See all- Network event1 attendee from 166 groups hostingFabric-X – Programming Model and Application Development Deep DiveLink visible for attendees
Fabric-X is a digital asset-specific implementation of Hyperledger Fabric. Join us for a series on meetups that go into detail about what Fabric-X is and how you can use it.
Fabric-X introduces a new programming model that redefines how business processes are developed on the blockchain. In this session, we’ll take a deep dive into the endorsement phase of Fabric-X, highlighting how it differs from the traditional Hyperledger Fabric model and what these changes mean for developers.
Through hands-on examples, we’ll demonstrate how the new model streamlines development and unlocks exciting possibilities for designing decentralized applications. We’ll also explore how to build applications tailored for tokenization use cases, enabling seamless on-chain asset representation and transfer.
To close the session, we’ll walk through practical deployment strategies using Ansible and Kubernetes, equipping you with the tools and confidence to bring your Fabric-X solutions into production.

- Network event257 attendees from 166 groups hostingTechnical Workshop about Blockchain Interoperability With Hyperledger CactiLink visible for attendees
For anyone interested in learning more about interoperability across different blockchain networks, you're welcome to join this in depth technical workshop about Hyperledger Cacti, a modular, enterprise-ready blockchain interoperability framework.
Target Audience
This workshop is designed for developers, blockchain enthusiasts, and enterprise stakeholders interested in enhancing their understanding of DLT interoperation and standardized asset transfer protocols. Prior knowledge of blockchain concepts and familiarity with Hyperledger Cacti will be beneficial but not mandatory.
Speakers

Venkatraman Ramakrishna, Senior Researcher - Network event1 attendee from 166 groups hostingFabric-X-Orderer Overview: A Scalable BFT Ordering Service for Fabric-XLink visible for attendees
Fabric-X is a digital asset-specific implementation of Hyperledger Fabric. Join us for a series on meetups that go into detail about what Fabric-X is and how you can use it.
Fabric-X-Orderer is the new ordering service designed for Fabric-X, built on a scalable Byzantine Fault Tolerant (BFT) consensus protocol named Arma. Arma introduces key architectural innovations to support high transaction throughput, including the separation of consensus from transaction dissemination, and the use of sharding and pipelining to enhance parallelism in transaction processing. These techniques enable Arma to achieve over 100,000 transactions per second (TPS) for small transactions, meeting the performance targets of Fabric-X.
In this meetup, we will provide an overview of the Fabric-X-Orderer architecture, delve into the underlying protocols, and share performance evaluation results that highlight its scalability and efficiency.

- Network event1 attendee from 166 groups hostingFabric-X-Committer: A Microservices-Based Architecture for Ultra-High ThroughputLink visible for attendees
Fabric-X is a digital asset-specific implementation of Hyperledger Fabric. Join us for a series on meetups that go into detail about what Fabric-X is and how you can use it.
Fabric-X-Committer introduces a high-performance and resilient architecture that addresses the scalability limitations of the traditional monolithic peer in Fabric. By decomposing the commit process into independently scalable microservices—including a Coordinator, Signature Verifiers, and Validator-Committers and leveraging a sharded distributed database, the system achieves significant parallelism, enabling substantial scalability and performance gains.
A key innovation is the use of a transaction dependency graph, which allows safe, parallel validation of transactions across multiple blocks. Combined with a pipelined execution flow, this design eliminates sequential bottlenecks and unlocks ultra-high throughput. Performance evaluations show that Fabric-X-Committer can process over 200,000 transactions per second, marking a major leap in scalability for enterprise-grade blockchain systems.
In this meetup, we will provide an overview of the Fabric-X-Committer architecture and share performance evaluation results that highlight its scalability and efficiency.
