Hyperledger fabric is the framework for building________ applications.

Hyperledger Fabric is a permissioned blockchain framework designed specifically for enterprise solutions and applications. It provides a robust platform for developing decentralized applications that require strong confidentiality and trust among participants.

By utilizing smart contracts and a modular architecture, Hyperledger Fabric allows organizations to create applications that facilitate secure transactions and data sharing without relying on a central authority. This unique capability of managing digital assets in a distributed ledger format makes Hyperledger Fabric ideally suited for various industries looking to leverage blockchain technology for improved operational efficiency, increased transparency, and heightened security.

The other options, while they represent significant areas of technology, do not align with the core functionality and purpose of Hyperledger Fabric. Applications built on Hyperledger Fabric specifically relate to the functionalities enabled by blockchain technology, making it clear why the choice emphasizing blockchain is the correct answer.
