I'd like to see a P2P app store on the same kind of system as cryptocurrency. Like torrents meets P2P consensus for file verification, with weights for trusted sources.

Verification - Civic/KYC solutions?
Prevent cracked apps - some game theory/staking mechanism that makes you lose if you don't play the official version
