We have framed a high-performance distributed network architecture and blockchain framework with a recursive hierarchy in the past two years. Currently, we are working on a blockchain-based personal data assistant, which can be considered as a trusted network to store and manage personal data, even interact with other services. And we are going to make more middlewares and applications for distributed systems. As a collection of all these works, we call it Trusted Distributed Network(TDN).

Talk Is Cheap, Show Me The Code
