2701  Other / Off-topic / Re: Can the Hashes from block generation be useful? on: April 26, 2011, 12:49:38 PM
can they for example be used in cryptographic research, or anything else useful?

or are they just completely useless?

Bitcoins themselves have value since they can be used to slow spammers down.

http://en.wikipedia.org/wiki/Proof-of-work_system
i did understand the whole proof-of-work system.

but can the hash-to-blockdata mapping be used for something else.
i mean all thees 0's in the beginning of the hash, can they be used for something? can all the hash-block pairs be used for not just generating btc? it is not everyday a cryptografer haves a 960.36 ghash/s network, which is generating a lot of 0's

Spelling: "Assest" should presumably be "Assets".

Sent 5 BTC. I would love btcex support since they charge no fees on trades.  I'll offer 5 BTC for that as well.
Thanks Cheesy

Looking at the code... it does not do much more then displaying an interface, right?

it does absolutly nothing more then displaying the gui.

From https://github.com/bitcoin/bitcoin/pull/183 :
Quote from: gavinandresen
Can you start a forum thread about this? There was some concern about possible attacks revealing private keys if the attacker can send arbitrary data to be signed.

im not sure about ECDSA, but rsa have a blind signing flaw: http://en.wikipedia.org/wiki/Blind_signature#Dangers_of_blind_signing
also if an attaker is able to sign just something, he/she could sign a transaction that send him/her all your coins... Sad

i think it's a dangerous but useful feature, but i would not use it.

im glad seeing people using it Smiley

if you use it and want to see more of things like this from me, please feel free to donate: 1EJXbMi5CjHeNmUQNpZgg72HWzEMX8tVja

I was thinking that I have a server that is running say... a http service on port 9090, so I would give you an ip and port 123.122.122.1:9090 , you then have your server forward traffic from a tor address to my server.

Easy, right?

Very Easy. Smiley ... but what if your have a dynamic ip... say 123.122.122.1 today 123.122.122.67 tomorrow, many people have that.
then you would need to update it every day, or you people could not access your site. Sad
you could also make some kind of auto updater, but i don't think people will use it, they would just run their own tor server
2709  Bitcoin / Project Development / Re: Python bindings for the Mt. Gox trading API (v0.01) on: April 24, 2011, 12:58:04 PM
This is great. Thanks. 1btc sent.
thanks Cheesy
2710  Bitcoin / Project Development / Re: Tor Hosting? on: April 24, 2011, 12:46:48 PM
I think what you should offer is Tor forwarding(especially with such limited resources), that is have it set up so that your server has multiple Tor (or i2p) addresses, and then forwards the traffic from those addresses over a https connection/tunnel to another server(which only you and your client know, don't keep any traffic records).

This will allow others to get onto Tor and run services from there without the hastle of having to run their own node software(which is a real pain), it also means that you will probably be able to get the most out of what little resources you have.

You can certainly do this with i2p, I'm not sure about Tor, is it possible to have multiple .onion addresses for a single Tor node?

At least, this is definetly a service that I want (and I'm willing to pay for), I think others would really want this too and you could easily charge a modest fee. Help people register a .i2p address that goes to the server too, would be great.

This is an area that my syndicate will be moving into in the future (after a few other things are taken care of), safe, secure hosting withing cypherspace.
the problem with only providing tor forwarding, it that its at least as difficult as setting up tor yourself...
what i am offering is that you get a simple solution where you get a normal ip address(eg. 10.1.0.50) on a private subnet(eg. 10.1.0.0/16).
you run your service as normal, and then having a little nice web interface where you map random_tor_address.onion:port to 10.1.0.50:port. simple, clean and easy.
of course when i get users/money enough i will buy a new bigger and better server andmuch more bandwidth. Cheesy
2711  Bitcoin / Project Development / Tor Hosting? on: April 24, 2011, 11:52:14 AM
hi!
would you use a small(128mbram, 2g hd, 10kb/s) tor uml-based hosting. (what i can offer for now, will be bigger if the interest rises)
all your traffic will get anonymized through tor, and you could get as many tor address as you want. but still you would not be running/setup the tor server, i would run the server and i could(if i wanted to, but i don't) see all your traffic.

for example small prototyping of bitcoin relatet projects?

its not for strong anonymity but ease of use.

if you would how much do you think you would buy it for?
2712  Bitcoin / Bitcoin Technical Support / Re: Temporarily Banned from MtGox... how long? on: April 23, 2011, 08:23:20 PM
Not heard of that yet.

Yes, would like to know more about that.  Were you accessing it to often with a bot or something?

NO ABOUT 5-7 TIMES WITH CAPSLOCK ON.  Sad i can log in now about 24h after... fine again! Smiley
2713  Other / Off-topic / Re: real router and tor? on: April 23, 2011, 06:22:30 PM
I think you're looking for a transparent proxy that routes all traffic through tor.

I've never set something like that up, but I think squid could do that or maybe even iptables alone would pull the trick.

something like that, i researched a little, and found a (buggy and bloated) SOCKS to tap, which is great! just need to hack it together Cheesy
2714  Other / Off-topic / Re: real router and tor? on: April 23, 2011, 06:07:05 PM
What about JanusVM?

You setup JanusVM on 1 computer and create user accounts on it. Then you can create an VPN connection to JanusVM from all your computers. This will ensure that your traffic is routed through tor. Can be used for anything, not just websurfing. Personally I have setup a virtual machine which is running a VPN client to connect to JanusVM. Works great!

Quote
JanusVM is powered by VMware, built on the Linux 2.6.14 kernel, and brings together openVPN, Squid, Privoxy, and Tor, to give you a transparent layer of security and privacy that is compatible with all your TCP based applications. DNS request are also passed through Tor so even your ISP doesn't know what web site you are looking at. All your web traffic is passed through squid and privoxy to filter out unwanted internet junk & prevents your web browser from leaking information about your computer system.One of the core components that make this possible is an awesome piece of software called Tor. Tor is what allows you to re-route your traffic around the internet anonymously. A more detailed explanation of this can be found here.

Features:
* Works with WiFi.
* Support multiple users in a LAN.
* Protects you from most man-in-the-middle attacks.
* Protects you from Javascript, Java, and Flash based side-channel privacy attacks.
* Protects your identity and your true location by masking your IP Address.
* Encrypts and re-routes your DNS request and ALL TCP traffic to ensure strong privacy.
* Strips out most privacy sensitive information your web browser may leak.
* Blocks popups, annoying ads, banners, and other obnoxious Internet junk.
* Very simple setup and operation.
* Works transparently for applications using TCP. (No UDP or ICMP support)

sorry but a quick look, i think its crap. sorry Sad and i also don't want my internet to by filtert...

what exactly are you trying to achieve?

if I understood you correctly, possible solution could be to use virtual machine and use NAT.
i try to achieve to anonymisize anything from my ISP.. i have 5 computers on my home network, so insted of setting tor up on them all, i would just do it on the router, and block very thing else. so all that my ISP sees is tor trafic.
2716  Other / Off-topic / real router and tor? on: April 23, 2011, 03:55:18 PM
hi!
is there an one who knows if there is any software that can act as a real router network router, but route all the traffic through the tor network?
like: tor <-> router <-> normal network
2717  Economy / Economics / Re: is it possible to block the MtGox exchange? on: April 23, 2011, 01:09:16 PM
is it? to lock the prices?

if you had many btc(say 10000btc) and you where buying at 1.35 and selling at 1.4. would you lock the market between 1.35 and 1.4? becuse every time some one bouht some coins, and there was't any asking below 1.4, you would gain some profit and the blocking would be bigger...

it that possible?

As soon as the market would move into one direction (many buying or many selling) the "lock" would overflow and the market would break out of the "lock". The only thing it would do is delay a upward or downward trend.
yes but the longer and bigger the lock are the harder it would be to break it, it's will get bigger over time

Message me your amount/price.  I only work with 100% safe trade methods like escrow.com

Lowest price will get bought.

My experience is that you can get some decent speed with tor these times.
well it was about a half-year time since last a used it, back then i got a max speed of 40kb/s now its 200kb/s. a great improvement! Cheesy

That could be caused by bitcoin:

thats nice! Cheesy going to donate now
