What are Zk-Rollups? - Zero-Knowledge Proof

What are Zk-Rollups?

Zk-Rollups is defined as a layer 2 scaling solution that helps in a faster transaction process in the main blockchain (off-chain), while still recording the transaction details on the main blockchain(on-chain). By leveraging zero-knowledge proof, it ensures the transactions are valid without revealing any information.

Currently, there are 11 active zk-rollups locked with over $1 billion in total value and the popular execution methods are zkSkync, dYdX, and Starknet.

Features of Zk-Rollups

The main features of zk-rollups are validity proofs and on-chain data availability.

Validity Proofs - A cryptographic proof used to confirm the results of a calculation without revealing any details by zero-knowledge proofs. There are two types of proofs with their unique properties, they are:

• zk-SNARKs

• zk-STARKs

On-Chain Data Availability - Zkrollups ensures the important details are stored in the main blockchain while the transactions are stored safely. The general purpose of this storage is the key to the consensus mechanism. It supports a wide range of applications that can verify the transaction details in the rollups independently, and it is even compatible with Ethereum's Virtual Machine. 

How do Zk-Rollups work?

The working process of zk-Rollups involves the following steps:

• Batching Transactions: ZK-rollups start by accumulating multiple transactions into batches to enhance efficiency.

• Off-Chain Processing: These batches are then processed and validated outside the main blockchain, significantly reducing the strain on the main network.

• Cryptographic Proof Generation: Following successful processing, a cryptographic proof is created to demonstrate the validity of the entire batch without revealing individual transaction details.

• Proof Submission: This proof is then submitted to the main network for verification.

• Main Chain Verification: Nodes on the main chain meticulously verify the submitted proof, ensuring its legitimacy.

• Finalization: Upon successful verification by the main chain, all transactions within the batch are finalized and permanently recorded.

Advantages of Zero Knowledge Rollups

There are several advantages of zk-rollups, they are.

• Technological complexity

• Computational intensity

• Data availability concerns

• Technical barriers for users
