Maybe bad random generator in QT strikes again?
142  Bitcoin / Development & Technical Discussion / Re: How hard is it to make a bitcoin clone (or nearly a clone) on: January 23, 2014, 09:22:01 PM
Once you found and understood the critical sections it would be very easy. For instance there is a "network" id that for Bitcoin is 0, simply changing that to something else would do the trick.

I think even changing the hash function would be somewhat simple as a crypto library is likely used - just call another function.

This is why I think there are so many worthless alts, they call a different hash function in a library someone else made and call it a miracle.
143  Bitcoin / Bitcoin Discussion / Re: 2 problems with Bitcoin on: January 16, 2014, 07:41:43 PM
1. Carrington type event
2. no intrinsic value

comments?


1. I think in the event of a solar flare large enough to take out the whole internet, we will have bigger things to worry about than bitcoin being unavailable for a little bit. Credit card processing, telephones, money transmitting, the stock market, cell phones, television, and radio would all be unavailable.

2. So? You need to provide a better explanation as to why this is a problem.
Actually the Carrington event itself only affected parts of the world, Bitcoin being distributed would be the last network to collapse.

By the time internet connectivity returned so would Bitcoin from other parts of the world.

It is also very likely that the normal banking system would NOT make such a swift recovery.

Twice in Almost Human, maybe more. Great show btw.
145  Bitcoin / Bitcoin Discussion / Re: How much bigger can Bitcoin get? on: January 12, 2014, 11:10:19 AM
Unless scaling issues and pool issues are solved not much bigger.

Good news is its possible, bad is we don't seem to have willing developers.
146  Bitcoin / Bitcoin Discussion / Re: Western Union DEAD in the Water !!! on: January 12, 2014, 11:06:18 AM
WU is often used by over seas workers with little education. Bitcoin may be better, but WU is still more user friendly since you go there and just do what a person tells you to do.

My workplace's customer (I'm a programmer) recently asked me to disable all validation in one of our programs - which could cost lives I guess - but our customer is too stupid to fill out correctly and can't be bothered.
147  Economy / Economics / Re: Why are economists so afraid of Bitcoin? on: January 10, 2014, 10:22:34 PM
Bitcoin is a real world experiment. They know deep down that their theories are wrong and are afraid bitcoin will prove it...
+1

It will disprove the one economist theory that everyone knows.
148  Economy / Economics / Re: Economic Idiocy on: January 10, 2014, 10:12:57 PM
I find it more sad that economists think they know anything when their theories are so useless and almost always wrong.

Modern economics are more like sports commentary or religion than a science.
Would you like to provide some reasoning? Your conclusory statements ain't true jest 'cuz yew sez so.

Their "theories" explain human behavior and the choices that humans make. Well, at least the honest economists do.
One good example: "2% inflation a year is good for the economy" every mainstream economist will spout this but I have NEVER heard them cite a single study, they just pulled it out of their ass.

- Why 2% and not 0.5%, 2.5%, 3% or 10%?
- Typical justfications are "deflation is BAAD" or "keeps people employed", which may or may not be true, but you can't SAY stuff like that without some hard goddamn evidence.

Another good example is often they will cite a SINGLE data point and use it to justify insanely wide generalizations - examples that they often get wrong too:

- The great depression was caused by a bunch of bad investments that collapsed, this caused people to pull out their money and the value of money rose temporarily. Economists will often blame the deflation rather than the actual down to earth cause of bad investments.
This is by the way their ONLY example of why deflation is bad - and its wrong.

Finally science is actual a VERY simple protocol and economists do simply NOT follow it:

- Positivism is the core methodology behind science, without it you are simply not doing science.
- It states that a theory should be logically self consistent (ie if 2+2 equals 4 on mondays it should do so aswell on tuesdays, unless the theory specifies otherwise of course) AND a theory must be disprovable.
- So: 1. Make a theory. 2. Make a prediction (it can be statistical). 3. Test if true. I have NEVER heard of an economist theory developed or tested like this and hence per DEFINITION economics is NOT a science.
- You can see this often in the excuses economists make up on the fly as they are wrong again and again - it sounds a lot like religious people justifying their beliefs with weird exceptions and phrases.

Bonus stuff:
- Complete failure to include the physical world in their calculations, acording to economic theory you would probably have a swell economy if you had 2% inflation a year even if all energy sources in the world suddenly disappeared or "demand" would magically materialize the disappeared/used up energy.

- Complete amateurs often make better predictions, I remember Resilience.org documented a significant correlation between energy (oil) consumption and economic activity - wheras economic theory would make you believe energy prices should crash at increased supply.
They also showed that if economists idea of infinite growth held true, the planet surface would BOIL in 1-200 years from simply the activity going on (not global warming).

- I recently heard an economist say that economists assume 100% employment OVER TIME... and I could not believe how stupid it was.. its been millenia and hello not everyone is employed! There are COSTS to employing people and the retarded, handicapped and unwilling will NEVER be employed.

- I could literally just keep going.
149  Bitcoin / Bitcoin Discussion / AES in javascript only anyone? on: January 09, 2014, 06:03:55 PM
Does anyone know of something like Bitaddress.org, but for AES?

I want to be able to download it as a HTML file and put it on my offline "Bitcoin banking computer".

It should encode, decode and take input and a key (so I can encode private keys).


I am immensely inspired by the fact that SO FAR DPR has been in FBI custody for months and had had all his possessions confiscated and STILL they don't have his money.
That is so fucking powerful.

Im already safe against hacking and theft (I think) but if I could be safe from the police too...

EDIT: I found this - http://lazarsoft.info/crypter.html
And it seems to work as I want, but I can't seem to get any of the online AES tools to actually work together, they all give different results from the same key/input.
150  Bitcoin / Bitcoin Discussion / Re: DPR's Bitcoin Stash future sell off by the gov't panic ensues .. on: January 09, 2014, 12:07:04 AM
Proudhon got banned? I was wondering what all the panic posts were about. You pissed Proudhon?
No just quiet for a while.. I thought.. from his activity history it seems I just missed it..  Roll Eyes
151  Bitcoin / Bitcoin Discussion / Re: Bitcoin's 10000 TH network is extremely vulnerable on: January 09, 2014, 12:04:14 AM
This has always been an issue and was much cheaper in the past.

I am sure it has been discussed before.

I suppose it would be possible to implement some sort of trust system for nodes. Devs and pool operators would need to work together.
I suggested a trust filter before.

Possible trust filter algorithm:
1. A full node only accepts a block if ONE of the PAST 50-100 blocks were on its "trusted miner" list.
2. Miners could sign their blocks in different ways without requiring total compliance or a protocol change of any kind.

Result:
If one bad actor 51% attacks the network and prevents all transactions, nodes with trust filter enabled will STILL require some competitors blocks to be allowed leading to the 51% denial of service attack to FAIL.

Similarily rewriting block history far back with your own blocks only would fail.

Aren't there like many ATMs now?

I saw a lamasu at the last nordic bitcoin conference.
153  Bitcoin / Bitcoin Discussion / Re: DPR's Bitcoin Stash future sell off by the gov't panic ensues .. on: January 08, 2014, 12:48:06 AM

...So that they can get less for the assets than they would have otherwise?  In any event, this isn't even the worst news of the day, since sources have disclosed that the Chinese and US governments have entered an agreement whereby they work to filter out and block all cryptocurrency network traffic.  Look it up.  It's been confirmed via sources.
Proudhon returns!

Well Im happy for nice buying prices, keep the bans flowing.
154  Economy / Speculation / Re: Is BTC still in a 1150 USD buble...? on: December 29, 2013, 11:56:02 PM
Are you making analysis without so much as checking the price on an exchange? Fascinating...
155  Economy / Economics / Re: Economic Idiocy on: December 25, 2013, 10:30:48 AM
I find it more sad that economists think they know anything when their theories are so useless and almost always wrong.

Modern economics are more like sports commentary or religion than a science.

I'll give you points for mentioning the Austrian school of economics though.
156  Economy / Economics / Re: Technological unemployment is (almost) here on: December 18, 2013, 01:55:04 AM
In my mind the core function of humans is to be intelligent.

To survive AI we must invest in biotech and bioengineering to improve ourselves. DNA computing is supposed to be a possible future in computing and we have it in our bodies already aswell as a brain that has not reached its full potential yet.

Robots may be coming for the cashiers job, but how far are robots from Einstein level humans? More CPU does not necessarily mean smarter, the algorithms used matter and ours have 4 billion years of evolution behind them.
157  Bitcoin / Development & Technical Discussion / Re: Fees are too low by a factor of 32 - Marginal Transaction Costs on: December 12, 2013, 07:07:55 AM
Well we probably have a factor of 32 too many miners too so that will work out nicely when the subsidy ends.
158  Alternate cryptocurrencies / Altcoin Discussion / Does mastercoin rely on a single address? on: December 08, 2013, 10:49:55 AM
So the way I understand it so far MasterCoin was created by sending BTC to a certain address:
https://blockchain.info/address/1EXoDusjGwvnjZUyKkxZ4UHEf77z6A5S4P

Using Mastercoin also involves sending (a small amount of) BTC to this address.

A KEY feature seems to be that in this way the core developers are well funded and can expand the MasterCoin software ecosystem.


... sooo if a hacker gets this ONE exodus address won't mastercoins be worthless in sort time?
159  Bitcoin / Development & Technical Discussion / Re: What safeguards can I use when attempting 0 confirmation transactions? on: December 08, 2013, 10:20:36 AM
Make sure you have a well-connected node.

After you first see a transaction, wait X seconds and look for double spend attacks.

If no double spend attacks have occurred yet, then you can assume the odds the transaction you want will be included in a block instead of a conflicting transaction is at least Y%.

Don't ask me how to calculate X and Y, but if you can accurately estimate Y then you can just increase your price by n*(1-Y) to cover expected losses from double spends. Where n is the fraction of customers who try to scam you.

To add one important thing to this: Require a reasonable fee from your customers, a zero fee payment versus a high fee double spend is not the best scenario.
160  Economy / Economics / Re: Are "lost" BTC already priced in? on: December 04, 2013, 05:12:49 AM
I see comments frequently to the effect of "There are many missing coins, the real price should be higher"

Aren't missing coins, by virtue of not circulating or being exchanged, already priced in?
Well first of all, if they are NOT circulating that makes the price HIGHER. If they WERE circulating the price would be LOWER. (due to increased BTC supply)

Are they priced in? Yes and no. Yes because "everyone knows" the risks involved and can invest accordingly and no because for instance the maybe ~1-2 milion bitcoins Satoshi has may never move or may be dumped tomorrow and enter more active circulation.

All you can say is that supply and demand has priced in whatever is in circulation at the present moment.
