For me it had been building the database for 14 hours until it finally worked.

Glad to hear it went well, although it wasnt database building for that long per say. Most of it was spent downloading the blockchain. Database building is around 1-2h with the current blockchain size.

Hey mate,

Thanks for you reply, the current version of armory uses the torrent way of downloading the blockchain and it was blazing fast (was downloading around 30MB/s) for the entire blockchain. It finished downloading in around 20 minutes, then the newer part of the block chain took another 30 minutes or so. It really was just the database build that took incredibly long. And I'm still not quite sure why....
123  Bitcoin / Bitcoin Discussion / Re: Apple Approves Bitcoin Wallets on: June 16, 2014, 02:03:14 PM


whats taking blockchain so long? no word they have even resubmitted

Extremely annoying indeed. Would love a update on this.
124  Bitcoin / Armory / Re: [FIXED!] Stuck building database 99% [FIXED!] on: June 16, 2014, 12:07:14 PM
Managed to fix it myself, here's what I did.


(I am not responsible for any loss of wallets, coins what so ever in any way shape or form)
(Please backup your wallets before doing any of these steps and have a paper backup)



Here's what I did to solve this;

REMOVE ARMORY
REMOVE BITCOIN-QT

After that's done go into the appdata folders of both and remove everything. (blockchain, database, everything)

REINSTALL BITCOIN-QT, do NOT start BITCOIN-QT
REINSTALL ARMORY

now,

Start Armory, do NOT create a wallet (tell it that you want to import one and it'll tell you you'll have to wait for the full syncing process)
Allow everything to sync (this can take nearly forever)
Enjoy armory

125  Bitcoin / Armory / [FIXED!] Stuck building database 99% [FIXED!] on: June 15, 2014, 06:39:03 PM
Hey,

So I have been attempting to build the database on this PC for a while now, have tried re-downloading the entire blockchain twice now and the database 4 times. It's stuck on 99% (1.5 minutes left). It's still hogging CPU resources like it'd still be doing something. I've checked my clock and it's properly synced.

On my other pc's it seems to work fine but this one simply cannot get it running.

I've checked the log file and it comes back with a lot of these:

Code:
-ERROR - 1402809854: (..\leveldb_wrapper.cpp:1787) Invalid txIndex at height 0 index 394
-ERROR - 1402809854: (..\leveldb_wrapper.cpp:1787) Invalid txIndex at height 0 index 351
-ERROR - 1402809855: (..\leveldb_wrapper.cpp:1787) Invalid txIndex at height 0 index 193

Any ideas? I got the full log file available if need be.

edit; Windows 8.1 64bit, 4gb of ram. Armory  0.91.2-beta

I want the official blockchain.info app back in the app store! Currently downloading it through Cydia works fine but I prefer an official app.
127  Bitcoin / Armory / Re: Offline wallet - USB key alternatives - security concerns on: June 13, 2014, 10:51:50 PM
I was thinking, how about a read only SD card?

////////////////////////////////////////////////////////////////////////

Online computer -> Create Transaction -> Load to SD card

Put SD card on read only

Offline computer -> Enter SD card -> Load transaction to harddrive

-Remove read only SD card

-Enter different SD card than the one used before to the offline PC

Offline PC -> Sign offline transaction on the new SD card (the one that came from the old read only sd card)

Take out SD card, put it on read only again

Insert it in the online pc, broadcast.
--------------------------------------------------

This would eliminate the risk of malware being able to write directly to the potentially infected storage device. What do you think?

Great idea!
Except the detail, that the switch is only a flag, and the software on your computer decides to interpret that flag as "read only". Or not.
Newer USB sticks with such a switch are the same, if you can find them.
I believe the older ones with a switch really worked as one would expect: the switch changes something in the usb stick controller to make it impossible for the host computer to write something. I am not 100% certain though.

Ente

Quote
A mechanical sliding tablet on the side of the card (refer to the Part 1 Standard Size SD Card Mechanical Addendum) will be used by the user to indicate that a given card is write protected or not. If the sliding tablet is positioned in such a way that the window is open it means that the card is write protected. If the window is close the card is not write-protected. A proper, matched, switch on the socket side will indicate to the host that the card is write-protected or not. It is the responsibility of the host to protect the card. The position of the write protect switch is unknown to the internal circuitry of the card.

Sadly it appears you are right! Now the question is, is there a solution where the hardware write protect actually does work and doesn't need host protection?

http://en.wikipedia.org/wiki/Write_protection

On the bottom of this wiki article:
Quote
Write blocking, a subset of write protection, is a technique used in computer forensics in order to maintain the integrity of data storage devices. By preventing all write operations to the device, e.g. a hard drive, it can be ensured that the device remains unaltered by data recovery methods.

Hardware write blocking was invented by Mark Menz and Steve Bress (US patent 6,813,682 and EU patent EP1,342,145)

Both hardware and software write-blocking methods are used; however, software blocking is generally not as reliable.[1]

Perhaps?

edit: Some further googling reveals these interesting reads;

http://security.stackexchange.com/questions/4248/how-reliable-is-a-write-protection-switch-on-a-usb-flash-drive

and

http://www.fencepost.net/2010/03/usb-flash-drives-with-hardware-write-protection/
-------

Apparently true hardware write protection does exist for USB sticks. In which case, I change my example to a USB stick with with true hardware write protection instead of a SD card Smiley

129  Bitcoin / Bitcoin Discussion / Re: Expedia, world's largest travel company, now accepts Bitcoin. Your thoughts? on: June 12, 2014, 12:29:30 PM
Just booked a hotel, works flawlessly and much faster than using a creditcard. They use coinbase as backend.

Sweet - looks like it hasn't been fully integrated onto their other domains just yet (eg. Expedia.co.uk etc)

But it's on their main site Expedia.com


Enjoy your holiday LeMiner! Will make my hotel bookings via Expedia too.

They have a market cap of over $9.5Bil in 2013 making it the largest company to accept Bitcoin to date. Though suspect Ebay/Paypal will follow shortly.

2014/2015 in retrospect, will be seen as great merchant growth/acceptance for Bitcoin adoption.

Thanks! It was a hotel I had to book anyway for a trip that was already planned. So why not pay in bitcoins? Smiley. I used the main site (expedia.com) with prices listed in dollars even tough I would normally use euros. I calculate bitcoins worth using the dollar course anyway.

Coinbase did not wait for a confirmation (probably because it wasn't too expensive).  I even got 2 dollars discount as I paid just when the course dropped a bit.

Is the Windows binary pointed to by this link infected?

sgminer-5.0-pre-release-1-win32.zip

Bitdefender reports a virus/threat in the zip file downloaded ... Gen:Variant.Application.BitCoinMiner.11

I've not had a virus warning from any of the other versions that have been optimized for x13 that I have downloaded so far.

*update* - link is no longer active at 18:47 BST


@NiceHash - can we have a dev statement about the probable infection and an update on progress please?

A lot of miners trigger a bitcoinminer virus response in a lot of virus scanners. It's because miners can be installed on infected systems to make them mine for malicious people.

Glad you got out of that ok.

Since you were in a semi-public place, I do recommend filing a police report, there might have been cameras that registered the offenders or what happened. Next time perhaps only meet in a restaurant or coffee place where it's harder to run in or out quickly.

Also, let this be a lesson to everyone, NEVER EVER carry around more bitcoins than you ABSOLUTELY have to, make sure that whatever app you use on your phone has password protection and that you have a backup of your wallet somewhere so you can pull out your coins in case your phone gets stolen.

}

Currently NiceHash is on X13, which makes me believe it's a X13 issue... SGMiner crashes as soon as I get the GPU 0 1 2 3 4 5 window (where it normally shows hash rate). Before I got it to work a little bit with X13 but it showed similar hashrates as in Scrypt, the only file generated when I attempt to start it up is the one from ckolivas.

Any ideas?
