Blockchain technology has rapidly gained popularity across various industries for its secure and transparent nature. Hyperledger Fabric, one of the most prominent blockchain frameworks, stands out for its robust features and flexibility. Designed for enterprise use, it is part of the Hyperledger project hosted by The Linux Foundation and is one of the most popular blockchain frameworks for developing business applications.
How does it work?
At its core, Hyperledger Fabric works by creating a network of unique organisations that interact with each other. Each organisation has its own Fabric certificate authority (CA) and one or more peer nodes. The Fabric CA issues certificates for users and manages permissions, while peer nodes endorse transactions, execute smart contracts (Chaincode), and store a local copy of the ledger.
Transactions in Hyperledger Fabric are initiated by clients and endorsed by endorsing peers. These endorsed transactions are then ordered into blocks by the ordering service, which is shared by all organisations in the network. The ordering service ensures that transactions are properly ordered and broadcasts new blocks to peer nodes. Peer nodes validate the transactions in the block and update their local copy of the ledger accordingly.
Hyperledger Fabric as a blockchain framework
Hyperledger Fabric is a blockchain framework designed for developing enterprise-grade applications. It provides a modular architecture that allows organisations to customise various components, such as consensus algorithms, membership services, and smart contract execution environments.

The Perfect Process of Booting a PC
Booting a PC seems as simple as eating a cake. But are you aware of all that goes on behind-the-scenes to bake a delicious cake or seamlessly boot a PC?
Exploring eBPF and its Integration with Kubernetes
eBPF, a game-changing technology that extends the capabilities of the Linux kernel, offers significant advantages for Kubernetes networking. It also greatly improves Kubernetes observability by capturing detailed telemetry data directly from the kernel. Read on to find out how its integration with Kubernetes has immense benefits.
Deploying Generative AI LLMs on Docker
Built on massive datasets, large language models or LLMS are closely associated with generative Al. Integrating these models with Docker has quite a few advantages.
Containerisation: The Cornerstone of Multi-Cloud and Hybrid Cloud Success
Open source containerisation software provides the flexibility, cost-effectiveness, and community support needed to build and manage complex multi-cloud and hybrid cloud environments. By leveraging this software, businesses can unlock the full potential of multicloud and hybrid cloud architectures while minimising vendor lock-in risks.

India's Leap in Supercomputing: Innovating for Tomorrow
As India strides towards self-sufficiency in supercomputing, embracing this evolution isn't just an option-it is pivotal for global competitiveness and technological leadership.
SageMath: A Quick Introduction to Cybersecurity
In the previous articles in this SageMath series, we delved into graph theory and explored its applications using SageMath. In this seventh article in the series, it is time to shift our focus to another crucial subfield of computer science: cybersecurity and cryptography.
Efficient Prompt Engineering: Getting the Right Answers
OpenAl's GPT-3 and GPT-4 are powerful tools that can generate human-like text, answer questions, and provide insights. However, the quality of these outputs depends heavily on how you frame the input, or prompt. Efficient prompt engineering ensures you get the right answers by designing inputs that guide the AI towards relevant, clear, and useful responses. Let's find out how to craft effective prompts with examples.
Analysing Linus Torvald's Critique of Docker
This article looks at Docker's security flaws, particularly its shared-kernel model, and contrasts it with traditional VMs for better isolation. It discusses Linus Torvalds' concerns, explores mitigation techniques, and proposes a roadmap for building a more secure containerisation platform using hardware-assisted virtualisation, true isolation, and a robust orchestration layer.
