[Cryptography] Delaware allows blockchain stock registry

[John Levine]

This piece showed up today, about a change in Delaware law that allows
corporations to keep their stock register on a blockchain.  Since
Delware is the most popular US state to incorporate, I expect we'll be
seeing a few.

It notes:

" ... only the possessor of the correct cryptographic key can deal
with the shares and assign them to a third party. Once the third party
is registered as owner, then only that third party can subsequently
deal with them. And so on."

I wonder what happens when you lose your key.  You can never sell your
shares?
