Sr. MemberActivity: 476Merit: 250 I just realized why I need to start mining, so a question for miners March 31, 2013, 06:19:51 PM #1 The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.



The importance of the above quote struck me last night. So I want to throw in my .02 btc of being an honest node and add some hashing power. I'm not worried about spending a few more dollars on electricity than I make in bitcoins because Bitcoin has already treated me so well.



I mined on my laptop back in the day but stopped when it went to GPUs. Now, looking at mining has the same effect on me as the first time I encountered Bitcoin itself. It's confusing for us non-miners. So perhaps an expert or two could help clear up the confusion.



My question: What's the lowest impact, cheapest method of adding 1-2 gigahashes/s to the network? As said, this is just to be an honest node as I'm not worried about profit from mining.



Thanks!

In that case it's not you, but the pool-operator who has to be honest (and you don't really have any control about that).



But to answer your question: the cheapest way in terms of initial investment is probably to grab some used ATI GPUs on ebay, although the energy-cost is quite high for the long term. Another way would be to grab some used FPGA boards, higher initial investment, lower energy-costs. Or just wait a few more months and hope for ASICs to be available/affordable.

And that's about all methods around for everybody. The "being an honest node" argument with just 1-2GH/s is moot, because with such a low hashrate you're probably going to mine on a pool anyways.In that case it's not you, but the pool-operator who has to be honest (and you don't really have any control about that).But to answer your question: the cheapest way in terms of initial investment is probably to grab some used ATI GPUs on ebay, although the energy-cost is quite high for the long term.
