This document provides an overview of decentralized applications and related concepts such as decentralized autonomous organizations, corporations, and smart contracts. It discusses how blockchain technology can provide a trustable public cloud infrastructure. Different components of decentralized applications and consensus are outlined, including application state, economics, governance and cryptoeconomics. New compensation models for software using crypto tokens are proposed. Examples of existing decentralized applications like Augur and Deckbound are briefly described. The document concludes by recapping distributed tools that can be used to build decentralized applications.

- 7. dApp stack Blockchain Consensus Layer Meta Layer / API model & controller: consensus-critical View model & controller: regular application logic API
- 8. Consensus components • Shared application state: Proof of X • Economics: distribution & incentive • Membership / Access control • Self Governance
- 9. Cryptoeconomics: A design pattern • Encourages open & common protocol • (Native) Crypto Token serves to: • Secure network. Storing / processing data • Incentivize developer as seigniorage • Reward Content/App specific contribution • Gamification • Bootstrapping, Continuous Price discovery
- 10. Software as public goods
- 11. New compensation models … means more public goods • Classic corp models • Product sales (Apple) • Extra service (Redhat) • Asymmetric monetization (Google ads) • Crypto models • Seigniorage -> Dev • Capital gain -> Dev/Token Holders • Rewards -> Token holders Limit & Control Open involvement minority … majority majority … majority
- 12. - Data layer for blockchain: Federated + Auditing nodes - 1 min confirmation time + 10 min pegging to master blockchain - 2-class structure: - Factoid: Mining rewards. Exchangeable. Constant annual token inflation - Entry credit: For recording data.
- 13. Deckbound • First blockchain based trading card game • Colorcoin-like tracking for cards • https://www.youtube.com/watch?v=d_- mxgUNiOM#t=27
- 14. Augur: P2P prediction market • “Google for the future” • Weather insurance, election prediction, enterprise forecast, price discovery, funding public goods • Sidechain + Ethereum • 2-class structure • Stable Coin: Stabilization via Seigniorage shares scheme. • Reputation: Fixed supply. Non-fungible. Use it or lose it. • Reputation allows nodes to vote on decision outcome.
