Sub Domains


Hi @larry - just letting you know my ‘’ has turned up - thanks!

Also you mentioned editing my zone file to remove the link to dropbox I set in an older version of the portal. Any pointers on how to go about doing this much appreciated?

#2 is this a publicly available feature yet? How can I register a subdomain?


I’d like to know this too. I saw in the latest update that this was a feature that was included, but I haven’t been able to figure out how to do it.


It’s shipping very soon - lucky attendees of the Blockstack Berlin Hackathon got a sneak peak.

They’ll likely be called “sponsored names”

Awesome! Thanks for letting me know!

There’s not a tool for this yet. You could use this function in blockstack.js to do it:


@jude I managed to get the subdomain registrar running, but after attempting to register my first subdomain (which hasn’t gone through after about 12 hours) I also can’t register a new subdomain. Is there a way to kill the previous (pending?) subdomain registration?

@aaron would be a better person to answer this than me.


@jude thanks

@aaron if you could share a way to bypass the spam-features for testing purposes that would be great. I have added the bearer API-KEY but it still says that my IP address went over the max?


Hey @blockpac – this issue would make more sense as a different topic. If you move that question over to a new comment, I’ll be happy to help out!
