The private key serves as a user's identity proof and control in the blockchain network, and only users holding the correct private key can initiate valid transactions and obtain corresponding assets. Meanwhile, the private key also plays a crucial role in protecting user accounts from unauthorized access and preventing security breaches. Private keys must be properly stored, as once they are lost or leaked, the assets in user accounts may be at risk of theft. In blockchain networks, public keys and private keys are one-to-one correspondents; the public key can be viewed by everyone, while the private key is  only known to the user himself."}]}],"pr":"ca7e7f60672378c73673341c7aef4a82f60ccdba99be99100ef08e01f565ebc8"}
