Overview
• Conflux Network and China Telecom unveiled their jointly developed Blockchain SIM (BSIM) card.
• The BSIM card is a mobile user identification card based on blockchain technology with larger storage space and computing power than traditional SIM cards.
• This marked the first public use of the BSIM card, as a Commemorative NFT was transferred from the BSIM card account of Shanghai Conflux Research Institute to the BSIM card account of China Telecom.
Appearance
The Blockchain SIM (BSIM) card has an appearance nearly identical to traditional SIM cards, but it has storage space 10-20 times larger than traditional SIM cards and computing power several dozen times greater. It is fully compatible with mainstream mobile terminal systems such as Android and iOS.
Functions
Alongside traditional communications functions, the BSIM card also can generate and store users’ public and private keys within the card. By performing digital signatures in a “private key never leaves the card” manner, the card reduces the risk of users’ mobile terminals being targeted by malware and virus software attacks. Furthermore,the BSIM can implement encrypted storage, key recovery functions and even integrate traditional U-shield functions for extra security.
Launch Event
At the launch event in Shanghai Xuhui District West Bank Artificial Intelligence Center, Dr Wu Ming from Conflux successfully transferred a Commemorative NFT of China Telecom & Conflux Partnership by pressing send button within an app using his BISM Card account from Shanghai Conflux Reseach Institute to China Telecom’s BISM Card Account – marking first on-chain public use of BISM Card.
Conclusion
Dr Wu Ming stated that mobile communication users can now obtain more secure digital identity through their mobiles terminals & access Web3/ Metaverse with minimal technical barriers – transforming blockchain technology into practical infrastructure for applications in global economy & people’s daily lives; Li Anmin from China Telecom added that they are committed to working alongside Conflux Network for developing & promoting practical communication solutions leveraging blockchain technology benefits.
