Significance
The BSN's most immediate objective is to promote international trade by enabling smart contracts and supply chain tracing. It is often mentioned alongside other Chinese initiatives aimed at facilitating trade, most importantly the Belt and Road Initiative.
Impacts
The West will be suspicious of the BSN, and if it becomes widely adopted it could elicit some kind of pushback or attempts to counter it.
The BSN could improve the competitiveness of Chinese manufacturers by cutting costs and improving quality and security.
In conjunction with the Digital Yuan, the BSN will advance China's efforts to create a universal digital payments system.
