# Blockchain

Blockchain technology provides the underlying framework for the FOG Metaverse. Blockchain technology is known for its ability to provide a secure, decentralized, and transparent network, which is critical for any digital platform that deals with sensitive data and financial transactions. With blockchain, users can participate in a distributed network, without the need for intermediaries or third parties. This provides users with control over their data and eliminates the need for centralized entities to facilitate transactions.
