Public Key Infrastructure (PKI) is a system of hardware, software, policies, and procedures required to manage digital certificates and public-key encryption. PKI verifies the identity of users and devices, enabling secure electronic transactions and communications. It establishes trust in digital interactions by linking public keys to verifiable identities.
Context
While many core blockchain protocols operate without traditional PKI, the concept of public key management is fundamental to digital asset ownership and transaction signing. News might reference PKI when discussing the security models of centralized crypto exchanges, enterprise blockchain solutions, or regulatory efforts to establish identity verification standards for digital asset services. The principles of key management remain central to digital security.
