network. The fact that it hasn't been done yet means it's not easy - that's unlikely to change, so I'm confident that it won't be.

I am convinced that Botnets will destroy mining by conventional means.  Innovation, (though illegal) will kill conventional miners.  The incentives are just too high.  1,000,000 infected computers (not hard to achieve at all with a Botnet, in reality the more successful Botnets have 10 million or more) will drive the difficulty through the roof!!!

Botnets to Bitcoin is what GPU's were to Bitcoin 9 months ago (less the illegal part).  The smart ones are packing their gear and selling off now.  I just shut down a 26gh network and now with the help of friends we are packing it up and preparing it for shipping, for sale.

While Botnets are illegal as all hell, that will not stop people.  Again all you need it 20-50 successful Botnets running to shut down the miners of today.  So that’s 20-50 people WORLDWIDE operating their individual Botnets.  Do you really believe that there are not 50 people on the planet that have the know how to do it, and would not do it.  Do the math people.

I was wondering why on deepbit they don't show stats of what users are doing how much MH/s. At least I couldn't find it and most pools show that info.

It would be interesting to end up with a totally legitimate project, that due to factors not under its own control, is completely facilitated through infected computers. What's more sci-fi than a peer to peer crypto currency that is mined and verified by the computers of people who have never even heard of it?

Most of the large pools have a tremendous amount of CPU miners -- those are almost certainly 90%+ botnet.

But, yes, between botnets, people running server farms at home or school, etc, I think mining will be unprofitable for most people - even taking into account only electricity, not even hardware depreciation, within a few months.

I'm not saying that they're want to or that they could profit from it, but it's a real possibility.

The same possibility exists concerning pool operators, right now. Slush + Deepbit have more than 50% of the computing power. BTCGuild is also huge. They wouldn't have much trouble to coordinate some attack, if they wanted to. But if even them, which only get a small share of what is mined under their pool, don't have an incentive to double-spend, imagine a botnet owner who would get 100% of the mining returns if doing it honestly?

Double-spending through a >50% attack is not cost effective. The incentives to be an honest miner are much stronger.

If we should worry with a >50% attack, that would be a politically-motivated one, with the intend to pause the network for as long as they can at the expense of some taxvictims. And even that is not very likely either.

A botnet CAN be against the will of the owners.

That's just plain wrong. Please inform yourself before posting nonsense.

BTC itself is a Peer-to-Peer network. A Botnet is a network of infected computers, controlled by one or a few persons remotely.


has anyone ever considered that bitcoin pretty much is a botnet itself?

No, because this is stupid, see above.

I mean, really, people, you are all doing distributed work which is controlled by a piece of software over the network.

Peer to Peer != Botnet!

I can only repeat: Inform yourself before posting.


Anyone hearing a bell ringing? The only difference is that most Bitcoiners run the software willingly.

And that's a huge differance. A differance between 10 years of jail vs a well-used open source project, for starters.


It's hilarious how you're even quoting wikipedia twice, but fail to read (or understand) the very first sentence:

Quote
A botnet is a collection of compromised computers, termed bots, that are used for malicious purposes. A computer becomes a bot when it runs a file, typically from a drive-by download, that has bot software embedded in it. Botnets are controlled en masse via protocols such as IRC and http.

To translate from the german wikipedia entry for botnet:
Quote
A botnet is a group of software bots. these bots run on networked computers, whose network connectivity and local resources are at their disposal.

One other from the english wiki page:

Lots of Dells and Apples and HP's used by average Joe's have Radeon 5xxx and 6xxx cards in them, but I think you missed my point.  I'm thinking of 6 months from now when, if BTC doesn't appreciate significantly, mining won't pay for the electricity required to do it.  At that point, if the computational growth from legitimate miners slows or goes negative, and mining becomes mostly a botnet business, those same folks will have the power to turn BTC upside down at will.  I'm not saying that they're want to or that they could profit from it, but it's a real possibility.

I agree.  If the difficulty level is adjusted to keep an average rate of 1 block every 10 minutes then the number of blocks created is 144 blocks/day regardless of the number of miners.  At $20/BTC and 50 BTC/block, that's $144,000/day.  That is then split among the total number of miners relative to the amount of processing each does.  With perfect information and perfect competition, equilibrium is when the costs of GPU and electricity are equal to revenue from Bitcoins.

With a botnet this breaks down completely.  The cost of GPU's and electricity to the herder is zero, so the number of miners from botnets will continue to increase without bound (economically).  As the number of botnet miners increases or the value of a Bitcoin decreases the number of legitimate miners will decrease to maintain equilibrium.  Botnets could conceivably have incredible amount of power.

BTW.  This also implies a minimum transaction cost that must be maintained when Bitcoins are no longer created.

We know botnets can get really big if they're run by clever people.  The question I have is, if someone creates a clever botnet and turns it on once mining has become unattractive financially to those who pay their own electric bills, isn't getting over 50% pretty feasible?

If a botnet guy would get over 50% network power (which I found unfeasible since machines with decent GPU performance are usually not in the hands of computer illiterate people), they would already make so much money off it that they wouldn't even need to cheat. 1000 btc roughly every 2 weeks, that's between 10k - 20k USD depending on how the price will move after mtgox reopens.

Yeah, what I meant was "How is that an attack on 'the bitcoin net'"? It's not.

In theory, if a single botnet/coalition of botnets gained over 50% of the network, they could start double spending.

Otherwise, they are just hardening the block chain.

There's a little differance though as running a Botnet is against the will of the PC owners and probably also against law of most countries Smiley

True it's a millionth of a taste though of what compition in the future will be like :-)

An attack against "honest miners"? Is that you FDR?
It's competition in the free market, it forces efficiency and lowers prices. Fighting it with anything other than innovation is neither fair nor honest.

there are a lot more annoying things a botnet can be used for, if every single botnet in the world would only be used for mining the world would be a better place!
