Game studio Lattice has announced a partnership with Optimism for the 3D autonomous metaverse game OPCraft.OPCraft is an Autonomous World—a fully on-chain virtual space where every single aspect of the World—every river, blade of grass, and patch of snow sitting atop the mountain ranges—exists on-chain, and every single action in the World happens as an Ethereum transaction.

OPCraft runs on an op-chain; meaning the blockchain is mainly being used towards updating the World as players modify it. Just like a normal rollup, developers can deploy smart contracts on this chain and anyone can run a node in order to access it.

OPCraft’s network runs on Optimism’s OP Stack architecture, with simple adjustments made for higher throughput and shorter block times.

At present, the game's contracts and clients have been open sourced, allowing players to deploy on other EVM-compatible chains. The OPCraft world will be open for two weeks. At 7:59 Beijing time on November 1st, it will stop running, the Rollup will be frozen, and the player's creation in the game will be permanently saved.
