World Engine is a sharded layer 2 blockchain SDK designed with the needs of game developers and players in mind. The World Engine’s main innovation lies in its sharding design inspired by the server architecture of computationally intensive massively multiplayer online (MMO) games.
Sharding enables game developers to distribute their game load across various shards. Consequently, a World Engine chain can adjust its throughput in response to demand, growing in tandem with the developer or publisher. At the same time, World Engine’s sharding architecture also avoids the interoperability/platform fragmentation issues associated with scaling by spinning up another separate rollup.
The simplest way to get started with World Engine is to build a game shard using Cardinal. Note, this repo is for the core development of the World Engine only, and should not be used for developing World Engine powered games.
Using the world-cli, you can get started with your own Cardinal game shard. Please see getting started for more details.
