Concerns over staking pools

[CashMeOutside]

Already we see another use case for the “read only wallet”

How about a read-only wallet; think Monero's "view key"

I see you boys are developing your light-weight wallet spec. https://github.com/input-output-hk/cardano-sl/pull/2669/files Would you consider the use case where someone wants to demonstrate an account balance to a third party? A read-only wallet if you like. Or a Monero view key, to use another ecosystem’s nomenclature. Martin wants to let Bob see how much ADA he has in his wallet - real time, all the time - how are you going to do that?

If this were possible the pool operator would publish their read-only wallet, we could all see they were delegating their own funds to the pool and how much.
