About Crypto
If a bank or government isn’t involved, how is crypto secure? It’s secure because all transactions are vetted by a technology called a blockchain.
What are Cryptocurrencies?
At its core, cryptocurrency is typically decentralized digital money designed to be used over the internet. Bitcoin, which launched in 2008, was the first cryptocurrency, and it remains by far the biggest, most influential, and best-known. In the decade since, Bitcoin and other cryptocurrencies like Ethereum have grown as digital alternatives to money issued by governments.
What are the most popular Cryptocurrencies?
The most popular cryptocurrencies, by market capitalization, are Bitcoin, Ethereum, Bitcoin Cash and Litecoin. Other well-known cryptocurrencies include Tezos, EOS, and ZCash. Some are similar to Bitcoin. Others are based on different technologies, or have new features that allow them to do more than transfer value.

A cryptocurrency blockchain is similar to a bank’s balance sheet or ledger. Each currency has its own blockchain, which is an ongoing, constantly re-verified record of every single transaction ever made using that currency.
Unlike a bank’s ledger, a crypto blockchain is distributed across participants of the digital currency’s entire network.
No company, country, or third party is in control of it; and anyone can participate. A blockchain is a breakthrough technology only recently made possible through decades of computer science and mathematical innovations.
