Explain the necessity and tools of Hyperledger Fabric?

Hyperledger Fabric is a blockchain framework implementation and one of the Hyperledger projects hosted by The Linux Foundation. It is designed to be a foundation for developing applications or solutions with a modular architecture.

The necessity of Hyperledger Fabric:

1. Privacy and Confidentiality: Hyperledger Fabric allows private transactions and confidential contracts, which means that the details of the transactions are only available to the stakeholders involved.

2. Scalability and Performance: Hyperledger Fabric uses a modular architecture allowing network designers to plug in their preferred implementations, which can improve scalability and performance.

3. Modularity: Hyperledger Fabric has a modular architecture and provides a lot of flexibility in terms of what you want to use or not use and how you want to plug these modules together.

4. Chaincode Functionality: Hyperledger Fabric allows for business logic to be programmed in chaincode (smart contracts), which leads to the automation of business processes.
