What network is the DeepBrain Chain on?

Could you elaborate on the underlying network infrastructure that the DeepBrain Chain operates on? I'm curious to understand the technological foundation that supports this ambitious blockchain project. Is it built on a well-established blockchain platform like Ethereum or Bitcoin, or does it employ a proprietary solution? Understanding the network's underpinnings would greatly assist in assessing its potential scalability, security, and interoperability with other blockchain solutions. Additionally, is there any information available regarding the network's transaction speed, throughput, and overall performance?
