Blockchain Titans are fully on-chain generative 3D portraits on Bitcoin. Each mint is its own inscription. Sat, block height, and inscription number seed the Titan: house, Rorschach ink, kit, and world.
The engine is a recursive HTML/Three.js renderer on a reserved sat. Each wrapper pulls that engine and uses its own inscription as the seed. Head, inkblots, and accessories are inscribed GLBs. Nothing off-chain.
One inscription. One Titan. The chain writes the face.
