Fabric-X-Committer: A Microservices-Based Architecture for Ultra-High Throughput

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.
