Digital Signatures

Digital signatures are mathematical schemes that demonstrate the authenticity of digital messages or documents. They provide three main security properties: authentication, non-repudiation, and integrity.

In trading, digital signatures are used to sign orders, withdrawals, and other critical actions, ensuring that they originate from the account owner and have not been tampered with. The process uses a pair of keys: a private key for signing and a public key for verification.

This ensures that only the holder of the private key can initiate actions on the account. Digital signatures are the foundation of trust in digital finance, enabling secure and verifiable transactions in a trustless environment.

They are essential for protecting assets and ensuring the accountability of market participants.
