In exchange for contributing their computing power to the blockchain, miners are rewarded with small amounts of cryptocurrency. Bitcoin can’t exist separately from the blockchain each new bitcoin is recorded on it, as is each subsequent transaction with all existing coins. The miners’ collective computing power is used to ensure the accuracy of the ever-growing ledger. In exchange for contributing their computing power to the blockchain, miners are rewarded with small amounts of cryptocurrency.Įvery 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. 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. The database that holds all of that information is called the blockchain. That network is the blockchain.Įvery Bitcoin transaction is stored and verified by a global network of computers beyond the control of any person, company, or country. The solution is a network that is constantly verifying the movement of Bitcoin. 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. 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. Every cryptocurrency since is an evolution of the ideas laid out in that paper. That means there is almost zero risk of your financial information being compromised, or your identity being stolen.Ī 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. When making a Bitcoin payment, for instance, you don’t need to provide any sensitive information. The list of transactions contained in the blockchain is fundamental for most cryptocurrencies because it enables secure payments to be made between people who don’t know each other without having to go through a third-party verifier like a bank.ĭue to the cryptographic nature of these networks, payments via blockchain can be more secure than standard debit/credit card transactions. Imagine a global, open alternative to every financial service you use today, accessible with little more than a smartphone and internet connection.Īlmost all cryptocurrencies, including Bitcoin, Ethereum, Bitcoin Cash, and Litecoin, are secured via blockchain networks. Which means their accuracy is constantly being verified by a huge amount of computing power. Cryptocurrencies and the blockchain technology that powers them make it possible to transfer value online without the need for a middleman like a bank or credit card company. The Bitcoin blockchain, for example, contains a record of every time someone sent or received bitcoin.
