Cryptography is key to secure blockchain transactions. It uses public and private keys to encrypt and decrypt data. For example, when sending $BTC , the sender uses the recipient's public key to encrypt the transaction. The recipient then uses their private key to decrypt it. Hashing is another crucial concept, creating a fixed-size string of characters from any piece of data. Elliptic curves, like secp256k1 used in $ETH , enable efficient key generation and verification. Understanding these basics is essential for grasping blockchain security. The security of $BTC transactions is at a high level due to these cryptographic techniques. Blockchain protocols rely on them. blockchainsecurity #cryptographybasics #bitcoinsecurity
