Thank you, mate! And I'm feeling with you about your lost coins!
Thanks, it came really by surprise, and there I was believing I was secure... Well it goes to show that understanding something does not protect you from stupid mistakes.

Anyway, sorry to have caused such an uproar, I'm just trying to improve the network, but if you still feel the need to block me I'm using the user agent string "/Snoopy:0.1/ETH Zurich/PlanetLab/"

Sorry about that mate. The Paper is from another group (System Security) in the University, I'm in Distributed Computing.
As far as I can tell we don't have any relevant computational power working on Bitcoin, I'm just relaying the blocks faster than others in the network.

Before any further steps to investigate the transactions, you have to prove that you owned the stolen funds.
Well that shouldn't be too hard, I can sign a message with the private key belonging to one of the addresses. But I don't see that doing any good.

I'm not the only one working with such large nodes btw. There seems to be someone from the university of Munich that is doing something similar:
I wonder what they are doing :-)
25  Bitcoin / Bitcoin Discussion / Re: I've just been robbed :-( on: September 28, 2012, 08:12:50 PM
You're pretty much screwed. :\
Yep, that much I knew already.
26  Bitcoin / Bitcoin Discussion / Re: Is Bitcoin currently under attack? on: September 28, 2012, 08:11:18 PM
Well I was wondering how long it would take for people to notice. It's me Cheesy

And no I am not putting lots of hashing power to the network, notice that it just says "relayed by" and not "mined by". I'm performing some measurements, paper is due in a few weeks.

thank you! due your work I came under attack of some moderators and some pool operators (which I really like!)
Hm? What do you mean?

I can't give you the exact details of what I'm doing until it gets published. I can tell you that I participate in the network as any other node does, I'm just a very big node (5'000 connections open), and am thus considered a Hub in Blockchain.info's vocabulary Cheesy

Well, just to prove that even long time members are not secure from being stupid. My wallet has just been cleared out:


At first I thought maybe it's just an old transaction that has only now been submitted, but I can't find any wallet of mine that owns those keys.

I had my wallet encrypted, but this was apparently an old backup of my wallet that I must have stored somewhere.

Any tips on what to do next? I'm still a bit fuzzy about the details. Can we blacklist those funds somehow?

What exactly is included in the sale? Is it only the domain or does it include the scripts used to scrape the pools and exchanges?
30  Bitcoin / Pools / p2pool - Decentralized, Absolutely DoS-Proof, Pool Hopping-Proof Pool [archival] on: January 23, 2012, 04:26:24 PM
Hi guys, i have small problem. When im trying to see some stats at http://127.0.0.1:9332/graphs im getting error 404 - No Such Resource

Halp!
Does it say anything else or just a 404 page. I had the same problem but I solved it easily by installing python-rrdtool and restarting the p2pool daemon.
31  Bitcoin / Development & Technical Discussion / Re: Should a GPU-based miner be integrated in standard client? on: December 05, 2011, 02:55:19 PM
No, the client get's bloated for the benefit of a minority that will use specialized software anyway.

I'm wondering how you decide when a direction turn is taken. Do you take a fixed length interval and use a weighted average and compare it to the previous low/high?
33  Local / Deutsch (German) / Re: Vorschläge für einige kleine Tools on: September 22, 2011, 12:23:32 PM
Hi Kai,

kannst du bitte den generator abwandeln dass er Bitcoin Standard URIs auspuckt anstatt nur die Adresse?
https://en.bitcoin.it/wiki/URI_Scheme
Is einfach besser wenn wir den standard von anfang bis ende durchziehen Cheesy

LG,

34  Bitcoin / Bitcoin Discussion / Re: Google wallet.. good for bitcoin? on: September 20, 2011, 11:20:17 AM
Google Wallet is good I'd say as it increases the trust in technologies like NFC and electronic payments over the counter. But since it relies on traditional currencies and is completely centralized it leaves room for Bitcoin to evolve. I just hope not too many people will abandon Bitcoin in favor of Google Wallet.
35  Bitcoin / Mining software (miners) / Re: Flexible mining proxy on: September 08, 2011, 09:16:19 AM
The proxy is quite good AFAIK, I have a consistent rejection rate of ~1%, but that's to be expected.

37  Bitcoin / Hardware / Re: Will fund ASIC board for mining community. Need Hardware devs. on: July 15, 2011, 11:10:06 AM
I would invest if A) it were feasible
                        B) the numbers were more concrete e.g cost defined
Same here, funds are at the ready :-)
38  Bitcoin / Bitcoin Discussion / Re: MtGox SEPA Transfers on: July 12, 2011, 11:53:14 AM
Uh, that's good news, I'd love a Swiss Bank since it allows both SEPA and Swiss Bank withdrawals :-)
39  Bitcoin / Development & Technical Discussion / Re: Bitcoin overlay network on: July 08, 2011, 12:37:57 PM
I proposed structuring as a Skip-list or hypercube, and instead of broadcasting to all I'd love to have a broadcast to prefix only. A hypercube of dynamic degree, multiple nodes at each edge, taking care of a given prefix. Miners would regularly fetch all transactions and include them into blocks. It would reduce broadcasts and scale better.

The idea was shot down pretty early with the usual arguments: too hard, breaks too much,...
But I still think it should be considered :-)
