The process is an algorithm based on elliptic curve cryptography (ECC), where secp256k1 is a specific elliptic curve that has been widely applied in Bitcoin and many other cryptocurrencies. Through the public key recovery operation, users can verify, sign, and encrypt transactions to ensure security and privacy in cryptocurrency networks."}]}],"pr":"eb919c75093cfc3e01724fc111b97b33f5f083ee4e0a69a313136e40f6d4749c"}
