On May 16th, the BSIM card (blockchain SIM card) jointly developed by Shanghai Shutu District Blockchain Research Institute and China Telecom Co., Ltd. (hereinafter referred to as China Telecom) Research Institute was released in Shanghai. Compared with the traditional SIM card, BSIM card has the characteristics of portability, high security and high performance, which will promote the innovative application and industrial ecological development of the next generation Internet (Web3.0).
"The storage space of BSIM card is 10 to 20 times larger than that of SIM card, and the computing power is improved by dozens of times, so that the public and private keys of users can be generated and stored in the card." Long Fan, dean of Shanghai Shutu District Blockchain Research Institute, said that BSIM card deeply integrates the blockchain user experience with SIM card, and uses the hardware security advantages of SIM card to protect the user’s private key. It is a safe and convenient Web3.0 user terminal entrance solution, which can make ordinary users participate in the Web3.0 world more safely and conveniently and enjoy the convenience brought by blockchain.
Under the support of blockchain, Web3.0 can guarantee the creator’s ownership and income rights of works through digital contracts, and reshape the digital production relationship that is more compatible with the productivity of digital content. However, compared with the existing second-generation Internet account system, Web3.0 also faces the problems of high user cognitive cost, high learning threshold and low conversion rate, which affects ecological development.
It is understood that a core innovation of Web3.0 is the "private key account system". Based on private key and signature, it provides a means for users to prove their identity and send instructions independently without relying on centralized platform. In this way, users can manage their digital assets independently of any platform and protect their digital rights and interests. In the world of Web3.0, users should carefully manage their private keys to prevent them from being stolen or lost, otherwise they will face the risk of identity being fraudulently used and digital assets being lost. Therefore, the next generation Internet needs a more popular private key management tool.
To meet this demand, BSIM card can reduce the risk of malicious software attacks by adopting hardware security protection technology, and can also realize the binding of digital identity and real identity through mobile phone number real-name registration system. In addition to the basic private key management and digital signature, BSIM card can also realize encrypted storage, key retrieval and other operations, and even integrate the traditional U shield function into the card.
Li Anmin, vice president of China Telecom Research Institute, said that in the next step, China Telecom will jointly promote the digital asset card BSIM in Hunan and other places, and apply it to the scenes of digital assets in the universe, digital identity authentication and Internet of Things equipment collection.
Focusing on the deployment of innovation chain in the industrial chain, Yip Wong, deputy director of Shanghai Science and Technology Commission, said that Shanghai will promote the integration and development of the underlying technology of blockchain, privacy computing and digital identity technology, build a technical support system for innovative applications of Web3.0, and form a new generation of blockchain innovation ecology with global influence.
