Overview

World (formerly Worldcoin) is a decentralized identity and financial network designed to provide a unique digital identity through iris-scanning technology. This digital ID, World ID authenticates "proof of humanness" by using ZK proofs to ensure privacy and security, allowing users to verify their identity without revealing personal information. The data collected is from the Semaphore Merkle Tree Batcher, which adds and deletes users from the Identity manager. The World Dune query can be found .

Query Structure

The query filters transactions sent to the WorldIDIdentityManager that invoke verifyProof or verifyCompressedProof on one of the verifier contracts.

Verifier Contracts

Calculations

  • The proof volume is the number of traces that invoke verifyProof or verifyCompressedProof on one of the verifier contracts

  • The cost is calculated using the following formula:

    • cost=∑traces(gas_used×gas_price×eth_price) \text{cost} = \sum_{\text{traces}} \left( \text{gas\_used} \times \text{gas\_price} \times \text{eth\_price} \right) cost=∑traces​(gas_used×gas_price×eth_price)

    • Where:

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

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

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