Preface
The Zytron engine plays an important role in the Zypher Network system, providing developers with a sovereign, customizable Layer3 Rollup infrastructure, matched with a ZK engine that features a universal zero-knowledge protocol template. With the collaboration of the Zytron engine and the off-chain distributed computing network, it can provide perfect support for game operations in a decentralized manner, no longer relying on centralized servers, that is, serverless or server abstraction.
Blockchain games represent a new trend, but the existing industry facilities are insufficiently designed to support games running entirely on-chain. A compromise solution is Web2.5, which places game logic on centralized servers to ensure a better experience for players while placing economic models, smart contracts, etc., on-chain. The operation of the game requires constant communication between these two parts, which also leads to certain limitations in trust, security, and operational efficiency.
In this context, Zypher Network has taken the lead in launching a server abstraction solution based on a series of technologies such as ZKP, modularization, and Layer3.
In this solution, the Zytron engine plays an important role in the Zypher Network system, providing developers with a sovereign, customizable Layer3 Rollup infrastructure, matched with a ZK engine that features a universal zero-knowledge protocol template. With the collaboration of the Zytron engine and the off-chain distributed computing network, it can provide perfect support for game operations in a decentralized manner, no longer relying on centralized servers, that is, serverless or server abstraction.
Overall, Zypher Network not only significantly lowers the threshold for developers to develop and migrate games on-chain but also provides secure, reliable, and efficient support for game operations in a decentralized manner.
Currently, Zypher Network has launched the Layer3 pre-mainnet of the Zytron engine based on the Layer2 network Linea, revealing that the Zypher Network game engine system will fully start operating.
Zytron Engine: Modular, Customizable Sovereign Layer3 Stack
Before introducing the Zytron engine, let's first briefly introduce the concepts of Layer3 and modular blockchain.
Layer3 and Modular Narrative
In fact, Layer2 is usually a non-sovereign chain built around Layer1, existing primarily to scale Layer1. For example, in the Ethereum ecosystem, OP Mainnet, Arbitrum One, Base, Linea, and hundreds of other Layer2 networks aim to further alleviate the pressure on Ethereum Layer1. Layer2 typically aims to become the application layer of the Ethereum ecosystem, where applications are deployed on Layer2, transactions occur on Layer2, but the final transaction verification returns to the Ethereum Layer1 mainnet, while these Layer2s rely on the security and finality of Ethereum Layer1.
So why is Layer3 needed?
In fact, Layer2 is essentially a form of public chain, meaning all developers can develop applications on Layer2. Although different Layer2s adopt different technical solutions to enhance performance, all transactions occurring on Layer2 still imply a certain carrying pressure. Layer3, on the other hand, is positioned as a dedicated application layer. For example, if I want to create a game, I can launch a dedicated Rollup layer in a customizable manner, serving a single application, or a targeted App Chain, thus avoiding interference from other applications. The relationship between Layer3 and Layer2 is similar to that between Layer2 and Layer1, obtaining support for security and finality from the upper layer chain.
A previous research article by Coinbase on Layer3 indicated that compared to independently operating a Layer1 or Layer2, Layer3 can reduce operational costs by about 1000 times. It stated that the annual cost of operating a Layer2 is approximately in the 7-8 digit dollar range, while operating a Layer3 chain typically only requires $25,000-$50,000. Therefore, establishing App Chains in Layer2, as some previous on-chain derivative protocols like dYdX and Perpetual Protocol did, is no longer a wise choice, and Layer3 may be the new trend.
One reason for Layer3's low cost is the modular solution. Layer3 has better flexibility compared to Layer2, as it can modularly select different layers without bearing independent costs. For example, in most Layer2s, data availability accounts for over 95% of total costs, while Layer3 can choose DA services from external sources in a plug-and-play manner, avoiding the costs of independently running a DA layer. At the same time, most Layer3s possess sovereignty and do not need to rely on the upper layer in multiple aspects.
This brings us to another concept, the modular narrative mentioned above.
The modular narrative is easier to understand; we can compare a traditional chain to a computer where all components are welded together. This computer typically has components that are difficult to replace, and every time a new function is desired, a major upgrade is needed, constantly seeking external solutions, such as in the Ethereum ecosystem. Modularization represents a new chain approach, where all parts are pluggable and combinable. Various components of the chain can be selectively replaced, such as choosing Celestia for the DA layer, integrating validation into EnginLayer, and the settlement layer can choose different Layer2s at any time. When the network wants to achieve functional upgrades or expansions, it can plug and replace the aforementioned layers, such as replacing Celestia with Polygon Avail, without requiring major upgrades.
Therefore, if we understand the concepts of Layer3 and modular blockchain, we will gain a new understanding of the Zytron engine.
Zytron Engine
- Development and Deployment
First, the Zytron engine supports developers in customizing the Layer3 layer through its underlying stack, which can be said to be an APP Layer3 Chain dedicated to a specific game. This chain, or Rollup, specifically serves a single game. The way to build Layer3 is modular, meaning you can choose different modules in a plug-and-play manner based on the characteristics of your game. Currently, the Zytron engine defaults to using Celestia as the DA, while the settlement layer and security mainly derive from Linea Layer2 (the current mainnet is on Linea, and new mainnets will be launched on more Layer2s in the future).
On the other hand, not only can you launch your Layer3 Chain in a modular way through the Zytron engine, but the Zytron engine also provides a series of plug-and-play tool components, including: basic hashes, elliptic curve cryptography, masks, Shuffle, and other small tools; SDKs for application-specific circuits; and a series of on-chain validators, etc. Based on these components, developers can achieve pluggable ZK functionalities, tool and circuit combinability, and third-party DSL/ZKVM integration, among others.
With this, developers can build autonomous worlds, small strategy games, or migrate AAA games to their own Layer3 chains at the lowest cost and without a steep learning curve, while retaining production-level UE. Even if developers are not very familiar with ZKP, they can still achieve rapid development based on the series of tool components or migrate existing games with low barriers.
Currently, with the help of the Zytron engine, developers can further deploy games on TON (especially suitable for some mini-games) and use Telegram as an entry point to capture users from the Telegram market with low barriers and on a large scale.
- How to Ensure Efficient Game Operations?
On the other hand, the game itself is deployed on-chain, specifically within the ZK circuits of the Zytron engine, so the game logic runs entirely on-chain. How can we ensure smooth game operations?
- On-chain and Off-chain Combination
First, games running in the Zypher Network do not generate a transaction for every game action and verify it individually as before. Instead, they aggregate the action logs generated by some continuous game behaviors into ZK proofs. Within a certain period, these game actions (each being a transaction) are aggregated into a single ZKP proof. The process of generating ZK proofs occurs in an off-chain distributed computing network, implemented by off-chain nodes. Ultimately, multiple proofs are submitted to the chain as a single transaction. This method not only significantly reduces Gas fees (even achieving 0 Gas) but also ensures a no-latency gaming experience for some PvE game deployments.
In other words, Zypher Network separates the most computationally intensive and complex ZK proof generation from the Zytron engine, greatly reducing the on-chain carrying pressure. This method allows for parallel generation of ZK proofs, making it scalable and efficient, driven by an economic model with a reward and punishment mechanism.
- Optimized Precompiled Contracts and P2P Node Network
At the same time, Zytron not only provides some precompiled contracts but also executes contracts by sharding the data services of chain nodes. Sharding technology allows contract execution to occur simultaneously on multiple nodes, enabling parallel execution, thereby significantly improving processing efficiency and reducing latency.
More specifically, on-chain nodes are connected through a peer-to-peer (P2P) network. This network is specifically used for contract verification, ensuring that nodes can communicate directly and efficiently. The benefit of using a P2P network is that it reduces intermediate transmission steps, making data transfer faster. Additionally, communication and address localization between nodes utilize the Kademlia algorithm (an efficient distributed hash table DHT algorithm), whose structured design allows nodes to find and contact other nodes more quickly and accurately.
In execution, Zytron also shards the contract execution process based on the node distance rules defined in the Kademlia algorithm. This means that different parts of the contract are assigned to different network nodes for execution based on the distance between nodes. This distance-based allocation helps evenly distribute computational loads across the Zytron network, thereby improving the overall speed and efficiency of the system.
- Database
To further enhance data processing efficiency, the Zytron engine integrates more user-friendly relational databases and caching databases, further optimizing the database, significantly improving data processing efficiency for game operations.
- Integration with EnginLayer
In addition to the above designs, the Zytron engine has also modularly integrated with EigenLayer and deployed the AVS computing layer. Developers can integrate this service into their Layer3 APP Chains, significantly lowering the PoS threshold in games, enhancing security, and improving game operational efficiency.
Currently, the processing speed of Zytron's zk-SNARK stack is over 10 times faster than any Layer2, with Gas costs being over 200 times lower. Meanwhile, all players can obtain Zero Gas SBT through games and activities, ensuring a smooth gaming experience (0 Gas). Zytron also supports the Telegram Mini App (TMA) interface, allowing game applications to improve user acquisition rates through hyper-casual games and Web3 native financial tools.
With the help of precompiled contracts, developers can efficiently handle resource-intensive tasks such as cryptographic operations.
The following are some specific details about the Zytron engine Layer3 mainnet:
Summary
Based on the Zytron engine, Zypher Network is paving the way for the next stage of development in the blockchain gaming sector. On one hand, it supports developers in low-threshold deployment and migration of games based on a full suite of ZK solutions and toolkits, establishing a dedicated gaming infrastructure in a modular, Layer3 manner. On the other hand, through the server abstraction solution, game operations no longer rely on centralized servers, balancing decentralization, efficiency, and security, providing players with an excellent gaming experience.
Moreover, elements such as game logic, token economic models, smart contracts, and other series are no longer fragmented and parallel; through a new dynamic combination, they are expected to make games more vibrant and creative. Even AAA games with complex game logic can be deployed and run perfectly in the form of blockchain games.
The Web2.5 form of blockchain games is an unsustainable state, and the transition from Web2.5 to Web3 is an inevitable trend in the development of blockchain games. Zypher Network is becoming an indispensable catalyst in this process and is leading this trend.
