- If an item has been sent by the comment author to the top-level post owner to relay on

to the rest of the contacts on the top-level post, the top-level post owner should check
|

the author_signature, then create a parent_author_signature before relaying the comment on

|
- If an item has been relayed on by the top-level post owner, the contacts who receive it
|
|
check only the parent_author_signature. Basically, they trust that the top-level post
|
|
owner has already verified the authenticity of anything he/she sends out
|
|
- In either case, the signature that get checked is the signature created by the person

who sent the salmon

- If an item has been sent by the like author to the top-level post owner to relay on

the author_signature, then create a parent_author_signature before relaying the like on

- If an item has been relayed on by the top-level post owner, the contacts who receive it

check only the parent_author_signature. Basically, they trust that the top-level post
|
|
owner has already verified the authenticity of anything he/she sends out
|
|
- In either case, the signature that get checked is the signature created by the person

who sent the salmon

- If an item has been sent by the item author to the top-level post owner to relay on
|
|
to the rest of the contacts on the top-level post, the top-level post owner checks
|
|
the author_signature, then creates a parent_author_signature before relaying the item on
|
|
- If an item has been relayed on by the top-level post owner, the contacts who receive it
|
|
check only the parent_author_signature. Basically, they trust that the top-level post
|
|
owner has already verified the authenticity of anything he/she sends out
|
|
- In either case, the signature that get checked is the signature created by the person
|

who sent the salmon
