Bittensor subnet

Mining

Miners ingest settled bundles and the surrounding public chain state and output, per settlement, a leakage score in [0, 1] with a typed finding (timing, size, collusion, linkage). Miners are rewarded for findings that validators can reproduce.

Validation

Validators replay each miner's claim against a held-out labelled set of synthetic leaks injected into testnet traffic, and against each other's reproductions on live data. Miners that report unreproducible findings are down-weighted.

Scoring

Validator weights are aggregated with Yuma consensus. The resulting per-solver integrity score is an exponentially weighted average over recent settlements and is written to the solver registry each epoch, where it gates auction eligibility and scales bid weight.

Registration and activation timeline

Live subnet data does not appear the moment a subnet is registered. Bittensor imposes several steps between registration and real network activity:

1. Registration slot. A registration confirms as soon as it is submitted, but subnet registrations are rate-limited network-wide to roughly one per day (one per 7,200 blocks). If another project takes the current slot, registering means waiting for the next one.

2. Dynamic, non-refundable cost. The registration cost doubles every time any subnet registers, then decays back down over roughly two weeks, floored at a fixed minimum. The amount paid becomes the new subnet's starting reserve; it is not a returnable fee.

3. Immunity period. A newly registered subnet enters a mandatory 7-day immunity period with emissions turned off. This window is for testing miner and validator code before real incentives are active.

4. Manual activation. Emissions do not start automatically when immunity ends. The subnet owner must activate them with an on-chain action. Until then the subnet earns nothing and produces no real activity to display.
