Worum es bei uns geht

The Hyperledger Foundation is an open source collaborative effort hosted by the Linux Foundation and created to advance cross-industry blockchain technologies. Participation is open to all.

Hyperledger Meetup groups have an informal relationship with Hyperledger, and make up a key part of the Hyperledger ecosystem. Participation in a Hyperledger Meetup group is open to anyone--employees of a Hyperledger member company, Hyperledger contributors and developers, and people just passionate about blockchain technology.

Workshop: Using Hyperledger FireFly to Launch an NFT Collection on Public Chains

Network event

Link für Teilnehmer sichtbar

In this workshop, Nicko Guyer, Alex Shorsher and David Echelberger, Full Stack Engineers at Kaleido and Hyperledger FireFly maintainers and contributors, will show you how to use Hyperledger FireFly to launch an NFT collection on public chains.

We’ll provide an overview of Hyperledger FireFly features including:

  • Web3 Gateway Mode - for connecting to popular public chains like Ethereum, Polygon, Avalanche, Optimism, Arbitrum, etc.
  • Public Blockchain Tools - with support for managing and signing transactions
  • Enterprise-friendly functionality - to ensure new apps meet both user and compliance requirements.
  • Integration capabilities - for connecting your NFT app to existing enterprise systems.

From there, we’ll take you through the steps to create and launch an NFT collection on Polygon using Hyperledger FireFly. With live coding and easy-to-follow steps, you’ll have everything you need to launch your own NFT collection.

This session is targeted to developers of intermediate skill level and above, with some prior amount of blockchain knowledge. New developers, or those without any prior blockchain knowledge may still find it informative, as Hyperledger FireFly is very approachable. At the same time, it is also flexible and customizable to meet the needs of experienced blockchain developers.

Registration for the event is free. If you're interested in attending, we ask that you sign up now since space is limited.

How to Apply to Hyperledger's Annual Paid Mentorship Program

Network event

Link für Teilnehmer sichtbar

Every year Hyperledger runs a paid Mentorship Program to create a structured hands-on learning opportunity for new contributors. Each mentee will apply and be matched with a mentor or mentors who are active contributors in the Hyperledger community. Each mentee will work remotely from their location of choice.

This meetup will provide more details about the program, share details about this year's projects and explain how to apply. We'll also hear from previous Mentees about their experience and also hear from Mentors to learn more about what they're looking for in people who apply to the program.

Blockchain and Quantum Resistance

Network event

Link für Teilnehmer sichtbar

In this meetup we will investigate the problems and challenges that quantum computing can cause with today's blockchain protocols, including but not limited to quantum attacks on cryptographical elements of a blockchain or the role of the post-quantum cryptography. We try to cover everything on a high level basis, without going deep into the math-heavy topics.


  1. Welcome to the Hyperledger Community (5 min)
  2. A non-mathematical introduction to recent directions of post-quantum cryptography (20 min)
    - Short introduction about the theories (math/non-math) behind the possible directions
    - 10 months of the NIST finalist, what happened with them?
    - Diffie-Hellman?
    - The real word (SSL? HTTPS? DNS? eBank? Crypto? Blockchain?)
    - Are we there yet? (Hardware, software, the said truth)
    Andras Szabolcsi
    Blockchain Solution Architect
  3. A high level technology-management framework for analysing quantum threats of a Blockchain protocol. (30 min)
    Daniel Szego
    DLT Architect

4. Community Discussion
