What types of rollups are there? How do ZK-rollups and optimistic rollups work? This video is a logical continuation of DeFi Teller's explainer about what rollups are, how they work, and the importance of rollups for DeFi apps. The video introduction to rollups, the most popular layer-2 scaling solution for Ethereum and other layer-1 networks, concludes with an open-ended question about how rollups validate transactions - distinguishing correct from malicious. In this video, viewers will find the answer to this question. It details the process of transaction validation and the difference between how the two types of rollups interact with the Ethereum blockchain, as well as the advantages and limitations of both. In this video, you will also learn about the difference in the practical application of optimistic and ZK rollup solutions for decentralized applications and more.

This rollups video guide covers what rollups are, why they are needed, and how they work. The video takes Ethereum rollups as an example.
Practical problems the Ethereum blockchain has faced, namely low speed and high gas fees, have led to a variety of solutions, either based on Ethereum (Layer 2) or outside of it. In this video, viewers dive into the technology of Ethereum's main Layer 2 (or L2) scaling solution and learn what tools rollup projects use to achieve scalability and high speed for DeFi apps. This video on rollups succinctly explains the essence of the technology, moving away from standard boilerplate explanations and delving into the heart of cutting-edge DeFi technology.

To tackle this problem, the search for the ultimate scaling solution has been one of the top priorities for multiple teams and the Ethereum community as a whole.

In general, there are 3 main ways to scale Ethereum or in fact, most other blockchains: scaling the blockchain itself-layer 1 scaling; building on top of layer 1-layer 2 scaling and building on the side of layer 1 - sidechains.

When it comes to layer 1, Eth2 is the chosen solution for scaling the Ethereum blockchain. Eth2 refers to a set of interconnected changes such as the migration to Proof-of-Stake (PoS), merging the state of the Proof-of-Work (PoW) blockchain into the new PoS chain and sharding.

Sharding, in particular, can dramatically increase the throughput of the Ethereum network, especially when combined with rollups.

When it comes to scaling outside of layer 1, multiple different scaling solutions have been tried with some mixed results.

On the one hand, we have layer 2 solutions such as Channels that are fully secured by Ethereum but work well only for a specific set of applications

Sidechains, on the other hand, are usually EVM-compatible and can scale general-purpose applications. The main drawback they are less secure than layer 2 solutions by not relying on the security of Ethereum and instead having their own consensus models.

Most rollups aim at achieving the best of these 2 worlds by creating a general-purpose scaling solution while still fully relying on the security of Ethereum

This is the holy grail of scaling as it allows for deploying all of the existing smart contracts present on Ethereum to a rollup with little or no changes while not sacrificing security

No wonder rollups are probably the most anticipated scaling solution of them all.

Blut what are rollups in the first place?
