It has a flexible approach to data privacy: data isolation where it uses
“channels” or share private data on a need-to-know basis using private
data “collections”
It offers multi-language smart contract support with Go, J ava, and
J avaScript
It has support for EVM and Solidity
It is designed for continuous operations, including rolling upgrades and
asymmetric version support
It offers governance and versioning of smart contracts
It has a flexible endorsement model for achieving consensus across
required organizations
It offers queryable data (key-based queries and J SON queries)
The security, usability, robustness, performance, and feature set—
all qualities
that are of critical importance to enterprise users have been continuously
improved by a strong Hyperledger Fabric community which is comprised of
many world-class technology providers and individual contributors, all
collaborating to evolve blockchain technologies at a record pace. It supports
the foundation for innovation, quality, and quick delivery that only open source
can provide due to the diverse ecosystem. Blockchain is a foundational
technology, one that is poised to transform and optimize the way the world
transacts; it only makes sense for the technology to be open and for a variety of
contributors to be involved. There are several key contributors to Hyperledger
Fabric, and you can find them listed at: hyperledger.org/ resources/ vendor-
directory
What drives continuous, rapid innovation of Hyperledger Fabric is the
combination of industry, academic, and individual contributions.
There exist hundreds of networks in production today with blockchain
technology has moved forward. Many of the production blockchain solutions
in production today are built with Hyperledger Fabric. A list of tools and

How data privacy is maintained? End-to-End transaction flow
In Hyperledger Fabric, the four aspects of maintaining data privacy are:
