2. Modular Architecture: One of the primary goals is to create a modular architecture, making it easy for organizations to mix and match components to overcome specific business needs. This modularity translates to flexibility, enabling implementers to tailor blockchain networks.

3. Collaborative Development: Hyperledger encourages collaborative development. This ecosystem approach ensures rapid innovation and shared solutions for common problems.

Key Components

Hyperledger Fabric

Hyperledger Fabric is an enterprise-grade, distributed ledger platform that uses smart contracts to support data privacy and confidentiality requirements. Fabric is designed for use cases across a variety of industries.

Key Features

• Modularity: Hyperledger Fabric is fully modular. Components such as consensus and membership services are plug-and-play.
• Permissioned: Access to the ledger can be restricted to approved members, enhancing security.
• Multi-Language Smart Contracts: It supports Chaincode (smart contracts) written in Go, JavaScript, and Java.

Hyperledger Sawtooth

Hyperledger Sawtooth provides a highly modular platform for building, deploying, and running distributed ledgers. It aims to keep ledgers distributed and maintain Smart Contract and transaction logic free from the core system, making it suitable for large enterprises.

Key Features

• Parallel Transaction Execution: Enhances throughput and scalability.
• Dynamic Consensus: Consensus can be adjusted without stopping the network or rewriting code.
• Flexible Permissioning: Allows for public and permissioned blockchain applications.

Hyperledger Iroha

Hyperledger Iroha is a blockchain framework tailored for simple and straightforward use case integrations. It is particularly focused on mobile development.

Key Features

• Easy Integration: Iroha is designed to be easy to integrate into various projects, featuring simple APIs and a permissive Apache 2.0 licensing.
• Rich Set of Functions: Includes a wide set of pre-built commands and queries for managing assets, information, and permissions.

Hyperledger Indy

Hyperledger Indy is a distributed ledger system designed for decentralized identity management. It provides tools and libraries essential for decentralized identity ecosystems.

Key Features

• Self-Sovereign Identity: Focuses on enabling independent digital identities that are operated and controlled by the entities who own them.
• Verifiable Credentials: Supports issuing, storing, and verifying credentials in a trustworthy manner.

Hyperledger Besu

Hyperledger Besu is an Ethereum client designed for enterprise use. It can be used for both public and private networks.

Key Features

• Enterprise Integration: It includes features that support enterprise use cases like monitoring, permissioning, and enhanced privacy.
• Standards-Based: Built to comply with the existing Ethereum specifications, ensuring compatibility.

Governance and Community

The Linux Foundation

Hyperledger is governed by The Linux Foundation, which administers a variety of collaborative projects. The foundation plays a pivotal role in the governance of the project by maintaining infrastructure, legal support, and empowering collaboration among project contributors.

Technical Steering Committee (TSC)

The TSC governs and maintains the strategic direction and administrative matters of Hyperledger projects. It sets technical guidelines and ensures the coherence and coordination between various sub-projects.

Collaboration with Industry

Hyperledger actively collaborates with industry leaders. Its network ranges across finance, banking, IoT, supply chain, and technology, ensuring that the blockchain solutions meet real-world, industrial needs.
