Subnet Registration

Subnet registration and deregistration are live on the chain.

Anyone can register a new subnet by paying the current registration (lock) cost in TAO. The cost is demand-based: it rises as registrations become more frequent and decays back down over time.

Current registration cost

Read the current lock cost with the Bittensor CLI:

btcli subnet lock_cost
>> Subnet lock cost: τ3,796.780457067

The live and historical cost is also available programmatically:

• Get Subnet Registration Cost (latest)
• Get Subnet Registration Cost (history)

Or view the historical chart on the Subnet Home.

Where the cost goes

A portion of the registration cost is paid into the subnet's liquidity pool (with a matching amount of alpha minted to hold the price); the remainder is recycled.

The registering owner does not receive a matching alpha allocation. The earlier "alpha-to-owner" mechanic — where the subnet owner was minted alpha equal to the lock cost at registration — has been removed. Owners now participate in their subnet's economics through the dTao market like any other holder.

Registration cadence and cap

Once a subnet is registered, there is a 4-day window before the next registration can occur.

If the current maximum number of subnets has been reached, registering a new subnet deregisters the lowest-priced subnet (subject to immunity — see below).

Immunity

New subnets have 4 months of immunity from deregistration.

Deregistration

For how a subnet is chosen for deregistration and how alpha holders are paid out, see Subnet Deregistration.
