Linea

Overview

Linea 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 Linea Dune query can be found here.

Query Structure

The query filters traces sent to the Linea L1 Message Service contract that invoke finalizeBlocks, finalizeBlocksWithProof, or finalizeCompressedBlocksWithProof and interacts with one of the verifier contracts.

Calculations

• The proof volume is the number of function calls that interact with the verifiers

• 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
