The Mesh is essentially a per-user central database + a bunch of protocols
based on cryptography, right? There's an initial "entity declaration"
(database object?) containing sub-entries like basic profile data and the
public key, as well as Mesh specific policy rules.
Given the blockchain style checkpointing and one authoritive source of
events (each update must be signed by a trusted key), all entries are
protected from manipulation.
If it was Git we were talking about, we'd just be talking about file paths.
I don't know what terminology is used for transparency logs. In Factom
there's "proof-of-process" that can be applied to an individual document to
prove it isn't being forked when updated.
So, you want a name for the non-static entries belonging to some given
user's Mesh profile? And you want to produce some static identifier from
this...? (Your question isn't actually entirely clear)
I suggest something as simple as "Mesh entry" as the name, and "Mesh entry
ID" as the fingerprint equivalent, with the value derived from the initial
entry value + probably the hash of the initial "genesis block", or "Mesh
root", for that user (to guarantee it is unique).
