Zytron - Zypher L3 Engine

Zytron is an open-source, highly modular, future-proof Web3 Game Chain Engine; it provides a sovereign, customizable L3 rollup infrastructure featuring a ZK-engine with universal zk protocol templates. Zytron is tailored for developers to build autonomous worlds, mini strategy games, or migrate AAA games on-chain at minimum cost without steep learning curves, enabling them to migrate assets, game logic, and data storage on-chain while preserving production-level UE to achieve world adoption for billions of gamers.

Core Components

The engine provides 4 plug-n-play core components designed to provide a robust and flexible infrastructure for blockchain-based gaming, addressing various technical requirements and enhancing the gaming experience. Developers can use this engine to run their own gaming chains, with the flexibility to embed necessary features as per their requirements:

Sovereign Rollup: The most important thing in the game is playability, which requires the highest availability(CAP) in the distributed system, and the entire system can be quickly upgraded and automatic deployment.
Server Sharding: Distribute the game’s world map into different nodes to improve the carrying capacity of a single node. At the same time, it provides a set of efficient retrieval algorithms to quickly move on different nodes on the global map, switch different node services, and synchronize information.
Data Compatibility: A crucial component for storage abstraction, this protocol integrates more user-friendly relational and cache databases to expedite game data processing. This feature addresses the need for efficient data management and quick access, which is essential for maintaining a smooth gaming experience.
Customized Network: Recognizing the high network demands of gaming, the framework optimizes the underlying peer-to-peer (P2P) network layer to support gaming scenarios. This includes optimizations for message transmission within small groups, using NAT traversal and hole punching techniques for fast and efficient connectivity. Additionally, the network is tailored with a special UDP protocol designed for games, aiming to keep latency below 100 milliseconds. This ensures quick and reliable data transmission, which is critical for real-time gaming experiences.

Layer3 Chain Template: Elevating Game Development

Moreover, Zytron provides an option for developers to deploy dedicated rollups, transcending the limitations of existing infrastructures for more ambitious games.

Developers can use this template to run their own gaming chains, embedding necessary features as per their requirements. The Layer3 chain interacts with the underlying L2 through a rollup mechanism, inheriting the security of the underlying layers while providing its own proofs. It also includes a smaller-scale zk-Rollup solution, for bridge assets to the source chain for higher consensus security.

Zytron also features a comprehensive suite of precompiled Zero Knowledge supports, including a variety of verifiers like PlonK, Groth16, and Bulletproofs, cryptographic pairing techniques (BN254, BLS12), and elliptic curve (EC) standards (SECP256K1, Curve25519, Jubjub). Additionally, it incorporates efficient hash functions (Anemoi, Recue) and a range of plug-and-play circuits (Shuffle, Rollup, Random, etc.), all optimized for game development.

The network communication within the Zytron is significantly enhanced with the integration of P2P, RPC, and game-specific transports, alongside a Sub PvP ZK rollup(Z4) and a global chain. A local client serves as the ZK rollup service, contributing to a framework that is 3,000 times more scalable than other Layer 3 solutions and maintains full Ethereum Virtual Machine (EVM) compatibility.

Challenge Matrix in Game Development

	Current Limitations	Zypher Solutions
Rapid Operations and Cost Efficiency	Fast operations, there may be 2 to 10 operations per second, including movement and clicks.	Divide the network to many sub zkrollup group for consensus, support million or even billion of tps over the network, and most of the operations do not send to game layer3 chain.
Streamlined Network Synchronization	Each operation needs to be synchronized in the node of the network (Network flooding).	Message only needs to be transmitted in small groups, with customized p2p network, use NAT & hole punching to make it fast and efficient.
Combating High Latency	Latency of over 200 ms is unacceptable (maybe already dead), and the fastest L2 blockchain still needs 2s per block (10x).	With the p2p network, transmission optimization is carried out, and a special up protocol is designed for games, keeping latency below 100ms.
Handling Complex Data	The KV storage of smart contracts is not conducive to multiple complex data and associations.	Built-in more friendly relational database and cache database to speed up the processing of game data.
