Smarter, Safer, Larger Storage: Conflux and China Telecom Launch the World’s First Blockchain SIM Card

Shanghai’s Xuhui District West Bank Artificial Intelligence Centre was the site of today’s unveiling of the Blockchain SIM (BSIM) card, a collaboration between Conflux Network, China’s first regulatory-compliant public blockchain, and China Telecom.  The BSIM card is the first BSIM of its kind in the world, a blockchain-powered mobile user ID. The BSIM card will first be tested in Hong Kong, and then it will be rolled out to China Mainland and other international markets.

Features of the world’s first blockchain SIM card

The BSIM card, which looks quite similar to standard SIM cards, is compatible with all major mobile operating systems. The card has all the capabilities of a standard SIM card, plus the added bonus of being able to generate and store users’ public and private keys.

The BSIM card has a memory capacity 10–20 times higher and a processing power several dozen times greater than regular SIM cards. Users’ mobile terminals are less likely to be infected by malicious software when digital signatures are performed in a “private key never leaves the card” fashion, as is the case with the card.

The BSIM card also has conventional U-shield features, such as secured storage and key recovery. Protecting users’ private keys by utilising the BSIM card’s superior hardware security. It’s the most secure and hassle-free way for Web3 terminal users to log in at the moment.

During the launch, Conflux Network CTO and Co-Founder Dr. Wu Ming sent a Commemorative NFT of the China Telecom and Conflux Partnership via the app. The NFT was moved from Shanghai Conflux Research Institute’s BSIM card account to China Telecom’s BSIM card account, marking the first on-chain, public use of the BSIM card.  

According to Lin Anmin, the Deputy Dean of China Telecom Group’s Research Institute, the BSIM card is only the beginning. As a result of blockchain technology’s flexible and adaptable nature, the two companies will work together to investigate a wide variety of use cases and complementary offerings.
