Cryptographic Key Pairs

Cryptographic key pairs consist of a public key and a corresponding private key, which form the mathematical foundation of blockchain transactions. The public key acts as an address, similar to a bank account number, which can be shared openly to receive funds.

The private key acts as a digital signature, allowing the owner to prove they control the address and authorize the movement of assets. This asymmetric encryption ensures that transactions are verifiable by anyone on the network while remaining immutable and secure.

The relationship between the two is unidirectional, meaning the private key can derive the public key, but the public key cannot be used to calculate the private key. This mathematical structure is what enables trustless value transfer in decentralized systems.
