Blockchain Explained: What Is Blockchain?


Blockchain is a technology that allows individuals and companies to make instantaneous Digital Transformation companies on a network without any middlemen like banks. Transactions made on blockchain are completely secure, and, by a function of blockchain technology, are kept as a record of what happened. Strong computer codes ensure that no record of a transaction on a blockchain can be altered after the fact.
Here’s a more in-depth look at what a blockchain looks like.

 Blockchain Explained: A Visualization of How It Works
Funnily enough, you can explain a blockchain as literally a chain of blocks. Those blocks represent data, held all together in a specific order. You can also imagine it as a ledger—because that’s essentially how most blockchains function. Each block of data represents some new transaction on the ledger, whether that means a contract or a sale or whatever else you’d use a ledger for.
A blockchain is a record of transactions. Using blockchain, companies or people can both make and verify these transactions. That’s two very important concepts lumped together, so let’s take a closer look. Blockchain allows companies to make transactions.
Blockchain allows companies to verify transactions. Adding a transaction to a blockchain involves getting it verified. Whatever your “network” is, everyone will have agreed to rules that determine which transactions are valid and which are not.
This “democratic” system of security is one of the biggest reasons why so many people are flocking to blockchain right now. No one can change the records, so blockchain is a trustworthy and fair source of information that anyone can verify.
Blockchain is instantaneous. Transactions on a blockchain get processed and verified much more quickly than the alternative systems. This might seem counterintuitive because the lemonade example makes it sound like everyone has to copy everything that happens to the chain. But in actuality, these transactions get processed by computers in milliseconds. The reason why blockchain is much faster than the alternative is that it’s decentralized, so let’s talk about that to finish off the definition.
Blockchain Is decentralized. Blockchain operates with no central authority. This is the kicker. Blockchain lets people or companies add and verify their transactions, without a single governing body making sure everything is okay.
Blockchain technology essentially cut out the middleman. When one copy of the blockchain ledger gets changed, they all verify that transaction before adding it to their ledgers. And blockchain is faster than the alternative because everybody involved doesn’t have to wait on a single, slow-moving source for verification. It all happens simultaneously. By now, you’ve got the run-down on blockchain explained. It’s not too complicated, even though it sounds convoluted.
So far, we’ve got that a blockchain is a digital ledger shared between a network of people. Each participant can manipulate that ledger, recording new blocks of data onto the chain, but with each transaction, the entire chain gets analyzed by everyone to make sure it’s still accurate. In other words, everyone has their copy of the ledger. But nobody can make a change without everyone agreeing to it. It’s a democratic system.

That’s Blockchain Explained, But Who Uses It?
Here’s some industries looking to incorporate blockchain technology:
Banks and financial services are using blockchain to cut out the middlemen and a lot of time, money, and risk when dealing with monetary transactions. Industries that are high risk for fraud are starting to use blockchain to verify their software. A few companies are implementing blockchain to prevent the false certification or sale of blood diamonds and stolen art, for example.
Digital content like music, movies, and online ads could use blockchain to prevent piracy. By using new file formats that can play the media and encode blockchain data that reflects intellectual property and payment history, musicians and filmmakers wouldn’t be losing out on millions.
In medicine, blockchain technology can be used to prevent the theft of pills through the supply chain and give medical history ownership back to patients (who can distribute it to their doctors, for certain amounts of time, as they want or need).
In the food and drink industry, farmers could use blockchain to monitor their crops—and trace where and when food recalls occur.
Insurance could be dramatically changed. Imagine a world where you can get the insurance that lasts for a few hours, like if you’re doing some extreme sport. Or where Uber drivers can bypass insurance companies by combining their money on a blockchain and creating a safety net for themselves.
Blockchain is a development that lends itself to creativity, so we’ll likely see some very interesting uses in the future. Whether you’re an individual or a multinational company selling and buying, each transaction you add to the blockchain is checked against everyone else’s blockchain ledgers. This system prevents anyone from using the same bitcoin more than once—which was the biggest problem with all-digital currencies before bitcoin came along.
Since bitcoin is a purely person-to-person digital currency model, anyone using bitcoin can make fast, secure, low-fee transactions whenever they want, to anyone in the world. It’s a universal currency.
Hopefully, now you’ve got a solid grasp on what blockchain is, why everyone’s talking about it, and how it can impact your small business. Whether or not you decide to accept bitcoins as a form of payment depends on you and your small business needs.
