How Worldcoin is Stored

Worldcoin is a blockchain that aims to create a global identity system to enable every human on the planet to access digital services. The Worldcoin blockchain is designed to be secure, scalable, and affordable.

1. Storing User Data on the Blockchain

Worldcoin uses a novel data storage technique called "Orb". Orb is a decentralized storage system that uses a distributed network of computers to store data. This makes the data stored on Worldcoin very secure, as it is not stored in a single location.

Orb is also very scalable, which means it can store large amounts of data without any performance issues. This is important for Worldcoin, as it plans to store the identity data of billions of people.

2. Using Proof-of-Person to Verify User Identities

Worldcoin uses a Proof-of-Person (PoP) protocol to verify user identities. PoP is a decentralized protocol that allows users to prove their identity without having to share any personal information.

The PoP protocol works by using a series of challenges to verify that a user is a real person. These challenges include things like taking a photo of yourself, saying a specific phrase, and moving your head around.

Once a user has completed the PoP challenges, they are issued a Worldcoin ID. This ID can be used to access digital services and to prove their identity to other people.

3. Protecting User Privacy

Worldcoin is committed to protecting user privacy. The Orb storage system is designed to be privacy-preserving, and the PoP protocol does not require users to share any personal information.

In addition, Worldcoin uses a number of other privacy-enhancing technologies, such as:

• Zero-knowledge proofs: These proofs allow users to prove their identity without revealing any personal information.
• Homomorphic encryption: This type of encryption allows data to be processed while it is still encrypted. This means that Worldcoin can process user data without ever decrypting it.
• Differential privacy: This technique is used to add noise to data, which makes it difficult to identify individual users.

4. Making Worldcoin Accessible to Everyone

Worldcoin is designed to be accessible to everyone on the planet. The Orb storage system is designed to be low-cost and efficient, and the PoP protocol is designed to be easy to use.

In addition, Worldcoin is working with a number of partners to make sure that everyone has access to the technology. These partners include:

• Governments: Worldcoin is working with governments around the world to issue Worldcoin IDs to their citizens.
• Non-profit organizations: Worldcoin is working with non-profit organizations to provide Worldcoin IDs to people who do not have access to government-issued IDs.
• Businesses: Worldcoin is working with businesses to incorporate Worldcoin IDs into their products and services.

Conclusion

Worldcoin is a blockchain that is designed to create a global identity system. The Worldcoin blockchain is secure, scalable, and affordable. Worldcoin also uses a number of privacy-enhancing technologies to protect user data.
