DeepBrain Chain (DBC) is an innovative blockchain platform designed to decentralise artificial intelligence (AI) computing. Launched in 2017, DeepBrain Chain aims to provide a secure, private, and low-cost AI computing platform by leveraging blockchain technology. This project primarily focuses on the artificial intelligence sector, offering cloud-based, high-performance computing power necessary for AI development. By utilising distributed ledger technology, DeepBrain Chain ensures data privacy, and security, and significantly reduces the computational costs associated with AI research by leveraging idle computing power from around the world. Its native token, DBC, facilitates transactions within the ecosystem, incentivising participation and maintaining network security.
