Deployment Key

Definition ∞ A deployment key is a cryptographic credential granting authorization to publish or modify software, such as smart contracts or decentralized applications, onto a blockchain network. It functions as a secure access control for code releases and updates. Possession of this key permits alterations to the operational logic of a protocol.
Context ∞ The security of a deployment key is absolutely vital for maintaining protocol integrity and user trust. Any compromise of such a key could permit unauthorized code changes, leading to severe system vulnerabilities, the siphoning of funds, or a complete shutdown of services, issues often reported in security incident news.
