blockchain rollups

Rollups blockchain is an extension of layer 2 technology in the blockchain ecosystem, aimed at improving scalability, efficiency, and transaction security.

What are Rollups?

Rollups are a type of scalability solution that offloads transaction burdens from the main chain (or layer 1) to dedicated sidechains (layer 2). This allows for increased network throughput, reduced transaction fees, and improved system performance.

Types of Rollups

There are two main types of Rollups: contract-based Rollups (zk-Rollups) and data-optimized Rollups (Optimistic Rollups).

Zk-Rollups

Zk-Rollups utilize zero-knowledge proofs to aggregate transactions off-chain, enabling the verification of transaction correctness without the need for their actual execution. This saves time and costs required for transaction verification on the blockchain.

Optimistic Rollups

Optimistic Rollups operate on the principle of “optimistic assumption” – assuming transaction correctness until proven otherwise. This saves time and resources as most transactions are processed quickly, with only disputed ones being verified on the main chain.

Advantages of Rollups blockchain

Implementing Rollups in the blockchain ecosystem brings many benefits, such as increased network scalability, reduced transaction fees, optimized processing speed, improved energy efficiency, and enhanced data security.

With Rollups technology, it is possible to effectively address performance and transaction cost issues in blockchain, making it an increasingly attractive solution in the field of crypto assets.
