Single Player-Ready Dapps by Wayne Chang

Imagine if the restaurant review site Yelp was truly decentralized, that you had your single player-ready instance that was just for you, and you felt free to share your most private thinking on how you felt about a dining experience. You could then turn on multiplayer, and share just the parts you want to your organization's or family's instance. Perhaps your organization belongs to a superset of organizations, such as a coalition--you could share to there too with the right settings. The point is that you are the data owner, and the buck stops with you, but you're also free to federate into larger fractals to your heart's content. This is what a Single Player-Ready Dapp is. Social media sites could work the same way, allowing you to export your entire social media graph seamlessly. Then you can use the blockchain to govern these federations and access financial services such as payments, all without intermediaries. All this is possible very soon, and will be convenient for dapps to become "single player-ready". I will present an end-to-end architecture that uses Sign-In with Ethereum and other extensions to demonstrate how you can build one of these as a concrete implementation. Wayne Chang
