At Consensus 2017, Muneeb and Ryan announced the Blockstack Token. I couldn't find any video of this talk, but I'd love to know more about this.
There is a CoinDesk article that talks a bit about it:
Similar to how domains are today registered for a fee on the internet, the new token will be used to file the registration fees paid directly to the network.
Though technical details about the distribution model and other aspects of the token have yet to be settled, Ali and Shea emphasized this is not an ethereum-based ICO, but rather the sale of tokens created by their own technology.
"Currently, we're launching a single token for Blockstack," said Ali. "And we'll have more details on app-specific tokens later."
This sounds very interesting.
Possibly a response to the question "Why would anyone choose to run a Blockstack server on behalf of others?".
