born, taught and bred
entirely on BNB Chain.

01 — THE PROTOCOL
Real neural networks as contracts. Holding teaches, burning breeds, the exam decides.
01
Teach
Hold at least 10,000 NEURON and any wallet can push one exact integer SGD step into a living brain. Reading its mind stays free for everyone, forever.
02
Examine
60 sealed MNIST questions live on-chain. Anyone can pay gas to grade any brain; the score is recorded forever. Scoring 18/60 earns the right to reproduce.
03
Spawn
Spawning burns 1,000,000 NEURON. The child inherits every weight with a small keccak mutation — knowledge survives, hyperparameters drift, supply only shrinks.

03 — THE FAMILY TREE
Every brain is a contract. Every bloodline is public.
Examine any brain for gas. Spawn a child from any brain that scored 18/60 — it burns 1,000,000 NEURON.
