That description sounds like exactly what I have in mind for the

One aspect I have not mentioned: To discover people's reputations, you
use up untrusted IOUs by storing pseudo random gibberish on their systems.
If you only use trusted IOUs, and never grant services to entities
supplying untrusted IOUs, you will never have enough trust. To generate
trust, needs to be quite a lot low value nonsense faithfully and
reliably stored on the system, a certain substantial amount of wasted
activity in tests of trust and generation of trust.
The system as I originally described it would deadlock for lack of
trust, and would with perfect efficiency and reliability do absolutely
nothing.

I think that the reason why you can't find this filesystem is akin to the
reason
why all-powerful, all-knowing, and all-good god has not been spotted yet.
Here is a solution:
Everyone is, as with Bitcoin, identified by a public key - but by quite a
few public keys, providing not anonymity but pseudonymity.
When you store stuff on someone else's system you issue an IOU, which IOU
is anonymously transferable, using a chaumian protocol, which *does*
provide anonymity - you pseudonymously store other people's stuff, and
anonymously use the resulting IOUs to store your own stuff.
From time to time you check that stuff that is stored on someone else's
system is available by random sampling.
When stuff stored on someone else's system becomes inaccessible, you note
him as unreliable, and thus decline to issue IOUs or services to him in
future, though since IOUs are transferable, you are still up for any IOUs
you have issued to him in the past.
The software attempts to cancel out IOUs - so that if Bob provides
services to Carol, Carol provides services to Edwards, and Edwards provides
services to Bob, they cancel out. If someone's IOUs get cancelled out in a
cycle of IOUs that include your own, or include those you have confidence
are reliable, this is evidence he is reliable in that his IOUs are good.
You try to store stuff with those that you have reason to believe are
reliable, and with those where storing stuff with them enables you to
cancel out IOUs.
You give low priority to storing stuff from people whose IOUs you have no
reason to believe.
Repeating: You pseudonymously store other people's stuff, using a nym that
gains reputation thereby, and anonymously store your stuff on other
people's systems, using a nym with no reputation.
