Given that the chained hash will only allow access to keys found earlier in the chain -- ie. a key 'a' in a hash later in the chain will be hidden by a key 'a' in an earlier hash -- what is the advantage of a chained hash over composing a simple hash, from the chained hashes in reverse order?

I'm just wondering (but not dismissing) the use-case?

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
