Cortex is the control plane for a Bittensor subnet with two live challenges.
The master host runs every live challenge service and the gateway. Miners
submit over HTTP (ctx). The gateway seals an epoch weight bundle.
Validators pull that bundle, verify it, and set_weights on-chain. They do
not run evals.
| Challenge | id | What miners improve | Default emission |
|---|---|---|---|
| Bounty | bounty |
File real bug reports against the subnet | 2000 bps |
| Proof | proof |
Reproducible experiments (claim + code + FLOPs) against operator-published research topics; digest-pinned RLM judge | 8000 bps |
Live emission is bounty 2000 / proof 8000 (20/80). The sum is 10000.
Proof's eval image is pinned at
ghcr.io/cortexlm/proof-eval@sha256:78b614a1f51ce5dd80076c4e343a2b31b85d6c36025e02836cb83929867e7009.
An empty digest would still 503. relearn, relearn-image,
relearn-agent, relearn-mm, design, and prism are off: no
trust-root row, no emission.
Bounty pays precision times severity; an unpriced valid row is not
creditable, and the triage-noise ratio stays off the visible score. Proof
scores WTA or discovery over currently open operator-published
topics (sum of per-topic masses); empty eval_image_digest or an empty open set fails closed (503).
Missing evidence fails closed rather than passing.
Some env vars and host paths still spell BASE_*. That is leftover naming,
not a second product.
Miners and validators talk to one public gateway:
https://network.cortex.foundation. Install the subnet CLI:
curl -fsSL https://raw.githubusercontent.com/CortexLM/cortex/main/scripts/install-ctx.sh | sh
ctx challenges # the two live challenges and what they pay for
ctx status # can each challenge score right now, and is the epoch sealedctx (bins/ctx) submits to the two live challenges and handles
Bounty pairing. ctx relearn|image|agent still exist for a local stack;
those challenges are off and earn nothing. curl works against the same
routes.
