If I’m in the queue, should I have a sentinel running? Whats the risk of being selected and not having time to set up a sentinel?
(from Booker#1170 on discord)
If your verifier is too weak it’s possible it gets down after joining the cycle. The load for incycle verifiers is much higher. The sentinel will protect your joined verifier from dropping immediately after the join.
You need atleast two verifiers for the sentinel running correctly
So the sentinel gives you time to sort performance problems out or saves you from provider issues like downtime/maintenance
