we’re not talking enough about much liquidity will be deployed on OP Stack chains like @base once fault proofs go live on mainnet.

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.

Probably doing stuff and things.

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.

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.

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
