Verizon has developed a virtual SIM card on the blockchain

Telecommunications company Verizon has patented the technology of virtual SIM cards with cryptographic protection on the blockchain, which can completely replace physical counterparts.

As described in the patent application, a user account is created on a mobile device using special software, which allowsStore one or more vSIMs and bind different network services of your choice to them.After that, the phone creates a record in the blockchain, including a virtual SIM card certificate and an IMSI numberFor internationalsubscriber identity. Next, the vSIM certificate is tied to the account and can be activated.

The nodes involved in the network keep records of records andform a distributed consistent network, which Verizon calls the vSIM blockchain. All transactions have timestamps and are stored in blocks encrypted with cryptography, which protects the system from third-party interference.

The vSIM blockchain will have a hash tree structure forensure efficiency, prevent given damage and change it. Thanks to this, vSIM can be moved and assigned to any of the mobile devices associated with the account, or transferred to other users.

The operator will be responsible for backing up all data and the API set.

Digital technologies are rapidly taking root in all aspects of our lives, for example, in Brazil they have already begun to issue blockchain birth certificates.
