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 paradigm shift in the PKI; however, 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 achieves 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 models...
