The Merge on Ethereum will transition the network to Proof-of-Stake. Some stakeholders intend to fork the network to maintain one (or more) Proof-of-work chain(s).
When this happens, the mutual's assets will be duplicated on these other chains.
This vote will act as a temperature check to see if the community is willing to sell these duplicated assets and grant a 3rd party ( most likely someone from the Advisory Board) the ability to send them to a centralized exchange for execution.
If the vote is approved, there will be a follow-up vote on-chain, with multiples options regarding what to do with the proceeds.
