FETCH.AI (FETCH) is a blockchain project with machine learning and artificial intelligence as the core. It aims to create a self -learning economic agent network to promote economic activities and collaboration between AI agents. The following are some key information about the FET tokens and fetch.ai projects:FET tokens: FET tokens are local tokens of the fetch.ai network for various economic activities on the platform. It is divided into the participation of various transaction costs, reward nodes and agents on the network, and act as the medium of value exchange between economic agents.Project Vision: FETCH.AI's vision is to deploy machine learning, advanced encryption and autonomous agents into the blockchain to build a future digital economy. The project aims to provide practical cases for hotels, transportation, energy, and supply chain industries, so that economic agents can independently discover and partners to carry out economic activities.Autonomous Economic Agent (AEAS): The core concept of fetch.ai is the independent economic agent (AEAS), which can be equipment, services or agents themselves. They can perform various tasks for economic transactions without manual intervention. These agents interact with FETCH.AI networks and perform tasks and transactions based on smart contracts.Nodes and tokens mortgage: In order to maintain the security of the network, nodes and agents need to mortgage a certain number of FET token. This mortgage mechanism is a security measure to prevent malicious behavior, ensuring the honesty and legal operation of the participants.Application field: FETCH.AI's application field is very wide, including hotel management, traffic scheduling, energy supply chain, etc. The project provides a new way for these industries to solve complex problems through the collaboration of independent economic agents.In short, fetch.ai is an ambitious blockchain project. It aims to combine machine learning with artificial intelligence with blockchain technology to build an independent economic agent network to promote the future digital economy. FET tokens play key roles on the platform to promote various economic activities and network operations.
