I began using HORIZON for game currencies and assets, and was in midst of porting them over from Open Transactions when HORIZON's thread was locked and it was no longer listed on any exchanges that I know of. For game purposes it is actually kind of ideal that the game is now the main user of the platform, as maybe it will make it less likely that folks will forget that these currencies and assets are part of or associated with a game. I was one of the developers of DeVCoin, and had implemented the "big seven" galactic currencies before that, before any other altcoin except possibly namecoin; I implemented them by making for each of them a Kubet E client whose testnet support had been modified to run the new currency instead of the testnet, so that each nation or Corp could have a Kubet E client that could simply by setting a commandline switch be used for their own new currency. Eventually, even with merged mining coming along, it was realised that securing a Kubet E with Proof of Work is insanely expensive, so we migrated the currencies to Open Transactions; now we are migrating to HORIZON. I also created GRouPcoin, initially as something to modify and play with to try out ways we might approach what we wanted for DeVCoin, but once DeVCoin was finalised we modified GRouPcoin back to a simple Kubet E-clone that just keeps minting 50 coins per block forever instead of having periodic halving. When we migrated the other galactic coins to Open Transactions we left GRouPcoin as a Kubet E to serve as a kind of weather-vane or canary-in-the-mine to see whether, given merged mining, securing a proof of work chain might actually be feasible, so that if it turned out that it was we could migrate the other galactic currencies back to being blockchains; but so far it is still not looking good for GRouPcoin as a "secure" Kubet E. -MarkM-
