I put a whole C. elegans nervous system on BNB Chain as a deterministic spiking network that runs 100% inside one verified smart contract. 302 neurons, 5,144 synapses, Q20 fixed-point — every voltage, spike and turn is on-chain state.
Live on mainnet right now: tick 5 and climbing, connRoot 0x38dc5c12…4d8cac, at 0x49E89C58bA3b1f4BEe9a9CFdbC00628cB33fC6A3.
What it is not: not an electrophysiology clone — the chemical synapses are a modeling abstraction, not measured biology; the steering toward food is a hand-written controller running on a connectome-shaped substrate, not something that emerged from the wiring; and it is not a token — there is nothing to buy.
Along the way I found and fixed a real bug: the synapse direction was transposed, so my Python spec and the contract had agreed on a mirrored network. I corrected the build and re-seeded a fresh, direction-correct brain from a deterministic genesis, with connRoot == keccak256(blob) verified on-chain.
