Sorry, I meant to say range proofs, and although they are pretty old, I see now that Moneros specific implementation is actually relatively new
Discussion
Ah, was wondering as I was reading along what the chronology might be. That seems about right from what I remember
I think the specific implementation of Pedersen commitments is live since RingCt was introduced in January 2017
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. 📝
worth noting the difference between a theoretical issue and and implementation one.
this is an *implementation concern.
ie, the maths aren't suspect, the concern is around how its applied.
as with Bitcoin, if you cant verify the implementation yourself,
what techniques can a person use to establish trust?
