the score is the hash of the data in the block. the same block on two
servers will have the same score (important for replication).
different blocks have the same odds of having this same score (that
is, astronomically low) regardless of whether they're on one or
multiple servers.
that doesn't directly address their suitability as UUIDs. it seems
like an odd choice to me (certainly it's an expensive way of
generating them), although i guess it depends what your application
is.
