# Model
|
||
|
|
|

|
|
A reasonable mental model of Tilde Friends is as a virtual computer. User
|
||
|
|
interace is through a web browser. Communication with the outside world is
|
||
|
|
through the Secure Scuttlebutt (SSB) network protocol. Persistence is through
|
||
|
|
an SSB store and an additional key-value store in an sqlite database.
|
||
|
|
|
||
|
|
The schema for the sqlite database is primarily a `messages` table and a
|
||
|
|
`blobs` table, which are what one would expect from the SSB specifications.

digraph {
