The Kaleido public chain implements the Algorand consensus protocol based on the VRF random algorithm, creates a credible P2P communication network at the traffic layer, and introduces a multi-level authority contract mechanism for different scenarios at the contract layer. The focus is on the game industry, creating a purely distributed, highly scalable game industry vertical public chain that can accommodate millions of nodes. The core team of the project are all from big companies such as Tencent and Xunlei. They have more than ten years of experience in distributed system development. The team is committed to creating an easy-to-use public chain.
