Though I think that the fundamental question should be: = how many nodes do we really need? Obviously more is better, but it's diffic= ult to say how concerned we should be without more information. I posted my= thoughts last month: http://coinchomp.com/2014/03/19/bitcoin-nodes-many-en= ough/ In my opinion, the number of full nodes doesn't matter (as long as it's enough to satisfy demand by other nodes). What matters is how hard it is to run one. If someone is interesting in verifying that nobody is cheating on the network, can they, and can they without significant investment? Whether they actually will depends also no how interesting the currency and its digital transfers are. > On 04/07/2014 07:34 AM, Mike Hearn wrote: >> At the start of February we had 10,000 bitcoin nodes.

It's seeing around 6000 "well reachable nodes" currently, which is the highest number I've ever seen (though it's been around 6000 for quite a while now). --=20 Pieter
