What Is Blockchain? The Technology Behind Cryptocurrency, Explained

As blockchain technology evolves and becomes more user-friendly, it is up to you to learn about it to be prepared for the future. If you are new to blockchain, this is the opportunity for you to learn the fundamentals. This article will explain to you how to answer the question, “What is blockchain technology?” You will also discover how blockchain works and why it is so important.

What Exactly Is Blockchain?

A blockchain is a distributed ledger that is exchanged among computer network nodes. A blockchain, like a database, saves information electronically in digital format. Blockchains are well known for their critical function in cryptocurrency systems such as Bitcoin in keeping a secure and decentralized record of transactions. The blockchain’s innovation ensures the accuracy and security of a data record and produces trust without the requirement for a trusted third party.

The way data is structured significantly within a regular database and a blockchain. A blockchain gathers information in groups known as “blocks” that contain sets of information.
When a block’s storage capacity is reached, it is closed and linked to the previously filled block, producing a data chain known as the “blockchain.” All new information that follows that recently added block is compiled into a newly composed block, then added to the chain once it is finished.

A database typically organizes its data into tables, whereas a blockchain, as the name implies, organizes its data into chunks (blocks) linked together. When implemented in a decentralized manner, this data structure creates an irreversible chronology of data. When a block is created, it is imprinted in stone and becomes a part of this chronology. When a block is added to the chain, it is indicated a specific timestamp.
