Why is IPFS Essential for Blockchain?
Protocol Labs invented the Interplanetary File System (IPFS) as a peer-to-peer file sharing system. This system stores and accesses files, websites, applications, and data. It uses content-addressing to identify every file in a global namespace connecting all computing devices. Peer-to-peer file sharing with IPFS allows users to host and receive content in a decentralized manner. this means that users hold a portion of the overall data, resulting in a secure system for storing and sharing data. Users can serve files...

What is PostgreSQL and Why is it so Useful?
This article focuses on one of the most useful and important databases in the IT industry and that is PostgreSQL. This open-source database is an advanced, enterprise-class relational database that supports SQL (relational) and JSON (non-relational) queries. This database management system has been developed by its community for over 20 years, which has contributed to its high levels of accuracy, integrity, and resilience. Many web, mobile, geospatial, and analytics applications utilize PostgreSQL as their primary data store or warehouse. A...

Decentralizaed Oracle vs. Centralized Oracle
The blockchain oracle connects blockchains to external systems, enabling smart contracts to execute based on real-world inputs and outputs. Oracles allow decentralized Web3 ecosystems to access existing data sources, legacy systems, and advanced computations. With decentralized oracle networks (DONs), advanced decentralized applications (dApps) can interact with traditional systems by combining on-chain code with off-chain infrastructure. In this article, we will see how a blockchain oracle works, how it makes blockchain systems more secure, and also compare it with a non-blockchain...

Introduction to Tron Network and Its Features
The TRON (TRX) network is committed to advancing the decentralization of the internet by using blockchain technology and DApps. Since the launch of its mainnet in May 2018, this network, founded in September 2017 by Justin Sun, has maintained its outstanding performance. With over 100 million monthly active users, BitTorrent, a pioneer in decentralized services, was acquired and integrated into TRON in July 2018. This blockchain is also the largest circulating supply of stablecoins in the world, surpassing Tether (USDT)...

What is DoS Attack and How to Prevent it?
Denial-of-Service attacks (DoS) shut down a machine or network by flooding it with traffic or sending information that triggers it to crash, preventing its users from accessing it. DoS attacks accomplish this by flooding the target with traffic. The DoS attack robs legitimate users (e.g. employees, members, or account holders) of the services or resources they expect. Often, DoS attacks target the web servers of high-profile organizations, such as banks, commerce, and media firms, as well as government agencies and...

Why is Kubernetes an Important Tool ?
Kubernetes also known as "K8s", automates the deployment and management of cloud-native applications by orchestrating containerized applications running on a cluster of hosts. With this tool, workloads are distributed across a cluster and dynamic container networking is automated. It allocates storage and persistent volumes to running containers, scales automatically, and continuously maintains the desired state of applications, providing resilience. The Kubernetes platform is an open-source platform for managing containerized workloads and services. It facilitates declarative configuration as well as automation....

What is SQL Injection and How should we Prevent it?
The SQL injection attack involves manipulating backend databases with malicious SQL code in order to gain access to information that wasn't meant to be displayed. This information includes sensitive company data, user lists, and private customer information. A successful SQL injection can have a far-reaching impact on a business. In some cases, an attacker may gain administrative rights to a database if they successfully view user lists, delete entire tables, or gain access to entire databases. These things are highly...

What is WSGI and Why is it necessary?
WSGI is a specification for how a server and application communicate. Both the server interface, as well as the application interface, are specified in PEP 3333. A WSGI application (or framework or toolkit) can be stacked on any server that conforms to the WSGI specification. These applications are compatible with each other. A middleware piece must implement both sides of the WSGI interface: the application on top, and the application below. For a middleware piece to be a middleware piece,...
