By incorporating advanced cryptographic algorithms, blockchain networks can provide robust protection against cyber threats and unauthorized access.
One critical encryption technique in blockchain networks is public key cryptography. This method relies on a pair of unique keys – a public key and a private key – for each user or participant. The public key is openly shared and used for encryption, while the private key remains confidential and is used for decryption.
By leveraging public key cryptography, blockchain networks can validate configuration modifications, authenticate devices, and secure communication channels. When a user initiates a transaction, it is signed with their private key, serving as a digital signature or proof of authenticity. The transaction can then be verified by other network participants using the user’s public key.
