What is the significance of the root chain RSK?

What is the significance of the root chain RSK? In Chinese, it refers to a public chain that enables the construction of decentralized systems and applications based on blockchain technology. The root chain is an open-source public internet called “Root Chain” proposed by Professor Yang Dong from the Institute of Computer Network and Information Security at the Chinese Academy of Sciences and Beijing Institute of Technology. It ensures the smooth operation of the main network by using the R key to send transactions and perform verification. Additionally, due to its features such as the adoption of the Bitcoin consensus mechanism and the Ethereum smart contract language C++, the “Root Chain” will serve as the core layer of the entire internet, supporting business logic and application functionality on the root chain, including data transfer protocols (DHT), encryption algorithms, cross-fork upgrades, and cross-ledger communication, among others.
