[CS198.2x Week 1] Practical Byzantine Fault Tolerance

[@aoe9857]

The example only demonstrates crash tolerance, not byzantine fault tolerance

[@Joe4740]

Very well explained. Thank you so much! 🙌

[@ThisIsAli_Off]

I do not understand something, at 3:35, we can see that Rustie and Gloria have received only 1 prepare message < 2f = 2 . So why do they commit? Shouldn't Derrick be the only one committing as he's the only one who received 2 prepare ?

[@Brc240]

Same question. Did you figure it out? If so could you explain to me

[@vitorschroederdosanjos6539]

Prepare and pre-prepare are counted together

[@Skandar0007]

Probably to avoid loop

[@DaniloFaria7]

That's because the pre-prepare from the primary node Derrick also counts as one vote in this stage.

[@plamenmanov2694]

Great explained!

Thank you for this video. Very Well explained. One query: in this entire explanation, Nadir node looks more like a faulty node than a byzantine node. Can you explain the difference and why Nadir is assumed to be non-existent rather than sending out varying messages?

[@vladanlausevic1733]

Is the difference that a faulty node can exist regardless of the system? Meaning that a faulty node can exist in both Byzantine and non-Byzantine system

[@YouTubist666]

Nice job!!

[@vladanlausevic1733]

Good, thanks for the video.

Raft isn't by default Byzantine fault tolerant
