ZK-Rollup

In a ZK-Rollup, operator(s) must generate a succinct Zero-Knowledge Proof (SNARK) for every state transition, which is verified by the Rollup contract on the mainchain. This SNARK proves that there exists a series of transactions, correctly signed by owners, which update the account balances in the correct way, and which lead from the old Merkle root to the new one. It is thus impossible for the operators to commit an invalid or manipulated state.

A popular takeaway regarding the FTX drama has been that this was not a DeFi problem, but a TradFi one. It’s absolutely true that custody risks apply to CEXs and not DeFi. Yet, given the size of the collapse, we find it important to ask why, despite all their inherent custodial risks, CEXs continue to attract capital at such higher orders of magnitude.
