I read an article of what is about HIVE atomic swap protocol.
I am not a professional on this concept and relevant software engineering, but it may be almost HIVE version of Uni Swap protocol.
The link to “We're not in Kansas anymore!”
As far as I understand, the project may try to make it possible trading HIVE and its HIVE-engine token that may be called “Layer 2 token” in the project.
Now the project seems to be the stage of funding to develop Hive DAO. I hope it will be succeed for Hive blockchain and its community.
My low level of understanding may make others confused, so please let me know if there are any misunderstanding.
I found the website for this project relevant one.

DLUX seems to be the name of this protocol token. Very interesting things are going on. VR looks also one of the concept of this project.

As far as I understand, this protocol DLUX is a sort of bridge to connect HIVE/HBD with its sub tokens and other blockchain ecology.
There may be some key points and concepts and then need to prepare many technical support and developments.
Nodes to connect each ecologies and liquidity enough to run smoothly that need much investment in early stage.
