Scroll

Overview

Scroll is a ZK rollup that posts transaction data to Ethereum using a verifier contract to validate ZK proofs. The current verifier can be found here. The Scroll Dune query can be found here.

Query Structure

The query filters traces sent from one of the Scroll Batch Finalizer contracts (previous, current) to one of the verifier contracts (ScrollVerifierV0, ScrollVerifierV1, ScrollVerifierV2).

Calculations

• The proof volume is the number of invocations of the verifier contracts

• The cost is calculated using the following formula:

  • $\text{cost} = \sum_{\text{traces}} \left( \text{gas\_used} \times \text{gas\_price} \times \text{eth\_price} \right)$

  • Where:

    • $\text{gas\_used}$ is the amount of gas consumed by a trace in one of the verifiers

    • $\text{gas\_price}$ is the price of gas on the day of the transaction

    • $\text{eth\_price}$ is the average price of ETH in USD on the day of the transaction
