Worldcoin is an open-source system established by OpenAI CEO Sam Altman, aiming to verify identity and financial public goods through Blockchain technology. The project targets solving the issue of lacking legal or digitally verifiable identities for nearly 1 billion individuals globally, especially in developing countries. Additionally, it seeks to address the lack of banking access for over 1.7 billion adults, particularly in rural areas. The system comprises three main components: World ID, World App, and WLD coin.
What Is Worldcoin?
World ID is a decentralized and privacy-preserving identity solution enabling users to prove their uniqueness and prevent the misuse of Worldcoin services by bots. It is designed for citizens in developing countries lacking proper forms of identification. Data stored in World ID is protected with zero-knowledge technology, ensuring verification without revealing real identities or online habits.
World App serves as a mobile application linked to the user’s World ID. It acts as a cryptocurrency wallet, supporting wallet features such as sending and receiving tokens, and buying and selling tokens. The app also provides access to Worldcoin grants and time-limited payments in WLD for verified users in eligible countries. During its beta phase, World App attracted over 1.5 million users.
WLD coin is the currency used for Worldcoin grants and governance over the protocol. It has a maximum supply of 10 billion and is listed on various cryptocurrency exchanges, including Binance.
The identity verification process of Worldcoin involves using a biometric imaging device called Orb to capture iris patterns. Orb is utilized by Worldcoin Operators to verify users in person, making World ID resistant to fraudulent identities.
While aiming to increase accessibility to the global economy and financial services, Worldcoin has faced criticism regarding its privacy implications and tokenomics. Privacy advocates and former Ethereum 
$2,318 developer Hudson Jameson raised concerns about the Orb verification method and the lack of transparency in the project.
Despite criticisms, Worldcoin has received significant investments, including $100 million in a Series A round from investors such as a16z, Digital Currency Group, and Coinbase Ventures.
Where to Buy WLD Coin?
WLD coin can be securely bought and sold on Binance, the world’s largest cryptocurrency exchange by trading volume. At the time of this writing, WLD coin is traded on Binance under the WLD/BTC and WLD/USDT pairs.
To purchase WLD coin, users must first sign up for Binance (if not already registered). Once registration is complete, fiat money such as Turkish lira or cryptocurrency should be transferred to the Binance wallet. After completing the transfer, WLD coin can be purchased through the two pairs mentioned above.
To buy through the WLD/USDT pair, users should navigate to the interface of this pair. In the limit section of the interface, the desired amount to purchase is entered. After entering the amount, the purchase is finalized with the Buy WLD order.
