Introduction
Blockchain is a digital ledger that chronicles transactions and events in a decentralized way. The blockchain technology was first developed to track Bitcoin transactions, but its uses have expanded into many other areas. Blockchain can be used by businesses to improve their efficiency, reduce costs and increase revenue through cutting-edge technology.

The blockchain is a digital ledger that chronicles transactions and events in a decentralized way. It's been around since 2008, but it's really only been recently that people have started paying attention to its potential for use in business.
Blockchain technology can be used for everything from tracking inventory at your retail store to making sure your customers are getting what they paid for when they purchase something online. And it doesn't stop there—the possibilities are endless! Let’s take a look at how exactly the blockchain works so you know what opportunities might open up if you choose this technology over others:
Cryptocurrency
Cryptocurrency is a digital currency that can be transferred between parties without the need for a third party. It does not rely on banks or governments to function and is often used to pay for goods and services online.
Cryptocurrency was created in 2009 with the release of Bitcoin, one of the first cryptocurrencies ever created. Since then, thousands more have been developed as part of an ongoing effort to improve upon this model by creating new innovations based on blockchain technology (see below). Each cryptocurrency has its own unique set of rules about how it works—and these rules may vary widely from one coin to another.
Smart Contracts
Smart contracts are computer codes that execute the terms of a contract when they're triggered. For example, if you buy something from Amazon and it doesn't arrive on time (or at all), your money will be refunded automatically.
Smart contracts are self-executing and self-enforcing; they don't need a middleman like a bank or government to enforce them, because they can be programmed to do so themselves through blockchain technology. This gives smart contracts their decentralized nature—they don't depend on one entity controlling them for their existence!
Decentralized Applications (DApp)
Decentralized Applications (DApps) are applications that run on the blockchain, making them decentralized. This means that they are not controlled by one entity and can be accessed by anyone with an internet connection. They’re open source, so anyone can modify them or build upon their functionality without needing to ask permission from any company.
DApps have become popular because they offer many benefits over traditional software: you don’t need to pay for licenses or subscriptions; there are no limitations on how many copies of the software you can use; it is cheaper than hiring developers; updates happen quickly because all changes are made through peer-to-peer transactions rather than being posted publicly like other apps do (which requires approval); DApps work across different operating systems and devices such as smartphones, tablets, laptops/desktops etc...
Private Blockchains vs Public Blockchains
Private blockchains are owned by a single entity, such as a company or government agency. They can be used for business transactions and other functions that require confidentiality. Public blockchains, on the other hand, are open to anyone who wants to use them—you don't need permission from anyone before you join one of these networks (although there may be certain restrictions depending on the particular network).
If you're working with your company's internal data in addition to external parties like vendors or customers, it makes sense for your blockchain network type to match this requirement: if you're only sharing information within your organization then a private blockchain would be perfect; if however everyone needs access at all times then public access might not suffice anymore.
Consensus Algorithms
Consensus algorithms are used to determine the validity of a block in the blockchain. They come in different varieties, but all have one thing in common: they use a majority vote to reach consensus on whether or not a new transaction should be added to their respective ledgers.
The most popular form of consensus algorithm is Proof-of-Work (PoW) which requires miners to solve puzzles using computational power and electricity as incentives for participation. The more difficult it is for miners, the more expensive it becomes for them to participate; however, this also makes them more likely candidates if you want high levels of security and reliability when it comes into question whether or not something has happened on your network because there won't be any way anyone could hack into them since they're working 100% autonomously without any human intervention whatsoever!
There are a few distinct sorts of blockchains, each with its own remarkable highlights.
Blockchain is a distributed ledger. In other words, it's a shared database that records transactions in chronological order across multiple computers at once. The blockchain's decentralized nature allows for anyone to access the data on this shared ledger and make changes to it—even if those people aren't part of your company or network (which means they don't need permission from you). The result? A more secure way of keeping track of transactions than ever before!
