What is Blockchain?
What are some advantages of blockchains?
What’s the main advantage blockchains?
Think about how much of your financial life takes place online, from shopping to investing and how every single one of those transactions requires a bank or a credit card company or payment processor like Paypal in the middle of it.
Blockchains allow for those transactions to happen without a middleman, and without the added costs and complexity that come with them.
Is Bitcoin a blockchain?
Bitcoin is a form of digital money. And the underlying technology that makes it possible is a blockchain.
How many kinds of blockchains are there?
Thousands, from the ones that power Bitcoin, Litecoin, Tezos, and countless other digital currencies to an increasing number that have nothing to do with digital money
How does a blockchain work?
Picture a chain you might use for a ship’s anchor. But in this case, every link on the chain is a chunk of information that contains transaction data. At the top of the chain you see what happened today, and as you move down the chain you see older and older transactions. And if you follow it all the way down to the anchor sitting at the bottom of the harbor?
You’ll have seen every single transaction in the history of that cryptocurrency. Which gives the blockchain powerful security advantages: it’s an open, transparent record of a cryptocurrency’s entire history. If anyone tries to manipulate a transaction it will cause the link to break, and the entire network will see what happened. That, in a nutshell, is blockchain explained.
Who invented the blockchain?
A person or group using the name Satoshi Nakamoto published a whitepaper online explaining the principles behind a new kind of digital money called Bitcoin in late 2008. Every cryptocurrency since is an evolution of the ideas laid out in that paper.
What's the future of blockchains?
The blockchain idea has turned out to be a platform that a huge range of applications can be built on top of. It’s still a new and rapidly developing technology, but many experts have described blockchain’s potential to change the way we live and work as being similar to the potential public internet protocols like HTML had in the early days of the World Wide Web.

- They’re global: which means that cryptocurrencies can be sent across the planet quickly and cheaply.
- They increase privacy: Cryptocurrency payments don’t require you to include your personal information, which protects you from being hacked or having your identity stolen.
- They’re open: Because every single transaction on cryptocurrency networks is published publicly in the form of the blockchain, anyone can scrutinize them. That leaves no room for manipulation of transactions, changing the money supply, or adjusting the rules mid-game. The software that constitutes the core of these currencies is free and open-source so anyone can review the code.

Who invented the blockchain?
A person or group using the name Satoshi Nakamoto published a whitepaper online explaining the principles behind a new kind of digital money called Bitcoin in late 2008. Every cryptocurrency since is an evolution of the ideas laid out in that paper.
- Nakamoto’s goal was to create digital money that would make online transactions between two strangers anywhere in the world possible without requiring a third party like a credit card company or a payment processor like Paypal in the middle.
- This required a system that would eliminate a thorny issue called the ‘double spending’ problem, where a person might use the same money more than once. The solution is a network that is constantly verifying the movement of Bitcoin. That network is the blockchain.
- Every Bitcoin transaction is stored and verified by a global network of computers beyond the control of any person, company, or country.
- The database that holds all of that information is called the blockchain. Bitcoins are ‘mined’ via that huge, decentralized (also known as peer-to-peer) network of computers, which are also constantly verifying and securing the accuracy of the blockchain. In exchange for contributing their computing power to the blockchain, miners are rewarded with small amounts of cryptocurrency.
- Every single bitcoin transaction is reflected on the ledger, with new information periodically gathered together in a “block,” which is added to all the blocks that came before.
- The miners’ collective computing power is used to ensure the accuracy of the ever-growing ledger. Bitcoin can’t exist separately from the blockchain; each new bitcoin is recorded on it, as is each subsequent transaction with all existing coins.
