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.

Diablo: A Benchmark Suite for Blockchains

Network event

Link visible for attendees

With the recent advent of blockchains, we have witnessed a plethora of blockchain proposals. These proposals range from using work to using time, storage or stake in order to select blocks to be appended to the chain. As a drawback it makes it difficult for the application developer to choose the right blockchain to support their applications. In particular, the scalability and performance one can obtain from a specific blockchain is typically unknown. The claimed results are often obtained in isolation by the developers of the blockchain themselves. The experimental conditions corresponding to these results are generally missing and the lack of details make these results irreproducible.

In this paper, we propose the most extensive evaluation of blockchain to date. First, we show how the experimental settings impact the performance of 6 state-of-the-art blockchains and argue for more detailed experiments. Second, and to cope with this limitation, we propose a unifying framework to evaluate blockchains on the same ground. The framework includes a suite of 5 realistic Decentralized Applications (DApps), helps deploy the blockchain nodes at different scales and evaluate their performance. Finally, we show that selecting a particular virtual machine or weakening guarantees can help handle computationally demanding workloads but that none of the tested blockchains can yet support the load of these realistic DApps.

Speaker bio: Andrei Lebedev is a PhD student at the University of Sydney. The focus of his research is evaluation and improvement of distributed systems. He received his MSc in Informatics from the Technical University of Munich and has been a technical lead for Hyperledger Iroha, a permissioned blockchain protocol.

Introduction to Decentralized Identity

Network event

Link visible for attendees

This session is meant to be a broad overview of Decentralized Identity. The one-hour discussion will help you understand the topic, why it is important and the new capabilities it gives enterprises and individuals. In addition, we will discuss how it works, and where this work is happening (Hyperledger, Decentralized Identity Foundation, W3C, Internet Identity Workshop, etc.).

For additional information about this topic, check out the next session on Tuesday, Feb 28 at 12 Eastern that will go into more technical detail about decentralized identity.

This event is being co-developed with Morgan State University and Indicio.

Webinar with Corsha: Protecting Software Supply Chains with Hyperledger Fabric

Network event

Link visible for attendees

Modern software and systems utilize many separate libraries and components to enable new use cases for businesses and users alike. Recently, attacks like the SolarWinds compromise have demonstrated the vulnerability of these software supply chains. A malicious actor can modify or remove key components of the supply chain for a given software product or service, with devastating results.

In this webinar, Corsha, a Hyperledger member company, will demonstrate how Hyperledger Fabric is used to power Corsha's Zero Trust solution for securing the software supply chain. The role and purpose of Hyperledger Fabric at Corsha will be discussed, as well as the new use cases are enabled by Corsha's chaincode, running in a Hyperledger Fabric deployment.

Corsha will then conduct a supply chain attack on a popular artifact repository, modifying and removing docker images and other artifacts. Finally, the Corsha Team will show how placing a Hyperledger Fabric-based app in the middle of the supply chain can prevent attacks by only allowing legitimate sources to modify and obtain mission-critical software components.

We hope to see you there!

Our Hyperledger In-depth series features live demos, tutorials, and stories from the battlefield! Members share learnings from their projects, and field all the hard questions about the pains and triumphs of working with DLTs. This is a great opportunity for you to get involved, come prepared with questions and voice your opinions.

Join us in building a stronger community!

IT Service Management (ITSM) for Hyperledger Fabric

Network event

Link visible for attendees

In this meetup we will investigate the possibilities and challenges of integrating Hyperledger Fabric with professional IT Service Management methodologies, like with ITIL (Information Technology Infrastructure Library). We stay close to the technology though and focus mostly on the Fabric specialities at different service management practices, like

- Capacity and Performance Management
- Change Control
- Problem Management
- Incident Management
- Servie Desk
- Sevice Configuration Management
- Service Deign
- Deployment manegement
- Infrastructure and platform management
- ...

The meetup can be regarded as a starting point as well to get more community involvement in this highly relevant topic.
