Yes, you can do that. We’re doing something similar with Zombie Battleground cards (but as ERC721x tokens). Users open their packs on PlasmaChain and that’s where they receive their cards, but they have the option to send them to Ethereum Mainnet.
We wrote about some of the benefits of running the game on the blockchain here and here. But basically, it makes the game’s fairness auditable, users can code and upload their own server-side game modules making game development a community driven project (embracing the modding community), the game state is forkable if players don’t like the changes…
Initially, the incentive for developers will simply be that there is a high demand for these type of games from consumers: There is a hungry market and very little supply.
It’s unlikely that large game developers will immediately jump on this trend, which provides a great opportunity for small to mid-sized game developers to…
It’s not on the blockchain. I’m assuming that’s the type of data that `ERC721Metadata` was originally going to be used for, but they decided against using it in the end.
So it’s probably just stored on their web server. I haven’t actually bought any CryptoKitties or tried changing their names, so I’m not sure how they’re…
For those just getting started, you may want to check out https://ethfiddle.com/ — we built it as a simpler, more beginner-friendly alternative to Remix for playing around with Solidity in the browser. (And sharing your code snippets).
Thanks for the kind words Chris!
We’re planning to open source the lessons and the eventual code of the CryptoZombies game we build, yes. Possibly open source the lesson design as well so other people can create their own lessons in the same format, but we have a lot of other things we’re working on at the moment and that probably wouldn’t be until later.
Great writeup! I’m a big fan of Jimmy Song from his articles. He has a knack for taking complex topics and breaking them down in plain English to be easily understandable, and agreed he’s one of the more objective and trustworthy voices in the space.
