In Episode #2 of DigiByte and Friends, I have Forrest (Hashoshi4) on to talk about dApps.  We talk about building on Ethereum, DigiAssets for DigiByte, what can / shouldn't be a dApp, challenges, costs, and building for the future.  You should definitely check his YouTube channel out, he does a ton of great educational and informative content that's well worth giving him a subscribe: https://www.youtube.com/c/Hashoshi4?sub_confirmation=1
