In this article, you’ll learn more about blockchain. This is the first step in your cryptocurrency journey; you must first understand the basic facts about blockchain in order to fully understand and know how it works, so once you’ve learned more about blockchain, it will be easier for you to become acquainted with cryptocurrencies as well.

The article will cover topics such as:

  • What is blockchain in simple words?
  • What is blockchain used for?
  • What is the blockchain and how does it work?
  • What is a blockchain example?

What is blockchain in simple words? 

A blockchain is a distributed database that is shared among computer network nodes. Blockchain, like a database, stores information electronically in digital format. A blockchain collects information in groups known as blocks, which hold sets of data. When a block’s storage capacity is reached, it is linked to the previously filled block, forming a data chain known as the blockchain.

Blockchain is a type of shared database that stores information differently than traditional databases. In the case of Bitcoin, the blockchain is used decentralized, so that no single person or group has control. This means that all transactions are permanently recorded and accessible to anyone. Because decentralized blockchains are immutable, the data entered is irreversible. Once the block has been filled with data, it is chained onto the previous block, resulting in the data being chained together in chronological order.

What is blockchain used for? 

Blockchain can be used for data reports on sales, tracking, digital use, and cross-border payments. It can also be used on IoT devices that generate large amounts of data that must be stored and processed. You can also use blockchain to keep track of what nfts you’ve purchased with a crypto wallet. 

Blockchain is essentially a massive database that allows people to remain anonymous while also allowing people to view blockchain transactions. Blockchain has many use cases and a broad purpose; some large corporations are now implementing blockchain technology to improve workloads and strengthen work production. Who knows if it has been used to track covid cases, analyze covid data, and gather data information about it, or if it will be used to process data in space or capture data by NASA someday.

What is the blockchain and how does it work?

The first popular application to successfully use the blockchain was the cryptocurrency Bitcoin, which was launched in 2009. It is a type of distributed ledger technology (DLT), which is a digital system for simultaneously recording transactions and related data in multiple locations.

A blockchain is a digital system for simultaneously recording transactions and related data in multiple locations. Unlike traditional databases, which store data in rows, columns, tables, and files, blockchain stores data in blocks that are digitally chained together.

How does it work?

Blockchain also known as distributed ledger technology, works using the bitcoin system as an example. Bitcoin transactions are entered and transmitted to a network of powerful computers known as nodes. The sale is added to a block on the distributed ledger once it has been cryptographically confirmed. 

However, it was a 2008 paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System” by the pseudonymous Satoshi Nakamoto that brought an academic theory into real-world use. This is referred to as bitcoin mining.

How do the Ledger and a Block work?

Following the creation of the first block, each subsequent block in the ledger uses the previous block’s hash to calculate its own hash. Consensus ensures that all copies of the distributed ledger on the blockchain are in the same state. 

A block that has been added can be referenced in subsequent blocks, but it cannot be changed. If someone tries to swap out a block, the hashes for previous and subsequent blocks will also change, causing the shared state of the ledger to be disrupted. When consensus is no longer possible, other computers in the network are notified, and no new blocks are added to the chain until the issue is resolved.

What is a blockchain example?

There are many examples of blockchain, but the top on the list is:

  • Smart Contracts:

Smart Contracts was first used in 1993, but it has only recently gained popularity as a result of the release of the Ethereum Project in 2013. 

A smart contract is a self-executing contract that shows agreement between buyer and seller is directly written into lines of code. The code and the agreements contained therein exist across a distributed, decentralized blockchain network. 

It permits trusted transactions and agreements to be carried out among disparate, anonymous parties without the need for a central authority or enforcement mechanism which makes it a decentralized network.

  • Cloud Storage: Cloud storage will be available to businesses. Storj is an example of a company that provides secure cloud storage while reducing reliance. With cloud storage and blockchain technology, businesses can save money on physical hard drives.
