Take sum hardware wallet as an example. The invention has that beneficial effect that:
First, the private key seed is encrypted layer by layer, physically isolated, and never touches the net.
First, when creating a wallet, the generated seed password is stored in the local encryption chip, and the 10 payment password is set forcibly.
Then, a transaction is formed in the wallet. At this point, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, physically isolated, never touching the Internet, so I don't have to worry about my password being stolen by hackers.
Second, the banking system verifies the financial motherboard and encryption chip.
The banking system is used to verify the financial motherboard, and the private key seed is stored in the chip. If the product is stolen or lost and destroyed by malicious violence, the self-destruction circuit inside the chip will be triggered, and all information in this area will be deleted immediately and permanently.
Third, it is convenient and fast to support global bitcoin ATM withdrawals.
The reason why digital assets attract the attention of many fields around the world is that it is creating a global rapid circulation. The larger the circulation field, the wider the scope and the higher the use value. The core of digital assets is the media it acts on the currencies of various countries. Moreover, there are several mainstream exchanges in the world built into the wallet, so you can trade digital assets anytime and anywhere, and you can travel around the world without worrying about changing foreign currencies.
Fourth, many * * * have signature management assets.
Different from the conventional digital wallet, multi-signature wallet needs the authorization of multiple key holders to transfer digital currency, so sum wallet is more secure. Ordinary wallet: A wants to transfer X bitcoin, and A only needs his own signature (using the private key) to complete the transaction. Sum wallet: A wants to transfer a bitcoin to X, and has set up multi-signature verification (at least two people in ABC3 need to sign to transfer money), so A needs B or C to complete the signature (using the private key) when he wants to transfer money to X, hoping to help you. thank you
