Is it possible to search through the blockchain and find signed messages? Can these messages be linked to wallet addresses?

Or is it more like a one-way thing, where you need to know the message and the address before hand, and than you can verify it, like if it is hashed ?

I was just wondering if this could mean anything for bitcoin mining ... ?

BTC are high right now and I even bought myself a decent rig because of this.

But it is of course possible that the BTC comes down. At what price is mining no longer profitable? What are your thoughts on this? Have you concidered this when you started? Looking for some opinions before I go and buy more stuff.

This is how I figure:

• Electricity is free for me, so mining will always be profitable, no matter what the price is.
• I can write the equipment off from the profits from my company and have a bit of a tax-break.
• Having a dozen GPU's rattling around the house is worth the investment all by itself.
• I learned a great deal about Linux thanks to LinuxCoin. -> more than worth it.
• I learned a great deal about economic thanks to all of you -> more than worth it

I've got free electricity for at least another 6 or 7 months and an entire room dedicated to mining.

However, I've spend all I can on hardware ( gotta pay staff, rent and food  )  

Anybody up for a co-op? I was thinking: we share the hardware cost and the profit. I set up the machines, you manage them remotely over our 100/100 fiber network. We have some good old fun. Burn down the house maybe. Things will be sweet.

I cannot make a transaction < 0.01 BTC.

So the lowest amount I can pay is 0.17 USD (at current exchange rate)

So, if we reach 1000/1 USD/BTC by the end of this year, the lowest amount I can pay is 10 USD?

At least with the dollar, I can pay 0.01 USD...

...

Also, I'm an end-user. Dont expect me to understand all these weird error messages ( ? complexity of the transaction ? )

Hi guys,

I know CPU mining is not cost effective with the electricity cost and all that. But I pay a fixed-priced electricity bill and have over 50 systems at my disposale (outside office hours).

I've tried some of these systems the other day, but they all have old on-board video-cards. So GPU mining is a no-go.

I tried running GUIminer an diablo miner, but they both tell me there is no openCL device and just sit there doing nothing.

Is there any miner out there that I can configure to use CPU mining only? All of these systems use Intel CPU's. Both Linux and Windows are fine.

Oh, and of course I want them to Pool in deepbit.
