Cost to register —

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.

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, the lowest-ranking subnet will be deregistered.

New subnets have 4 months of immunity.
