@trishalynnTrisha Lynn 🇵🇭 🇺🇸 🇨🇦 If the user is online when the data is received, there may be no time between the time the data is received and when the user reads it.
However, most users aren't online most of the time. There's a strong chance that there are minutes, hours, or days between when the data is received and when it is read.
@trishalynnTrisha Lynn 🇵🇭 🇺🇸 🇨🇦 Most ActivityPub implementations today lean waaaaaay into the early part of this gap -- verifying the data as soon as it is received.
The problem with this is that sometimes hundreds or even thousands of servers receive the data within a few seconds -- and if they all verify the data with the third-party server immediately, it can swamp that server with requests.
