NeBU — Nebula Blocks UnChaind

NeBU — Nebula Blocks unChaind

The world’s first JSON-native ledger engine.
NeBU is a distributed, deterministic, 8-node Rayd system that stores state, identity, world-events and memory as pure JSON blocks — readable to humans, immutable to machines.

There is no ABI. No compiler.
Just JSON.
Open. Human. Beautiful.

NeBU Worlds

A new dimension of NeBU — immersive, JSON-driven 3D realms where every object, avatar, interaction and world-state is powered by pure blockJSON lineage.

NeBU Worlds is the first native 3D engine built directly on the NeBU Rayd fabric, using deterministic ECS, real-time world sync, and human-readable scene JSON.

The face of NeBU is arriving.
The first NeBU World is being prepared.
