Blockchain Identity Network with Hyperledger Indy & Docker | Full Setup Tutorial | Chapter 01

Описание: In this episode, we dive deep into building a complete Blockchain-based Decentralized Identity (SSI) system using Hyperledger Indy and Docker.

This video provides a hands-on tutorial for setting up a decentralized identity network using Hyperledger Indy and Docker. It uses the von-network open-source repository to simulate a blockchain environment locally for development and testing.

Core Concepts & Architecture (0:52 - 4:09)
The instructor explains the foundational infrastructure of a decentralized identity system:

Four-Node Network: In this local setup, four Docker containers represent separate validator nodes.
Personas: The network involves multiple roles, primarily Trustees (network owners), Stewards (node operators), and Endorsers.
Web Ledger: A browser-based explorer (running on localhost:9000) allows you to visualize transactions, schemas, and DIDs (Decentralized Identifiers).
Pool & Wallet: A gateway that allows clients to interact with the ledger to generate credentials.
Technical Setup & Configuration (6:00 - 14:21)
The tutorial walks through the repository structure and prerequisites:

Environment: The setup uses Ubuntu 20.04 via WSL (Windows Subsystem for Linux) and Docker.
Genesis File: Explains that this file contains the initial transactions needed to boot the blockchain (8:36).
Networking: Each node requires two ports: one for internal node-to-node communication and one for client interaction (9:12).
Manage Script: A crucial utility script used to build, start, stop, and clean up the network (11:01).
Practical Demonstration (15:13 - 21:26)
The instructor demonstrates how to manage the network lifecycle:

Starting the Network: Using the command ./manage start to spin up the containers and the web UI.
Registering Identities: Shows how to register a new DID (e.g., Bob as an Endorser) via the Ledger UI and confirms the transaction in the domain ledger (17:03).
Managing Persistence:
Stop: Halts containers but keeps data intact (20:35).
Down: Removes containers and volumes, effectively wiping the ledger data for a fresh start (21:35).
Troubleshooting & Logs (19:51 - 25:51)
Logs: The instructor emphasizes using ./manage logs to monitor node syncing and troubleshoot errors (19:55).
Validation: By checking the transaction count on the Web Ledger, you can verify if the network has successfully recovered from a restart or been completely reset (26:00).
