This document introduces Hyperledger, an open source collaborative effort to advance blockchain technologies hosted by The Linux Foundation. It is a global collaboration across multiple industries. Hyperledger includes several frameworks like Hyperledger Fabric, an advanced blockchain framework from IBM. Hyperledger Fabric allows for private transactions and confidential smart contracts through channels and modularity. It also offers features for identity management, privacy, and efficient transaction processing. The document compares Hyperledger to Bitcoin's blockchain and outlines Hyperledger Fabric's architecture, including how applications, peers, chaincode, and the ledger interact through APIs and transactions.

• Private and permissioned blockchain.
• No miners or coins.
• Provides a modular framework that supports different
components for different uses.
• Other consensus schemes (membership services
provider), not proof-of-work computations. (SOLO, Kafka,
SBFT)
• Channel: allowing a group of participants to create a
separate ledger of transactions.

• Hyperledger Fabric is a one of the blockchain projects
within Hyperledger. Like other blockchain technologies,
it has a ledger, uses smart contracts, and is a system
by which participants manage their transactions.
• Hyperledger Fabric Capabilities
• Identity management
• Privacy and confidentiality
• Modular design
• Chaincode functionality
• Efficient processing

• Assets - Asset definitions enable the exchange of almost anything with monetary value over
the network, from whole foods to antique cars to currency futures.
• Chaincode - is software defining an asset or assets, and the transaction instructions for
modifying the asset(s). In other words, it’s the business logic.
• Ledger Features - The immutable, shared ledger encodes the entire transaction history for
each channel, and includes SQL-like query capability for efficient auditing and dispute
resolution.
• Privacy through Channels - Channels enable multi-lateral transactions with the high degrees
of privacy and confidentiality required by competing businesses and regulated industries that
exchange assets on a common network.
• Security & Membership Services - Permissioned membership provides a trusted blockchain
network, where participants know that all transactions can be detected and traced by
authorized regulators and auditors.
• Consensus - a unique approach to consensus enables the flexibility and scalability needed for
the enterprise.
