Sovereign Generative Game-World Provenance with Per-Voxel and Per-Object Signing.

Per-voxel, per-spawn-event, and per-biome cryptographic signing of a real-time generative game world.

A method and system for cryptographically signing the contents of a real-time generative game world at three nested levels of granularity. Every voxel chunk is partitioned, hashed, accumulated into a chunk Merkle tree, and signed under an operator-controlled post-quantum signing key; every spawn event emits a signed provenance record carrying object class, geometry hash, texture hash, generative-prompt lineage, and signing identity; biome-level Merkle accumulators bind contiguous chunk roots and spawn records into a per-biome chain hash-linked into the operator audit record. A regulator, age-rating body, IP-clearance counterparty, or downstream asset licensee given the world, its audit chain, and the operator's public key can verify the provenance of any voxel, any spawned object, and any biome region back to its originating generative prompt.
