The OpenTensor Foundation has reintroduced Bittensor's subnet registration mechanism, setting a cap of 128 subnets and implementing a four-month immunity period for new entries. Effective October 16, this update aims to enhance subnet quality and foster competition by allowing the replacement of underperforming teams. The change is expected to boost demand for TAO tokens, as teams will need to stake them to secure registration slots. The Bittensor community is actively engaging with the update, particularly on Discord, although no major announcements have been made by key figures.
