Quarkslab's team performed a cryptographic and security assessment of both the Bulletproof and MLSAG protocols in Particl. Bulletproof is a non-interactive zero-knowledge proof protocol, while MLSAG is a new ring signature protocol. Both are to be used in cryptocurrency transactions to ensure that they do not leak the amount exchanged or the exact identity of the buyers.
