To address this, the community chose a rollup-centric approach. The idea is simple: Instead of hosting all applications on Ethereum, the focus is on rollups that offer faster, cheaper transactions while still settling back on Ethereum. As a result, you get faster, cheaper transactions, but still keep Ethereum’s security.

Based rollups use Ethereum for everything from ordering transactions to settling them. While this approach may not seem radically different from traditional rollups, it fundamentally shifts how sequencing is handled . Instead of relying solely on separate sequencers, based rollups leverage Ethereum itself for transaction sequencing.

Since the advent of Optimistic Rollups (ORUs) and Zk-Rollups (ZRUs), the paradigm has changed.Computation is run off-chain by high-end machines (the provers) while posting a fraud proof (on ORUs) or a validity proof (on ZRUs) on a settlement chain, which can prove the computation integrity, or in other words, that the computation has been executed ...
