Worldcoin Whitepaper Explanation

#201

Worldcoin aims to create a globally-inclusive identity and financial network by utilizing a proof of personhood system to distinguish humans from AI while preserving privacy.

Worldcoin Introduction

Worldcoin is a pioneering project with a mission to build a globally-inclusive identity and financial network. The project's goal is to create a reliable solution for distinguishing humans from AI online, while preserving user privacy. By providing a digital identity (World ID) and a digital currency (WLD), Worldcoin aims to increase economic opportunities, enable global democratic processes, and potentially pave the way for AI-funded universal basic income (UBI).

The project addresses the growing challenge of distinguishing humans from increasingly sophisticated AI bots. Worldcoin introduces a unique proof of personhood mechanism using biometric verification through a custom device called the Orb. This approach ensures that every human can have a World ID and receive WLD tokens simply for being human, making it a novel solution to a pressing global problem.

Description: What Does Worldcoin Do?

Worldcoin's primary objective is to create a globally-inclusive identity and financial network. The project is designed to increase economic opportunity, provide a reliable method for distinguishing humans from AI online, enable global democratic processes, and explore the potential for AI-funded universal basic income (UBI).

To achieve these objectives, Worldcoin has introduced a digital identity network called World ID, which uses custom biometric hardware (the Orb) for proof of personhood. The network issues a digital currency (WLD) to verified users, aligning incentives for network growth and participation. The World App serves as the first frontend interface for users to interact with World ID and the Worldcoin protocol.

Problem: Why Worldcoin Is Being Developed?

Worldcoin is being developed to solve the pressing problem of distinguishing humans from increasingly advanced AI bots. This issue is critical for fair participation in digital spaces, secure online voting, and equitable distribution of resources. The lack of a scalable and inclusive proof of personhood has made it difficult to address these challenges on a global scale.

Existing solutions for identity verification are limited in scope, often invasive to privacy, and not scalable to a global population. Worldcoin's approach using biometric verification through the Orb aims to provide a secure, privacy-preserving, and scalable solution to this problem.

Use Cases

  • Online Voting: Ensuring only real humans participate in digital democratic processes.
  • Airdrops and Token Distribution: Fair distribution of digital assets to verified humans.
  • Social Media and Online Platforms: Preventing bot attacks and ensuring genuine human interaction.

How Does Worldcoin Work?

Worldcoin consists of several key components: the World ID, the Orb, the World App, and the WLD token.

  • World ID: A privacy-preserving digital identity that verifies a user's humanness and uniqueness.
  • Orb: A custom biometric device that verifies users' identities through iris scans.
  • World App: The first wallet app that supports World ID, guiding users through verification and managing credentials.
  • WLD Token: A digital currency issued to verified users to incentivize network growth.

To use Worldcoin:

  1. Download the World App: Users download the World App to start the process.
  2. Visit an Orb: Users visit a physical Orb device to get their identity verified through an iris scan.
  3. Receive World ID: Upon successful verification, users receive a World ID.
  4. Claim WLD Tokens: Verified users can claim WLD tokens through the World App.

Technical Details

Worldcoin utilizes a combination of blockchain technology and biometric verification. The project is built on the Ethereum blockchain and uses zero-knowledge proofs to maintain privacy. The Orb device ensures secure biometric verification without storing raw biometric data.

  • Blockchain: Ethereum and Optimism
  • Consensus Mechanism: Ethereum's Proof of Stake (PoS)
  • Innovations: Custom biometric hardware (Orb), zero-knowledge proofs, integration with multiple chains for scalability.

Worldcoin Tokenomics: Token Utility & Distribution

The WLD token serves multiple purposes within the Worldcoin ecosystem. It is used to incentivize network growth, enable governance, and facilitate transactions within the ecosystem.

WLD tokens are distributed to verified users and allocated with a focus on decentralization. The initial supply cap is 10 billion WLD, with a potential inflation rate of up to 1.5% per year after 15 years, governed by the protocol.

Key Worldcoin Characteristics

Worldcoin aligns with several core blockchain characteristics:

  • Decentralization: Utilizes Ethereum's decentralized infrastructure.
  • Anonymity and Privacy: Employs zero-knowledge proofs for privacy-preserving identity verification.
  • Security: Uses biometric verification and Ethereum's security features.
  • Transparency: Publicly available Merkle tree for identity verification.
  • Immutability: Transactions and identity verifications are immutable on the blockchain.
  • Scalability: Supports multi-chain operations and scalability through Optimism and Polygon.
  • Supply Control: Fixed initial supply with controlled inflation.
  • Interoperability: Integrates with multiple blockchain networks and identity protocols.
