Introduction of rollups Rollups

There are various types of rollup protocols that have been developed to scale open contracts on Ethereum, the largest active blockchain with smart contracts. Rollup has become one of the scalable solutions for smart contract-based blockchain applications. This is because they save computing and storage resources by putting multiple pieces of data related to the execution of smart contracts into a cryptographically hashed transaction.

There are two main types of roll ups. These are Optimistic rollup and zero knowledge rollup. zk-rollup do the calculations before sending the credential to the chain. However, Optimistic rollup assumes transaction validity by default. It is only when the consensus is challenged that calculations are performed when using Optimistic rollup.

Arbitrage rollup is based on Optimistic rollup. However, Arbitrom's rollup technology is more advanced than other rollup chains and very little data is stored on the chain. Arbitrum Rollup also works with all Ethereum developer tools and fully supports Ethereum EVM smart contracts. Arbitrum is built on top of Ethereum and supports the same Remote Procedure Call or RPC interface. Arbitrum is also designed to be a faster and more cost-effective way to build decentralized applications. In addition, this is while maintaining the security of the Ethereum network.
