• Conflux Network and China Telecom have jointly developed the world’s first Blockchain SIM card (BSIM)
• The BSIM card has storage space 10-20 times larger than traditional SIM cards and computing power several dozen times greater.
• The BSIM card can generate and store users’ public and private keys within the card, reducing risk of attacks.

Conflux and China Telecom Launches World’s First Blockchain SIM Card

Conflux Network, a regulatory compliant public blockchain in China, together with global communications network, China Telecom, recently unveiled their jointly developed Blockchain SIM (BSIM) card at the Xuhui District West Bank Artificial Intelligence Center in Shanghai.

Functionalities

The BSIM card can perform digital signatures in a “private key never leaves the card” manner which reduces risk of malware or virus software attacks targeting users‘ mobile terminals. It also offers encrypted storage, key recovery functions and even integrates traditional U-shield functions for protecting private keys.

First On-Chain Interaction Demonstrated

At the launch event, Dr Wu Ming from Conflux successfully transferred a commemorative NFT (Non Fungible Token) from Shanghai Conflux Research Institute to China Telecom by pressing send on an app powered by the BSIM Card This marks its first public use on chain to demonstrate its capabilities.

Conclusion

Dr Wu Ming stated that this breakthrough would make it easier for all mobile communication users to obtain a secure digital identity through their mobile terminals while accessing Web3 and metaverse without much technical barriers needed as blockchain technology evolves into a practical infrastructure for applications in global economy and people’s daily lives Li Anmin from China Telecom Group added that they are committed to working alongside Conflux Network in promoting practical communication technologies.
