2761  Bitcoin / Bitcoin Discussion / Re: Changetip and why it is the killer app that BTC needed on: November 19, 2014, 08:07:06 PM
What about putting changetip links on our own web site that are for someone else?  e.g. Suppose you wanted to ask for donations for @MakeAWish (via twitter). 

Precompose a tweet, then you can tell visitors, "Instead of buying me a present for the holidays this year, just make a donation to <whatever the charity is> by clicking on this link."  You could always offer to match some of the donations to encourage people to sign up!

That way, if you want to encourage use but don't want to ask for ask for yourself, you still can.  Something like:

Donate to Make A Wish via Twitter, ChangeTip and Bitcoin

Which is just this link:
http://twitter.com/home?status=Hey%20%40MakeAWish%2C%20here%20is%20%241%20for%20your%20good%20work%20%40ChangeTip%20Thanks

with a URL anchor attached.

Maybe just have the miners delete all addresses with less than 1 bitcoin as dust.

lol.  

Some of the ideas that get floated that will never happen are just amazing.  "Someone else please destroy your coins so mine will be worth more."  No offense steelhouse, but if you get this to fly with anyone, I'd be amazed.  ;-)

I am not asking anyone that wants to keep their bitcoin to destroy them.  I am asking for donations for deletion.  I am asking for the Walmarts of bitcoin to delete bitcoin as self promotion and philanthropy.  The sales tax averages about 10%, if that money was funneled into deletion instead bitcoin would be the world reserve currency!

I get it.  I just doubt you'll have many people take you up on it!  :-)

If you can get someone (or many people) do destroy 1 million BTC, more power to you!

FAC = FACILITY

"IS BITCOIN A FACILITY?"

I still don't know what that is supposed to mean.

I think it is supposed to be "Is Bitcoin a Fad?"  -- looking at the original link now that it is up from here it says "Fad" not "FAC".

2767  Bitcoin / Development & Technical Discussion / Re: Bitcoin ATM - Legal Silk Road on: November 19, 2014, 10:59:45 AM
Obviously I know that silk road was very illegal and hidden on the dark web. But how hard is it to create an encrypted website that no one can access aside from admin? an encrypted craigslist essentially i guess...



Also, who should I look for to develop a a computer powered and programmed device...like the lammassu knows how to perform the exchange capabilities. What kind of person would be able to program that...electrical engineer, computer engineer...might not be as easy as a tablet. Might just be a small computer board situation...so would that be a computer programmer?


Thanks

Probably off-topic for this section...

It is extremely difficult to do it properly.  There are numerous attacks on TOR - one study de-anonymized 81% of users (1) for example, there are many more examples such as ddos.  Some of these are not problems with TOR, just problems that TOR does not protect against (e.g. a state sponsor who controls many routers on all sides of TOR.  Then you have to worry about other security holes in the software (e.g. php, mysql, apache, your own software etc).  Then you have to worry about misconfiguration of your software.  Then you have to worry about whomever you hire to do the work for you - are they going to blackmail you later, are they working for a government etc.  Then you have to worry about the legal jurisdiction you are working from and the consequences of that.  

It is easy to give a glib answer and say you can do it easily, but that is untrue.  It is very, very, very hard to do it correctly, and even if you think you have covered everything it only takes one screw-up for as long as you run the web site and you will be done.  There have been a large number of discussions as to what SR, SR2 etc all did to get caught, some believe NSA and then they used parallel construction ("legal perjury by the government"), others just believe mistakes.  Probably some combination of all of the above for various web sites.

So, you'd want someone (a computer programmer, engineer or the like) who has done this before and is knowledgable.  Even then someone will probably make a mistake or a well-funded government will use their resources to figure out who is running the site.  Right now unless you are working for Putin in Russia (Castro in Cuba, any intelligence agency anywhere, as an example) where you have protection in your own jurisdiction it would be extremely unwise to trust the anonymity tools currently available.

What is a FAC?

Time will tell if he is correct, but people don't need to know how to build an automobile engine to use an auto so this person seems to have not thought out things very well.  Most people don't know how lift works on an airplane, but they still fly.
2769  Bitcoin / Development & Technical Discussion / Re: Is it really necessary to keep bitcoind on separate server? on: November 19, 2014, 10:37:51 AM
i dont see a problem with having them on the same machine as long as that server does not control any funds.

any bitcoin server which can be used to send money should be on another network and on a machine which you control physically to avoid attacks from your hoster.

No need, the machine can be encrypted, or even just the wallet encrypted and unlocked when it has to send out funds. And only use https calls to get data so that the host can't find clues in the traffic.

This is bad advice (except the https part).

notme has given you good advice if you want your funds to be safer. I won't repeat what he said, but his advice is sound.  (You should also be concerned about using a VPN, bitcoins have been reportedly stolen from them even with good security, by ISP employees.)

2771  Bitcoin / Bitcoin Discussion / Re: CATO Evaluation of Bitcoin Eventual Collapse of protocol on: November 18, 2014, 05:51:38 PM
This.  Also, in the not too distant future we'll hit the same process as CPUs, memory etc for miners.  E.g. 14 nm, 7 nm, 5nm.  Once mining rigs hit the same process that CPUs and other semiconductors are using for that generation hash rate increases will level off and growth will be due to the number of chips sold and much slower increases in hash rates due to process improvements.  E.g. the Avalon was a 110nm process for their chips, the AntMiner S3 is 28nm process and other chips are using smaller processes (all iirc although I think they are accurate or very close).  The performance increases between GPU and 110nm was huge.  The performance increases between 110n and 28nm (for example) are large too.  

However, going from 28nm to 14nm (what Intel is using in many of their chips now) is good, but not the same order of magnitude as 110nm to 28nm.  Once you see new mining rigs all running on the current process at a high clock rate, then I believe that you will end up with more opportunities for "hobby miners" since they will be able to project an ROI much easier and it will be much more likely that they will be able to have a ROI.  People will be much more inclined to purchase a miner if they know it won't be replaced by something 100 times better in 3 months.

This will be a somewhat more stable situation in terms of hash rate increases and miners coming to market.  It will be closer to how CPU mining was in 2010 and GPU mining was in, 2011-2012 (even the first third of 2013) where you could buy a few video cards and have a pretty good idea that they would return X BTC/week (decreasing slightly each week due to added GPUs on the network) for a year or two until a new video card came out and that might cause a slight increase in the difficulty increases.  And even then you might mine some fewer BTC/week but not 1/1000th of the number in that period like the difference between January 2013 and November 2014.

It is difficult to model and so it is not surprising that they may not be catching all the nuances there.  I certainly wouldn't be confident in being able to predict it all going forward.  Particularly with so many variables - regulations, halving in ~18 months, improvements (e.g. sidechains etc), new uses.


...
Yup. Additionally, large miners are likely to, eventually, vertically integrate other services. There are some potential negatives (as well as positives) to that, but it also probably means that there are a number of workable business models for a number of large fairly-efficient miners, as opposed to an endgame where strictly the least-cost producer gobbles all hashpower.

Regardless of all that, the same arguments that are thrown around about mining could be thrown around about data-centers in general (OMG! there will only be a single least-cost/massive-scale producer that will run everything!), or pretty much *any* industry for that matter; this is really just a (mostly) extrapolated-short-sight criticism of capitalism in general, not specifically bitcoin mining. Few industries actually coalesce to pure monopoly in practice.

Anyway, the natural incentives of bitcoin mining make it less likely than other domains.

Were I him I would serve my sentence, 600.000 BTC is a good paycheck for ~20 years. + You can read and stuff in prison.
I didn't know that there was 600 btc not accounted for.
Any link to the address with the 600 btc?


Are you talking about 600 btc or 600 K btc, as above mentioned? Typo ? It is quite a difference

Yeah, 600 bitcoins isn't much when there were 50k+++ elsewhere.

600k, I never heard that number except as a total that flowed through SR.

2774  Economy / Service Discussion / Re: Big exchanges doing tha pumpdump. All they want on: November 17, 2014, 11:08:05 PM

I disagree.  Exchanges have higher volumes than local.
Arbitrage opportunities keeps price manipulation in line.



lol so you think btc-e's database platform which does bot trading and fractional reserve trades with a volume of on average less than 20k coin movements a day, which are normally just 2000 coins at most going back and forth upto 10 times a day...

you really think that people should base bitcoin true value on this type of day trading..??

or would you prefer to trust a platform where each trade is a result of a real bitcoin vs a real bank account transfer.
personally i just values of localbitcoin and OTC trades averages and dont even look at php/mysql database exchanges.

It really doesn't matter what they do (as long as no one gets "goxed") because there are several exchanges.
Remember the rule of one price.

http://www.investopedia.com/terms/l/law-one-price.asp

It definitely does matter what they do IF, as franky was discussing, people are relying on it for price information.
2775  Bitcoin / Bitcoin Technical Support / Re: "Transaction has a none standard input" Please Help on: November 17, 2014, 11:06:19 PM
I can certainly contact the person who sent the coins and tell them that.

Can I tell them to do anything that will fix the issue? Will the coins eventually confirm into my wallet?

I know this has never happened to either one of us.

Again, many thanks for the advice

This was a transaction sent to me, but I can contact that person.

The same person sent me another transaction and it was confirmed right away.

Fixed.
Look for this malled tx https://blockchain.info/tx/8fb6dea75df3a1be74950164a99acb1bede6cfadf3979cc89c351b239773c568
It should be confirmed soon

This looks like it has at least one confirmation now.

This seems like the wrong section depending on what you are asking.  I don't understand the question though.

If you are asking how you point a domain name at your server, you configure the name servers so that www.domain.com points to your IP address.
2777  Bitcoin / Development & Technical Discussion / Re: How the difficulty is adjusted in this situation ? on: November 16, 2014, 06:17:49 PM
As I understand, the more number of zeroes are required in a block hash, the more it is difficult to find. Now suppose, the target is to find a hash with more than 8 zeroes in the left, but the found hash hash 20 zeroes in left. Does it mean that the next hash has to have more than 20 zeroes in left ? How network will adjust this sudden difficulty spike ?

Please let me know if I'm having any conceptual mistake here...

no
any better hash works. difficutly only adjusts after 2 weeks in blocktime and only takes the time-diff between blocks into account: not the value of the found hash itself

I know the standard definition of difficulty. That was not my Q.

Zeroes required in a hash to be accepted as valid is set by the network. And finding hashes with less number of zeroes by changing nonce is called hashing. That is the difficult thing for a miner. More the zeroes, more difficult it is. Is not it ? This is what I have meant by difficulty here. NOT the standard definition.

His answer to your question was correct.  The 20 zeroes does not change the difficulty at all.  Anything less than 8 zeroes is acceptable in your example, and that continues until the next difficulty adjustment.

2778  Bitcoin / Press / Re: [2014-11-08] Forbes: How Did The FBI Break Tor? on: November 14, 2014, 08:09:42 PM
CASE IN POINT: "81% of Tor users can be de-anonymised by analysing router information, research indicates"

Research undertaken between 2008 and 2014 suggests that more than 81% of Tor clients can be ‘de-anonymised’ – their originating IP addresses revealed – by exploiting the ‘Netflow’ technology that Cisco has built into its router protocols, and similar traffic analysis software running by default in the hardware of other manufacturers.

http://thestack.com/chakravarty-tor-traffic-analysis-141114







I don't think anything is safe now and I certainly don't trust tor. It's really saddening what our governments are doing enroaching on our freedom just because they ironically claim they want to protect it.
You dont come with any agrumentes , and you are a newbie sorry Smiley
Tor is Save ,,, https://www.youtube.com/watch?v=oL1UyLRo1Ds knows
and I rather trust him then some newbie Smiley



Parts of Tor may be safe, but using it and expecting to run a hidden service or to use it to access a web site while remaining hidden from the DEA, FBI, CIA, NSA, etc and non-US agencies is just plain stupid. Between MITM attacks, three letter agencies running more than half the exit nodes, limiting internal hops, ddos attacks, non distributed directories etc, the security of Tor is insufficient to be considered safe against state sponsored attacks.

This may not be clear immediately when the government supports officially sanctioned perjury (parallel construction) but anyone who uses Tor for something like Silk Road 3, 4 etc is not using their intelligence.  In short, Tor should not be considered safe for anything but the most innocuous of uses. This is not a criticism, but the facts.

One hopes that Tor upgrades address the attack vectors in the future, but currently there are many unknowns. Tor is a great concept, but is not perfect.




2779  Economy / Speculation / Re: News you may have missed - IMPORTANT on: November 14, 2014, 05:29:47 PM
Not much. By majority of population, bitcoin is perceived to be even less secure than banks, people are certainly not gonna put their savings in it.

Thats like saying account holders in cyprus would still feel comfortable keeping their fiat in banks.

How do you justify your statement for any serious financial player?

And how much did Cypriot account holders lost exactly?
Let me tell you, those with more than $150 000 at the account have lost 40%, and those with less than $150 000 lost nothing.
Meanwhile, those who invested in bitcoin last november, lost 60%. Those who invested in bitcoin 20 minutes ago lost 10%

Point is... Do you place trust in a eco-system that can take your funds as and when needed or do you place trust in funds you can control yourself?

I think you are missing the bigger picture here... For sure many need educating but for those well versed, the writing is on the wall.

Bottom line is: less faith in traditional banking system.

What does this mean for bitcoin medium-longterm?

Education of general population is short term which is not what this thread is referring to.

Deadcoin,  the European commission took over 720k€ from this guy in Cyprus, leaving just over 127k€ with a shitload of restrictions, I wonder if he ever recouiped anything of his losses. See: https://bitcointalk.org/index.php?topic=160292.0 

edit to add: Asked if, like in other bank closures, it could take six to seven years before depositors get back there money, he said: “maybe yes. And the amount [returned], could be 20%. Certainly, for depositors above 100,000 euros it could be a very significant blow.” source: http://greece.greekreporter.com/2013/03/27/cyprus-finance-minister-uninsured-laiki-depositors-could-face-80-haircut/

Yeah. He left there and moved to the Caribbean, taking his jobs and money with him. He wasn't alone leaving fewer people to screw next time they need cash.

You should use Desktop Wallets.It is safer than online wallets. Because it can store your Bitcoins on your computer’s hard drive instead of on the internet.

Bad advice.  Look up cold storage here, if you have any significant number of coins, storing them on your computer or on the internet (e.g. "the cloud") is a bad idea.
