I suggested a variant here -- there still is proof of work, but only by nodes authorized by a master node which has veto power over any blocks.

The question is should I be concerned about it ? Has anyone else received strange phone calls to numbers that shouldn't receive them ?

Last year for several weeks after the runup there was a string of some very weird contact I had received, including PMs on IRC and a couple on the forum that were definitely trolling. 

The one that had me baffled though went back and forth through e-mail about five times before I finally figured out it was not due to either trolling or anger but instead the result of a horrible job done by Google Translate.

As far as methods used though, my contact info is easily googled.

i actually thought it was interesting that Frisby mentioned Bitcoin exactly 3x but Schlichter refused to talk about it.  i had thought he was a convert but i may be mistaken.

Maybe then Detlev kept quiet as he would like a second invite some day.  :-)

Is there a project already of any kind that lists our reach for regions and languages? Like a checklist per country of availability of local(ized):

There is no Persian version of the Bitcoin wiki yet.  Anyone can champion that effort though.

For some of the apps and sites, all that is needed are string translations and support will be added.  Some of these that have active efforts to expand translations include Bitstamp, and BitcoinNordic (exchanges), Bitcoin.org and MultiBit (clients), Bitcoin Spinner, Paytunia (online and mobile wallets) and SatoshiDICE.com (merchants).  There are more, these are just examples.

There is an Iranian digital currency exchange:

 - https://karsha.biz/?do=contact

Also, BitcoinNordic.com now accepts CashU cards, which is used in much of the Middle East.  It looks like years ago they had locations where the cards could be purchased in Iran, but not anymore.  Just thought I'ld mention it though in case it is relevant.

Lastly to get BTC to for example Iran there needs to be something to sell from these countries. IRR are not really useful for anything outside of Iran so Iran would have to export something else in exchange for in-flowing BTC.

Bitcoin is suited well for use by tourists and for business travel.  Suggesting that bitcoins can be used to exchange locally for IRRs gives the traveler the ability to not have to carry much cash while traveling there.    Also, at internet cafes and other places where gamers and techies are found, sometime online and in-game transactions will allow purchases using a voucher method and then Bitcoin available for withdrawals (e.g., Second Life Lindens on VirWoX).

There are no doubt thousands of opportunities missed daily because Bitcoin are not widely known or available yet.  All it takes though are for a few developments to get things started and then progress can build from there.  For instance, I once handed over a fraction of a bitcoin using a paper bitcoin created by BitAddress:
 - http://www.BitAddress.org
The coin from that paper then was sent via coinapult through e-mail to someone else, then through InstaWallet to another party before finally being spent on a game of chance. At least four people then learned how bitcoin can be used and one later invested in a small amount after reading up further.

But it takes a catalyst, and people like us -- who can see the potential, and effect change to move bitcoin forward, are it.

[Update: A Farsi translation for Mutibit has been released:

5225  Bitcoin / Bitcoin Technical Support / Re: Multibit transaction not confirmed. Not according to the block! on: July 24, 2012, 10:09:45 AM
I am not sure if there is any way to 'override' a transaction that is already out there - perhaps a miner reading this thread would know better as to what works.

There was a proposal by a bitcoin.org core developer that would do something to the effect of allow any party to add to the fee paid for a transaction.  I don't think it got very far, and definitely isn't implemented today.

The only thing you can do to help a transaction get confirmed is to leave the client running if there is a chance the problem is the transaction just didn't get propagated and that the client would rebroadcast it.

Has doublespend ever been executed successfully, even as an excercise?

Attempts? Every day.

 - http://www.blockchain.info/double-spends

Successful?

You can approach 100% success at double spending on 0/unconfirmed, if the recipient is vulnerable due to the configuration (accepts incoming transactions, static IP).

  - http://eprint.iacr.org/2012/248.pdf
  - http://bitcointalk.org/index.php?topic=79090.0

When bitcoins are received and then lost because of a double spend, the transaction will usually eventually disappear, so there may have been successful 0/unconfirmed double-spends without the recipient even knowing (unless the change to the balance was detected.)   Even a successful vector76 attack leaves (where there was 1 confirmation) disappears, unless those coins too were spent.  This is what appears to have happened to a smaller exchange a few months back which discovered a spend transaction that would not confirm.  The reason that happened was because the input used was received just one block earlier and ended up being a double spend.

The bets and payouts will be conducted here on the forum because we want 100% transparency. No website.

It is too bad that his type of betting category is so time-critical, as a blockchain-based betting approach would otherwise work so well (transparent, real-time visibility).

We are only weeks away from launching this, even sooner!

Looking forward to it!

After looking into UKash after seeing BitcoinNordic's support for that payment system I noticed a service that promotes itself as "airtime across borders".
 - http://www.transferto.com/international-top-ups-countries

They use UKash voucher codes as the payment system, so there is a pretty hefty charge to the user.

There is plenty of room for a bitcoin-based competitor!
5229  Local / Other languages/locations / Re: Vietnam - All here on: July 24, 2012, 04:00:16 AM
Now that BitcoinNordic.com accepts payments using CashU, and UKash vouchers can be used to fund a CashU account, this may provide a method for purchasing bitcoins in Vietnam.  At one time, Vietnam was one of the countries shown on UKash's website though now I can't see any references to it, so perhaps it no longer is (or never really was) offered in Vietnam.
 - http://en.bitcoin.it/wiki/UKash

Is UKash available in Vietnam?

Also, I happened to notice this article about a crackdown there on mobile phone users, requiring a verified identity.  

"Police check on 5m mobiles"

"[The reason is] an attempt to rein in the number of subscribers, many of whom have more than one phone so that they can take advantage of special rate deals.

However, a senior policeman, Major General Nguyen Cong Son, said many criminals took advantage of mobile phones for illegal activities, including sending hundreds of messages "scamming" for reply fees,"

I'm curious what a reply fee is.

5232  Bitcoin / Bitcoin Discussion / Re: This is HUGE: WIKISPEED, first car-maker in the world to accept Bitcoin on: July 23, 2012, 08:33:44 PM
OP here.

We are very excited about this.

[..]

I will be glad to answer any questions, just go ahead and ask.

Rocky, your work in support of Bitcoin and the P2P economy is fantastic.

I see that one of the principles of Wikispeed is equitable distribution of wealth.  (with interest paid to those "investors" whether the investment is in the form of "money, time, cookies or supplies").  How does Wikispeed gauge each person's contribution once there is wealth to distribute?   (Is there some ledger?)  

I have an idea that I wonder if there would be interest in.

Raise $18K USD worth of funds for the purchase of a completed Wikispeed C3 using GLBSE.  So this is no different from pre-selling, like what you see on Kickstarter, except that because the amount of money involved, individuals would pay in advance for just a fraction (share) of a Wikispeed C3.

Then once that vehicle is ready for delivery, it is sold by auction.  The first opportunity for bidding is given exclusively to those who bought shares directly pre-IPO (they can sell their shares through the exchange after the IPO but they retain the ability to enter the auction, that right does not transfer with the shares).  If that auction results in no bids above the $18K USD purchase price (in terms of USDs) then the vehicle is auctioned off to the public.  Shareholders then receive the proceeds of the auction.

This is a bit further down the rabbit hole than the simple pre-selling like what you see on Kickstarter because it is not a direct 1:1 consumer-supplier relationship.  So I doubt this approach would be possible without going the GLBSE route (at least not for a quantity 1 and a relatively smallish total amount ($18K) involved).

I wouldn't be the right person to set this up on GLBSE, but I'ld be willing to buy a few "shares" in this.
5233  Bitcoin / Bitcoin Discussion / Re: This is HUGE: WIKISPEED, first car-maker in the world to accept Bitcoin on: July 23, 2012, 07:35:34 PM
Huge news, awesome. The bitcoin address is shown in the press release, but doesn't accompany the "bitcoin accepted here" logo elsewhere on the site, as far as I can tell.

The home page has a bitcoin graphic, but no click on it yields the address.

The press release is hosted on their site:
 - http://www.wikispeed.com/wikispeed-team-blog/wikispeed-first-car-maker-in-the-world-to-accept-bitcoin-press-release

The page isn't protected with SSL ( https:// ) though, which makes it vulnerable to a man-in-the-middle attack (in which the attacker replaces the bitcoin address and nothing else, and pockets the free bitcoins).

Looks like a few bitcoins contributions have occurred:

5234  Bitcoin / Bitcoin Discussion / Re: Collecting BTC equivalent to collecting Real Coins of Historic Value? on: July 23, 2012, 08:24:49 AM
the first coin ever minted and the last coin ever minted would have some sentimental value for many

especially if it was never used etc

the coins from the genesis block were destroyed

They are unspendable by the current client.  Presuming Satoshi still has the private key, this could be fixed along with other changes in a hard fork change
5235  Economy / Trading Discussion / Re: Idea: BitcoinTunes on: July 23, 2012, 08:00:56 AM
Receipt of payment and download is generated, so whoever tries to initiate chargebacks will run up against the proof they received the MP3.

The problem is PayPal doesn't care if you can prove shipment or not.  They have a tactic to keep bitcoin out of their hair for now. Bitcoin is competition to them.  They probably aren't going to want to even listen to how you can prove the digital goods were delivered.
5236  Bitcoin / Bitcoin Discussion / Re: Collecting BTC equivalent to collecting Real Coins of Historic Value? on: July 23, 2012, 07:50:07 AM
I bet when the network reaches capacity any virgin coins unspent will be worth more and more value to a collector.

Not really, because they cannot be transferred and remain valuable.  If you simply hand over the private key the collector might not trust that you won't spend the coins.  If you make a transfer, that changes the coin from uncirculated to almost uncirculated, night and day difference.  :-)
5237  Economy / Web Wallets / Re: Blockchain.info - Bitcoin Block explorer & Currency Statistics on: July 23, 2012, 05:13:02 AM
I see that the DNS for blockchain.info supports SPF (for helping to ensure the message wasn't spoofing) but it appears misconfigured.

It currently explicitly includes mail coming from uservoice, but the notifications are sent from a host with blockchain.info in the hostname, so the SPF check results in a soft fail as blockchain.info isn't included as one of the hosts that should be sending mail for this domain.
 
5238  Economy / Speculation / Re: I have made a 25% return this week trading *against* the pirate on: July 23, 2012, 04:10:16 AM
He makes each swing happen by using a small amount of funds to drive the price down and a larger amount to drive it up. The hyper-reactive lemmings do most of the dirty work for him by accepting the new price he sets and push the trend up or down farther than pirate has funds for.

Whatever the cause, there sure is some absolutely idiotic trading occurring.  A good chunk of the sell volume occurred at the price at the bottom when it was dumped followed shortly by buying occurring mostly at prices at the top end when there was the spike.  Volatility of 15% in a matter of hours is not sane trading by anyone, if that was the same party pushing both directions.


 - https://ferroh.com/chart?t=24h

Also, left completely out of all of this were the other exchanges.   The trading at Intersango. BTC=e. BitFloor, CampBX. etc. was minimal.  None of them spiked to levels anywhere near what the markets on Mt. Gox did.  This is wasteful lunatic selling and buying.   It is making great money for anyone that didn't panic though (and who panics nowadays anyway, with no leveraged trading options after Bitcoinica is gone, the exchange rate seems to always return to a certain trajectory).
5239  Economy / Currency exchange / Re: USD between MTGOX <--> DWOLLA on: July 23, 2012, 01:27:59 AM
I just realized, that a person might not necessarily need to have a Dwolla account to do a trade like this.   With Camp BX, for example, I can specify the Dwolla account number that I want to withdraw to.  I don't know for sure but I can't see any reason they'ld check to make sure it is my Dwolla account that I'm withdrawing to (especially since Camp BX doesn't have anything more than my e-mail address) though I have deposited to Camp BX from my own Dwolla account many times and these two wouldn't match.

Can anyone confirm that Camp BX (and Intersango) will withdraw to multiple Dwolla accounts (one at a time, of course, but over time each withdraw to a different Dwolla account) without requiring the exchange account become verified?
5240  Economy / Speculation / Re: The Weekend Dip Myth on: July 22, 2012, 11:27:02 PM
Yeah it was huge!! Why we started at 8.50, and now we are at 8.50.  

The "official" weekend dip theory (at least the one I ascribe to) only is used during a selloff trend.  i.e., because currently the high for the previous seven days (as-of Wednesday evening west / Thursday morning east)  exceeded the highs in the seven days prior, then there was no prediction of a dip or no dip.

That being said, there is a clear pattern lately that buying on a Saturday or Sunday, particularly after a little mini selloff like where we are at right now, is something that pays off a day o two later.  As new money (wire transfers, Dwollas, cash deposits during banking hours, etc.) arrives, the impatient buyers buy the coins at whatever the price happens to be it seems.

I've no idea if this pattern will happen yet again, and no idea what the price will be on Monday or Tuesday, but seeing all the ways people are using bitcoin today and seeing the variety of stuff being built for Bitcoin, tells me that a month or three from now there are going to be a whole lot more people finding bitcoins useful to them.  So a weekend dip or not is really not something relevant looking even just weeks down the road.

I do recommend, however, that Da Dip should be watched at least once every weekend!
