The implementation of confidential transactions in Monero is called "RingCT" because it's implemented as a part of the ring signature construction, so you're definitely on the right path with that thought :)

Note that bulletproofs are a drastically more efficient way of handling the proofs in confidential transactions and are just a part of them.

Right a combination of Adam Back's proposal called "confidential transactions" and "bullet proofs". Thought you guys lumped them together and just called it "v2" or something.
