If they were to add source links, I won't call them plagiarism here. Because all the definitions like Solana or Binance smart chain are the same. We can't change it anyway. But likely we can write is ourselves for a better experience. But whole the theme is the same and we can't change any part. They did a mistake by not adding the sources.
Yea, likely they will come here with the same excuse and will blame their writers. That will prove the team's irreversibility.
The same thought crossed my mind when I strolled through their litepaper and crosschecking them with the plagiarism checker, that if only they added bibliography on their last page, their action will be justified --I even checked their last page to see if they did this, which unfortunately they didn't. Nonetheless, the plagiarism of abstract can hardly be acceptable. Copying definition --with proper citation-- and description of things from existing media is acceptable, copying an abstract, though, is something that's entirely different.
