What are the advantages of blockchain?

Global: Cryptocurrencies can be sent around the world.

Open: Because every transaction on a cryptocurrency network is published publicly in the form of a blockchain, anyone can review it. This leaves no room for manipulating transactions, changing the money supply, or adjusting the rules mid-run. The software that makes up the core of Bitcoin is free and open source, so anyone can review the code.

What are the main advantages of blockchain over the old financial system?

Think about how much of your financial life (from shopping to investing) takes place online, and how every transaction in it requires a bank or credit card company or payment processor like Paypal to process it in the middle. Blockchain can make these transactions happen without a middleman and the additional costs and complexities that come with it.

Is Bitcoin a blockchain? Bitcoin is a digital currency. And the underlying technology that makes it possible is blockchain.

How many blockchains are there, from the thousands that support Bitcoin, Litecoin, Tezos, and countless other digital currencies, to the growing number of currencies that have nothing to do with digital currencies.
