Initial cut at Zot-2012 protocol. This is a very rough draft of some very rough ideas and concepts.
|
|
It is not yet intended to be a definitive specification and many things like the security handshakes are yet to be specified precisely.
|
|
|
|
All communications are https
|
|
|
|
|
|
First create a global unique userid
|
|
|
|
|
|
Site userid:
|
|
https://macgirvin.com/1
|
|
|
|
$guuid = Strings::base64UrlEncode(hash('whirlpool','https://macgirvin.com/1.' . mt_rand(1000000,9999999),1);
|
|
|
|
|
|
Then create a hashed site destination.
|
|
|
|
$gduid = Strings::base64UrlEncode(hash('whirlpool', $guuid . 'https://macgirvin.com',1);
|
|
|
|
These two keys will identify you as a person+site pair in the future.
|
|
You will also obtain a password upon introducing yourself to a site.
|
|
This can be used to edit locations in the future. You will always keep your global unique userid
|
|
|
|
|
|
The steps to connect with somebody are to first register your location with their site.
|
|
Then introduce yourself to the person. This contains flags for the desired relationship.
|
|
At some future time, they may confirm and adjust the relationship based on their comfort level.
|
|
Lack of confirmation is tantamount to denial.
|
|
|
|
You can set either or both of FOLLOW and SHARE which indicates the relationship from your viewpoint.
|
|
They may do likewise.
|
|
|
|
A relationship is based on you as a person and provided you register new locations with the site you can post from anywhere.
|
|
You do not need to register locations with each person, only with the site.
|
|
|
|
|
|

Passing messages is done asynchronously. This may (potentially) relieve a lot of the burden of distribution from the posting site. If you're on site 'A' and make a post, site 'A' just contacts any downstream sites and informs them that there is new content (via a $post_id). The downstream site initiates the actual data transfer.
