What is a bitcoin public key and a private key?
Could you elaborate on the concept of a Bitcoin public key and a private key? As a cryptocurrency and finance professional, I understand the importance of these cryptographic elements, but I'm curious to hear your perspective. Specifically, what is the role of each key in the Bitcoin ecosystem? How do they work together to ensure the security of transactions? Additionally, what measures should users take to safeguard their private keys to prevent loss or theft? I'm interested in understanding the fundamentals of these cryptographic keys and how they facilitate the secure transfer of Bitcoin.
