Key Frameworks
Hyperledger Fabric
Hyperledger is an open-source collaborative effort hosted by the Linux Foundation, created to advance cross-industry blockchain technologies. Unlike public blockchains like Ethereum or Bitcoin, Hyperledger focuses on developing enterprise-grade, permissioned blockchain frameworks and tools designed for business applications.
The most widely adopted Hyperledger framework, Fabric provides a modular architecture for enterprise blockchain solutions. Its key features include:
- Permissioned network structure
- Pluggable consensus mechanisms
- Private channels for confidential transactions
- Smart contracts (“chaincode”) support
- Modular architecture for flexibility
Hyperledger Besu
An Ethereum client designed for enterprise use cases, offering:
- Public and private network compatibility
- Multiple consensus algorithms
- Enterprise-focused privacy features
- Integration with Ethereum mainnet
- Advanced monitoring capabilities
Hyperledger Sawtooth
A modular platform for building, deploying, and running distributed ledgers, featuring:
- Proof of Elapsed Time (PoET) consensus
- Transaction family abstraction
- Support for both Python and JavaScript
- Dynamic consensus mechanisms
- Enterprise-grade security
Core Components
1. Consensus Mechanism
Hyperledger frameworks support various consensus protocols:
- Practical Byzantine Fault Tolerance (PBFT)
- Proof of Elapsed Time (PoET)
- Raft
- Kafka-based ordering Each can be chosen based on specific business requirements.
2. Smart Contracts
Called “chaincode” in Fabric, smart contracts in Hyperledger:
- Can be written in multiple programming languages
- Support complex business logic
- Enable automated execution of agreements
- Provide guaranteed outcomes
- Maintain transaction privacy
3. Privacy and Permissions
Enterprise-grade privacy features include:
- Private channels for confidential transactions
- Zero-knowledge proofs
- Identity management
- Role-based access control
- Data segregation capabilities
