blockchain.info? Best part is you don't even need to trust them Smiley

Well yes. It took me about 15 minutes to get to 5 digits...

Wow - guess my laptop computer is rather slow then. Sad


I played around with vanitygen, and from my experience it appears that the length of custom text you want isn't important, some addresses just took longer to generate than others, regardless of the number of vanity characters.

The algorithm is really "dumb", it just generates addresses and stops when it finds one that matches the pattern. Difficulty grows with length (imagine trying to find a certain address from first to last digit, chances of finding it are almost non-existent), but there's quite a bit of variance in this, it might take 1 second or it might take 1 hour to find the same pattern (just like block mining).

It ran on quite a decent GPU, so there really is no comparison Smiley

Thank you.
you will not be able to get 7 digits though.
Isn't this a matter of time and key generating power?

Well yes. It took me about 15 minutes to get to 5 digits, I imagine it would take quite a bit longer to get to 7. But I guess it can be done, eventually.
But as I said, I wouldn't trust anyone else with this, so do it yourself.

you will not be able to get 7 digits though.

Also you will not be able to get an address without a private key, therefore you're risking loosing everything on it "buying" this from a third party.

May I ask why this is not supported on HTC Desire (Android 2.2.2)?
It requires Android 2.3 or higher.
Oh, ok, this should be corrected on the list of supported devices then. Too bad, I'd love to try it out.

you got your name right:)

Now I don't quite understand what do you mean. Isn't it normal to ask for about $500 loan from the markets?

If you're willing to provide ID, place of employment, telephone number etc. maybe.

51% Attack --> ?? --> Profit!

Profit from what exactly?
210  Bitcoin / Bitcoin Discussion / Re: Blockchain.info Wallet - ERROR! on: April 27, 2012, 12:48:21 PM
Try restoring your wallet from backup?
211  Economy / Trading Discussion / Re: pirateat40's end game on: April 24, 2012, 10:21:28 AM
This scam can probably last until he gets 51% of the mining power. Then use whatever money is left in the BTCST accounts and do a 51% attack against mtgox and other exchanges at the same time. Then disappear with all the money. What do people think? Far fetched or possible?

Can you explain what exactly is a "51% attack against mtgox", please?  Roll Eyes

Alert:

A bug has been found in the payment script that has caused some issues with the last payment.  It will be corrected shortly and any adjustments in payment will be credited or sent to you.

Thanks,

Has this been corrected yet? Not that it matters much but my last payment is still a tad shy of what it's supposed to be (thus some kind of bug still being there).
213  Bitcoin / Development & Technical Discussion / what is going on with testnet network? on: April 13, 2012, 06:37:17 PM
Now that I've finally managed to set up testnet there are almost no new blocks... What's happening? What can I do to speed it up? I've tried using the latest bitcoind but it wouldn't catch up with the proper chain.
214  Bitcoin / Development & Technical Discussion / Re: BitcoinJ - Error on: April 13, 2012, 08:42:45 AM
http://mvnrepository.com/artifact/org.bouncycastle/bcprov-jdk15/1.46
215  Bitcoin / Project Development / Re: BitcoinJ Maven on: April 12, 2012, 02:35:33 PM
testnet rules from bitcoin-QT (satoshi client) have changed and those rules are only in 0.5-SNAPSHOT or in one of the upcoming 0.5 releases

Thanks for the help, tried that, but it still won't work (at least not consistently). Looks like it depends on the peer it connects to, sometimes it downloads 50k+ blocks and sometimes only 47k. Meh, I think I'll go with the way Jim uses.
216  Bitcoin / Project Development / Re: BitcoinJ Maven on: April 12, 2012, 08:58:35 AM
Jim, just one more question, does the testnet work at all (I'm using bitcoinj 0.4, that's what's in the multibit pom also)? I get stuck with 7539 blocks to go... I'm guessing the change in the testnet difficulty rules might have something to do with that?
217  Economy / Lending / Re: Offering monthly deposits with 10% interest on: April 11, 2012, 08:22:28 PM
This is exactly what is wrong with the society today: too many middle men trying to get rich of others with doing nothing. If this is indeed the case and you can't lend to pirate directly you can lend to me and I'll give you your fair share of the profit. People like this make me sick.

In any case, I don't think that once you have an account you can just throw any amount of money into it and expect interests, makes no sense at all.
INAU pays way more, too.  Huh

15% monthly insured, 30% uninsured.

fair enough, invest with him then Smiley (but whenever someone tells me something at this rate is insured alarm bells start ringing in my head)
218  Economy / Lending / Offering monthly deposits with 8% interest on: April 11, 2012, 08:02:28 PM
I am willing to pay 8% on monthly deposits. Like many others this also is a Bitcoin Savings and Trust passthrough operation.
In case of Bitcoin Savings and Trust not being able to pay interest anymore the funds would be returned to you prematurely, with a partial interest payment.

About me
I have been a member of this forum for almost a year and from that time on I have been living for bitcoin. I have made some loans myself, as it can be seen from the OTC rating in my signature. Currently I'm trying to contribute and am working on an opensource implementation of CommitCoin (bitcoin timestamping protocol).

edit: nevermind, I changed my mind. Not worth it.
219  Bitcoin / Project Development / Re: BitcoinJ Maven on: April 10, 2012, 06:35:49 PM
Hi vuce,

I see from your previous posts that you are working on a prototype for commitcoin.

Feel free to reuse any of the multibit code for the bitcoinj side of things if it saves you time. It is all MIT licence.
You might be interested in the MultiBitService for a bit of network abstraction or the various actions (it should be fairly clear from the name what they do. The ones with the Submit in are the ones that actually perform the task).

Jim

Went through the code, it will certainly come in handy. Cheers!
220  Bitcoin / Project Development / Re: BitcoinJ Maven on: April 10, 2012, 09:53:41 AM
your error message means that
Code:
SECNamedCurves.getByName("secp256k1")
returned null.

Propably you have the wrong BouncyCastle lib installed. the version used in BitcoinJ is 1.46 (see pom.xml)

you Sir are correct. Thanks a bunch!

MultiBit uses bitcoinj via Maven so you should be able to use the POM for the dependencies:

https://github.com/jim618/multibit/tree/v0.3

Note also that bitcoinj runs it's own repo so you need to have a couple of entries in for that.

There is quite a lot of 'packaging cruft' in that POM so let me know if you have any problems.

I have multibit pointing at the last stable release (0.4) but you might want to sit on the bleeding edge and go to 0.5-SNAPSHOT.

Will check it out, thank you so much!
