Programming Hyperledger Fabric

An enterprise blockchain or distributed ledger technology (DLT) is very much like a shared document stored on a cloud drive. There are just two differences. First, there is no master copy of this document stored with an escrow or arbiter, and second, any change to the document happens only after it has been signed off by all required stakeholders. This allows businesses to form a peer-to-peer network and establish a common ground of truth without giving up its control in hands of a single organization. The decentralized nature of the ledger combined with version control or immutability of the stored data is perfect for fast account reconciliation, secure tracking and tracing of products, and transparent records with no costly third-party auditing. This book teaches you how to build such decentralized applications.

What's Inside:

• Covers Fabric 2.0. Examples written in TypeScript and JavaScript
• Deploying to production across multiple nodes using Docker
• Securing communications with TLS
• Handling Data Privacy
• Comprehensive coverage of Fabric CA Server and Client
• Bonus chapters on Bitcoin and LDAP
• Digital Cryptography

about the technology

Hyperledger Fabric is a free, open source, and enterprise-grade framework for creating industrial blockchain applications. Fabric has been used to create invoice management, transparent insurance claims processes, and supply chain management applications for some of the world's biggest companies. Its flexible SDK simplifies many challenges of blockchain development, letting developers write smart contracts and build client applications in either Java, JavaScript, or Go.
