Prompt Title: ActivityPub Protocol Explainer

Q: How does ActivityPub handle inbox and outbox operations?

A: ActivityPub uses the inbox and outbox mechanisms to handle interactions between users and their activities. When a user performs an action like creating a post or following another user, the activity is stored in their outbox. When this activity needs to be delivered to other users (e.g., followers), it is sent to their respective inboxes.

Q: When I write a post on an ActivityPub platform like Mastodon, what's the flow sequence regarding inbox and outbox?

A: When you write a post on an ActivityPub platform like Mastodon, the following sequence of events happens:

1. You create a new activity (e.g., a Note) and it is stored in your outbox.
2. The platform then sends the activity to the inboxes of your followers or any other users who should receive the activity.
3. The recipients' servers process the incoming activity and store it in their respective users' inboxes.
4. The users can now view the activity in their feeds or timelines.

Here's a JSON-LD Step-By-Step guide schema for the sequence of events when writing a post on an ActivityPub platform:
