T-Labs Blockchain Identity Hackathon Berlin #TLabsHACK

On the weekend of January 20th The Blockchain Society together with Telekom Innovation Laboratories (T- Labs) hosted an epic hackathon in Berlin called #T-LabsHACK. The 32-hour Identity & Blockchain Hackathon and Learnathon was designed develop and share blockchain solutions with a diverse group of blockchain professionals from all over the world.

This is the follow-up T-Labs Hack Session, with the first one taking place in Seattle during October of 2018. At the end of February The Blockchain Society will also host a third #T-LabsHack in partnership with Telekom Innovation Laboratories at Carrer de Pujades in Barcelona.


With the increasing popularity of blockchain technology there comes a desire to always be ahead of the curve; at The Blockchain Society #T-LabsHackathons, we bring attendees up to speed on some of the hottest tech to hit the blockchain space, which contestants can then use directly in their Hackathon projects to win great prizes!

The Challenge of the #T-LabsHACK in Berling was centered around Identity Marketplaces. A Learnathon was also included, with a workshop that introduced hashstaX. HashstaX combines different distributed ledger technologies (DLTs) into an enterprise-grade operating stack to enable blockchain-agnostic development of business-relevant decentralized applications. To learn more about hashstaX check out this video.

There was a detailed set of rules that all teams had to follow during the coding process in order to be considered for the first place prize:

1. Fresh Code - Everyone started coding at the same time. It was permitted for coders to work on designs, digital mockups, open source frameworks, and anything else available to everyone beforehand, but things had to be kept within a fair limit.

2. Code Review - Winning teams were subject to a code-review at some point following the event
or immediately before winning. This is to ensure that all code used was in fact fresh.

3. Ownership and IP - All coders had to own their IP and whatever they created.

4. Team Size - Teams could be no larger than five people in order to eligible for competition.

5. Submissions - All hackers received an email with instructions on how to submit their work.

6. Demos - All hackers had to demo the functionality of their project and talk through the idea. Everyone received an email with instructions on how to do just that prior to the event.


The Hackathon projects were all judged based on Technical Deployment, Consumer Centric, Usefulness and Innovation. The judging panel shared had a diverse set of experiences within the blockchain space, and each judge offered a unique perspective and insight regarding the projects that were presented.
