Subnet

Subnet architecture

How the Tensorbox subnet is structured — miners, validators, scoring, and the protocol contract.

High-level shape

Like every Bittensor subnet, Tensorbox is a closed loop:

operators ──▶ miners ──▶ outputs ──▶ validators ──▶ scores ──▶ emissions ──▶ operators
                  ▲                                                          │
                  └──────────── feedback signal ─────────────────────────────┘

The interesting bits are:

  • The task. What miners are actually being asked to produce. (See the task spec once published.)
  • The scoring function. How validators grade miner outputs. This is the contract — change it and you change the entire economy.
  • The reward distribution. How TAO emissions flow back to participants based on validator scores.

This table will be filled in and locked once we finalize numbers. We'd rather ship a TBD than a number we'll have to retract.

Why these choices

The hardest design question in a subnet isn't "what should miners produce." It's "what should validators measure." Get the second wrong and you get a market that optimizes for the wrong thing.

We picked the current scoring function because:

  1. It's falsifiable. Two validators with the same input should get the same output. No fuzzy human judgment in the inner loop.
  2. It's cheap to compute. Validators run on commodity hardware; we won't accidentally exclude small operators by needing a GPU farm to validate.
  3. It's robust to gaming. We tried to break it before shipping it. Open issue if you find a hole.

Open questions

  • How aggressively do we deweight stale outputs? Currently linear decay; experimenting with step functions.
  • Should validators see each other's scores? Currently no; this prevents trivial copying but also slows convergence.

These are the kinds of things that move between releases. The changelog tracks them.
