regarding las tpost by mm and bitcoin co-op
i may have misunderstood some -but you could jsut do this now, that's what wiggi has shown?
and without any script stuff or changing anything. as long as you get people to use your own calculated gamestate (like wiggis gem client) you could have all the information you need.
every player has an address, and each player in time can have their address shown using name_history (in case someone else creates a toon with the same name)
maybe i'm not understanding completely though ..
no, you can't without node consensus and non-patched daemon would not have had features that patched daemon would have.
And the worst thing is that you can't even change game rules by script without hard forking. Scripts allow you to do anythink because nodes already have all they need to validate scripts and execute them.
I don't know if i explained me bad or what, but you can't even get close to what i mean actually
edit
just read some more and i think i understand.
i think your ideal solution was just an example (gems)..
if talking about gems or anything calculated by gamestate then you can just use modified client like wiggi. you can have a complete new currency in the gamestate if you want. as long as people are using your modified daemon you can add diamonds to the map and it doesnt matter if i dont have the client. same as wiģgis gems. as long as it's not affecting the mechanics of the original game.
if you mean game mechanics changes...maybe you are then will need consensus by all nodes
voting is difficult to do as the rich will always get what they want due to how most cryptos work. maybe if voting is expensive and the coins become part of the fund?
