Worldcoin

Overview

Worldcoin is a decentralized identity and financial network designed to provide a unique digital identity through iris-scanning technology. This digitial ID, World ID authenticates "proof of humanness" by using zk-SNARKs to ensure privacy and security, allowing users to verify their identity without revealing personal information. The Worldcoin Dune query can be found here.

Query Structure

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

Verifier Contracts

• Size 100 Register Verifier

• Size 600 Register Verifier

• Size 1200 Register Verifier

• Size 10 Delete Verifier

• Size 100 Delete Verifier

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:

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

  • 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
