• Encryption is the process of scrambling data in such a way that it is either unreadable by humans or takes a long time for a computer to decrypt. Public/Private (RSA Security) key encryption is used in block chains.
• To keep the data in the block safe, blockchain uses encryption, which can only be decrypted by users who have a valid private key.
• Encryption is a technique for encrypting data so that only authorised parties may decipher it. It is the process of transforming plaintext to ciphertext in technical terms. To put it another way, encryption modifies readable data to make it appear random. An encryption key is a collection of mathematical values that both the sender and the recipient of an encrypted message are aware of.
• A blockchain acts as a database, storing information in electronic form. Blockchains are well known for their critical function in keeping a secure and decentralised record of transactions in cryptocurrency systems like Bitcoin.
