The public key is used to generate digital signatures, while the private key is used to verify digital signatures. In a blockchain network, the transaction initiator signs the transaction information with their own private key, and then other validators use the public key to verify the authenticity of the signature. This process ensures the security and immutability of transactions in the blockchain network."}]}],"pr":"67d50f8f774fe9f7bb985a48f0477de769dc46d4cd859a7b45b80e966a3e96af"}
