on the topic of pools, hashrate, and security of the blockchain, docs.guldencoin.com lists the following pools under 'the coin' -> 'mining':

http://nlg.criptoe.com
https://nlg.hardcoreminers.com
http://gulden.p2p.0x0a.nl:27100
http://pool.mycryptoco.in
http://dutchpool.org:8000
http://dutchpool.org:27100/static

I tried to go to each one and get the current hashrate.. got the following..

HASH:   url
---------------------------
025MH/s:  http://nlg.criptoe.com (invalid url? criptoe.com works)
234MH/s:  https://nlg.hardcoreminers.com
000MH/s:  http://gulden.p2p.0x0a.nl:27100 (stratum still alive?)
000MH/s:  http://pool.mycryptoco.in
013MH/s:  http://dutchpool.org:8000 (invalid url? dutchpool.org works)
???MH/s:  http://dutchpool.org:27100/static (invalid url? different than above?)

272MH/s: total hash from above

According to seeds.guldencoin.com, the net hash rate is over 800 MH/s.  so I assume the rest of the hashing power is coming from individuals or groups running private pools?  I remember a while back someone ran some queries against the blockchain to see what addresses the newly generated coins were going to.  

PS: maybe we need to clean up this info on docs.guldencoin.com?  I think the urls on post 1 of this ANN is more accurate.

PPS: last thing - the navigation links on guldencoin.com are in dutch.. IE: Overzicht, Versturen on https://guldencoin.com/receive didn't know if that was intentional to subliminally teach us dutch or an oversight.
