I've actually thought a bit more about the issue here, and I think it might indeed be possible to use a delay here (as suggested by Bitcoin Co-Op). The idea is that we advance the game state only every N blocks, using all transactions confirmed in the last N blocks (considered to be at the same time). Then even if some miners do not like your transactions, you are fine as long as any one picks it, which should be fine unless a big chunk of the hash rate colludes against your transaction (and assuming the "attacking" miners are not actually in the majority and orphaning blocks just for this purpose). An issue here is that players are incentivised to wait until the last block in the time window, since then they can best react on others moves (but then it is their problem to balance this with transaction confirmation).
Maybe you could nullify the latter problem you've stated here (as well as other problems with blockchain gaming, in general) if we had some way to obscure data in transactions such as moves ordered on the map. Any efforts to implement fog of war could be synergistic, there. Can't see where they're going, then waiting for the last block in the set is useless
Noob help...
I get all the way to seeing the map, go to create a new hunter, enter info, click ok and nothing...
I have 1200 HUC, enough to create a hunter, but never see him appear nor my total go down. Help!
Did you use the all-in-one installer and is your client fully synced with the blockchain and gamestate?
Yes, and yes fully synced on blockchain. Not sure how to see sync on gamestate, but appears to be synced as it goes up a block every so often.
