Rollups

We have learnt that Rollups are an off-chain scaling method, but what exactly are they, and what kinds of them exist? They are viewed as one of the most promising scaling solutions for public chains because:

Transaction-per-Second without making severe trade-offs
Scalability
Leverage main-chain security

Rollups handle transactions off-chain like Plasma and Sidechains; however, they post transactional data on the main chain. To decrease on-chain storage, rollups bundle transactions and compress them before sending them to the main chain. Thus, the data posted on the main chain is significantly reduced, increasing the overall network resource efficiency and scalability. Moreover, rollups rely on the main chain's security, considering that smart contracts are deployed on the main chain. Users can interact with the rollups through the rollup smart contract, which lives on the main chain.

To date, two types of rollups exist, Zero Knowledge and Optimistic rollups. Be sure to stick around for the coming days to learn about them!
