Jane wakes up to the sound of her alarm clock – it’s 6:13 AM. “Oh great, what am I in for today,” she thinks. Jane’s alarm clock is normally set for 6:30 AM, but her identity agent detected a traffic accident that is projected to add 17 minutes to her commute. Jane’s identity agent, acting on her behalf, changed her alarm while she was sleeping. All three – Jane’s identity, the identity of her alarm clock, and the identity of her agent – are connected via a self-sovereign, decentralized, blockchain-anchored identity system.
Jane gets ready and grabs a yogurt from the fridge as she heads out the door. The yogurt was delivered yesterday, after her fridge detected she was out. Her fridge’s identity has been granted limited access to initiate purchases for her. In this case, Jane has opted to be notified for confirmation of any purchases her fridge initiates; yesterday Jane swiped “Confirm” when the identity management app on her phone asked if the fridge could execute a purchase of some groceries. The fridge executed a payment over the blockchain using Jane’s identity-linked blockchain wallet and the wallet linked to the grocery store’s identity. That’s right, the grocery store has a blockchain-anchored identity as well. Starting to get the picture?
Jane needs to get to a downtown office building where she is scheduled to meet a contact on the 12th floor. Jane doesn’t have a car, so she asks her identity agent to fetch her one by leveraging the many identity crawlers dedicated to indexing sharing economy identity data. These crawlers are always hard at work, real-time indexing the (user allowed) blockchain identity data changes of every person, place, device, and intangible entity on Earth. In this case, there are hundreds of drivers in Jane’s general vicinity who have granted popular ride sharing identity agents access to read and update their identity’s ride sharing fields. Jane uses her preferred crawler’s app to send signed, encrypted requests directly to providers of sharing economy services. The crawler identifies a driver whose identity shows a ride sharing status of “Available,” with a geolocation value that indicates he is close to Jane. Jane taps “Request a Ride” on the app and it immediately sends a message to the communication endpoint listed on the driver’s blockchain identity. The driver’s blockchain sharing economy app alerts him that a new ride request was received and asks whether he wants to accept. The driver accepts and is sent Jane’s current geolocation.
Upon arriving at her destination, Jane authorizes a payment of her driver’s identity-linked blockchain wallet. She enters the office building and heads directly for the elevators, bypassing a lengthy check-in procedure in the ground floor lobby. Jane taps her phone against an NFC pad, which instantly identifies her via a challenge/response verification of her identity assertion. The elevator system’s blockchain-anchored identity has been given access to the appointment schedules of the various software systems used by the companies that reside in the building. It uses Jane’s identity datastore to locate the appointment entry, which was created by her contact. Within this entry is a signed directive to allow Jane’s identity to access the elevator and take it to the 12th floor. Jane enters the elevator and the button for the 12th floor is already lit up. Just for fun, Jane tries hitting other buttons. But alas, she was not granted access to other floors, so the buttons don’t light up and she isn’t able to access them.
Jane walks up to the front desk and alerts the attendant that she has arrived for her meeting. The attendant directs her to verify her identity once more, via the guest terminal. Jane is greeted by her contact and smiles at the thought of how efficient and interoperable the world has become, thanks to the universal blockchain-based identity system.
