Deep brain chain was established in November, 2017. Its vision is to build a distributed high-performance computing network with unlimited capacity based on blockchain technology, and become the most important infrastructure in the 5g+ai era. The deep brain chain consists of two important parts: the high-performance computing network and the blockchain main network. The high-performance computing network was officially launched at the end of 2018, and the blockchain main network was launched on May 20, 2021. The main network of deep brain chain is developed based on Boca substrate. Deep brain chain is also one of the few high-performance computing projects in the blockchain industry to achieve large-scale implementation. Since its establishment, deep brain chain has been committed to improving the ease of use of deep brain chain computing network and promoting the commercialization, and has made great progress. It has been widely used in blockchain, artificial intelligence, cloud games, visual rendering, biopharmaceutical, semiconductor simulation and other scenarios, It has provided many enterprises with high-performance GPU computing power. Nearly 50 manufacturers around the world have deployed high-performance GPU cloud platforms based on deep brain chain network, serving hundreds of enterprises and tens of thousands of AI developer groups.
