Firstly, it is important to understand what a public key is in the context of Bitcoin. A public key is a unique identifier that is generated when a user creates a Bitcoin wallet. It is derived from the user's private key, which is a secret number known only to the user. The public key is used to receive Bitcoin transactions, while the private key is used to sign transactions and prove ownership of the Bitcoin.
The public key is essentially a long string of characters, typically starting with a "1" or "3" followed by a series of numbers and letters. It is used to identify the wallet and ensure that the sender of a transaction is authorized to send Bitcoin to that wallet. The public key is also used to generate the Bitcoin address, which is a shorter, more user-friendly version of the public key.
Now, let's address the question of whether two people can have the same public key. The answer is no, it is not possible for two individuals to have the same public key. This is because the public key is generated using a one-way mathematical function that is based on the private key. The private key is a random number, and the public key is derived from it using a deterministic process. This means that for every unique private key, there will be a unique public key.
However, there is a related concept that can sometimes cause confusion. This concept is known as "key malleability." Key malleability refers to the fact that certain cryptographic functions can be used to change the form of a public key without changing its underlying value. This means that while the public key itself may appear different, it still represents the same wallet.
For example, if someone has a public key that starts with "1", they could use a cryptographic function to change it to start with "3" without altering the wallet's identity. This is not a concern, as the public key is still used to identify the wallet and receive transactions.
In conclusion, Bitcoin can 2 people have the same public key? The answer is no, it is not possible. Each public key is unique and is derived from a unique private key. While key malleability can cause the public key to appear different, it does not affect the wallet's identity or the ability to receive Bitcoin transactions. Understanding the relationship between private and public keys is crucial for ensuring the security and integrity of Bitcoin transactions.
