I'm very interested in the SMT concept as a business model, for a blockchain with a specific application (in this case social forums and discussion) to provide its application for others to iterate new applications and interest-based communities onto.

I'm considering this model for our own network, which connects people to ecovillages and off-grid living schools around the world, but could just as well be used to create and link networks of hacker spaces and digital nomad paradises, coliving, cannabis B&Bs, and other decentralized communities linked by a shared interest.

Is anyone familiar with other blockchain business models with specific applications that get open-sourced for other entrepreneurs to launch similar applications on top of? Sharetribe is the closest thing that comes to mind in Capitalism 2.0 (although I wouldn't be surprised if they tokenize soon!).
