Becoming a Hyperledger Aries Developer (LFS173)

Develop blockchain-based production-ready identity applications with Hyperledger Aries.



Course Overview

Data is driving our world today. However, we hear about Data breaches and Identity thefts all the time. Trust on the Internet is broken, and it needs to be fixed. As such, it is imperative that we adopt a new approach to identity management, and ensure data security and user privacy through tamper-proof transactions and infrastructures.

Blockchain-based identity management is revolutionizing this space. The tools, libraries, and reusable components that come with the three open source Hyperledger projects, Aries, Indy and Ursa, provide a foundation for distributed applications built on authentic data using a distributed ledger, purpose-built for decentralized identity.

This course focuses on building applications on top of Hyperledger Aries components—the area where you, as a Self-Sovereign identity (SSI) application developer, can have the most impact. While you need a good understanding of Indy (and other ledger/verifiable credential technologies) and a basic idea of what Ursa (the underlying cryptography) is and does, Aries is where you need to dig deep.
