Is this a fork of Zcoin?
anyways, you really engaged me with the name
SERO
is like ZERO but a bit different
Technically SERO is a fork of ethereum with unique implementation of zkSnarks (SERO=SuperZero) which results in smart contract with privacy protection.. this is very high level description therefore I would advise everybody to checK the introduction video
https://youtu.be/UNG2boG49Io and read in the whitepaper.
I looking much forward for things to come.
