Globalcoin Request/Addition

[ghost]

Could we add Global coin to the networks.py & bitcoin networks.py of the Rav build. Not sure what will be needed to make this CatmanSPC p2pool object work in your build.

This coin have only 40s block time, so if we take 10s share time 1/4 will be doa all the time. We need 5s share target.
Do we need 24h share chain? 12h would be enough to not get too many "jumpers"
Also target_lookbehind is way too big, when miners win join/leave share diff will not react fast as it should.

So more like this? Also, if my share_period, share_chain or target_lookbehind is different then the other P2Pool nodes wont I get errors if the other nodes have Cartman's settings and not the ones below. I would have to start a new sharechain with these params correct?

Me and Rav3nPL obviously disagree on a few things :)

As you can see at http://xpool.net:8860/ it is not getting 1/4 DOA (1.86% at the moment).
From experience and closely watching large spikes in hash coming and going a spread of 200 is fine.
24 hours allows a larger window for miners to find shares and not be in the dogecoin p2pool situation.

Currently I'm using your settings in Rav's build and it looks to be working fine for Globalcoin. I'll see what the situation is after I receive some coin of course. Should I expect errors by using your settings in Rav's build Cartman?

No, we both build off the latest 13.4 from forrestv
