Blockchain Technology: Easy Guide for Beginners
Introduction: What is Blockchain Technology? Blockchain is a digital ledger, where every entry is a "block" of data. The blocks are connected in a "chain." Data can't be altered once added, which means it's extremely secure and transparent. How does it work? When someone desires to make a transfer, it is forwarded to a group of computers (nodes). The computers verify it. When approved, data is saved in a block and added to the chain — it never goes away. Why is it so secure? Each block has a unique code and reference. This is virtually impossible to alter without altering all of the other blocks, and because everyone has a copy of the chain, it's simple to identify cheaters.
