Worldcoin (WLD) is an ambitious cryptocurrency and global identity verification project launched in July 2023. Its mission is to create the world’s largest, privacy-preserving identity and financial network as a public utility, designed to empower individuals globally. At its core is World ID, a decentralised and privacy-focused identity system that enables users to prove their uniqueness and humanity without disclosing personal information. This is achieved using the Orb, a custom-built biometric device that scans users’ irises and generates unique identifiers in compliance with privacy standards.

Worldcoin also features the WLD token, which powers the ecosystem by serving as a medium of exchange and a governance token. In October 2024, the project transitioned from Ethereum’s Optimism network to its native World Chain, a Layer-2 blockchain built using Optimism’s OP Stack, prioritising scalability, inclusivity, and human-centric design.

1. Digital Identity Verification: Worldcoin provides an innovative solution to the challenges of online identity and human verification, addressing issues like Sybil attacks and ensuring equitable distribution of digital resources:

• World ID: Enables users to verify their humanity and uniqueness using zero-knowledge proofs, ensuring privacy while protecting against identity fraud.
• Applications: Prevents bot activity in social media, facilitates fair token distributions, and enables equitable access to digital services.

2. Financial Transactions: Worldcoin extends its utility into financial inclusion, leveraging the WLD token as a medium of exchange:

• Payments: WLD tokens are used for transactions across goods and services, both within and outside the Worldcoin ecosystem.
• Stablecoin Integration: Designed to improve financial access in regions where stablecoins play a vital role in daily transactions.
• World App: The primary wallet interface that supports cryptocurrency payments and access to decentralised applications (dApps).

3. Network Governance: The WLD token grants its holders the ability to shape the protocol through governance mechanisms. Users participate in voting and decision-making processes, influencing factors like ecosystem development, fund allocation, and potential inflation rates.

4. Human-Centric Blockchain: With the launch of World Chain, Worldcoin integrates unique features designed to prioritise its user base of verified humans:

• Priority Blockspace: World Chain allocates free or subsidised transaction space for verified users, ensuring equitable access to the blockchain network.
• Gas Allowances: Verified human addresses receive gas fee subsidies, reducing friction for casual users.

5. Ecosystem Growth and Developer Tools: Worldcoin provides infrastructure and tools to foster ecosystem expansion:

• Mini Apps and Minikit: Developer-friendly tools for building and distributing dApps tailored to verified human users.
• Grants and Support: The World Foundation offers funding for initiatives like bot-resistant platforms, decentralised governance, and Universal Basic Income (UBI) experiments.

• Anonymous On-Chain Verification: Allows users to interact with decentralised applications without revealing sensitive personal information.
• Free Transactions for Verified Users: World ID holders benefit from subsidised or free transactions, removing barriers to participation.
• Gas Redistribution Mechanism: Gas fees are optimised, with casual users receiving allowances to minimise entry costs.

World Chain also supports a growing ecosystem of blockchain services and applications, including integrations with Uniswap, Alchemy, and Dune Analytics. It features tools for developers to deploy contracts seamlessly and reach over 15 million verified users globally. The transition from Optimism’s network to World Chain marks a significant milestone in making Worldcoin a fully human-centric blockchain network.

In October 2024, Worldcoin launched World Chain, its dedicated Layer-2 blockchain built on Optimism’s OP Stack. This transition ensures scalability and prioritises verified human users with features such as:

• Anonymous Verification On-Chain: Enables users to interact with dApps without revealing their real-world identities.
• Free Transactions for Verified Users: Subsidised transactions for World ID holders to enhance accessibility.
• Gas Allowance Mechanism: Ensures equitable participation by redistributing gas fees to cover casual users’ activities.World Chain also integrates partnerships with major blockchain services, such as Uniswap, Alchemy, and Dune Analytics, further solidifying its ecosystem. With over 15 million verified users and a robust infrastructure for dApps, World Chain is positioned as a human-first blockchain solution.
