Fractal Engine

A peer-to-peer world engine for shared spatial realities.

Development + systems architecture[Rust][Bevy ECS][CRDT][P2P]

01 / The premise

How can a shared 3D world retain structure when authority is distributed?

A decentralized 3D digital-twin platform that combines Bevy ECS, CRDT synchronization, and peer-to-peer networking. Escherbridge developed Fractal Engine as an exploration of spaces that remain coherent without a central owner.

02 / What took shape

  • Decentralized scene synchronization
  • Entity-component spatial model
  • Local-first collaboration

03 / Looking back

The useful residue.

Fractal Engine treats the world model as a negotiation rather than a file. The enduring design lesson is that multiplayer architecture begins with a theory of ownership: what may diverge, what must converge, and what each peer can know.
