Blockchain Sector

by Li Zhuoxi

According to a white paper released by the Information Center of the Ministry of Industry and Information Technology on May 20， 2018， a complete industrial chain for the blockchain sector has emerged in China and developed rapidly.

Blockchain is a decentralized and distributed ledger database. In a transaction supported by the blockchain technology， buyers and sellers can make the deal directly without any intermediary platform. After the deal， the system broadcasts the transaction information， and all computers that received the information record the deal after confirmation， which means that all computers involved would backup for the deal. Therefore， this kind of data storage system is transparent， traceable， unhackable and safe.

By the end of March 2018， the number of blockchain tech companies in China had reached 456. Most， as much as 80 percent of the total， are concentrated in Beijing， Shanghai， Guangdong and Zhejiang. Their operations range from hardware manufacturing， platform services and security services to technological application services， investment， media and human resources services.？
