What Is Blockchain Technology And Why Should You Care?


You’ve probably heard the term “blockchain” thrown around a lot recently. You may even think it’s just some marketing buzzword, but it’s not: blockchain is here to stay and will shape the future of many industries. But what is blockchain technology? And how does it work? In this post, we’ll explain everything.

What is blockchain technology?

Let’s begin with the basics. Blockchain is a digital ledger that enables the secure transfer of information in a decentralized network. It’s also known as a distributed database and can be thought of as an open source internet protocol, similar to email or RSS feeds.

How blockchain works

  • Blockchain is a distributed ledger.
  • A blockchain is made up of blocks that are linked together through cryptography.
  • Each block contains transactions, and the links between them form the chain.
  • The blocks are added in chronological order, so if you know what time a transaction occurred or who sent it, you can follow along from there.

Blockchain in the real world

Blockchain is a decentralized database.

Blockchain is a shared ledger.

Block blockchain is a distributed ledger.

Blockchain is a consensus mechanism, which means everyone on the network has access to all of the data in that block and can see if it’s been tampered with or changed in any way (and they can also add new blocks of information). This makes it possible for transactions to be verified by multiple parties without having an intermediary like PayPal or Western Union involved as an intermediary between buyer and seller–or buyer and seller and supplier, etc., all the way down through all relevant parties until you get down to your payment processor who then pays out whatever amount was agreed upon before any actual goods were delivered/services rendered (and if there’s no agreement on price beforehand).

Blockchain explainer

Blockchain is a distributed database. It’s also a secure way to store data, and it’s the technology behind cryptocurrencies like Bitcoin and Ethereum.

Blockchain was created by Satoshi Nakamoto in 2008 as part of his white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” The idea behind blockchain is simple: instead of storing information on one server, it’s kept across multiple servers (or even thousands) at once–and those servers constantly update their information with each other so there’s no single point of failure or access. This makes it extremely difficult for hackers to gain access to any given piece of data within this system because they’d have to break into every single computer at once!

Blockchain technology has become a buzzword in recent years. But what exactly is it? In short, blockchain refers to a digital ledger that records transactions across many computers at once. Each transaction block is linked together in chronological order with other blocks–hence “blockchain.” The result is an immutable record of all activity on the network: no single party controls this information, as it’s stored on multiple machines within an ecosystem known as a peer-to-peer network (P2P).


Blockchain is the future of technology, and it’s here to stay. The blockchain technology is going to change the world as we know it.
