Intelligent agents could travel across networks of blockchains and coordinate resources, execute smart contracts, and return value to the owners of those agents. Imagine for example a driverless car run by its AI. The car may be owned by a number of humans, thousands even, through ownership contracts recorded on a blockchain. The car, or rather its AI, once called to execute a ride via a distributed application, searches a blockchain to ensure that the call is legitimate, executes the ride, and returns the income it collects almost instantaneously to its owners for immediate distribution. Or think of a swarm of agricultural robots collaborating with intelligent sensors and managing efficiently, and with minimum environmental impact, farmland to produce the highest possible yields.
