Bitcoin transactions rely on the use of cryptographic keys to provide security and authenticity. These keys consist of a public key and a private key, which are mathematically linked.
1. Public Key:
The public key serves as an address that can be shared with others to receive Bitcoin. It is derived from the private key through complex mathematical operations. While the public key can be freely shared, it cannot be used to determine the corresponding private key.
2. Private Key:
The private key is kept secret and serves as proof of ownership over the bitcoins associated with a specific address. It is used to digitally sign transactions, proving that the transaction is authorized by the rightful owner of the bitcoins.
The combination of the sender’s private key and the recipient’s public key ensures the security and integrity of Bitcoin transactions. The use of asymmetric cryptography allows for secure transactions without revealing sensitive information.
