As there are many initiatives to create decentralized artificial intelligence algorithms, most of them work in a way that they weakly integrate the blockchain technology with different blockchain platforms, usually via interfaces and a common tokens that represent some kind of an exchange of the services. Similar projects that successfully made an ICO are for example Neureal, SingularityNET, or Neuromation. However it would be much more interesting to integrate a distributed ledger technology with a machine learning algorithm really on the algorithmic level. It would provide this way a whole integrated algorithm for decentralized artificial intelligence. Certainly it is an open question which AI algorithm can be efficiently integrated with which decentralized technology.
