81  Economy / Trading Discussion / No ID exchanges? on: August 31, 2012, 10:38:34 AM
 Which exchanges have automation/API but don't require ID for bitcoin withdrawals?

ID required for fiat withdrawals is ok with me, as long as I can withdraw BTC without too much hassle.
82  Economy / Goods / UK Spare Mobile phone bundle for cheaper everything (data,int calls, uk calls..) on: August 29, 2012, 02:13:59 PM
Ok, I'm just gauging interest and I have a daytime job so I might be slow to service here, or it might be great and fast. Just to let you know on the disclaimer there.

If you have a contract to work out if this is better try using the following rule of thumb:

- divide the number of "free" cross network minutes but the price of your monthly calls.
Now ask yourself, do you actually use exactly that amount of minutes each month?
Now add in the ability to resell the phone they give you and whether you can if it's locked.

You should find that this deal is cheaper for everyone. Try me!

The suggested bundle is:

- simcard. For cheaper UK mobile calls
- calling card with access number. For cheaper international calls. But since the calls to the calling card are free you can also use this for cheaper domestic UK calls.
- unlocked phone. I've found a nice cheap unlocked blackberry style phone. More durable, less to worry about at a festival or dropping it in an engine bay

Prices all decided at point of 6 transactions by Mt.Gox £ rate:

- £7 for a £5 calling card for you to test
- simcard & £15 credit = £20
- £25 for the phone
- £5 postage

So in BTC that would be:

(thanks btcticker)

Using the access number, sample international rates:

UK-Aus 2p/10p
UK-Bangladesh 2p/3p
China 1p/1.5p
India 1p/1p
Nigeria 4p/6p

Direct mobile calls are cheaper than contracts too:
UK-UK via access number 2p/8p
UK-UK mobile without awkward access number 10p
UK texts 6p
Voicemail 8p/call
Internet = <20mb = 20p/day but you can buy "unlimited internet" for 1 month for £10 with minutes free with that(whatever the heck that is... assuming at least 1-2gb I would hope)
0800 - free; pretty damn useful

While on holiday in Europe is cheap too:
- receive call 7p/min
- send txt - 8p to UK
- receive text - free as usual thank god
- roaming data in EU - 69p/mb (sorry. it's actually pretty good for easy access)

Need spare unlocked phone to go with it?

£25 = Cheap unlocked,
 Chinese blackberry keyboard style phone,
 Very basic but has a version of Opera for Facebook and email. Battery lasts longer than the typical Android.
No recognised O/S but
standard micro usb charging and standard headphone socket and I've used it in Norway no problem.
Much more useful to carry around than worrying about your Samsung note getting mugged & scratched at work.
Only drawback is GSM 900/1800 only, can you see a gap in coverage:
http://en.wikipedia.org/wiki/GSM_frequency_bands#GSM-900.2C_GSM-1800_and_EGSM.2FEGSM-900


 I've been travelling on work for years now and this is the setup I'm using. It's taken many years to get to this point and I'm quite chuffed with it.
83  Economy / Goods / Tesco UK GBP £100 gift card for Gox +7% on: August 29, 2012, 11:46:43 AM
Mt.Gox GBP spot rate + 7% @ time of transfer for ~6 confirmations.

Postage has to be recorded to a UK address.
Special delivery is currently £5.90.
2nd class recorded is currently £1.45 but you only have £46 insurance with that.

i.e. today £100 = £107 for the fee, £112.90 for the insured postage x 7.1011 Gox rate =  15.7722043064 BTC

Also, I reserve the right to withdraw the offer and reverse in the event of wild rate swings >30%

Tesco sell all sorts of things and everyone's got to eat so I hope this is a helpful cashout option now for UK people, especially with Intersango in flux & ID requirements and charges from Gox.

84  Economy / Trading Discussion / Exchange account solvency on: August 24, 2012, 02:47:31 PM

 What banks do the various exchanges use and how solvent are they?

Some banks in Europe are obviously going to be pretty shaky. I wonder if Gox's accounts in Japan are any better, or whether that is just as exposed since Japan is pretty linked to the west anyway.

Seeing as Bitcoin for many is part of an emergency store of wealth ready for problems with the various banking systems, and many are speculating, I thought it an important question.
85  Other / Off-topic / Serval & mesh networks revisited on: August 19, 2012, 09:31:10 AM
http://www.servalproject.org/

I don't know about you but I'm noticing we're slowly losing the internet. i2p & tor are greaat but I think really anything piggybacking on current infrastructure is a bit of a loser.

Serval is the closest thing I've found to a decentralised network. But it's far from great.

The main problem for me is that afaik it doesn't cache messages. I'm surprised there isn't an app out there that can cache and forward bluetooth messages for example. Did I miss something?

The subject has been mentioned a few times before:
https://bitcointalk.org/index.php?topic=6477.0
https://bitcointalk.org/index.php?topic=41460.20

Isn't there anything more basic out there? Something as simple as an app that scans over bluetooth sending, recieving & forwarding messages?
86  Economy / Service Discussion / SSTP VPN on: August 13, 2012, 02:03:51 PM

 I've found a few VPN's offering SSTP but they all want identity or a traceable payment. I'll give in to this if I have to but I'd prefer Bitcoin and no questions asked.

 Any recommendations?
87  Other / Off-topic / Brainwallet for PGP? on: August 09, 2012, 02:43:00 AM
Just seen Brainwallet.org Rather clever.

I wonder if that (or a Bitcoin address) could be used for general encryption as well?

Can a memorable phrase also be used to store a PGP key?
88  Bitcoin / Mining support / Mobile mining - dual use & latency on: August 08, 2012, 05:50:32 PM
First, what about the possibility of being able to use a rig for something else like password cracking.
Do you get that with ASIC or is that only possible with FPGA?
Which boards can also be used for other purposes? I'd love to be able to switch to cracking a WiFi password if I wanted to (or vanitygen).

I ended up giving up on waiting an cancelled my Paypal order from BFL because I couldn't budget for the unknown wait time.

 I get free electricity in some locations but the latency could be high. Is there a graph of latency to stale shares somewhere? Can you tell us how you get on with this?

 At first I thought perhaps I could just:

1) buy a BFL single,
2) carry it with me,
3) plug in wherever and
4) connect over anything I can find (3G, WiFi).

This would have the advantage that I can carry the miner with me and unlike gold or cash it hopefully looks like a hard drive so hopefully less chance of getting it confiscated and if things change I can settle it down somewhere more permanent.

However,
1) the tech is moving so fast and preorders are now the norm I don't fancy speculating that much.
2) Only the BFL single seems portable.
3) Plugging in would also need something like a Raspberry Pi. The location would have to be secure. I don't really have my own place to put things at the moment but I do have plenty of places where I plug in a laptop and I'm allowed to use the electric because in a sense I'm paying for it already.
4) Latency I hear could be a problem... but how much? Places I might plug in include satelite (1300ms) South America (400ms to nearest pool?) and Europe (~30ms). I wonder what the likelihood of stales are. In Europe I'd be paying the most for electric but on satelite & south america I should have access to solar panels and wind power. Is the effect greater with solo mining? Why don't more patient people solo mine?

5) The tech is moving so fast I wonder if it's really worth it...?

edit: Also, what's this Jalapeno? Looks like a trade-in? Too cheap?
89  Economy / Service Discussion / Careful with Blockchain.info MyWallet if using 2 factor auth (recovering .json) on: August 08, 2012, 11:57:28 AM
So... the battery fell out the back of my phone as I was about to change the SD card and I ended up having to wipe everything and do a nandroid restore.

As a result I lose my Google Authenticator setting for Blockchain.info MyWallet

Now, I used the email backup so I have the .json ready to restore. But how do I do this?

https://bitcointalk.org/index.php?topic=93040.0 mentions this but not with 2 factor auth.

I've requested manually recovering but no word back yet.

I got this off ebay because I'm used to blackberries and I hate writing on a screen, waiting for the screen to rotate and pulling out a damn side wards keyboard every time I want to write a quick reply to an email!

Got from ebay and you can test it but I haven't got a spare USB charger. It's a standard micro USB one. We'll test it with your SIM.

The corners are scuffed but the rest is fine as far as I can see.

Its unlocked and I'm using it on Three at the mo.

it actually has 11 bands so its very good for traveling and using local simcards.

I got a uprated battery for it from a reputable company rather than an unbranded Chinese fake and this works well. The only negative in the reviews previously was the battery capacity so this is good.

I looked at other portrait keyboard phones but this was the only one with a decent review so I had to get it shipped in from America. The key thing is that its no different and in fact just adds more band support. we can test it with your simcard. I've used it with Of and vodafone too.

I have a custom ROM on it at the mo so no Motorola bloat ware draining the battery and spying on us. Its a GB release. ICS wasn't ready for me but looking at progress there I think that will be stable soon as well.

Specs are almost the same as a galaxy s1, which is only really 5MP camera and single core CPU away from a galaxy s2.

I wasn't intending to include a charger but I can give you one if you really need it and I'll just use a USB sync cable for charging my other phone instead.

91  Other / Off-topic / Similar to DeSopa on: July 31, 2012, 10:36:46 AM
I just wondered...
 is there a Firefox addon out there that can swap DNS requests for IP requests without using the hosts file?

I don't have local admin on this machine to alter a hosts file. I tried DeSopa but it didn't seem to make any difference.

Firewalls I'm stuck behind are SonicWall and DansGuardian. Even parts of Slashdot are blocked... and it's one of the few things to do all day...
92  Bitcoin / Bitcoin Discussion / Defeating Rubber-Hose Cryptanalysis on: July 30, 2012, 03:28:14 AM
 I wonder if there should be a forum dedicated just to security...

I'm sure you're all familiar with


 How to deter?

Idea 1) Steganography

Idea 2) Additional factor: Share the private key between 4 execs. 2 of the group are required to decrypt the code. 4 not 2 in case one of the pair dies.

Idea 3) Time based auth. Have a factor that only becomes clear when a certain time happens. Hard to implement in practice? Could it be something such as how light falls on the earth or something stranger? How could this work in practice?

Idea 4) p2p auth. Need a peer to peer network agree and get concensus to decrypt the key.

Idea 5) Deniable encryption. Like carrying 2 wallets, one low value. Can't see this workingm they might be able to tell you are lying.

Idea 6) Do something funny with public key encryption?

Idea 7) Just bury half of the key somewhere awkward to get to. In another country perhaps. If you had a yacht and got captured would this deter or would you really want access to that for a bribe?


Anything else? How to make these things more workable? Is there a way to give a 3rd party access to a wallet in such a way that they can only pay out to an address you hold? That way you could give grandma/wife half the savings and get an allowance so you can't go gambling.

94  Other / Off-topic / Android do it all ROM, how much is it worth to you? on: July 27, 2012, 06:19:06 PM
 How much extra would you pay for a Galaxy S I,II or III with a ROM & the following security/privacy related enhancements which would never see the light of day from a major manufacturer:

1) Outgoing call recording ( http://androidcommunity.com/record-calls-on-your-galaxy-s-20110225/ )
2) Permissions management at the ROM level ( forum.xda-developers.com/showthread.php?t=1774549 )
3) Open source ROM except for a binary blob for the modem ( i.e. a bit like www.replicant.us )
4) SEAndroid ( http://selinuxproject.org/page/SEAndroid )
5) Tor bundled and working
6) Possibly a VPN setup already and working
7) Maybe some kind of alternative tunneling setup on there
8 ) Backtrack5 already on sdcard and ready for testing WPA with Reaver already available
9) Something to help get apps from Google Play onto the phone without having to install GApps
+ possibly some pirated apps that have been thorougherly tested.

I'm finding it too hard to get all those things working in a single ROM. Now I'm looking to pay.
I'd pay $300 extra but only if it had all of those features setup for me and from someone reputable.  

Sorry, keeping it simple so no other phones please. I'd also ask the same for iPhone but I don't think many of those things are possible on iOS, even rooted.

96  Other / Off-topic / Credit unions and Bitcoin on: July 14, 2012, 10:05:37 AM

 I've seen a few threads around this but many are old and I didn't want to necrobump them.

When you talk about starting a bank many give up before even fully looking into it.

 There's actually a lot good pieces of news in the area:

1) A full banking license actually can cost as little a ~$2m. If you base out of the right place it's very doable.
However, putting banks aside...

2) You can pay your £/$/€ fiat wage directly into a credit union. You can also pay your bills directly too.

3) A credit union can easily issue debit cards but that's not essential


How do you think Bitcoin fits into the picture bearing in mind the work going on with the likes of Grassroots Banking movements?

I could imagine a Union which:

- allows you to adjust how much of your balance you wish to keep capitalised or to invest - and unlike banks it's upfront about it! Fees cover the capitalisation
- links with various exchanges seemlessly (goldmoney, various Bitcoin exchanges)
- facilitates currency exchange directly between members (like Zopa)
- links with other exchanges globally using Bitcoin
- issues a Debit card with a QR code on one side but usable in a normal ATM machine!
- automatically converts a % of your wages to a credit based currency such as precious metals or Bitcoin, optionally even transfers these funds abroad

Just how many of these processes you want in one basket is another matter. Obviously something too useful for capital flight and successful would be persecuted by the banks but,

 this surely is a business ripe for development!

Already this is possible separately but it's clunky - the mean thing is that you just need cheap transfers from Union to the exchange. That's the key, cheap transfers. If you're in the Eurozone then that means SEPA.
Also, a credit union can potentially be as bad as a bank. There needs to be a union with strict controls on capitalization or it's just a bank by another name! You could even have limits on what can be deposited.

The other problem of course is the fees. If you are keeping a well capitalized balance sheet then you're not investing funds elsewhere to pay for the fees. What are the overheads for running a credit union? I heard it can be <$20,000 to start in the UK, but what about ongoing fees? I would have seen this as a big thing before- people don't see the fees in banks until the funds disappear. However, now is a time when people are waking up to this.

The whole thing could be non profit and tax exempt, kick started with crowdsource funding.

I think any credit union needs to be careful when associating with Bitcoin. Ideally you'd want to have these things as 3rd party services but aiding automation.

Also, I don't like the name "Credit Union". Personally I'm looking for just a bank with reduced involvement in credit and debt that has brought so many countries to their knees!

Related thread:
https://bitcointalk.org/index.php?topic=92665

I couldn't find a credit union that is 100% capitalised. I guess it would have to be 99% just to stay within the definition. For now the only 100% capitalised store for fiat other than cash is a bank in the Cook Islands; no cheap transfers.
97  Bitcoin / Bitcoin Discussion / Semi online wallets on: July 14, 2012, 07:10:37 AM

 I'm stuck with shared internet resources on a boat and I need to pay someone in BTC.

Let's say I have a private key worth in excess of the amount I need to pay. What is the most direct way I can do this?

 A lightweight client like Electrum is an option for me since I do have the ability to run an executable. However, I don't like trusting machines that can run executables without 2 factor authentication like one time use passwords. In addition, it would be nice to be prepared for the time when running .exe's is not possible.

I also don't trust fully online hosted wallets now after MyBitcoin, MtGox and the others.

 I think there's a case for being able to store part of a wallet locally, and/or with one time passwords, and part remotely.

This can be done with a little customised hacking and the paper based javascript wallet system but it's clunky for this application. The main problem is that even if you prepare a load of private keys on a secure connection you then can't divide those amounts offline or online in a secure way without that trusted computer.
98  Bitcoin / Bitcoin Discussion / Best recommendation for Bitcoin balance for a very IT illiterate friend? on: July 05, 2012, 10:29:09 PM

 I have a very good friend in a foreign continent who I'd like to help send me BTC. I know how they can purchase BTC locally.

However, they have no clue regarding security. They're just not very computer literate and scamming in their country is widespread.

 What is the best and most direct way for them to hold BTC bought at say, Intersango?

 Originally I would have recommended the BitcoinSpinner Android client but they have a Blackberry.
Last year I might have recommended various websites but now after the problems at various places I don't fancy that.

 They would (should) be using it for small amounts but even so I wouldn't want them to mess up and that to effect our friendship after I've recommended the system to them.


 I guess what I could do is bypass them holding the Bitcoins altogether and get the place they are purchasing from to send direct to me... but it seems like a cop-out
99  Bitcoin / Bitcoin Discussion / Most decentralised exchange method to build reputation at? on: June 30, 2012, 11:29:41 AM
 I have some dollars in cash in the UK I'd like to exchange.

I could try getting up to speed at #bitcoin-otc but I wondered if there's anything more resilient?

 As far as I can tell Dark Exchange isn't in much use yet and doesn't look very polished yet either to me. I can't see any offers when I search. Does this mean that the i2p backend isn't connecting properly? I wish there was something to let me know if everything is connected or not.

Internet via satellite phone
For many years [when? ]satellite phones have been able to connect to the
internet. Bandwidth varies from about 2400 bit/s for Iridium network
satellites and ACeS based phones to 15 kbit/s upstream and 60 kbit/s
downstream for Thuraya handsets. Globalstar also provides internet access
at 9600 bit/s—like Iridium and ACeS a dial-up connection is required and is
billed per minute, however both Globalstar and Iridium are planning to
launch new satellites offering always-on data services at higher rates. With
Thuraya phones the 9,600 bit/s dial-up connection is also possible, the 60
kbit/s service is always-on and the user is billed for data transferred (about
$5 per megabyte ). The phones can be connected to a laptop or other
computer using a USB or RS-232 interface. Due to the low bandwidths
involved it is extremely slow to browse the web with such a connection, but
useful for sending email, Secure Shell data and using other low-bandwidth
protocols. Since satellite phones tend to have omnidirectional antennas no
alignment is required as long as there is a line of sight between the phone
and the satellite.

Anyone have experience of this?

Also, is there a way to get satellite radio in Europe and south America without a subscription? And can a sat phone be used to get sat radio... for that matter what is the most hackable sat receiver? A net book and gnu radio I suppose?

I work at sea, recently on a boat with no communications or radio to the outside world. Thinking of getting a portable sat radio.

Surprised there's not more phone to pups available via btc...
