A Blockchain based Smart Agent System Architecture

With the popularity of artificial intelligence(AI), intelligent agents are potential to positively change people's lives in every aspect. Meanwhile, blockchain technology opens a new era of value exchange with trustless security among strangers. Its decentralized architecture and cryptography based data storage pattern bring light to vast application areas with high security and scalability requirements. In this work, we provide a general solution for intelligence application development on blockchain. Specifically, we propose a novel design of a smart agent inspired by the smart contract concept in the blockchain. Based on the proposed smart agents, a system architecture composed by smart agents is built supported by blockchain, where the agent network and blockchain network is overlapped. Then, a demonstration of the proposed architecture is designed in a case where private data required to be "properly protected" in a distributed manner. The implementation of the designed system is further conducted in the Ethereum development environment, showing the effectiveness and applicability of the proposed architecture in developing a secure distributed application.
