Hello. I read the post about beta.steemit.com and decided to go. Quite an interesting solution. But I, as a developer, am interested in whether they are centralized or the functionality is implemented in the Steem blockchain? Whether they are associated somehow with the future of SMT. Honestly, I thought beta.steemit.com - this is a test network with SMT.
Thank you for your answers.
P. S. About the tags.
Clicking on the steem tag under the post, hoped to find all posts with this tag in a particular community, but the site brought up a common feed. I think it's not very convenient.
