It is generated through asymmetric encryption  algorithms, appearing in pairs with private keys. In a blockchain network, the main function of the public key is to encrypt transaction information to ensure the security of the information during transmission. Meanwhile, public keys are also used to verify identities and create digital signatures to prevent tampering with transaction data. In summary, the public key in blockchain is an essential security tool for maintaining the security and trustworthiness of the blockchain network."}]}],"pr":"d3257672c89947c88a9a4d8ac9c1be998c75dd7e451c1f37aa56856edbf5d1c6"}
