In theory, if you validate on the chain that Vitalik doesn't like, he will destroy your 32ETH on the good-boy Vitalik chain.
How will he know I validate ETH-new's chain? I can spend on both chains, and I'm sure he would be fine by the assumption that I'm selling the ETH-new he disapproves of, to buy his ETH-old. But, you can't know with certainty that an ETH-old staker uses the same funds to stake ETH-new. Say, for example, that I mixed ETH-new, and then staked those.
True; mixing and putting the coins back in for the same amount of stake should work. I think the slashing mechanic only works if you just don't move the funds and keep them on both chains, verifying on both of them.
There's no identity or KYC (god forbid) attached to your stake, soo you could most definitely sell the new-ETH, buy them again (or mix them) and acquire the same amount of stake on both chains.
Well VB is on my debtor list as he owes me 2 eth. which I will never see.
So I own 1 old eth on a trezor
and I own .3 staked eth2 on coinbase.
I leave them sit
now the old the on trezor is on a virgin untouched wallet what does it become down the road.
as VB has change the rules enough that I lost track of whether I have a split coin or I am getting one or VB stole some more from me an Now owes me 2 old eth + whatever.
