Proof of Moin Hackathon

Thank you, everyone, for participating!

What is Proof of Moin?

Proof of Moin is the very first community focused blockchain hackathon in Hamburg taking place on 6-8 September in 2019.

We started two years ago forming the blockchain community in Hamburg by organizing the Blockchain Mania meetup series. Once in a month, the growing blockchain community gathers to discuss distributed ledger related topics and new developments in that area.

The aim of this hackathon is to connect blockchain experts, developers, and designers in order to create and invent distributed ledger products that allow individuals or organizations to collaborate in a decentralized world.

Proof of Moin brings together challenges that matter and technology that works. Read on to see what we are up to!


Personal Data

Today personal data is characterised by keywords like GDPR, data silos, loss of control and you being the product.

How can you change that?

If you choose this challenge you will endeavour to create a prototype that will help individuals collaborate in topics like self-sovereign identity, privacy respecting data markets and multi party computation.

Government & Society

Static governmental structures, bureaucratic obstacle and tedious interactions with authorities is our reality nowadays.

How can you change that?

If you tackle this problem you will make a contribution to a modern society that is enabled to share goods and services co-determinatively and to interact with authorities in an accessible and secure way.

Supply Chain Management

Almost every object of our daily life went through some supply chain. However, most of the supply chains do not provide transparency and traceability.

How can you change that?

If you embrace this challenge you will build an initial solution that can help keeping track of the origin of a product in order to reduce counterfeits and help designing efficient logistics, warehouses and transportation.

Use one of our tech stacks, oracle solutions and whatever other tools you need to solve one of these crucial problems!
