Sequential Signatures

Definition ∞ Sequential signatures are cryptographic signatures where each successive signer adds their approval to a transaction in a specific, predetermined order. Unlike multi-signature schemes where approvals can be collected in any order, sequential signatures enforce a strict sequence of authorization. This method provides an auditable trail of approval steps, ensuring that each party has reviewed and validated the transaction at their designated stage. They are often employed in complex workflows requiring phased approvals or conditional releases of digital assets.
Context ∞ Sequential signatures are relevant in blockchain governance and enterprise applications requiring structured approval processes, often appearing in news related to supply chain or legal tech. Their utility in enforcing specific operational procedures is a key advantage for regulated digital asset activities. Current discussions address the integration of these signature types with smart contract logic for enhanced automation and compliance.
