Query: Towards a Blockchain based digital identity verification, record
  attestation and record sharing system   The Covid-19 pandemic has made individuals and organizations to rethink the
way of handling identity verification and credentials sharing particularly in
quarantined situations. In this study, we investigate the inefficiencies of
traditional identity systems, and discuss how a proper implementation of
Blockchain technology would result in safer, more secure, privacy respecting
and remote friendly identity systems. As a result, we propose a Blockchain
based framework for digital identity verification, record attestation and
record sharing, and we explain the framework in details with certain use cases.
Our proposed framework promotes individuals to fully control their identity
data and govern the level of the identity data sharing.
