## What is the Rollup of Validity Rollups?

Validity rollups, also known as ZK-rollups, are a Layer 2 scaling solution designed to increase blockchain throughput by processing transactions off-chain. These rollups bundle hundreds of transactions into a single batch and submit a cryptographic proof of validity to the main chain. This approach significantly reduces the computational burden on the Layer 1 network.

## What is the Architecture of Validity Rollups?

The architecture of a validity rollup involves a smart contract on the main chain that verifies the cryptographic proof submitted by an off-chain prover. This proof guarantees that all transactions within the batch were executed correctly according to the protocol rules. The main chain only needs to verify the proof, rather than re-executing every transaction, enabling massive scalability.

## What is the Verification of Validity Rollups?

The verification process relies on zero-knowledge proofs, which cryptographically attest to the integrity of the off-chain state transition. This mechanism ensures that the rollup's state remains consistent with the main chain's security guarantees. The high level of security provided by validity proofs makes them a preferred solution for high-value applications like derivatives trading.
