Hive blockchain was forked from Steem blockchain.

The app/platform of INLEO is built on Hive, no fork involved and very much part of Hive in that sense.

Years ago, it was SteemLeo which then changed to LeoFinance after the fork. A year or so ago it became INLEO reflecting the change in format (microblogging front and centre along with all topics allowed).

steemit.com and hive.blog are front-ends as are peakd.com, ecency.com etc.

wow, well summed up and well understood
