Methodology

Overview

This project captures the amount spent in gas and the volume of proofs verified by different zero-knowledge (ZK) protocols on the Ethereum Mainnet. Where possible, the gas costs specifically associated with verification are separated from other transaction-related gas expenses.

Data Sources

Dune is used for collecting metrics for each of the projects below. The queries used are from the Nebra ZKP Verification Cost dashboard.

Calculations

The methodology used to calculate the proof volume and the associated costs follow the same format.

• The proof volume is the total number of verify or prove function calls

• The cost is calculated by summing the gas spent on these function calls
