Imagine a digital form of identity and access control that can replace passwords, forms of physical identification like passports and driver’s licenses and how this can bring about a lot of changes. This has now been made possible as blockchain startup Onename has launched its new product Passcard.

“Currently, passwords help you access your online life just like your wallet and keys help you access your physical life. At a high level, passwords, identity cards, and keys are all forms of access control. Want to enter a bar? Show an identity card that says that you’re over 21. Want to access your Twitter account? Login with the username/password that you used to signup. Want to enter your home? Use the key that unlocks the door.”
The Blockchain Name System, the Underlying Technology
Onename, founded in March 2014, is using revolutionary new blockchain technology called the Blockchain Name System, or BNS to build Passcards. The BNS is very similar to the Domain Name System (DNS); however, it gives stronger guarantees on ownership and security. Also, there are no trusted parties or “root servers”, and it’s completely decentralized. The blogger at Onename informs that there are multiple layers in the BNS:
“At the bottom layer is raw identity data corresponding to user passcards is stored in a decentralized (usually blockchain-based) key-value store like Namecoin or Blockstore. In the middle layer, resolvers read, interpret, and verify data from the datastore and make it readily accessible to services. In the top layer, passcard galleries grab data from resolvers and render it into a visual format.”
The company promises to bring more information about the BNS and requests the developers to check out the documentation and code and help it build out this next-generation infrastructure layer for the Internet. 
Multiple Uses of Passcards
Not just Passcards will expand upon the company’s earlier blockchain identity product but help users with multiple features. Onename says there are plenty of uses of Passcards; for instance, the users will be able to use Passcards to enter their apartment or office and even when asked to present identification in an in-person context. The company’s move aims to enable blockchain profiles to be used to log into websites and apps as this will give the product its first real use case and actual utility. The blog post at the website reads:
“Your passcard is your identity that you truly own. It is open source, secured by the blockchain, and open for anyone to participate in. There are no walled gardens, and you can sign up using any “registrar”, including Onename, which is also actively participating in the development of this technology.”
