Overview / Abstract

Blockchain technology is emerging as a foundation for digital assets, tokenization platforms, central bank digital currencies (CBDCs), and multi-organizational business ecosystems. This tutorial introduces blockchain fundamentals and Hyperledger Fabric architecture, then examines performance engineering in enterprise deployments through DRUNIX, an enterprise-grade distributed-ledger platform developed as an enhanced fork of Hyperledger Fabric. Topics include benchmarking, bottlenecks, optimization techniques, and deployment strategies.

Target Audience

• Researchers working in distributed systems, blockchain, security, and performance engineering.
• Graduate students interested in enterprise blockchain systems.
• Industry practitioners involved in blockchain deployments, digital-asset platforms, and tokenization ecosystems.
• Software architects, platform engineers, DevOps engineers, and technology decision-makers evaluating enterprise blockchain solutions.

Prerequisites

No prior blockchain-implementation experience is required. A basic understanding of computer networks, distributed systems, databases, and software-architecture principles is beneficial. Linux, Docker, and command-line familiarity may benefit participants attending the demonstration.

Learning Outcomes

• Understand fundamental principles of blockchain and distributed-ledger technologies.
• Explain Hyperledger Fabric architecture and core components.
• Describe the transaction lifecycle, including endorsement, ordering, validation, and commitment.
• Analyze performance bottlenecks in enterprise blockchain networks.
• Evaluate infrastructure, database, networking, and consensus-related performance parameters.
• Understand DRUNIX architectural evolution and design principles.
• Apply techniques to improve throughput, reduce latency, and enhance scalability.
• Gain hands-on exposure to deployment, configuration, monitoring, and operations.
