Blockchains are today being used by government as well as corporate agencies because of the security, integrity and privacy they offer. These security features are provided by decentralised applications and smart contracts. Important applications of blockchain include cryptocurrencies, non-fungible tokens (NFTs), financial transactions, logistics management, e-governance, and many others.
Transaction logs associated with blockchain-based applications are secure and have no scope for hacking. Each and every record in the blockchain is linked to dynamic cryptography, enabling all transactions to be encrypted, thus eliminating the risk of sniffing or hacking.
The distributed ledger in a blockchain is a digital asset that has been copied, synced, and shared across several devices and locations to prevent manipulation by third parties. For instance, a bank can offer a better level of security if it uses distributed ledger technology. The records of the transactions will be kept on one million devices if that bank has a million customers. So instead of just one server, the hacker will have to break into one million devices simultaneously. This is the main benefit of utilising decentralised blockchain technology.
If hackers gain access to a bank’s server using a centralised application, they can copy all the customer information and data. That is the primary factor driving the decentralisation of webbased applications by government organisations.
Decentralised applications can be used to safeguard government servers that host land registry records, citizens’ data (including Aadhaar in India), permanent account numbers (PAN), and so on.

Helgrind: Detecting Synchronisation Issues in Multithreaded Programs
Let's explore how Helgrind can be used to detect and debug multithreading issues with the help of a multithreaded C program.
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.
From Virtual Machines to Docker Containers: The Evolution of Software Development
Containerisation and Kubernetes have eased software development, making it faster and better. Let's see where these are headed, looking at trends that are making life easier for developers.
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.
