Will take your word for it as that’s deep in the weeds for me. I realize now I don’t know the chronology of a lot of the pieces. CTs were invented in 2014, or was that just the optimization by Blockstream and they date back further? I could look this stuff up, but if you happen to know please share. Ring sigs, range proofs, (anything I’m missing?) created quite a bit earlier?

pretty sure the idea of RingCT predates Bitcoin
i think it was Nick Szabo...?
ring signatures too, i think the idea is from before bitcoin.
range proofs,
which are the foundational maths,
are ancient.
mostly developed in the cryptography boom of the 80s and 90s I think.
Sounds right. I might have to dig a little just to satisfy curiosity on all these things
nice basic explanation here
Looks worth reading. 📝
