OK, i was thinking we need private ether accounts, i can't share my ether addresses with my friends cause they'll know how much tokens and ether i own in my wallet. That's horrible for mass adoption.
I read metropolis: byzantium was going to be a ethereum fork with zk-SNARKs which will hide balances and transaction amounts, but i can't find out when this is going to happen? And it will be after casper or before? I can't figure out which fork is first and when this going to happen or if both forks will happen simultaneously. I really want this privacy feature in ethereum, also if this forks happens it means i will have my ether and tokens twice in both chains? I'm confused i will appreciate an answer. I can't wait to login to my private wallet via trezor/myetherwallet .
Can't answer everything but no, its not a hardfork. It is a softfork so you won't get duplicates and stuff like that. I also THINK they happen simountaniously or very close to eachother.
