Brandon Goodell (aka Surae Noether)1 has concluded2 that Generalized Bulletproofs (GBPs)3 are suitable for use after completing a review4 of the security proofs5 produced by CypherStack6:

My general results: Overall, GBPs are suitable for use, I think they are secure. [..] If the proofs of security for BPs are up to industry standards for a classically-secure cryptosystem, then the proofs of security for GBPs probably are, also.

Justin Berman7 has praised the work suggesting that the report gives confidence in GBP’s used in FCMP++8 and echoed the author’s recommendation to prioritize research into potential Bulletproofs and GBPs attack vectors.
