Hi,
Today we have a funny situation, that if the (unregulated) stock exchange closes tomorrow, as happened with GLBSE, we will be holding the stock with no proof of owning it. We will lose rights for our shares.
Short term solution:
Bitfunder stock exchange has a public list of all assets held by all members / shareholders:
https://bitfunder.com/assetlist*Perhaps other exchanges have something similar.
What I recommend, is for each serious company mirror this list from all the exchanges *daily* on their own corporate servers for public to view. (like on
http://www.virtualminingcorp.com/ for ActiveMining)
Long term solution:
We must be able to store our stocks offline, off the exchange should things go wrong, in a similar way to storing our Bitcoins offline.
This is theoretically possible by using a technology called "Colored BitcoinX", which can "color" bitcoin fractions into company stocks, and store them in the block-chain.
We must convince the exchanges to adopt this standard -or- come up with a separate block-chain for storing stocks offline.
This will greatly reduce investor risk, and will let investors to invest more money.
It will also allow moving stocks between exchanges.
This is something exchanges should implement.
