What is the use of Bitcoin signature (the process of verifying Bitcoin transaction signatures)?

What is the use of Bitcoin signature? According to official sources, there are many principles for digital signatures on the blockchain. For example, a transaction can be completed through smart contracts: the sender can input the secret key to write it into the public key (as shown in the figure), and then the password will be encrypted and stored in the Bitcoin ledger. Private Bitcoin addresses or files can be generated using open-source software development kits (SDKs) and hardware wallets (Applets), and they can be logged in using mobile numbers, emails, and other electronic mail accounts.

Process of verifying Bitcoin transaction signatures

According to bitcoinist reports, the process of verifying Bitcoin transaction signatures is a complex one. It involves using the uniqueness of the signature to prove that the sender of the transaction has sufficient information and confirmations. This can be seen as a method where users encrypt their private keys into bytes as readable text upon receiving them. Then, they write their signature information into their computers and store it on their local hard drives.
