Keystone

Keystone is a rollup SDK for building onchain games hyper focused on performance and composability above all.

We believe that in order for onchain games as a whole to meaningfully expand, we must first and foremost deliver unparalleled experience that the average player is familiar with.

Current features

• High frequency tick based game logic
• State sync with support for emitting events and errors
• Atomic transactions within game logic systems

Coming Soon

• EVM layer that composes on top of the tick-based state machine
• Better code-gen support across platforms (Unity, Typescript, etc)
• UI state explorers, simulation tools
• Parallel execution ???

Back story

After building and launching onchain games ourselves, we realized the following problems:

• Slow performance: Games built using smart contract languages are slow by nature, as blockchain state machines aren’t specialized for games. We cannot build ambitious games with even hundreds of concurrent users.
• Missing critical game features: Since blockchains are async and transparent by nature, missing games like game tick and private information block meaningful games from thriving.
• Isolated developer toolchains: Smart contract languages are unable to leverage existing mature toolchains and ecosystems for games.

Keystone represents a step-function improvement in how onchain games are built. We designed keystone from grounds up to create a high-performance, data oriented game server with the composability of EVM smart contracts (coming soon).
