Thanks mate . There are few blockchain based identity validation platform, each with its own features. Some validate your identity by registering your ID card to your wallet.For example, on SelfKey Network, an identity owner can have a validator such as a notary, to verify the documents in their wallet. They can then share their certified documents with service providers during ID verification processes (e.g. when applying for a bank loan), again via the SelfKey Network.
Some of these platforms are so authentic that some major websites integrate with them as a login option, not requiring passwords of users anymore. For instance, wikiHow, a popular "how-to" guides community with over a 100million users integrated with Civic to allow users login with their verified identity.
I hope you find this little piece of information useful mate.Thanks for airing your views and for the kind comments :)
