Awesome thanks for the PR @spankratov! I'll take a look at this tomorrow.

@spankratov Apologies for the delay. @larrysalibra is on this and will be getting to it in the next couple of days.

@spankratov This is really great!

I tried it with requests and responses generated by blockstack.js and they work!

Couple of things:

1. The name look up URL you're using is a temporary one used by the explorer that will be removed. Since we're trying to encourage people and services to run their own Blockstack nodes, I made the blockstack-ruby library default to the node running on localhost and configurable to another host. In blockstack.js, we have the user pass in the name lookup URL instead of providing a default, It would be cool if we can do something like that in the python library as well. If you think it makes more sense to hardcode a default publicly accessible name look up url, https://core.blockstack.org/v2/users/{name} is a better option.

2. We added an additional step where the app sending the authentication request hosts a manifest file with information about the app. As part of processing the authentication request, the identity provider downloads the manifest from the app. You can see the code here: https://github.com/blockstack/blockstack.js/blob/master/src/auth/authBrowser.js#L84

This is a huge improvement to the blockstack auth library for python. I'm going to merge this PR. Let me know what you think about the above issues. Very happy to accept PRs for them as well. Thanks again!

@spankratov I created two issues #7 & #8 to track the two items I mentioned above.

Thanks, @larrysalibra and @shea256 ! Glad my changes were merged. I agree with two issues you mentioned and I'll take a look on it this week.
