Zksync future

zkSync allows users to cross bridges and withdraw faster than Optimistic Rollups, which require a 7-day wait. zkSync's faster, more stable performance will be critical in the future multi-Rollup era, when users will interact with multiple L2s. zkSync Era security model "guarantees 100% security in Ether" and does not rely on fraud proofs or game theory, but is based on "fundamental mathematical and cryptographic primitives" (zkproofs).In contrast to the existing ZKevm, zkSync has taken some assertive architectural choices, for example, they have decided to "manage data availability by publishing updates to the storage slots involved in each transaction".
