# Welcome to MemoMegrez What's MemoMegrez MemoMegrez Network is the underlying storage network of the MEMO decentralized storage system, which was officially launched on October 15, 2022. MemoMegrez is designed with a layered architecture, where critical information such as role information and smart contracts are stored on the blockchain, while other data is stored off-chain. This is done to improve the system's cost-effectiveness and processing capabilities. To achieve full decentralization, low redundancy, low energy consumption, high reliability, and high availability, MemoMegrez also introduces multiple technologies such as public verification, multi-level fault tolerance, and RAFI (Redundant Array of Flash Independent) repair mechanism. Through MemoMegrez, MEMO not only has the ability to interact with any mainstream public blockchain but also enables data storage and settlement through various transaction methods, showcasing its advanced capabilities in cross-chain interaction. As the underlying storage network of the MEMO decentralized storage system, MemoMegrez Network provides users with a secure, reliable, and highly available large-scale decentralized cloud storage solution through its unique design and technological implementation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
