The article discusses the design paradigms of the whole-chain game engines Mud, Dojo, and Zypher, and analyzes their different solutions for building autonomous worlds/whole-chain games. Mud from the Lattice team achieves EVM compatibility and developer friendliness through the World development framework, MUD game engine, and Redstone underlying consensus protocol. Dojo targets the Starknet development environment, using the Cario language and ZK-Rollup technology. Zypher Game, based on ZK technology, provides modular solutions such as Secret Engine, AW Engine, and Zytron Kit, emphasizing trustlessness and performance elasticity. The article also discusses the basic narrative of whole-chain games and the implementation paradigms of new primitives, as well as how these technologies drive the development of the gaming industry.
