I was a bit concerned with the rate of development on this coin - it's pretty far behind litecoin and bitcoin, but it doesn't need to be.
http://worldcoin.global has been down for a long time and finding information on the coin is super difficult.
I will be putting some effort into modernizing Worldcoin. To start, I've registered
http://worldcoin.network and I'll be putting links to the repository on the page. (There's no web page yet, and I'm a terrible front end developer).
The second thing I want to do is to merge the WorldcoinGlobal code changes back into the original worldcoin repo on github, and then begin upgrading the wallet.
Stay tuned for great things!
