61  Bitcoin / Bitcoin Discussion / Re: 47% of Americans want to make purchasing goods and services w/ Bitcoins illegal on: April 08, 2014, 08:23:31 PM
As a selfish american, I would vote that it be illegal.

Why?

Because allowing something like bitcoin to have power gives poor countries more power. Right now the dominance of the world's major currencies gives the US and other 1st world countries huge power over trade.

I'm also currently involved in a business that benefits from government manipulation of exchange rates (the fact that china suppresses the Yuan's value vs the dollar saves me thousands of dollars a year).

From a purely financial standpoint, I benefit from the current corrupt system.

Why are you filthy rich or a politician?

Because fiat money is not good for you if you're not. In fact you are working most of your lifetime for the benefit of those groups. This is only partially offset by the USD worldwide ripoff.

You realize politicians are mostly bought and paid for by corporations right? Yes, things like high tax rates piss me off, but that's more then made up for by the money I can make off the backs of people being paid less then a living wage, which is made possible by the government.

I don't feel like I'm getting the short end of the stick with current system, so I'm fine with it.

Would you stop "benefiting from the current corrupt system" based only on the fact you could/should make money more honestly?

I make my money legally.

Correct me if I'm wrong, but forks are only possible with a certain amount of hash power, and to gain enough hash to fork the Bitcoin chain would be very expensive and thus impractical.

yeah you're wrong.

Forks happen anytime 2 miners solve a block referencing the same previous block.

65  Bitcoin / Bitcoin Discussion / Re: Will US government disrupt Bitcoin? on: April 07, 2014, 08:04:43 PM
Yes, not because it'll pose any real threat to the central banks, but more because of bitcoin's association with crime, and association with anti-government, anti-central bank people.

Look @ the liberty dollar. They trumped up all kinds of charges because the founder spread all kinds of anti federal reserve propaganda.

There's tons of other sellers of gold/silver coins/bullion that never get harassed, but this guy was dumb enough to let everyone know how anti-government he is.
66  Bitcoin / Bitcoin Discussion / Re: New attack on the bitcoin network. on: April 07, 2014, 04:17:39 AM

The fuck are you on?

If anything the reward for mining for an "unethical" pool would be higher, if only slightly.

Every tx you add to a block slightly increases the odds of it being orphaned. So if a pool say, refuses to add any tx that doesn't have at least a meaningful fee (say .0001), that's BENEFICIAL to pool members.

what da' crap are you on.. the idea of blocks is to confirm transactions.. if people are ignoring transactions then they are ignoring the whole point in mining.. and only doing it for greed.. meaning unethical..

no transaction should be ignored. otherwise the benefits of bitcoin disintegrates..

hmm let me guess you dont care about bitcoin. you just want to cash out your mining reward back to fiat and store it in a bank account. and you dont give a fuck about the benefits bitcoin can bring.

lets get to your point though

if i had 1000 transactions, they are just 1000 transactions whether they have a fee or dont have a fee, they are just transaction data.
the fee does not change the chances of a orphan.
pool owners want to reduce the 1% risk of an orphan by only allowing in 100 transactions of data.. again whether with fee's or not, does not affect orphan chance. but what does affect orphan chance is data amount.

pools are getting so greedy by not just accepting transactions. that they are forcing people to add fee's. not because it reduces the risk of orphans. but because it gives them VIP status to be allowed into a small and limited block.

which goes totally against what bitcoin was all about. transaction freedoms.

we are trying to move away from the banking system that requires high transaction costs just to do business EG Mastercard Black


Yeah, that might've been the pipe dream, but the reality is people paid millions for asic hardware to be greedy and make a profit.
67  Bitcoin / Bitcoin Discussion / Re: New attack on the bitcoin network. on: April 07, 2014, 03:19:39 AM
I don't see anything wrong with the blocks.
Even if we have 1 or 2 selfish miners, there is not much problem as the unconfirmed tx will be picked up by the next block or so.
After all, we are still far from the 1MB block limit.

Okay, so what happens if every miner turns selfish?  Do you expect most of them to always be good at heart?

if mining pools put in silly rules such as what eligius have done in the past.. then if it causes too much trouble, people will not use those mining pools and instead make new pools that have better code to be more honest.

after all if a pool is going to mess with peoples transactions so they cant even cash out their bitcoin into an exchange. then they wont use the pool.

mining pool owners love shooting themselves in the foot due to greed.. im glad the number of feet they have to shoot is limited before their left crawling on their hands and knees.

if anyone finds out which pools are messing with blocks/transactions. post the pools IP so everyone can remove the ip from their supernodes lists, allowing for other pools that are more ethical to receive transactions. then the miners will move onto the more ethical pools, because they will learn they wont be able to withdraw any unethical block rewards. wasting their mining hashpower on an unethical pool that wont pay out

The fuck are you on?

Every tx you add to a block slightly increases the odds of it being orphaned. So if a pool say, refuses to add any tx that doesn't have at least a meaningful fee (say .0001), that's BENEFICIAL to pool members.
68  Bitcoin / Bitcoin Discussion / Re: Bitcoin Virus? on: April 06, 2014, 11:18:47 PM
There was a pastebin fairly recently that suggested exploiting the fact you can attach short amounts of data to the blockchain by spamming the network with transactions that contain signatures for random viruses. Thus being flagged by tons of AV software, and potentially causing a loss of coins.
Although it can't actually cause loss of coins. It can only cause problems for local clients, and I think the pastebin over-states the effect.

My Win8.1 PC reported a virus detected in the Bitcoin database today. I just marked it as "Allowed" and then told it to ignore the Bitcoin directory there-after. If I'd picked the default action of "Quarantine" instead, I imagine I'd have been able to unquarantine it later, or else just download the block again. As it is, not only am I fine, but I can re-broadcast the block to anyone else who needs it. As long as one person has a copy, we're fine. The crypto means the block can't be forged. No coins are going to be lost.

It's mostly just to fuck with people who are too stupid to configure their antivirus properly.
69  Bitcoin / Bitcoin Discussion / Re: Bitcoin Virus? on: April 06, 2014, 07:14:20 PM
Is this info legit?

If so, sounds like fun.

I quit running antivirus years ago because of issues like exactly this. It causes more problems then it solves.

I run my web browsers either sandboxed or in a virtual machine. Run any suspicious software (like keygens) sandboxed or in a VM, and only download software that I'm relatively sure is safe.

I haven't tested it, because I don't run antivirus software (On Linux at the moment, usually running some flavor of Unix), and I don't feel like spinning up a VM.

Lots of AntiVirus's basically scan for known byte-patterns of malware, at least when doing a basic static scan. Smarter ones might check where the "signature" resides to try to determine if its actually malicious, others will flag it regardless of the signature position.

So, at least theoretically, it should work against a few AV's.

Hmm. how are messages attached to a transaction in the blockchain? And how are they stored?

And where would I get a list of known virus signatures?

The good news is that you can't really create a virus via the blockchain. Messages are limited in size (20 bytes? I think), and there's really no room to create an exploit since the format is so well-defined.

71  Bitcoin / Bitcoin Discussion / Re: Possibility of a 51 percent attack during a US blackout? on: April 06, 2014, 05:07:45 PM
If someone wanted to do a 51% attack, they'd be better off doing a ddos attack against the major miners then hoping for a blackout, LOL.
72  Bitcoin / Bitcoin Discussion / Re: What happens when bitcoin mining is obsolete (who will verify the transactions?) on: April 06, 2014, 04:49:38 PM
I wouldn't worry about that.

It's going to be decades before the block reward is close to 0.

Bitcoin will collapse before then.
73  Bitcoin / Bitcoin Discussion / Re: Soon to be college grad in need of advice- what's the deal with Bitcoin? on: April 06, 2014, 05:51:26 AM
  You can buy plane tickets with bitcoin- good prices on destinia.com

  Bitcoin is not an investment- it is a way to get out of the utter corruption of the current financial swamp. Seriously, just using dollars might go down in history as criminal- just because everyne is doing it doesn't make it right. It is our moral responsibility to avoid supportig the power of elite bankers who are using the labor of the oppressed for extravagant and luxurious life styles.

    You have to patronize bitcoin businesses and help the network grow, and the value of bitcoin will grow with it. You can put off paying your loans- every country in the world has done it.

http://www.amazon.com/This-Time-Different-Centuries-Financial/dp/0691152640



Lol, you realize all currencies, including bitcoin is a ponzi scheme right?

Guess where the money came from to pay off early bitcoin investors? You guessed it, new investors.

At least with the dollar, you know what it's going to be worth. It has a steady decline of a few % / year in value (due to inflation). Yes, if you hold a dollar for 50 years, it'll lose almost all it's value, but you KNOW that in advance, it's NOT a surprise. And in 5 years, it'll have 80 - 90% of the purchasing power it does today.

With bitcoin, who the fuck knows what it's going to be worth a year from now. Could be 1000, could be 100.
74  Bitcoin / Bitcoin Discussion / Re: Transaction confirmation time down on: April 05, 2014, 10:50:35 PM
Average confirmation time of ~10 minutes is still quite significant. Won't cause any problem for the online shoppers. But people who want to use BTC for retail shopping won't be able to do it.

Retail transactions are routinely performed at 0 confirmations, because transaction propagation alone validates any given transaction better than any other payment method in existence already. 10 minute blocks being a hindrance to retail application is the biggest myth that absolutely refuses to die.

Except as a business owner I'm not giving you ANYTHING till I see 3 confirmations.


There is really no need for that. Once you see the transaction go through, even without confirmations, you are safe.
The transaction will end up going through...there is no way for the purchaser to reverse it once you see it show up.

OK, I thought that having 51% of the hashing power allows you to do just that and more....

Exactly! Since nobody controls or will control 51% of the hashing power, there is no fear for a business owner.

You could double spend the transaction.

If you control 10% of the hash power, you can replace the Tx in your mempool with one that overrides the existing one. It'll have a 10% chance of working.


Who controls even 10% of the hashpower??

And why would you risk losing your 25 bitcoin block reward just to have a small chance of double-spending some satoshi at your local starbucks, lol.

Any amount of money that would be comparable to the current block reward (25 btc) would wait for one confirmation at least.

Double spending <<1 BTC isn't worth the pain it would take to have the small chance of succeeding.

Do you remember when grocery stores used to cash checks for you so you could do your shopping? People defrauded them all the time and they'd put up your picture and never accept checks from you again. It was part of the cost of doing business but brought in a lot of customers because it was convenient.

 

Are you serious?

The majority of the hash power is concentrated in pools that control > 10% of the hash power.

There's also no risk losing your 25 btc block reward. All you're doing is replacing a tx in the mempool with a different tx.

And if this were done, it wouldn't be done to scam starbux outta a $3 coffee. Someone could buy thousands of dollars worth of stuff at best buy and do it.
75  Bitcoin / Bitcoin Discussion / Re: Custom Bitcoin address ? on: April 05, 2014, 07:30:47 PM
what's the chances someone could hack those custom addresses (or any other addreses for that matter)
Hack how? Ask a more specific question.


by hack, I meant how likely is someone to find the correct private key given the public key with that generator

Zero
76  Bitcoin / Bitcoin Discussion / Re: Custom Bitcoin address ? on: April 05, 2014, 07:03:03 PM
well maybe no one can spend the coins in those addresses.

but take a look here

https://blockchain.info/fr/tags

lots of custom addresses

just a few from that page

and more!

They have the money to spend those and they all have a connection to what they are used for

You can generate short custom addresses. This one is mine:

https://blockchain.info/address/1Niggerw15VezU6rA7jRBuJt9ceg9VL1jh

Took 15 minutes of GPU time to generate.

lol, nice

but the question is still how?

you let your gpu run on a script for 15 minute and you found that one ?

it's a program called oclvanitygen

It's possible to "mine" private keys to look for ones with a desired string in them, but for more than 7 or so specific characters that gets computationally infeasible, so if you see ones like that then yes they are most likely invented and coins sent to them will be lost.

I can realistically do 8 characters (case sensitive) or 11 characters (not case sensitive), but those will take quite some time to do (a month)

7 characters (case sensitive) would take under 1 day.

78  Bitcoin / Bitcoin Discussion / Re: If there's a huge drop in hash power.. on: April 05, 2014, 06:58:00 PM
Since the introduction in ASICs, there's never been a drop big enough where energy cost of mining > value of btc produced.
Ahh but it has happened under the video card era, and there was no drop.  There's no reason to believe ASIC operators would be any different.

You can bet those datacenters spending thousands of dollars in electricity a day will turn off their ASICs if it turns unprofitable.
Only if those data centers are relying on immediate BTC sale to pay their day to day bills. If they're in it for long positions, the daily exchange rate means diddly squat.  

Yes, if the exchange rate drops precipitously and stays low for a long period, some miners will drop off and instead put their money into direct purchase.  Will it be 95%? No.

Also remember that there's more to mining than just acquiring BTC.  If there were not, there would be no ASIC sales. There's not a single machine you can order today that will make more than it costs in BTC over its lifetime. Yet they still continue to sell.



You think someone who has millions to invest in an ASIC datacenter is stupid?

If the cost of mining a coin = $10 in electricity, and the current price of bitcoin is $5, someone who's in it for the long position (and has half a brain) will turn off their ASICs, and spend the money they would've spent on the power bill buying the bitcoin on the market.

Pretty simple math here.
79  Bitcoin / Bitcoin Discussion / Re: Custom Bitcoin address ? on: April 05, 2014, 06:52:14 PM
I saw that a few times on blockchain.info and now with the kaperlescoin...

how is it possible to have these "custom" addresses on the bitcoin network ?

3KARPE1ESwHERE1SoUrMoNEYxxxx8dXeC5



It's easy to generate a public key.

Nobody has the private to key to that though, so any coins sent to that address are not spendable.

80  Bitcoin / Bitcoin Discussion / Re: If there's a huge drop in hash power.. on: April 05, 2014, 07:28:31 AM
Btw, someone said that if 95% of the network hash power left, the remaining 5% would see a 20X increase in mining reward. That's simply NOT true.

It WOULD be true AFTER the difficulty resets to a lower level. But up until that point it would take you just as much electricity to generate 1 BTC as it did prior to the network collapsing.
