As a meta-level handling finances of many many chains, obviously its hash-power needs to be more than half as much as the total hash-power of all the chains that it serves combined, so that it would take at least a quarter of all the hashing power of all the chains that it purports to be "meta" to aka "above" to PWN it.
However, at the same time, if its hash power is more than half the hash power of any one of the chains that it deals with, then its miners could be tempted to PWN that other chain instead of mining this one.
So it also needs to not be less than half as much hashing power as any one of the chains that it serves.
So basically it seems to need to be merged mined alongside all of the chains that it serves, so that the same hashing power can secure all of them all at once...
Which is awesome because it provides all the chains of its hashing-type that have not yet enabled the ability to be merged mined as a secondary chain to do so - their incentive being that if they do, then they can participate in this distributed exchange...
However that is kinf of wishful thinking, since actually all the chaisn of its hashing-type are potential attackers whether they participate in the distributed exchange or not.
So really it does not merely need at least enough hashing power that all chains it serves cannot gang up to PWN it, it needs enough hashing power that all the hashing power of all the chains of its hashing-type, whether they participate in the exchange or not, cannot PWN it...
It is very sensible not to have it be an scrypt coin because already there are far too many scrypt coins for any but one single one of them to be able to have more than half the total scrypt hashing power that exists, thus already all, or possibly maybe all but one, of the scrypt coins already have less than half of the scrypt hashing power so all of them or possibly, maybe, there might be or might someday come to be one among them all that is not already less than 50% of the scrypt hashing power.
So basically all, or maybe if we are lucky or someday in the future all but one, of the scrypt coins are already way the heck too insecure to be trusted for any serious use...
