I'm not fully understanding this paragraph, what is not possible?Darksend's mixing is performed on Masternodes, which have the responsibility of signing the transactions. For each round of Darksend, a random Masternode is elected to perform the coin mixing. Masternodes are trust-less, in the sense that they cannot steal user coins, however they do know where the coins are coming from and where they end-up to. This will not be possible with Darksend+ (RC4), which combines multiple Masternodes in order to prevent full knowledge of inputs/outputs.
According to that paragraph, it's not possible with RC4 for individual Masternodes to know where the coins are coming from and where they end-up. But surely the first Masternode will know where the coins are coming from, and the last one will know where they end up, and if only one round of mixing is used then a masternode will know both. Maybe it needs an edit.I'm not fully understanding this paragraph, what is not possible?
I can explain it to you, but dont have time to write updates myself.The article has gotten a bit dated. Could someone write a brief description of InstantX? I'd do it myself, but I don't think I understand how it works well enough. The History section could use some fleshing out too.
