Not sure exactly. If I understand correctly, it’s being touted as a more efficient way to obscure outputs compared to ring signatures (or in conjunction with ring signatures). Might improve scalability and efficiency, perhaps, while preserving privacy, but I’m not technical enough to know.
I’m sometimes wary of changes, because Monero works pretty well, but I also know that if it doesn’t keep up with technological changes, it could become obsolete, or succumb to some threat.
