[Fabric-X is a digital asset-specific implementation of Hyperledger Fabric](https://www.lfdecentralizedtrust.org/blog/new-major-contribution-to-hyperledger-fabric-purpose-built-implementation-for-next-gen-digital-assets). 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](https://github.com/hyperledger/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.
