NO! not a good idea! if you will use tor, use the proxy feature.
Im a fan of tor but i don't think you should blend it with bitcoin, its a reason to shut it down.
politicans/lobbysts dont like when people are anonymous, and its give them a another reason to fight us.

i only use tor+bitcoin when im at school because my school blocks many ports, and the simplest way around it is tor.
2642  Bitcoin / Bitcoin Discussion / Re: why the sudden bitcoin interest in Sweden? on: June 02, 2011, 03:52:40 PM
There has been a lot of talk about Bitcoin in the Swedish blogosphere, much due to Rick Falkvinge (founder of the Swedish Pirate Party) proclaiming that he has invested all his savings in bitcoins. (At least that's how I found out about it.) See this link (in English): http://falkvinge.net/2011/05/29/why-im-putting-all-my-savings-into-bitcoin/
he is swedish, but he mostly(only) writes in english, and is a representant for the pirate party in EU. he is known all around EU, it might be why.

Sweden is in front with technology here in Scandinavia. not a surprise for me.
but Finland i have difficult to understand.

hell sweden came with the pirate bay, they have been in front since the '90.

im a danish. i live in Danmark, and has knowledge about this.

Now $10.50   Grin
what are you talking about? its 10.57

have you seen that the demand for bitcoins is high and the supply is very low:

i am not a economic, but it must mean higher prices. Cheesy

I'm relatively new to this, and have no idea how these blocks are constructed, so I fail at "calculate the midstate" and "generate the data", as I have no idea where to get the binary data of the block.

Well, I'll probably look at some miner software later today, I just thought that fpgaminer might have the values handy from his own testing...
i could do it for you for say 10btc.
its very precise and complex work.
and its requirer alot of time, and experienced.
so 10btc is relatively cheap.

I did manage to synthesize a design for an xc5vlx110t-1ff1136 (which I had sitting around anyway) running at 120MH/s in the meantime. I chose to not use JTAG for communication, and implemented a simple RS232 interface instead.

The next step will be getting myself used to how all this mining business works and how to communicate with the mining pools.

Can someone provide me some checking values (256bits midstate, 96bits data, 32bits nonce) which result in a "golden ticket" (hash with the first 32bits being zero), so that I can verify that my design works correctly?
can't you just not make your own, it should not be too hard:
pick a known block.
calculate the midstate.
generate the data.
extract the nonce.
done! Cheesy

i really likes to see when btc shows unexpected up in my Client. makes me happy Cheesy

thanks for the 0.20 btc.

If you just want to fool around, start with this:
http://www.xilinx.com/products/boards-and-kits/AES-S6MB-LX9.htm

It's just $89.
Yeah you can get some cheap FPGA boards no problem. Terasic sells the DE0-Nano board for $79USD, or $59 if you're a student. That's for a 22K LUT device, which is pretty darn good for the price!

I'd respect you if you got 1 MH/s out of it.
You can get 1 MH/s out of it no problem.
can any FPGA work? how small can it be? will this be enogth: http://cgi.ebay.com/EP2C5T144-Altera-CycloneII-FPGA-mini-Development-Board-/270748203437?pt=BI_Electrical_Equipment_Tools&hash=item3f09d9b9ad#ht_1520wt_907
and how high can you clock the boards? without they are catching fire.

it would be nice to have a 1-2Mhash/s board, just for fun.

A Spartan 3E 250K has 5508 logic cells. If I understand correctly, this is not enough for a design that needs 90K LUTs, though I'm still learning about all of this.
I'll try to put my serial design online as well. That fits into 3K or 4K I think, although it's obviously much slower (64 cycles per hash). It's a nice toy for people to play with if they have smaller boards.
well that would be very nice, so all us with no big money could try too Cheesy
2656  Bitcoin / Bitcoin Discussion / Re: why i can't received bitcoins from others on: May 20, 2011, 03:19:28 PM
I creat a new bitcoin address and i find that i can't received from other people.

i have got free bitcoins from 3 different websites and ask a friend to give me some bitcoins.

But I have not received any information on my client .

Is this normal?
had you downloaded the whole blockchain yet?
the number in the bottom should say something around 125320.
if you haven't you client is likely not to have seen the transactions to your address yet.

just wait...
2657  Bitcoin / Hardware / Re: Official Open Source FPGA Bitcoin Miner (Just Released!) on: May 20, 2011, 12:49:01 PM
just a optimision, from a noob:
is it possible in sha256_transform.v to remove the generate loop, and replace it with some sort of pipelining instead, it will from what i can understand make the code smaller, but have a greater delay. and with smaller code you could have more of them on a single board, and a higher clockspeed.

am i talking gibberish, or do i have something right?
its was all from what i could learn from the internet in about 5 hours. Smiley

i just think it would be an improvement
2658  Bitcoin / Development & Technical Discussion / Re: New Attack Vector on: May 17, 2011, 05:44:52 PM
This actually is quite similar to another "corner case" that I've been wondering about.  Consider the following scenario:

User downloads installs bitcoin into a windows virtual machine, the copies the virtual machine to multiple locations.

Each of the virtual machines attempt to engage in transactions (receiving, sending, or even mining and block verification.)

What function is mitigating the collisions between clients, and which client becomes most authorative?  While I see how this could result in issues in transaction confirmation, wouldn't confirmations by those cloned entities result in confirmation corruption?
1. none of them.
2. no.

2660  Bitcoin / Bitcoin Discussion / Re: Still no coins after 68 hours and approx. 1,000 approved hashes? on: May 15, 2011, 02:10:51 PM
I started mining using GUI miner on Thrusday afternoon. It said it was working fine. It had 24.5 Mhashes a second. I went out over the weekend and have just come back on Sunday night and still have no coins. What am I doing wrong?

Cheers, Sean

nothing, but it takes appox. 319 days to mine a block at that rate
