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.

Join us for the other Fabric-X meetups

• October 21: Fabric-X – Programming Model and Application Development Deep Dive
• November 19: Fabric-X-Orderer Overview: A Scalable BFT Ordering Service for Fabric-X

Speaker

• Senthilnathan Natarajan, Senior Research Scientist at IBM Research

• LF-Decentralized-Trust-labs/hypernate
• LF-Decentralized-Trust-labs/hypernate-samples

Planned agenda

• Greetings & why we built Hypernate
• Feature tour: entities, keys, mappers, middleware
• Live coding: refactor a basic Fabric contract with Hypernate
• Run the samples & pro tips
• Roadmap & contributor Q&A

What you’ll learn

• How to model entities and do clean CRUD without fuss
• Smart key design (primary/composite, numeric pitfalls, value mappers)
• Drop-in middleware (logging, tracing, write-back caching)
• Using HypernateContract, HypernateContext, and Registry
• Running the samples locally — and how to jump in with issues/PRs

Who should attend
Fabric devs, architects, educators, and everyone interested in smart contracts :)


A learning group for zero knowledge and SNARK application development.

During the year we will systematically explore different aspects of zero knowledge and SNARK programming in application development.

Coordination of the learning group is in the discord channel of Linux Foundation Decentralized Trust: https://discord.com/channels/905194001349627914/1329201532628898036

Github repo for the lab:

In this session, we will be wrapping up the whole year and investigate ZK login.

As financial institutions, tokenization platforms, and public blockchains converge, the ability to move assets and data securely across networks, while maintaining compliance, is becoming mission critical. This webinar with Chainlink Labs, an LFDT member, will explore how the Chainlink Digital Transfer Agent (DTA) technical standard and the Chainlink Runtime Environment (CRE) are redefining decentralized interoperability and enabling on-chain fund operations across heterogeneous systems.

The webinar will take place on Wednesday, December 17 at 10AM PT/1 PM ET/19:00 CET/11:30 PM IST
