Fetch.AI is developing a decentralized, AI optimized marketplace for data. Trading on their decentralized network will be performed by Autonomous Economic Agents (AEAs), that will execute transactions without human intervention. These agents will perform tasks, such as delivering data or providing services, and will receive Ethereum-based Fetch tokens as an incentive. Fetch.AI's Open Economic Framework (OEF) will use AI and blockchain to enable these autonomous agents to optimize trading activity in real time.
