No "connection reset", just the page taking forever to load, with GAE or VPN on the page loads instantly. Can any other Chinese user confirm? I have asked several people to run the test and they return the same results.

Wow, that would be bad news!

842  Bitcoin / Armory / Re: Connect to non-local bitcoind? on: December 02, 2013, 09:41:28 AM
It's ridiculous to have 3 sets of the same 7Gb data connected to other peers through a single IP address... my home ADSL line.
It is not ridiculous for me to have another full copy at work, that being on an entirely different IP.

Electrum isn't quite what I'm looking for either, as that connects to public servers. I do want to run 'A' Full node. A cursory look doesn't show me how to create my own private electrum server, though I'm sure it's possible.

Maybe when Armory handles the full node itself, it could also act as a server to other Armory clients.

..as we are all happily necro'ing anyway:
The solution might be to setup your own Electrum server. Then connect all local Electrum clients to that one.

For everyone not liking the dublicate data: every single additional (full) node helps the network. That's how I see it, and leave my bitcoind running all the time.

843  Bitcoin / Armory / Re: The perfect offline printer... on: December 02, 2013, 09:30:29 AM
Well, just like "correct horse battery staple" is a burnt passphrase now, it has its own interesting implications to have two pages of people writing about which exact printer they'll use, where they buy it, and to announce to print unencrypted paperwallets with Bitcoins on them. Long time "Hero members" all over the place. Those with the highest desire to really secure those coins.
Just sayin'!
:-P

Seriously, there were more complicated attacks in the past than that "hey, let's break into their warehouse and put that bug into all of those printers!". Or intercept all shippments.
Ah, screw that, they'll simply find out who we are and use rubberhose decryptography. Meh.

844  Bitcoin / Armory / Re: Write-only encrypted filesystem for transaction transportation on: December 02, 2013, 09:20:49 AM
Wait, what's a "write only" fs? Never heard of that. Probably something like encrypting something with the public key of someone else, where even the sender can't decrypt/read the message afterwards?

Of what use it that here? The infected online computer has to have write access, and the secure to-be-infected offline computer needs read access (for the first part of the signing). With that, the malware will be able to reach the offline computer no matter what. The question is to prevent it from executing on the offline machine. After that, with both machines infected, all is lost anyway.

I may be missing something here?

845  Bitcoin / Armory / Re: Does the Armory wallet format encrypt or protect the chain code? on: December 02, 2013, 08:35:50 AM
As far as I know all wallet app have this shortcoming.  It's not easy to overcome... unless you scan the blockchain on every load Smiley  Because even if you encrypt the watching-only wallet, any data you save between loads can be used to identify what money is in your wallet. 

It's not *exactly* the same. With an encrypted wallet, noone can see the balance when obtaining an encrypted backup. With unencrypted public data in the wallet, this is possible (without access to the Armory computer).

846  Bitcoin / Armory / Re: Does watch-only wallet have a Master Public Key you should keep safe? on: December 02, 2013, 08:28:59 AM
You should always assume that revealing a private key from a deterministic wallet will reveal all siblings.   In Armory wallets, if private key x is revealed with the chaincode, all private keys >= X+1 are revealed.

But I don't spend much time worrying about this.  We do not support or claim to support any use cases where private keys are intentionally revealed.  And if your wallet is unintentionally compromised, they will all be revealed anyway. 

Yes, normally that's not an issue.
For me, however, this would turn out to be a problem:

I hold a small Bitcoin sum for a family member (that's what happens when you talk about Bitcoin all the time, eh?). I gave that person a paperwallet with the private key of where the funds are. I have a copy of that address to do things with the funds when asked.
I used an address in my regular wallet, with other funds inside too.

So, now I have the situation that I intentionally gave away a privatekey to a wallet with more funds than on that key. No matter if or if not I trust that family member, anyone able to obtail that paper wallet endangers my whole wallet.

I guess there's no way around that. I can't have both "independent addresses without a chaincode" and a "one seed backs up everything" at the same time. So I need to fall back to an individual wallet for that person, or stick with a single address. Both would make two backups necessary, one for my regular wallet, one for that person's funds.

847  Bitcoin / Armory / BIP32 wallets and Armorys implementation on: December 02, 2013, 08:16:16 AM
Dear Alan, Goatpig, devs and all,

I have a general wallet question which is partly about BIP32, and partly how Armory will implement it.

1) As I understand it, a seed creates a tree, where each branch itself may form a new branch or whole tree, so to speak. With that, will Armory allow to create multiple "wallets" from one single seed?
Right now I use several wallets, for bookkeeping and not mixing up inputs/outputs of different categories. So it would be important that change addresses and inputs only mix within one "wallet" or "wallettree" or whatever it would be called.

With security in mind:
2) From knowing the "public key seed" (or similar) and one single private key, all private keys may be reconstructed. I guess from the "public key seed" and one public address all public addresses may be reconstructed as well then.
Is there anything I have to take care of in reality? As long as I only use regular Armory functions (sending and receiving) and don't export stuff and don't share my wallet file, nothing evil should happen? Is there anything to extract from the wallet file without knowing the encryption password?
3) I.e., is the "public key seed" encrypted too?

And, finally:
4) In case I can haz several "wallets" in one file, from one seed: Can I have several, different passwords for each "wallet"?

To make sense of all this:
Imagine I now have three wallets. One is my unencrypted playmoney, one is my regular funds, one is my long-term savings (with watch-only wallet), one is funds I manage for mom and grandpa. I don't want to lose all of those in case a keylogger steals my one password. I don't want my long-term savings on my online computer altogether.
Will I be able to have all this from one seed, with the new wallet format?

This would be a huge selling point for me, and differentiate Armory even more as a pro wallet, focusing on security and advanced features.

I know there are some people following this thread who speak German.   I got a guy who has a lot of money stuck in Armory, and his written English is very poor.   I do not understand his situation.  Anyone knowledgeable about Armory willing to help him, or at least help translate?  I'll split any donations received with you (which may be 0 BTC, but sometimes people like this tip generously).

Let me know if you can help.  Even if you just speak german but don't know much about Armory, you can just act as a middle-man translator for our emails. 


I hope this is resolved by now? If not, native German speaker here, using Armory for a good while (on linux).

Now that's the real amazing news here. No assasination, no (real, mind you) mob formed, no bouty, nothing ever happened. Except, embarrasingly, the government who stepped in.
I said before that I would pay a percentage of any retrieved coins.

With Ian, hmm.. I saw no hard evidence that he did something evil, instead of a simple "did something stupid".
Being stupid is one thing, refusing to help is another. As for evidence: I started to get suspicious when I noticed that coins I sent to Ian were moved in July this year. And from the history of that address, it seems like it was one of Ian's pooling addresses.

I wonder if there's enough left in the community to form a mob? I doubt it, somehow..
With investors spread all over the world, there's not much of a chance for a real mob. That's why I think a bounty might work better.

Well, there's a huge difference between a bounty, a percentage of the returns and a plain fund which pays regardless of the outcome..
With the recent exchange rate, even a few Bitcoins should go a long way though. I'm in, just to see some justice done.

He's been acting very fishy ever since Pirate defaulted and tried to hide every detail of his passthrough. From what I know, he also refused to work together with the officials (SEC). So I'm not sure anymore if it really was a passthrough at all.
I wonder if anybody living in Australia would be willing to act on behalf on Ian's investors and face him to talk about all this (and maybe even file a lawsuit). Ian seems to have ignored a few withdrawal requests before everything blew up. Considering the current BTC value, a bounty from those investors would most likely equal tens of thousands of dollars.


Now that's the real amazing news here. No assasination, no (real, mind you) mob formed, no bouty, nothing ever happened. Except, embarrasingly, the government who stepped in.

But then, now it's kind of pointless, at least with Trendon, as the government takes care now.

Guys, don't use market orders! Check the rates on at least two external charts (bitcoincharts, bitcoinaverage, bitcoinwisdom, bitcoinity) and assume the rate is what most charts agree to. Then use a limit order slightly above what you expect to be the rate you exchange for. If it doesn't go through (completely), cancel it and check what side went wrong.
These days are much more of a mess than in April. Now we have non-responding exchanges, offline APIs, lag everywhere, disconnected connections, empty wallets and contradicting stuff everywhere. The old good weather tactics won't cut it here!

Yay, I'm very happy to have you back here, Chris!
I'm sorry to learn some of us were right - you wouldn't go missing if not for something dramatical and lifethreatening.
So glad to hear you are still standing.

Well, I can't be mad at you - still, a one-liner "Had accident, am alive, will be back in some months" would have helped us a lot here. I think I can speak for many here when I say "nevermind the financial mess, we'll figure this out at some point".

I fully agree with Dave: You owe me money. I want you to pay it back by being, staying a part of this community. I mean it, I already started to form a mob to find you! :-)
No, in all seriousnes: If you would agree to such a delegating superviser-position, you would be, stay to be one of the tremdemous assets and contributors to this community. I'm not involved on a deep technical level here, but I had the impression that there are enough people here willing to help, waiting to be delegated! :-)

Again: I am happy to hear from you. Happy to learn you are not smashed to pieces. Happy to have you back.
Welcome home.

859  Local / Deutsch (German) / Re: Ich habe 650€ Falschgeld bekommen (localbitcoins) on: November 20, 2013, 11:27:27 PM
Klar. Nur, dass UV und Marker das gleiche Merkmal testen: Baumwollpapier.

UV Lampen testen fluoreszierende Farben und nicht (!) das Papier des Geldscheins auf seine chemische Zusammensetzung.

Und die Tinten: 99% aller UV-Lampen-"Profis" haben eine 1 Euro 405nm Lampe. Da leuchtet die hälfte der Tinte erst gar nicht.

Nicht ganz.
Geldscheine haben 1) in drei Wellenlängenbereichen fluoreszierende Drucke und Fussel, und 2) ein bis in den UV-C Bereich nicht fluoreszierendes "Papier" aus Baumwolle. Das einzige nicht-fluoreszierende Papier, das der Durchschnittsmensch jemals in der Hand hielt, ist ungebleichtes Zeitungspapier, Geldnoten und Klopapier (welch Ironie). Dabei geht es nicht um die Zusammensetzung, sondern um optische Aufheller. Und die sind nun mal in jedem regulären Papier drinnen, damit das Papier schön weiß scheint.

Günstige UV Lampen mit 250-350nm reichen aus, wenn der Geldschein im Prüfungsbereich, z.B. mit der Hand, verdunkelt wird.

(Siehe: http://de.wikipedia.org/wiki/Sicherheitsmerkmale_von_Banknoten)

Die alten 365nm "Typ Schwarzlichtröhre" Geldscheinprüfer waren nicht verkehrt. Sollte tatsächlich jemand eine 254nm UV-C "Typ Forensik/Briefmarkensammler" Leuchte benutzen, wird er sich langfristig, bei häufiger Benutzung die Augen verblitzen und Hautkrebs auf der Handinnenseite erzeugen.
Das Übliche, was es heute für nen Euro gibt, hat eine 405nm violette "UV" LED. Da leuchtet nüscht an Sicherheitsmerkmalen. Vermutlich kann man die obengenannte Papier-Fluoreszenz sogar ganz plump überdrucken.


Andersrum:
Die zwei verbreiteten, weil billigen käuflichen Hilfmittel, sind UV, "UV" und Stärkemarker. Jedes einzelne Sicherheitsmerkmal lässt sich fälschen, bei zu vielen Merkmalen wirds aber schnell unprofitabel. Also werden die Gauner doch vermehrt genau diese beiden Merkmale fälschen, oder? Und UV und Stärke ist die gleiche Adresse, nämlich die Eigenschaften des Trägermaterials.

Irgendwie glaube ich nicht, dass es auch nur eine Blüte im Umlauf gibt, die dieses fühlbare Riffelmuster nachahmt. Hab ich vorher noch nie gehört, ist mir nie aufgefallen, wird von automatischen Prüfern vermutlich nicht ausgewertet, lohnt sich also nicht.


Keine Ahnung was die Diskussion soll. Ich vermute mal wir sind uns alle eigentlich ziemlich einig.
