Exploring the exciting new world of crypto economic dApp, different possibilities and design factors.

1. Intro to Crypto Economic dApp

… a crypto economy based distributed
application, with support from its human
participants, so powerful that it
displaces a traditional company
(remember Napster nearly killed music industry?)

• Seigniorage -> Dev
• Capital gain -> Dev/Token Holders
• Rewards -> Token holders
minority … majority
Limit & Control
majority … majority
Open involvement

• BitShares X: BTSX burnt upon each txn
• TruthCoin - 2 classes:!
• CashCoin: Store of value
• VoterCoin: Paid for 1/2 all txn fees (in
CashCoin)

biz model

13. Koinify: App Store for dApp!
• High quality & vetted dApp
