It doesn't seem like a regular Juinjutsu as for me. Given Kawaki's words about the end of shinobi era, I presume that the tatoo is some kind of power with no connection to the regular chakra, akin to Gelel Stone power, and this Kawaki's power is responsible for the Konoha destruction/Naruto's possible death, but since Boruto does possess it too, he's kinda the only person capable of stopping him.
