Probably it uses fsync's at each write or somehow disables write cache in another way. System has really big iowait values when downloading whole  block chain (i'm about linux).

ни на какие. просто валидные транзакции. если убрать транзакции генерации, это ничего не изменит. график просядет на пару %

и заметь, на пике пузыря было 14к транзакций в сутки.

If this mtgox application will be futher elaborated, bitcoin could hit mobile payments market in a future.

Well, the bitcoin client not just downloading, i verifying each block. And blocks can not be verifyed from the end. Because block hash can be verified only if you know previous block hash.

So downloading from the end is a wrong way.

p2p currency will never have instant confirmations without significant CPU and network load. Then smaller confirmation time - then network is more insecure. I dont imagine how this can be resolved.

I own a small bitcoin exchange and I saw that new non-technician user have strong difficulties to start using bitcoin.

N1. Downloading full block chain at first launch disappointing clients. There is no any warning that block chain is not up to date, so users ensure they can start using it immediately. The typical dialogue:
I: I have sent you bitcoins
...few minutes....
Client: Still not get it. How long bitcoins are come?
I: What is your block counter shows? How long ago you launched your client at first time?
Client: 5000 blocks, I have launched it 30 minutes ago.
I: You have to wait while block count will reach XXXXXX block, then you will see your transaction
Client: How long it can take?
I: 8 hours or more
Client: OMFG

N2. Confirmations. 10 to 60 minutes is too much. But... I do not think this can be fixed in any way.

N3. Wallet backups. Non-technician user does not understand one point in backups. If he backup his wallet, then generate a new address and receive funds on it, and then restore his backup, the funds received with new address will be lost.

As for N1 - this is very, very big disadvantage. I think it could be fixed if the network will provide last block height, so bitcoin client can compare it with its current highest block and display a warning that block chain is not up to date and a serious transaction delay may occur.

Дело было вечером, делать было нечего. Пустил парсилку цепи блоков в формат мускуля. Получил данные с 15 июня 2011 по 9 октября 2011. На это ушло пару недель работы ноутбука. Одно из двух. Или я не умею правильно юзать беркли, или беркли нереально жоский тормоз.

Так вот. Сравниваем графики курса mtgox, дневного количества транзакций и дневного оборота. Последний оказался практически бесполезным в плане предсказания курса.

А вот дневное количество транзакций в таком масштабе позволяет говорить о том что нетворк в депрухе. И пока выходить из нее не собирается.

Любуйтесь на здоровье.

I have parsed block chain from 15 Jun 2011 till 9 Oct 2011. Why... why Berkeley DB is so fu**ing slow??? It took two weeks and still parsing because i want to get deeper data.

But.. intermediate graphs are here. So, I am about to compare exchange rate to daily transaction number and daily transaction volume.

The daily transaction number is the major bitcoin network activity and popularity marker. I didnt find any useful data in daily volume graph.





Well, I do not see any bullish trends here. Network is depressing (as i told you 5-6 page posts ago). I dont exclude that network activity will raise in near future, but now it is under depression.

ps. to be concluded >>>>

Okay, another one on the way )

Ага. Доставили прямо к дому. Только почему то доставщиков было 10 человек, все были в масках. Агрессивные какие то. Стали бить и задавать вопросы. Тыкали какую бумажку на подпись. И посылку себе забрали. Шо за пиздец? Плохой магазин. Не давайте ему денег!

Комиссия снижена до 10%.

I've seen this before...

NASDAQ 1992 - 2002


USD/BTC 2010 - 2011

While speculation makes major turnover, bitcoin price will fall.

I think new wave of popularity is coming, which will inflate this bubble again.

bullshit your triangles, sorry.

While we have bitcoin turnover consisting of mtgox trades (trying to fool each other), this bubble will defalte.

Big torpedo for big ship 

Wow. There is no that wall anymore...

Still there ))

Jackpot 8.4162 BTC taken by someone with nickname  "YES". Congratulations!

>20k btc wall @4.45 btc

Looks very ominously....

Медвежья стена на 20к btc @4.45, и мертвые с косами стоят.... И тишинаааа...

Выглядит как то зловеще...

По моему бомба. Кроме трейда и графиков, можно оплачивать всякую хрень уже со своего акка Mt.Gox.

Короче, +100500
