As far as i understand Monero currently uses range proofs (Soon to be bulletproofs) to prove that when an amount of Monero is sent that amount is between 0 and some large number. this is to protect against negative amounts being sent My question…

I am reading the source code of Monero. In the Bulletproof prover, there is always a line like T1 = rct::scalarmultKey(T1, INV_EIGHT). Why is there always a INV_EIGHT multiplication with the point? Can anyone help me? Thank you.

For example imagine the situation where i have one unspent output valued at 0.5 XMR In another wallet i also have another unspent output valued at 0.5 XMR even thought these outputs share the same values they have different history's when i…
