Hyperledger Fabric
The Hyperledger Fabric v3.0.0-beta has been released. The major feature in v3.0.0 is the Byzantine Fault Tolerant (BFT) ordering service based on the SmartBFT consensus library. Hyperledger Fabric has utilized a Raft crash fault tolerant (CFT) ordering service since version v1.4.1. While the Raft CFT ordering service will continue to be available, a Byzantine Fault Tolerant (BFT) ordering service can withstand not only crash failures, but also a subset of nodes behaving maliciously. Consider using the BFT orderer if true decentralization is required, where up to and not including a third of the parties running the orderers may not be trusted due to malicious intent or being compromised. For more about what's in the beta release, check out the note on the Fabric list.
Code & Projects
Hyperledger Bevel
The maintainers of Hyperledger Bevel are starting work on a Kubernetes Operator for Hyperledger Besu and they're looking for your help. They currently have a Helm based operator only and are looking to evolve that into a complete operator for Hyperledger Besu as a way to make deploying Besu networks easier and quicker. If you're interested, check out the recording of their recent meetup about Deploying Production Networks with Hyperledger Bevel Helm Charts and check out the new repo for the bevel-operator-besu development.
Hyperledger Iroha
The Hyperledger Iroha project is putting out a call for contributors. Iroha is a straightforward distributed ledger technology (DLT), inspired by Japanese Kaizen principle — eliminate excessiveness (muri) and it is being used in a production central bank digital payment system. If you're interested in the opportunity, check out the Iroha Tutorial to get familiar with what it does and then pick up a good first issue to start contributing.

For anyone going to Open Source Summit North America in Seattle, join us for a 3.5-hour symposium hosted by the Hyperledger Foundation on Monday, April 15, 2024 from 1:30 to 5 PM. The event will focus on the pivotal themes of decentralization, identity and multi-party systems and featuring leading experts and practitioners in blockchain and distributed ledger technology. This is a unique opportunity to delve into how Hyperledger technologies are driving innovation and solving real-world problems across various sectors.This event is part of Open Source Summit North America being held at the Seattle Convention Center from April 16-18. If you're planning to go to OSSNA, add this Hyperledger event to your registration. If you haven't signed up for OSSNA yet, get 20% off registration with this discount code: OSSNA24MINI20. There are also reduced ticket prices available for Academics, Government employees and Hobbyists.The Web3j team will lead Ethereum Development with Web3j and Java: A Hands-on Workshop on Thursday, March 28th at 8amPT/11amET/4pm GMT. Hyperledger Web3j is a interested in learning about the newest Hyperledger project, join us for an in depth technical deep dive about Web3j in English on Thursday, March 28. Web3j is a lightweight, 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.

The Hyperledger Foundation will host the workshop, Zero Knowledge Proofs and ZK Programming in Blockchain Application Development on Wednesday, April 24th at 8amPT / 11am ET / 4pm GMT. 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 rather 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 or Fabric.
