What about staking $ENS to renew a domain?
You renew a domain by staking the equivalent of 5 dollars in $ENS.
(optional, of course)
The staked $ENS goes to a ENS vault, from which you can still use it to vote, but you can’t transfer from it.
If the domain expires, the $ENS goes back to you.
- voting power is preserved
- there is no selling of $ENS
