Despite its appearance, blockchain is relatively simple in principle. A blockchain may be of as a special kind of database. To comprehend blockchain, one must first grasp the concept of a database. When we talk about databases, we mean a collection of electronically recorded data on a computer network. Database information is in the table style.
Instead of a database, what’s the difference between utilizing a spreadsheet? For a small number of individuals, spreadsheets are the best way to keep and share modest quantities of data. On the other hand, a database is in use to accommodate far more significant volumes of data and allow for easy access, filtering, and manipulation by a large number of people at the same time.

Structure for Keeping Things
The “blockchain” is a chain with data made up of blocks with varying storage capacities linked together when one is complete. After that, they add all new information into a newly created partnership, which is subsequently added to the chain once complete. Unlike a database, which organizes its data into tables, a blockchain contains its data into contiguous chunks (blocks).
All blockchains are also databases, though not all data sets are blockchains due to this discovery. When deployed in a decentralized manner, this technology also creates an irreversible chronology of data. As soon as a block is complete, it becomes a permanent fixture in the timeline. They add a new block to the chain, and they assign an accurate timestamp to each one.
It’s helpful to look at blockchain in light of Litecoin implementation to grasp it better. This blockchain is nothing more than a special kind of database for Bitcoin, which records every transaction done with the digital currency. It is important to note that in the case of Bitcoin, and contrast to other databases, the computers are also not all under the same roof and are each controlled by a different individual life individually.
This business owns a warehouse where most of these computers are under one roof. And it has complete access to all of the data on each of those machines. Hundreds of computers make up Bitcoin’s blockchain, but each one is at a different geographical location, and another person or group of people runs it. In the Bitcoin world, these machines are known as nodes since they form the network. In this strategy, we use the decentralized blockchain of Bitcoin. It is possible to have a centralized private blockchain owned and administered by such a single entity, although rare.
Bitcoin’s blockchain is decentralized, which means that anybody may observe all transactions in real-time by running an individual node or by utilizing blockchain explorers. As new blocks are validated and added, a copy of the chain is on each node.
As a result, if you so desired, you could follow Bitcoin’s every move. The hacker may be completely anonymous, yet the Bitcoins they stole are identifiable. Those who are hacking targets would know if any of their Bitcoins have been transferred or spent.
Is it Safe to use blockchain?
Security and trust concerns are addressed in many ways by blockchain technology. They keep all new blocks chronologically and linearly. To put it another way, they’re always at the “very end” of the chain. Look at the Bitcoin blockchain, and you’ll find that each chunk has a “height” on the chain. The block’s height has grown to 656,197 blocks by November 2020.
Once a block is on to the chain, it is also very impossible to reverse and make changes to the block’s contents without the support of the majority. Due to the block’s hash and the preceding block’s hash, in addition to the time stamp already mentioned, each block has its unique hash. Hash codes scramble digital data into a random list of numbers and characters.
The hash values are in modifying process change in any manner. Think about it this way: suppose a hacker wants to improve the blockchain to take everyone’s Bitcoin for himself. If they made any changes to their single copy, it’d throw off the alignment of the other documents.
