What we’re about
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.

Join us for an exciting Meetup as we dive into the latest release of the AIFAQ tool. This intelligent ChatBot is designed to respond to inquiries about your enterprise's online documentation, GitHub issues, and pull requests.
Join this event to learn more about AI FAQ and explore its potential applications and see how you can get involved. To prepare for this meetup, you can get the code, install it and test it out and then ask the developers any questions you have. Installation instructions can be found in the AI FAQ Github repo.
Take advantage of the opportunity to engage with the latest advancements at the intersection of AI and open-source development. See you at the meetup.

Speakers
- Network event321 attendees from 157 groups hostingEthereum Development with Hyperledger Web3j and Java: A Hands-on WorkshopLink visible for attendees
Hyperledger Web3j is a highly modular, reactive, type safe Java and Android library for working with Smart Contracts and integrating with clients (nodes) on the Ethereum network. This allows you to work with the Ethereum blockchain, without the additional overhead of having to write your own integration code for the platform.
During this in depth hands-on workshop session you will learn:
- Architectural Overview: Understanding Web3j's role in the Web3 ecosystem.
- Project Kickoff: Steps to create your first Web3j project focusing on creating ERC-20 and ERC-721 tokens.
- Deployment Guide: Deploying Web3j applications with Hyperledger Besu, from testnets to your own network.
- Smart Contract Java Wrappers and Interacting with them: Learn how to call smart contract functions and test major Ethereum RPC APIs
- Native Testing: Simplifying unit testing using the Besu EVM (Web3j-unit).
- Transaction Types: An exploration of EIP155, 1559, 4844.
- Network event232 attendees from 157 groups hostingHow to Apply to Hyperledger's Annual Paid Mentorship ProgramLink visible for attendees
Every year Hyperledger runs a paid Mentorship Program to create a structured hands-on learning opportunity for new contributors. Each mentee who applies and is accepted into the program will 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.
Note that applications for mentees opens on April 2 and closes on May 10, 2024.

Zero knowledge proofs and SNARK systems are becoming one of the revolutionary technologies of the beginning of this century. In this workshop we will give a high-level introduction to the zero knowledge and SNARK technology stack from a software developer and IT professional perspectives with covering only slightly the deep mathematical basis. During the workshop we will implement an experimental zKRollup system in Circom on Hyperledger Besu.
Agenda:
-
A conceptual introduction to zero knowledge proofs (45 min - presentation)
A gentle introduction to prover, verifier, interactive versus non-interactive models, SNARKs, zkSNARKs, computation models, arithmetic circuits, rank-1 constraints, DLS languages and accumulators. -
Introduction to Circom programming (45 min - labs and Hands-on)
We will cover with lab exercises and hands-ons basic elements of the Circom programming language and the development flow including circuit and rank-1 constraint generation, compilation, power of tau, proving and verifying.
- Break + discussion (15 min) -
zkRollups basics (30 min - presentation)
A general introduction to the conceptual elements of zero knowledge rollups. -
Implementing a simplified zkRollup for token transfer and integrating with Hyperledger Besu or Fabric (30 min - lab and demo)
During the demonstration and lab we will implement a prototype zero knowledge rollup for a simplified token transfer and integrate it with Hyperledger Besu or Fabric. -
Conclusions and discussion (15 min + )
Workshop Leaders:
- Andras Szabolcsi: Blockchain and solution expert, co-founder at BlockBen and Natrix. Highly skilled and experienced System and Solution Architect in the financial software developing industries.
- Daniel Szego: DLT Architect
