  Blockchain Simplified  - 2025 - 1 Understanding Blockchain: A Revolutionary Digital Ledger At its core, blockchain is a digital system that securely records and stores data in linked units called “blocks.”  These blocks form a chain, creating an unbroken and transparent record of all transactions. The system ensures that the data is stored permanently in chronological order, meaning every transaction follows the previous one.  Once a block is filled with data, a new block is automatically generated, making blockchain an ever-expanding ledger. The decentralized nature of the blockchain ensures that no single entity has complete control, promoting transparency and trust among participants.   How Blockchain Evolved: A Timeline 1991: The Foundation Blockchain technology originated in 1991 when researchers Stuart Haber and W. Scott Stornetta sought a reliable way to timestamp digital files.  Their solution used cryptographic methods to ensure th...

  DATA ANALYTICS HISTORY OF DATA ANALYSIS Data analysis is rooted in statistics, which has a pretty long history. It is said that the beginning of statistics was marked in ancient Egypt as it took a periodic census for building pyramids.   Throughout history, statistics has played an important role for governments all across the world, for the creation of censuses, which were used for various governme ntal planning activities (including, of course, taxation). With the data collected, we can move on to the next step, which is the analysis of that data.   Data analysis is a process that begins with retrieving data from various sources and then analysing it with the goal of discovering beneficial information. For example, the analysis of population growth by district can help governments determine the number of hospitals that would be needed in a given area.                     ...
