How do you control a 51% attack occurs on a Monero style blockchain?

So I was looking at Electroneum's blockchain explorer, which is a derivative off of Monero's blockchain. I'm not sure whether this is Cryptonite's properties or a Monero feature but the characteristic of this blockchain explorer is that you cannot view any of your wallet addresses from the blockchain explorer. This is by design and I have no problem with this, even though it's a pain to prove externally that your paper wallet actually has a balance in this scheme.

So given this bit of information, how do you do damage control of a 51% attack on the network? I assume that it's easy to view a 51% attack on the blockchain by looking at the transactions (could be wrong about this). But when your blockchain does not allow you to see addresses, how do you approach damage control on this blockchain style? Here you won't know who the attackers are and it's not easy to track how much was "stolen"

Contrast this to XVG where you can actually see the addresses "responsible" their 51% problem and maybe do something or at least monitor those addresses.

Any thoughts on this?
