How Blockchain Works & How Can It Be Used In Business

Introduction

For years, business leaders have been looking for the next big thing to transform their industries. And now, many believe that technology called blockchain has the potential to change how we do business forever. The idea behind blockchain is simple: it lets people exchange money or goods directly without relying on a third party such as a bank or government (and without having to worry about things like currency exchange fees). But what is blockchain exactly? How does it work? And why is everyone so excited about it? In this post, we’ll answer all those questions and more!

What is a Blockchain?

A blockchain is a shared, decentralized ledger that records transactions across many computers. A blockchain can be thought of as a type of database that maintains a continuously growing list of data records secured from tampering and revision. Each block contains information such as transactions and/or other relevant data (i.e., medical records) that has been verified by the network with time stamps.

When using the term “blockchain,” people usually refer to its application in cryptocurrencies like Bitcoin or Ethereum. However, there are many other potential uses for this technology besides digital currencies; for example:

  • Supply chain management – Blockchain technology can help companies track their products throughout the supply chain process so they can verify where each item came from and when it was manufactured. This prevents counterfeit goods from being sold at stores while also helping reduce waste due to expired food items being thrown away by consumers who don’t know whether they’re safe to eat after sitting on store shelves too long.*

How Does a Blockchain Work?

A blockchain is a distributed ledger. It’s decentralized, immutable and transparent. It’s permissioned, meaning that only certain people can access it; and it’s secure because the data is stored in blocks that are linked together using cryptography.

The first use of blockchain technology was for digital currencies like bitcoin but its uses go far beyond just currency transactions; there are many potential applications for businesses including supply chain management or even voting systems where votes can be recorded on a private blockchain system instead of relying on an election official to count them manually at polling stations (which has been shown to be prone to error).

The Cryptography of Blockchains

To understand how blockchain works and how it can be used in business, it’s important to understand the cryptography that underpins it. Cryptography is simply the science of keeping information secret or private. In a blockchain system, cryptography ensures that only authorized users can access data on the chain and make changes (if they have permission).

Cryptography has been used for centuries by governments and militaries around the world as an effective way of protecting sensitive information from being seen by unauthorized parties. The word “cryptography” comes from two Greek words: “kryptos,” meaning hidden; and graphia, meaning writing or inscription.

In modern times, cryptography has become even more powerful thanks to computer science advancements like public key infrastructure (PKI), which allows anyone who owns a particular private key pair–a sequence of numbers generated randomly–to digitally sign documents electronically without having access to any other information besides what’s needed for signing purposes itself; hash functions like SHA-256 which converts an input into another number with no way back into original input value because hashing algorithms are one-way functions where every output value depends completely unrelated previous state inputs so if someone changes even one bit in their input then whole output changes drastically too much so nobody could ever try guessing correct values given enough time since there are trillions trillion combinations possible even with just four bits per byte!

Decentralization in Blockchains

Decentralization is a key feature of blockchains, and it’s what makes them so powerful.

A blockchain is not controlled by any one entity; it’s decentralized, meaning that no single person or group has control over the system. This means that no one can stop the network from functioning, even if they wanted to (which they wouldn’t).

The concept of decentralization is central to why blockchains are so popular: It allows for secure systems without having to rely on third parties such as banks or governments who could potentially be compromised by hackers or other malicious actors looking to disrupt services provided by those institutions.

How Can You Use Blockchain Technology in Business?

Blockchain technology has the potential to revolutionize many industries, and business leaders are increasingly looking at how they can use it to improve their operations. Here are some examples of how blockchain can be used in business:

  • Tracking transactions – Blockchain allows you to track every transaction that occurs within your company or organization, making it easier to spot fraudulent activity. For example, if someone tries to charge an expense they shouldn’t have paid for (such as office supplies), your system will automatically flag the transaction as suspicious because it doesn’t line up with previous purchases made by that person. You can also use blockchain technology as part of a loyalty program by rewarding customers with points every time they make purchases using your store’s credit card or other approved payment methods; these points can then be redeemed for discounts on future purchases or rewards like free shipping when ordering online from other companies who accept cryptocurrencies such as Bitcoin Cash (BCH).
  • Managing supply chains – The term “supply chain” refers broadly speaking any process involving multiple parties working together toward achieving common goals–for example: manufacturing products then selling them through retailers such as Walmart or Target before finally reaching consumers’ homes via delivery services like UPS/FedEx/DHL etcetera…

Blockchain tech is still new, but it has the potential to change how we do business forever.

Blockchain tech is still new, but it has the potential to change how we do business forever.

Blockchain technology is one of those things that’s big enough to be important, but not so big that everyone knows what it is or how it works. And while many people have heard of blockchain and know a little bit about its potential uses in business and government applications–like cryptocurrencies like Bitcoin and Ethereum–fewer understand how the technology actually works.

Conclusion

Blockchain technology is still new, but it has the potential to change how we do business forever. The technology is already being used by some companies in different industries, from music streaming services like Spotify or Pandora to retail giants like Walmart and Target. With all of these examples showing how blockchain can be used in real life situations, it’s clear that this technology will continue growing as time goes on!
