Conflux and China Telecom Debut First On-Chain Interaction With Blockchain SIM Card

May 16, 2023 – Toronto, Canada

Conflux Network, the first regulatory compliant public blockchain in China, and global communications network, China Telecom, today unveiled its jointly developed BSIM (blockchain SIM) card at the Xuhui District West Bank Artificial Intelligence Center in Shanghai.

In a world first, the BSIM card is a mobile user identification card based on blockchain technology.

With an appearance nearly identical to traditional SIM cards, the BSIM card is fully compatible with mainstream mobile terminal systems such as Android and iOS.

It also boasts storage space 10-20 times larger than traditional SIM cards and computing power several dozen times greater.

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 card can implement encrypted storage, key recovery functions and even integrate traditional U-shield functions.

Leveraging the hardware security advantages of the BSIM card to protect users’ private keys, it is currently the safest and most convenient Web 3.0 user terminal entry solution available.

During the launch event, Wu Ming, CTO and co-founder of Conflux Network, successfully transferred a commemorative NFT of the China Telecom and Conflux partnership by pressing the ‘send’ button within the app.

This marked the first on-chain public use of the BSIM card, as the NFT was transferred from the BSIM card account of Shanghai Conflux Research Institute to the BSIM card account of China Telecom.

Wu Ming said,

“From now on, all mobile communication users can obtain a more secure digital identity through mobile terminals and access Web 3.0 and the metaverse with minimal technical barriers.

“Blockchain technology has evolved beyond its reputation as a complex and inaccessible concept, transforming into a truly practical infrastructure for applications in the global economy and people’s daily lives.”

Li Anmin, deputy dean of the Research Institute at China Telecom Group, added,

“We are committed to working alongside Conflux Network in developing and promoting practical communication solutions tailored to meet genuine user needs.

“The BSIM card is just a first step as we collaborate in exploring a diverse…
