Hyperledger Fabric

Overview

Hyperledger Fabric is a Graduated project under the Hyperledger umbrella, designed for distributed ledger solutions. Its modular architecture provides high levels of confidentiality, resiliency, flexibility, and scalability. Hyperledger Fabric allows for pluggable implementations of various components, accommodating the complexities of different economic ecosystems.

This platform offers a uniquely elastic and extensible architecture, setting it apart from other blockchain solutions. Building on a fully-vetted, open-source framework, Hyperledger Fabric is an ideal starting point for enterprise blockchain initiatives.
