Yes solidity implementation is missing the detail challenge part.
And because this project is not my full-time job, I opened a telegram group & discord channel to gather people who wants to make this project together.
This current implementation and research paper has some missing implementations and specifications so we’re going to decide all the detail specification until this year Q1 & want to see the working product until the Q3.
Happy new year and everyone is welcome to join the discussion & implementation process.
