Free allowance
Permissionless GPU network of 128 subnets where a subnet slot is bought by burning TAO: the cost is 'potentially thousands of TAO', doubles after each registration, decays linearly, and 'becomes the new subnet's initial TAO pool reserve, a sunk cost, not a refundable deposit'.

Identity

Binding limit
write-gatedThere is no free lane: a subnet slot costs 605.7 TAO at the 2026-10-22 chain state, and mining needs a GPU a user does not own, so capital fails before identity does.

Composes withA rented GPU pointed at an uncontested subnet is the only route without owned hardware: the burn is then 0.0005 TAO, but emission depends on that subnet's incentive mechanism, which varies per subnet and is not published in one place.
Reliabilityno reliability event recorded
Notes605.7 TAO at USD 256.94 is USD 155,629 for one subnet slot; the maximum miner burn of 100 TAO is USD 25,694 on the most contested subnet. The registration cost is a third-party chain read rather than a vendor page, so the dollar figure rests on a dashboard plus a price quote. Per-subnet emission rates were not read.
