32 hours to prove the decentralized identity use case

Flashbacks  •  
Jan 23, 2019

Over 32 hours, 78 developers in 13 teams turned talk into working code and showcased demos for innovative, blockchain-backed products across a range of services —from e-commerce, health, travel, security, marketing, and more.

This past weekend the T-Labs, Telekom Innovation Laboratories hosted a blockchain identity hackathon at hubraum in Berlin, organized by Blockchain Society, and in partnership with MobiledgeX, Inc.IOTAMoecoMinespiderCode UniversityTrusted IoT AllianceBerchain, and Jolocom.

We could not be prouder that so many of the teams used Jolocom to create their solutions — including two of the three winners. The diversity of application for self-sovereign identity protocols lead us to believe that these are some of the use-cases where you might see decentralized identities take root in 2019 and beyond.

First place:
Integrated e-ID — PiDee

Intent on showing both a practical application for a decentralized identity, and that a blockchain application could run on a small computer, winning team PiDee created a Jolocom identity on Raspberry Pi which is capable of interacting with passport and ID card credentials. Combining Jolocom’s SSO credentials on the Raspberry Pi + IOTA payment, their demo enabled a user to:

  • Register their identity on their smart phone
  • Verify their identity credentials
  • Share those credentials with a ride-sharing app
  • Issue a payment which triggers the launch of an application
  • Use that application to unlock their rental car

We see this as a next step for ride-sharing applications. It benefits the user by allowing them to seamlessly login to any ride-sharing application (with a Jolocom sign on option) while minimizing what data is shared and maintaining control over that data which is housed only in their smart phones. In this scenario, ride sharing companies also benefit from this much faster user on-boarding while still getting the trusted user data they need.

Third place:
Insurance — Helia

Team Helia disrupted health insurance using blockchain and self-sovereign identity. How? In the current insurance system, there are flat rates offered to customers within certain tiered groups. Helia introduces a variable option so that after purchasing insurance, users can track their physical activity. Stored on a decentralized database, they can first share this data with insurance companies who can adjust their future insurance plans, and also with doctors and medical professionals.

In addition to a functioning demo, team Helia fleshed out a business model, customer journey, and value proposition canvas to support their product. As if this wasn’t enough to convince us that there is most certainly a need for their service and a space in the market for its implementation, the team also won third place.

E-commerce — Buy By ID

While not a winner, Team Buy By ID was one of our favorite solutions from #TLabsHACK. Coming from a mixed e-commerce and programming background, the team integrated the Jolocom self-sovereign ID wallet app with Vue Storefront’s checkout system enabling users to check out by simply clicking a “submit my data” button and confirming said transaction in the Jolocom app.

The store owner can then verify each user, issue a transaction ID and wait for the payment to be made before then handing over the order to a shipment provider. This process minimizes the information sent from user to shop-owner, maximizes the efficiency of each transaction, and still gives the store the trusted data it needs to be able to fulfill shipments. After all, “why should a shop owner actually know my home address if he doesn’t want to visit me for tea?”

Ride-sharing — Smart City

While this team didn’t use the Jolocom protocol, team T-Systems developed a smart city ride share application using Sovrin’s self-sovereign identity protocol in combination with golang, kotlin, android, iota, and ethereum. This solution to car-sharing is community-based, where riders download the app to find nearby drivers who then pick them up along similar routes. Riders pay for trips using internal currency, which they earn from engaging in socially and ecologically beneficial activities.

T-Systems’ app not only provides an answer to problems of over-crowding, air pollution, smog, and congestion, but has the added incentive package that encourages users to do social and environmental good.

In addition to the self-sovereign identity products listed above, the hackathon also saw amazing results from the other participants, who are sure to go on and revolutionize the space of blockchain and identity.

Trust Travel

This team is making travel safer for tourists using Blockchain by bringing authorities (government, private, or local ), issuers (identity verifiers), and users (tourists) onto an immutable secure blockchain based network.

5g IoT ID by Moeco

People and machines make their decisions based on petabytes of data generated by IoT devices, but there are ways in which that decision can be wrong (devices compromised, blockchains spoofed, IoT device data transfer limitations). This solution mitigates against these risks by signing data from every device with Digital Signature.

Backstage

Team Backstage helps artists by allowing them to build a ‘backstage’ platform on their websites/marketing platforms that allows them to share exclusive content and tokenize their work on the Ethereum blockchain.

V.I.C. (Very Important Contact Card)

Team CryptoManiacs created a V.I.C. (Very Important Contact Card) to allow famous people to prioritize their communications by offering different sets of business cards for distinct audiences.

mShare

Team mShare helps users create a secure medical identity to manage their various medical accounts on multiple partners’ websites, blockchains and digital solutions — and even make a small, passive income.

CryptoFreeze

Team Unicorn developed a blockchain-backed security solution called “Crypto Freeze.” It enables people to freeze all of their accounts with a single click of a button and then recover their digital identity when the threat has passed.

mVISE

Team mVISE developed a “Pokemon Go” for blockchain that connects trusted digital identities and marketing messages via a gamified app that fosters interactions and networking and lets users earn money.

Akira

Team Akira wanted to get rid of passwords and to be able to handle registration and sign ins with a user’s main identity. To accomplish this, they developed an identity for a chain and other chains that handles facial recognition for sign in and transactions that send digital signatures.

MedID

Disrupting medical record-keeping and identity interactions was the goal of the MedID team. They developed a solution that stores the unique medical identity of a person based on mental and physical conditions that can be shared with medical and public service providers.
