we understand that you detected fraud within the 7-day dispute window but since we already finalised our rollup block per ethereum's block finality, we will decide to ignore this fraud.
yes, the adversary may have a million dollars worth of ether in their account but we simply won't let them withdraw it from our bridge.
all trades and transactions on rollups are final after ethereum block finality, crime or not.
We asked @_JonahB_ about @blknoiz06's take on rollups being the ideal infra for building specialized apps.
"@arbitrum can roll back on anything."
"The final state check that your transaction settled is when Ethereum reaches consensus on a block."
"Any rollup giving you fast confirmation is actually an illusion."
"With optimistic rollups it's even worse because it takes 7 days for the finality game, whereas ZK rollups give confirmation immediately."
@IanSNorden this isn’t to say your response is incorrect (it’s not), but the nuance of block validity vs state transition is what i'm emphasising on.
