This feature enables the expansion of the gaming ecosystem. In practical applications, L3 can be used to build a Decentralization game economy system, supporting the circulation and transaction of assets, and increasing the transparency and security of the game economy.

However, the application of L3 in blockchain games still faces some challenges. Although L3 improves scalability, there may still be performance bottlenecks in high-frequency trading game scenarios, resulting in longer transaction confirmation times and affecting player experience. In terms of development, although the modular and highly customized architecture of L3 provides flexibility, it also increases the complexity of development. Developers need to master multi-layer blockchain architecture, smart contract, and encryption technologies, which is a barrier for traditional game developers. In addition, there are also obstacles in the user experience of L3. Due to the dependence on DecentralizationWallet and gas fees, ordinary players may encounter technical problems during the operation. This complexity limits the widespread popularity of blockchain games.

Overall, L3 provides a new technical path for the development of Blockchain games, but before large-scale application, issues such as on-chain performance, development complexity, and user experience need to be addressed.
