Single Signature

Definition ∞ A single signature refers to a transaction that is authorized by only one private key. This is the most basic form of transaction authorization in blockchain systems, contrasting with multi-signature arrangements that require multiple approvals. Single signature transactions are common for everyday wallet operations.
Context ∞ The discussion around single signatures often arises in contrast to more advanced security measures like multi-signature wallets. While simpler and more convenient for individual users, the inherent reliance on a single point of control makes them more susceptible to compromise if the private key is lost or stolen. Future developments may see more sophisticated user-friendly interfaces that abstract away the complexities of signature management while retaining security.
