thanks

Any update on this?  I'm interested in Bitcoin developments in CR. Thanks.

Alan Reiner of BitcoinArmory (fantastic program btw!) has an 'Offline signing key'

http://pgp.mit.edu:11371/pks/lookup?op=vindex&search=0x4AB16AEA98832223

I am inferring that this is a PGP private key on a 'cold storage' computer, with a different passphrase to his main 'hot' computer private key(s), that protects his electronic signature against keyloggers by using an air-gap, just like Armory does for bitcoins. Therefore a sig of a hash of a binary (eg Armory) is very difficult to impersonate with a malware binary.

However, I think that the above can only achieved by having a separate 'cold signing' keypair (but I'm not sure, hence this post).  I'm thinking this because:

• Alan's key has only have one subkey within the public key he distributes (FF52507FDE6B2D74).  This means I can only validate against one key, which is presumably the same one used for receiving emails etc, ie on his main 'hot' computer...
• Even if his cold-signing subkey was included, when I do gpg --verify filename, it only shows the main keyid, not the subkey, for example "gpg: Signature made Wed 25 Dec 17:06:03 2013 GMT using RSA key ID 98832223". Thus if the hot key's passphrase was compromised, then a hot-signed malware would still be indistinguishable from the cold-signed genuine binary.

I want to have a separate passphrase that I only use for signing on an air-gapped computer. Am I right in my thinking?  Or am I missing something? 

I'm doing this on OSX using gpg (GnuPG/MacGPG2) 2.0.22 by the way.

Thanks for tweet Benson. I'm Marco, CEO of MatrixVision.
We are a Bitcoin-side compliance service.  What that means is that for companies that need compliance (eg exchanges, investment funds, payment processors, bitcoin ATMs etc) - a) they already have services to monitor FIAT-side transactions, often indirectly via their bank or PSP and b) we perform an analagous service for Bitcoin-side transactions.

We're not payment processors nor investigators. We monitor transaction behaviour, flag potentially susupicious transactions, and the exchange, ATM etc takes investigations from there. 'potentially suspicious' means preventing the proceeds of crime from flowing back into the banking system. That is, preventing money-laundering - it's not about detecting crime itself but having controls for AML (anti-money laundering) so that the exchange/ATM/bitcoin business etc is allowed to operate.  I wrote a post about this on reddit.

Yes to suitability for India - we're worldwide with the service tailored to the regulatory requirements of each jurisdiction.

Hope that helps

Grau, where is the schema now located, can't find it via that link? Thanks.

I would be interested in merged mining?

Salut,
Mois aussi aujour d'hui trouvé ce chose, et cherché pour des nouvelle ou interprétation. 

Je ne sais pas bien mais peut-être pour bitcoin-central ça devient qu'ils ne peuvent pas seulement utilisier un rélation bancaire mais ils faux aussi s'appliquer de devenir un banque??

Yep, I'm confirmed, bar raids sounds great.  Arriving San Jose sometime Thursday avo. 

Staying in downtown San Francisco from Monday to Wednesday evening - anyone in SF want to meet up?

Yep, just booked it 

I think it means that if you're selling at face value, VAT is due when someone buys a good/service with their bitcoin (ie that vendor must account for VAT not you).  But because you have 10% markup over MtGox (arguably 'face value'), presumably you're due for VAT on that 10% markup.  Just my reading, DYOR of course.

btw, quick beer-mat calculations - with VAT threshold at 79k, let's say at 60k you started worrying about VAT...2.5% means trade volume of £2.4m, 3.5% means £1.7m. So have you traded somewhere in between, approx ~£2m of bitcoin in a month, or are my figures out of whack?

I got mine back today, 

People have started getting their BTC back.  Cool stuff from bitcoin-central.
Thanks for replies.

bump!

Newbie so unable to reply to this Re: Bitcoin-Central.net "We have been compromised" thread:
https://bitcointalk.org/index.php?topic=186609.0
I can understand time taken from manually processing from a cold wallet, but some guys have been waiting 6 days:

I'm not sure if I should trust entering my password on https://failover.bitcoin-central.net/?
Has anyone got their BTC back? 

Understandable - but definitely tedious. Have been reading posts for months but never needed to make my own post until now, and can't. hohum.
