What guarantees there are for what happens off-chain? Because if that is garbage, the Ethereum will store tamper-proof garbage.

- btown 5y agoThe thing off-chain is itself a blockchain, with miners incentivized to work in good faith. I imagine, though haven’t verified, that ensuring the right consensus is committed to ETH can be figured out with mutual staking orchestrated via smart contracts on both ends.
- DennisP 5y agoWith zkrollups, there's a cryptographic guarantee that the off-chain computation is valid. With optimistic rollups, there's a withdrawal delay so people have an opportunity to submit proof of fraud.
