## Cryptographic Signatures

Cryptographic Signatures are mathematical schemes that demonstrate the authenticity of a digital message or document. By using a private key to sign a transaction, a user confirms their identity and intent to execute a trade on a derivative protocol.

The signature can then be verified by anyone using the corresponding public key, ensuring that the transaction was authorized by the owner of the assets. This process is the core of non-repudiation in blockchain finance, preventing actors from denying their actions.

These signatures are integral to the security of smart contracts, which automatically execute trades based on valid inputs. They are the fundamental building block of trust in a trustless environment.
