Imagine a decentralized version of Uber that connects drivers and commuters, letting them negotiate fares directly.

That’s one possibility with a ride-hailing service powered by the blockchain. An “Uber on the blockchain” might sound like a clumsy attempt to mash together two tech buzzwords, but Chen Weixing, who is building such a service, is a sharing-economy veteran who helped shape the world’s largest ride-hailing market, China. His company Kuaidi Dache merged with its arch-rival Didi Dache in 2015 to become Didi Chuxing, which a year later merged with Uber’s China unit and now dominates ride-hailing in the country.
