I did some more research about decentralized shared economies. I came across Origin Protocol (https://www.originprotocol.com/), which provides a library (set of tools for programmers) to make it easy to create and manage listings on the Ethereum blockchain. Existing businesses or new projects don't have do develop an entire platform from scratch. Further, it allows to use a reputation system across multiple platforms which are built on top of the Origin Protocol. Imagine your Airbnb reviews can also be included in your Uber profile etc.
Origin Protocol has already partnered up with Beetoken (https://www.beetoken.com/), which also tries to disrupt the home-sharing economy. Their team and concept looks promising. They also included a decentralized dispute resolution, which I think is crucial in decentralized economy.
There are other market places (such as Uber competitor) built on top of the origin protocol which are listed on their website which set a new standard in decentralized economy.
