The world's first-ever "blockchain-enabled" SIM card has been revealed in Shanghai.

Known as a BSIM card, it's actually an integration of a SIM card and a bank card, providing safer and more convenient access to Web3 and Metaverse tech, the next phases in the development of the Internet.

It was developed by Conflux, a world-leading public blockchain developed by the Shanghai Tree-Graph Blockchain Research Institute, in cooperation with China Telecom, China's second-largest telecom operator with over 390 million users.

BSIM card looks pretty much the same as a traditional SIM card, but its storage space is 10 to 20 times larger, and its computing power is 10 times stronger. According to Long Fan, director of Tree-Graph, it can also reduce the risks of being maliciously attacked.

"Using a BSIM card as entry to Web3 helps to improve digital economic management," he added.

Li Anmin, deputy director of the China Telecom Research Institute, said the company plans to promote the use of BSIM cards in digital identification certification, Internet of Things, Metaverse assets management and other applications.
