Just to make sure there is no confusion, I have no funds on deposit @ Dank Bank.  
I was just providing some clarification on terminology (i.e. a debtor shouldn't use the term donation just as a charity shouldn't use the term deposit).

Looks like this is being done through thefundersclub.com.

So you have to be fairly wealthy to invest. Lame lame lame. Sad

The good news is US securities laws will change in "January 2013 ? don't quote me on the date " and will allow crowd funding by investors who are not "accredited" (i.e. us normal shlubs).  Probably the only decent piece of legislation Obama has passed.

njw the mods are serious about the "Linking to illegal sites is forbidden. If you bypass this censorship, you will be banned" warning.  It is one of the very few things which will get you banned.  Even scamming (normally) won't get you banned.   That entire domain and similar sites are off limits.

An expensive but comprehensive solution would be to operate a remailer service (possibly funded by bitcoins) from a country which still protects privacy.  The postal mail equivalent of a VPN proxy.
8465  Bitcoin / Development & Technical Discussion / Re: What are the chances of an address collision? and what happens when it does? on: August 29, 2012, 09:07:17 PM
Not to hijack the thread, cuz i'm sure other people will read and be curious abut his too: But can some one quickly explain why its also very unlikely to accidentally type a valid Bitcoin address.  They are 33 (32 unique) case-sensitive alpha-numeric digits (Base 58).  Only a subset of all possible combinations are valid addresses.  What is the method and explanation for this?

The address contains a 32 bit checksum.  So a typo will most likely result in a bad checksum.  Node compute the checksum to ensure the address is valid so "most" typos will simply produce an invalid address which will be rejected by your client, other nodes, and miners.  In theory you could create a sequence of typos that also produces a valid but incorrect address but the odds are roughly 1 in 4 billion.

Can some one also explain how if a public address is a sha hash of a public key, how can an address be signed by the owner of the privkey, if the public address can't be reversed into the full public key  (the key pairs are 256 bit ECDSA right?  Should be loner than 32 characters).

Technically the address isn't signed.  A message is signed by the private key.  The signature can be verified by the public key.  The signature contains the public key.  The address can be verified by recreating it from the public key.

He is, I'm just very surprised he hasn't said that it's awesome yet.

I wonder what is holding him back from fully endorsing it? any thoughts?


He likes wrecking Ferraris and slurping caviar off the bottoms of bikini-clad girls. There's not a lot of BTC based offers for this.

Sounds like an untapped market.
8467  Bitcoin / Development & Technical Discussion / Re: What are the chances of an address collision? and what happens when it does? on: August 29, 2012, 06:15:07 PM
Yes but that is just the formatting.  The address is still a 160 bit hash of the public key (plus some version info & checksums) expressed as a modified Base58 string.
8468  Bitcoin / Development & Technical Discussion / Re: What are the chances of an address collision? and what happens when it does? on: August 29, 2012, 05:44:45 PM
So finding a collision on your first try is roughly equivalent to being hit by lightning 16,540,000,000,000,000,000,000,000 times per second for an entire year or winning the lottery 830,000,000,000,000,000,000,000,000,000 times.

8469  Bitcoin / Development & Technical Discussion / Re: What are the chances of an address collision? and what happens when it does? on: August 29, 2012, 05:35:42 PM
The odds in colliding with a specific address is 1 in 2^160.

If there are a billion users and each have one million active addresses (1 quadrillion funded addresses in the blockchain) the odds in colliding with any address would be roughly 1 in 2^110 (1*10^33).

Vanitygen can produce 20 million keypairs per second.  Lets say you build a super ASIC on 12nm (4 generations ahead of current tech) process that could create, validate, and steal one trillion keypairs per second (1 TK/s). That would be about 50,000x more powerful than faster GPU today.  Lets also say you built a thousand of them and ran them continually with no downtime 24/7/365.   In 1 year you could brute force 3*10^28 possible addresses.  

If there are 1 quadrillion funded addresses you would still have a ~1% chance of colliding with a random funded address in the next 1,000 years.

TL/DR Vlad's answer works.

Chance are negligible. If collision occurs with a funded address, attacker you can transfer funds elsewhere.

Didn't consider that part - if we have no real way of knowing, then the effect should be negligible.

They still affect supply and thus price.
8471  Other / Beginners & Help / Re: So what happens to lost bit coins? on: August 29, 2012, 04:59:47 PM
regardless of how low a rate
..
value should sky rocket?

Lost coins do reduce supply and that (everything else being equal) raises the price because bitcoins are finite. Still your two statements are in conflict.

If coins are being lost at a slow rate then we would expect the price to rise at a slow rate.  If the price is skyrocketing due to lost coins it would be coins are being lost at a very high rate.  Right?

I think the dollar (or "new dollar") will be around in 80 years so maybe I am a pessimist.
8473  Economy / Speculation / Re: Can bitcoins break $5,000 in 20 years? on: August 29, 2012, 04:46:50 PM
We shouldn't be asking when a Bitcoin will be worth X USD, we should be asking when a USD will no longer be able to purchase Bitcoin.

Not in our lifetimes.  The USD may be inflated all to hell where $1USD has the purchasing power of less than a penny and the banknotes are $500 USD, $5,000 USD, $10,000 USD, and $50,000 USD but the USD will outlive all of us.
8474  Other / Beginners & Help / Re: 2nd generation cryptocurrency: Trustcoin on: August 29, 2012, 03:34:53 PM
"mining companies do."

semantics.  gold mining COMPANIES don't have 100% of the wealth in the world and they didn't even when all money was precious metals.

Minting =/= wealth generation.  A concept that you seem to find completely baffling.

Strippers have acquired bitcoins and they didn't do it by mining.  If they can figure it out so can you.

Vladimir actually did create an ASIC and is Matthews backer because he can mine 30 000 btc in 3 days.

Liar.  It would take at least 4.167 days (give or take some luck). Smiley

Theoretically it is possible to mine about 100 800 BTC in one second or less.


Oh yeah.  Forgot about the difficulty lag.

Ok agenda for this morning:
1) get some coffee.
2) do some real work.

It is gonna be tough.

On edit:
DUH.  Forgot difficult won't adjust until the next 2016 block increment so it would be possible.

Bitcoin is weird like that. All the old scams and obvious fraud are now made new again. Surprised nobody here is peddling 'Offshore Trust Accounts' like that guy on talkgold who ran off with a few millions.

That would be tough as Bitcoin is the offshore for offshore.  Smiley

From a Bitcoin perspective it would be like onshoring your wealth.   

8478  Economy / Speculation / Re: Consider Pirate does not pay and does not sell on: August 29, 2012, 01:58:42 PM
Alright lets say you are a grand scheme scammer on the run: What would you rather have: A swiss bank account or a brain wallet?

Occams Razor, pirate was smart enough to come up with his scheme don't you think he is smart enough to take advantage of bitcoins privacy?

I don't think Pirate is smart.  He left a lot of trails both digital and physical.  I also don't think this started as a ponzi (a scam maybe but not a ponzi).  Just a sociopath borrowing more than he could handle at insane interest rates.

I agree a pro would prefer Bitcoins. A couple hundred thousand BTC would go a long way especially if they keep appreciating.  A pro also wouldn't be getting lawyers involved and keep coming back to the "scene of the crime".  A pro wouldn't involve another business entity (GPUMAX) which has other partners that can implicate him. A pro wouldn't do this under the online profile where he has real world contacts (Pirate sold GPU face to face with other members years ago).

If it was a pro there wouldn't even be an announcement of closing.  All contact would simply cease and there would be no trails to follow.  Hosting paid by gift card, IP addresses turn out to be VPN/TOR.  Nothing but a lot of missing Bitcoins.

Then again you might be right, I don't think it really matters anymore.
He won't be affected the market in any material way in either direction.
8479  Economy / Service Discussion / Re: WARNING: Canceling a withdraw on MtGox still counts against AML limits. on: August 29, 2012, 01:49:34 PM
Update:

Speaking with MtGox employees by email their system can't handle exceptions so the cancellation will count against the AML limit.  They have however agreed to put a warning on the cancellation page to indicate that cancellations will be considered a deposit and will count against AML limit.

While it isn't a resolution I like (going to suck that 20% of my trading volume for the next 30 days is blown on a technicality) the warning is an acceptable compromise.
8480  Economy / Scam Accusations / Re: [Resolved] CryptoXChange. No wire in two weeks. on: August 29, 2012, 01:46:25 PM
Update:
Wire received today in the proper amount.   I do give credit for owners of CryptoXChange for accepting responsibility and resolving the issue.  My understanding is they had some of the staff out of town (something as a small biz owner I can understand) and they had a new employee who made mistakes on the wire resulting in it being returned.  The bank account is a business account which may have led to the error.

I would point out that prompt communication and response to trouble tickets could have resolved this without the need to  post it publicly and with less stress on my part.
