Bittensor: subnet work, TAO and alpha

Bittensor connects independent markets for digital work through the Subtensor blockchain. Subnets produce model responses, compute, storage or predictions. Their participants receive tokens under the network’s incentive rules. TAO is the chain’s native coin; each subnet has its own alpha, and root participants accrue a share of a separate asset basket.

TAO, a subnet’s alpha and root basket shares

A position is identified by its asset and subnet. Its balance, market value and amount available on exit describe different things.

TAO

The native Subtensor coin

TAO transfers value on the chain and normally pays transaction fees. Root positions retain their principal in TAO. A native balance uses the Bittensor address and network selected for the transfer.

ALPHA

An asset belonging to one subnet

A subnet position holds that subnet’s alpha. Entering sells TAO for alpha; exiting sells alpha for TAO. The subnet number, or netuid, identifies which alpha is held.

β

A share of one root basket

Beta measures a share of a chosen root participant’s basket. The basket holds subnet positions; its TAO value follows their realizable sale quotes. Beta is recorded as a share count for that basket.

Producing work, scoring it and confirming blocks

A subnet sets the task and reward rules for its participants. Subtensor records their positions and distributions; its block-production mechanism operates separately.

OWNER

Define a subnet’s incentives

The owner registers the subnet and configures its incentive mechanism. The task can concern inference, hardware capacity, storage or another digital service.

MINER

Produce the requested result

Miners deliver the work their subnet asks for. They compete for registration slots and rewards under that subnet’s quality and resource requirements.

SCORE

Score subnet participants

Subnet validators score miners and submit weights. Yuma combines these evaluations with participant weight to determine rewards inside the subnet.

BLOCK

Produce and finalize chain blocks

Subtensor uses an approved authority set. Aura assigns block-production slots and GRANDPA finalizes the chain. These authorities handle block consensus.

TAO and participant positions

Subnet alpha or root TAO: entry, accrual and exit

A subnet entry exchanges TAO through its reserve and records alpha against a selected subnet evaluator. Root entry retains TAO principal and accrues entitlement to that participant’s separate basket. Each route has its own claim and exit.

Subnet alpha

  1. 01Choose the subnet and evaluator
  2. 02Exchange TAO through its reserve
  3. 03Record alpha in the position

Where rewards accrue

The position earns its share of the evaluator’s subnet rewards after the evaluator’s take. Accrual is denominated in that subnet’s alpha.

How assets return to the wallet
Sell position alpha back through the subnet reserve. The quote includes swap costs and trade impact; an execution-price limit can restrict or reject the fill. A completed ordinary exit returns spendable TAO. An optional conviction lock sets a minimum alpha balance that must remain on the subnet. Only the amount above that minimum can be withdrawn; a decaying lock lowers the minimum over time.
What changes the position
Alpha’s TAO price, reserve depth, accrued rewards and the evaluator’s take. Entering or exiting also changes the reserve, so a large trade can move its own execution price.

Root TAO

  1. 01Place TAO on root
  2. 02Accrue entitlement to a basket
  3. 03Claim into root TAO stake

Where rewards accrue

Root dividends accumulate as subnet assets in an escrow basket. Your entitlement is a share of that basket, while the original principal remains TAO on root.

How assets return to the wallet
A claim sells the owed basket share and adds the resulting TAO to the root position. If the network enables a root hold period, claiming restarts it: wait until it ends, then withdraw TAO separately. Removing principal without a claim leaves basket entitlement owed.
What changes the position
The basket’s assets, their realizable TAO quotes and the participant’s take. Accrued value changes with the basket; the original TAO principal is accounted for separately.

Use model inference, GPU workloads or chain tools

Compute products expose model APIs, hosted workloads and hardware capacity. A customer selects the service and pays its product tariff; subnet participation follows the network’s registration and reward rules.

Model inference and serverless compute

Chutes

Chutes serves open models through an API and provides Chat for direct use. Custom Chutes packages a model or application for hosted execution; its compute network participates in Bittensor subnet 64.

GPU virtual machines and sandboxes

Targon

Targon rents GPU virtual machines, dedicated servers and short-lived sandboxes. Workloads can be managed through its API, CLI or SDK; Manifold sources capacity through a Bittensor market and longer-term enterprise contracts.

Bittensor transactions and queries

Bittensor SDK

The Bittensor SDK and btcli read chain state, manage keys and prepare participant operations. Plan previews costs and effects before execution; policies can bound fees, spending and permitted subnets.

Receive native TAO and choose the signing key

A coldkey owns funds and signs transfers, registrations and position changes. A hotkey performs subnet work and submits evaluations. The operation determines which key signs and what balance pays.

01

Select the Bittensor receiving network

Open a native TAO receiving address in a supporting wallet. A transfer through Finney reaches Subtensor; a token using the TAO name on another network uses that network’s own asset route.

02

Choose the operation and participant

For an alpha position, select a subnet and evaluator. For root, select the participant whose basket accrues your entitlement. Producing or evaluating work also requires the subnet’s registration and resource setup.

03

Preview, sign and read the result

Plan shows predicted balance changes and fees. A subnet quote includes trade impact; a price limit controls execution. The receipt identifies the chain block and the resulting position.

Token rewards, swap costs and transaction payment

Ordinary chain operations usually pay TAO from the signer’s free balance. A subnet entry or exit also incurs its reserve’s swap charge, taken from the input asset. The two payments have different destinations.

Network token issuance

Participant rewards inside a subnet

The standard alpha allocation is 18% to the owner and 41% each to miners and evaluators with their supporters. If total miner incentive is zero, the miner portion goes to evaluators.

Participant entering or exiting

TAO and alpha reserve swaps

The subnet sets its swap-fee parameter. Moving between evaluators inside one subnet uses a separate position-transfer operation.

Hold TAO, support a participant or do the work

Each path gives a different position: a spendable TAO balance, a recorded share of participant rewards, or a registered role producing and evaluating work.

TAO

Use a free balance

Free TAO can be transferred, used for chain operations or moved into a participant position. Accrual begins under the rules of the position you create.

POSITION

Back a selected participant

A subnet position holds alpha and receives its reward share after take. A root position keeps TAO principal and accrues basket entitlement. The participant’s operation and fee affect the result.

WORK

Supply or evaluate a service

A registered miner supplies the subnet’s product; an evaluator scores the work and submits weights. Each subnet sets resource requirements, admission and competition for participant slots.

Practical questions

1Is a Bittensor subnet an Ethereum L2?

A Bittensor subnet is a market for a particular kind of work. That work runs outside Subtensor, while Subtensor records participants, balances and incentive distributions.

2Can holding TAO make me a block producer?

Subtensor assigns block production to its approved authority set. Subnet participation and TAO positions follow separate registration and incentive rules.

3What do I hold after entering a subnet?

The position holds that subnet’s alpha against the chosen evaluator. Its TAO value depends on the alpha price, and the amount received on exit also includes swap costs and trade impact.

4Does a root claim transfer TAO to my free balance?

A root claim sells the owed basket share and adds TAO to the root position. A separate root withdrawal returns spendable TAO to the wallet.

5Are network rewards paid from model customers?

Bittensor rewards participants through its token issuance and allocation rules. Customers pay the selected compute or inference service under that product’s tariff.

6Why does a quote differ from a spot valuation?

A sale uses the reserve’s available depth and changes that reserve as it fills. The exit quote accounts for this trade impact and fees; a spot valuation multiplies the position by the displayed price.
