Asymmetric cryptography, also known as public-key cryptography, involves a pair of keys for secure communication. One key is public and can be shared with anyone, while the other is private and kept secret by the owner.In transactions, the public key is used to encrypt data, ensuring that only the holder of the corresponding private key can decrypt it. This method enhances security, as even if the public key is known, the private key remains confidential.This cryptographic approach is vital for creating digital signatures. When a user signs a transaction with their private key, others can verify it using the public key. This process confirms the authenticity and integrity of the transaction, ensuring that it has not been altered.Asymmetric cryptography is fundamental to user identity security, preventing unauthorized access and enabling secure peer-to-peer transactions. It lays the groundwork for trust and transparency in decentralized networks, as it mitigates the risk of fraud and ensures that users can transact confidently.
