Cryptographic Signature Schemes

Cryptographic signature schemes are mathematical protocols used to verify the authenticity and integrity of messages or transactions in a blockchain network. By using public-key cryptography, a sender proves ownership of an address without revealing their private key.

In options trading, these signatures are essential for signing orders that are sent to off-chain order books before being settled on-chain. If a signature is invalid, the network will reject the transaction, preventing unauthorized trades.

These schemes ensure that only the rightful owner of an asset can move it or authorize a derivative contract. They provide the foundational trust required for decentralized financial interactions.
