all the DeFi metrics on @base today will pale in comparison to what big players will bring once they feel safe and confident about the security considerations enabled by fault proofs.

For the small brains out there (me), are fault proofs the ability for any user to contest the 'optimistically' confirmed state of the chain? Or something different entirely?

ser, you just gave a big brain definition right there. yep, fault proofs are the vehicle for contesting “optimistically” confirmed state, when need be.

Ok, sick! I wanted to make sure I had my head wrapped around it. So there's some sort of cryptographic math that can be done to prove that there's an error? If there is one, would they have to roll back the chain or something? Never really got that

it ideally will involve serious cryptography work to streamline most of the process and save cost. naively, there’ll be a ton of re-execution(which is costly). yep, the finding of an illegal/dishonest state transition will result in a rollback of the effects of said state transition.

Ah, gotchya! So it just rolls back the state that was wrongly changed - and hopefully it's not a butterfly effect of other state that was impacted by the erroneous state change

well…that’s the not so fun part. theoretically speaking, if the bad state transition did influence a bunch of state in subsequent state transitions, then they all gotta…go back too 😬 (i actually wanna test this out to observe it myself)

Yikes 😅 that doesn't sound great. But at least it's only a 7 day window of state that can be altered for most L2s I think. Kinda reminds me of my shitty file naming conventions state_confirmed-final-NoForRealThisTime.doc

Up to 7 days. Bad state can be caught in minutes because of incentives so doubt we’ll see such mess(we shouldn’t)
