According to the relevant page information, the Bittensor dTAO upgrade has been completed. Currently, various subnet tokens can be traded on DEXs such as taosats. The dTAO upgrade is considered to be Bittensor's most significant upgrade since the network's inception. The upgrade aims to transform the distribution of issuance allocations from trusted capital allocations for a few large validators to pure market power. Each AI marketplace (now the TAO subnet project) will operate with its own token, and the issuance will flow based on the relative price of the tokens.
