waves on
Waves on Bithumb is a great news! If it happened last year....do you remember last year when Monero got listed on Bithumb? It went crazy, like 2X in a couple days but it was anothe time, Bithumb was among the top exchanges in volume
precisely, this is a great opportunity for traders to dig into the waves. They seem to be growing and glowing in the exchange it.

Yes!! ride the wave!!

This makes it more of a pain in the rear to operate any kind of Bitcoin/crypto-currency (or other virtual currency) exchange if you're based in the U.S., at least in a complying above ground way.
It means that you can be pretty certain to have a way to run a Bitcoin exchange in the US without being thrown in prison for running it.

Not that I think they will succeed though. I just find it unlikely that someone wanting to hurt bitcoin would use Ddos as the only attack vector ?
It depends on the power of the attacker.
DDoS are a relatively cheap way to attack.

The highest bidder winning and so buying the right to make that decision. The mechanism may be different but along similar lines, how much tax would it pay for?
It would allow someone to pay for a law that taxes X to fund Y. As a result you would get more taxes not less.

I dont think wheteher you feel for or against Israel is the point. I bet Israel and Iran would unite in an article critical of Bitcoin. The point is most every article and evey mention on tv about bitcoin seems to present only the most negative of its possibilities. Should we all establish second identities and start at least e-mailing those orginaztions back with the positive side of the story.
It's pretty hard to tell the positive story in a way that can be told in a establishment friendly newspaper or TV show.

If you can actually craft a story that works mail it. If you just want to mail them your positive personal view of bitcoin it probably won't do much.

What I was thinking about in regards to other virtual currencies (p2p crypto for example) was what if a big player like Google decided to make their own version of bitcoin and due to their large stuff full of smart people they were able to make it very easy and painless for the average person who never even uses computers. 
Google is a company that tried to get money transfer to websites that support copyright infringement stopped.

They have no intent at all to provide a service that support annonymous transaction.

However, Google et al are entirely in the pocket of traditional businesses. They earn huge advertising dollars. That is their market.
Google is trying to sell content with Google Play. They want to get good deal with major labols to sell music and films.

Defending against 51% attacks
by
ChristianK
on 20/04/2013, 21:41:53 UTC
At the present bitcoin doesn't have any defense against a single new miner with 51% overtaking the network.
That isn't necessary.

How could bitcoin defend against itself?

Every miner should sign the blocks that he solves with his own key. After a miner has created a lot of blocks
over month that get accepted by other miners, new blocks of the same miner deserve more trust than blocks
of new miners.

How do you defend against one established miner using this new voting power to attack?
Allow every client to make the choice to distrust a miner. If a miner attacks the network than the community
can decide to distrust the key of that miner.

Open and transparent is what Google wants. This wouldn't be a problem if we didn't live in a world of corrupt authority, corrupt cops, frame jobs, set ups etc. Julian Assange being accused of rape and it's open so even if he's innocent his reputation is ruined?
Julian Assange's own story of what happened in those two night isn't open. There also various other information about the issue that isn't open.

Shhhhh... don't give them ideas! It is not just Google, even Facebook, Twitter and and all sorts of other sites could pull the rug under Bitcoin's feet if they decided to utilize their user base. The coins would def be different in terms of the technicalities, they certainly would not require mining. I think the only plus(for us) is that most big companies would probably be to stubborn and would make the coins centralized around there own branch of companies similar to how gift cards work.
Facebook actually has it's own coins. The same goes for Amazon.
Quote
If Google, Facebook, Twitter, and Yahoo all tried to start their own cryptos, they would all try to 51% attack each other. Nah, better they mine Bitcoins. If any of them tries to 51% attack Bitcoin, the others would defend Bitcoin to make sure they don't profit unfairly.
I don't think Google would design a crypto-currency in a way that it can be effectively 51% attacked.

If you are Google and actually can sign things with Google certificates, why rely only on proof-of-work for trust?

In an age where an attacker can rent a botnet of 1,000,000 PC, you don't want a function that can effectively run on a normal PC.

I dont think you even need a lot of money for that, the grey/black hat hacker just does it as his own project...  There ought to be some really serious scrutiny of every byte every check-in.  Maybe bitcoin should think about paying a bounty for the bugs out of some slush even.
Who's that bitcoin that you want to pay a bounty?

If you were Satoshi would you tell someone who has a habit of publishing every scrap of information he has to the entire world no matter what the comeback is? He would be the last person on the planet I'd tell.
I don't think you understand Assange.

Assange didn't publish the identity of the people who left Wikileaks along with Daniel Domscheit-Berg to found OpenLeaks, even through the OpenLeaks folks took a harddrive of valuable data with them that they afterwards deleted.

It works like this: Trusted parties could send some kind of random amounts of bitcoins from one seemingly random address to another both controlled by the same party or one controlled by another trusted party.

Yes, they are. This is what being a developer means in this context: that you are a servant. A slave, if you prefer that terminology. One who obeys. An inferior. A steward. Nobody, politically speaking. I'm running out of alternative ways to put this, but I would hope you get the idea.
I think you get that wrong. Being a developer in no way implies that you are a serve.

Lead developers in open-source projects get titles such as benevolent dictator.

In the case of bitcoin, the lead developer gets payed by the foundation and the foundation has a bunch of important stakeholders in it. The foundation together has probably the political power to do anything with bitcoin that it likes whether or not you approve.

I agree with those who push for a formal specification for the protocol instead of letting the reference implementation be the protocol. It is hard work, but the way to go IMO.
Are you willing to pay for that hard work to be done?

You're right, it's clearly impossible to do.  Nobody has ever written an open source p2p protocol that has changed.  Or they could just inform people that the network is still in it's infancy and as changes are made nodes that do not upgrade will be dropped.  Kind of like the mandatory 0.8.1 bitcoin client upgrade.
That update allowed some people to engage in double spending. It not an example of a seamingless transition.

Ripple enthusiasts are too smart for that, and Litecoin users are too stupid.
Don't forget that Litecoin is essentially a coin that's build to be easily mineable with botnets.

Quote
Yeah, what system does Slashdot use? Or CNN.com? (any major news website, most are immune to DDOS).
They aren't immune. They are just big and therefore expensive to attack.
Even banks can be attacked : http://www.informationweek.com/security/attacks/bank-ddos-attacks-resume-wells-fargo-con/240151825
The folks that attacked those banks weren't even all that powerful. Just one random group of angry hackers.

The problem is more systemic. For example, there are DDoS extortion cases where it's less costly for a victim site, like a profitable gambling one, to pay a ransom then suffer extended downtime.
MtGox is effectively a profitable gambling site.

Re: Why any ordinary person would be interested in Bitcoins?

The kind of person who describe isn't an ordinary person. There are much more Mr Zhangs than Mr Smiths. Half of India's population has no bank accounts. http://blogs.wsj.com/indiarealtime/2012/11/01/why-few-indians-have-bank-accounts/

There are many people in this world who have cell phones but no bank accounts. In ten years they probably have smart phones.

Those people might want to do low-wage online work and get payed despite having no bankaccount.

A lot of bitcoins economy will however still be illegal payments. Some third world towns that make their money through the drug trade
might switch to using bitcoins for their regular transactions as well.
