Babbitt reported on the 8th, November 8th, 2019 World Blockchain Conference·Wuzhen officially opened at Wuzhen Internet International Convention and Exhibition Center. In the afternoon “Technology Unbounded: Blockchain Underlying Infrastructure” sub-forum, YottaChain founder Wang Donglin said that data storage is the best application scenario for blockchain transformation in the real economy, and decentralized storage systems are distributed globally. Thousands of stored nodes form a unified shared storage pool, and the blockchain is only used to motivate accounting and not save data. He also pointed out that storage technology has been developing along the technical path of "increasing redundancy and fault domain isolation to improve reliability" for decades. Decentralized storage is an inevitable trend in the development of storage technology. In the era of big data, people can meet the higher requirements for data storage capacity and data persistence.
