You may have heard the terms “blockchain” and “cryptocurrency” before, but what do they actually mean? In short, blockchain is a distributed database that allows for secure, transparent and tamper-proof transactions. Cryptocurrency is a digital or virtual currency that uses cryptography for security. While blockchain and cryptocurrency are often used interchangeably, they are two different things. In this blog post, we will explore the basics of both blockchain and cryptocurrency so that you can better understand how they work.
Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control.
The first blockchain was created by Satoshi Nakamoto in 2009 to serve as the public transaction ledger of the cryptocurrency bitcoin. Nakamoto described bitcoin as "a system for electronic transactions without relying on trust". The bitcoin blockchain is a public ledger that records bitcoin transactions. It is implemented as a chain of blocks, each block containing a hash of the previous block up to the genesis block of the chain. Transactions are verified by network nodes through cryptography and recorded in a public dispersed ledger called a blockchain.
Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. Bitcoin, the first and most well-known cryptocurrency, was created in 2009. Cryptocurrencies are often traded on decentralized exchanges and can also be used to purchase goods and services.
