The public key is one of a pair of keys generated by asymmetric encryption algorithms, which appear in pairs with private keys. Public keys have uniqueness and can be used to verify transactions and sign digital certificates. In the blockchain network, public keys are mainly used for encrypting and decrypting transaction information, verifying transaction signatures, and participating in consensus mechanisms such as encrypting and decrypting transaction information, verifying transaction signatures, and participating in consensus mechanisms. In short, the public key of blockchain is a technical means used to ensure network security and data credibility."}]}],"pr":"2a12a4ce44030f30133cdbbf2b444138c78d584fbe31ade8c7001444f285235c"}
