Insribed Gene

First living, AI-powered creatures on Bitcoin • Genetic Algortihm + Neural Network

Inscribed Gene brings AI‑driven life to the Bitcoin blockchain via Ordinal inscriptions. Each “lifeform” is defined by a “gene” inscription of neural‑network weights that determine its shape and colors, and decision‑making. Lifeforms spawn with full health in a simulated world where faster movement drains energy and food replenishes it. A lifeform can reproduce—splitting energy 50/50 and passing on a mutated copy of its neural weights. The built‑in training simulator lets users pick their own Ordinal lifeform, tweak mutation rates and environment settings, then watch generations evolve, and finally inscribe the fittest child’s gene on the Bitcoin network—upgrading the ordinal’s DNA
