China Is Gearing Up To Leverage Blockchain Technology For The Authentication Of Its Citizens' ID

Updated: Feb 29

China has introduced RealDID, a groundbreaking initiative employing blockchain technology to authenticate the identities of its 1.4 billion citizens.


Spearheaded by China's Ministry of Public Security in collaboration with the Blockchain-based Service Network (BSN), RealDID enables users to register and log in to websites without disclosing personal information, utilizing Decentralized Identity (DID) addresses and private keys to maintain a clear separation between business data and personal details.

In contrast to China's social media platforms, where influential content creators with significant followings must disclose their real names to enhance credibility and public oversight, RealDID offers a unique approach to identity verification. Notably, it stands as the world's first national-level real-name decentralized identity system, according to BSN. BSN China, managed by the National Information Center, China Mobile, and China UnionPay, oversees domestic operations, while BSN Global handles international endeavors.

Meanwhile, in the United States, a bipartisan bill has been proposed, suggesting the prohibition of federal officials from utilizing China-made blockchains, such as iFinex, the parent company of Tether, citing national security concerns. Despite recent tensions, the U.S. has taken steps to collaborate with China in addressing fentanyl trafficking, removing China's Institute of Forensic Science from a trade sanctions list.

Concurrently, China has issued warnings to its chemical manufacturers about producing fentanyl precursors, following a circular from the National Narcotics Control Commission highlighting the risks associated with the reach of foreign law enforcement.

This move comes despite ongoing human rights concerns in China, illustrating the complex dynamics between global security measures and collaborative efforts in specific areas.
