PKI has major vulnerability because of its centralized management system. Blockchain, however, is fundamentally decentralized and allow communication between several parties without any third-party involvement. The approach of going decentralized can be a paradigm shift in the PKI; therefore, it needs a systematic approach to deploy it.
Blockchain is about achieving a decentralized network of multiple participants without third-party involvement. A decentralized public key infrastructure (DPKI) is an innovative concept that creates authentication systems over public systems without depending on a single third party that can compromise the integrity and security of the system.
