How can blockchain help?

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.

Decentralized infrastructure

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. As we already know, blockchain is built with a trustless approach that allows both trusted and untrusted parties to communicate with each other. However, trust is usually established among geographically and politically disparate participants with several consensus...
