Encryption protocols are essential for securing transactions and protecting user data in cryptocurrencies. They use mathematical algorithms to encode information, making it readable only to those who have the appropriate decryption key. This ensures that sensitive data, like private keys and transaction details, remain safe from unauthorized access.A common example of an encryption protocol is Public Key Infrastructure (PKI). In PKI, users generate a pair of keys: a public key, which can be shared with anyone, and a private key, which must be kept secret. When a user wants to send a transaction, they use the recipient’s public key to encrypt the data. Once encrypted, only the recipient can decrypt it using their private key.Encryption protocols also help in maintaining the integrity of the blockchain by preventing tampering. They ensure that once a transaction is recorded, it cannot be altered without detection. This combination of security and data integrity is fundamental for trust in cryptocurrency systems.
