What is blockchain technology?
You've likely heard some of the following terms if you've paid attention to the world of finance: Cryptocurrency, Blockchain, Bitcoin, Bitcoin Cash, and Ethereum. But what do they mean? And why is cryptocurrency suddenly so hot?
First, we'll explain the blockchain basics.
As society become increasingly digital, financial services providers are looking to offer customers the same services to which they're accustomed, but in a more efficient, secure, and cost effective way.
The origins of blockchain are a bit nebulous. A person or group of people known by the pseudonym Satoshi Nakomoto invented and released the tech in 2009 as a way to digitally and anonymously send payments between two parties without needing a third party to verify the transaction. It was initially designed to facilitate, authorize, and log the transfer of bitcoins and other cryptocurrencies.
How does blockchain technology work?
Blockchain tech is actually rather easy to understand at its core. Essentially, it's a shared database populated with entries that must be confirmed and encrypted. Think of it as a kind of highly encrypted and verified shared Google Document, in which each entry in the sheet depends on a logical relationship to all its predecessors. Blockchain tech offers a way to securely and efficiently create a tamper-proof log of sensitive activity (anything from international money transfers to shareholder records).
Blockchain's conceptual framework and underlying code is useful for a variety of financial processes because of the potential it has to give companies a secure, digital alternative to banking processes that are typically bureaucratic, time-consuming, paper-heavy, and expensive.
What are cryptocurrencies?
Cryptocurrencies are essentially just digital money, digital tools of exchange that use cryptography and the aforementioned blockchain technology to facilitate secure and anonymous transactions. There had been several iterations of cryptocurrency over the years, but Bitcoin truly thrust cryptocurrencies forward in the late 2000s. There are thousands of cryptocurrencies floating out on the market now, but Bitcoin is far and away the most popular.
How do you mine cryptocurrency?
Bitcoin, Litecoin, Ethereum, and other cryptocurrencies don't just fall out of the sky. Like any other form of money, it takes work to produce them. And that work comes in the form of mining.
But let's take a step back. Satoshi Nakamoto, the founder of Bitcoin, ensured that there would ever only be 21 million Bitcoins in existence. He (or they) reached that figure by calculating that people would discover, or "mine," a certain number of blocks of transactions each day.
Every four years, the number of Bitcoins released in relation to the previous cycle gets reduced by 50%, along with the reward to miners for discovering new blocks. At the moment, that reward is 12.5 Bitcoins. Therefore, the total number of Bitcoins in circulation will approach 21 million but never actually reach that figure. This means Bitcoin will never experience inflation. The downside here is that a hack or cyberattack could be a disaster because it could erase Bitcoin wallets with little hope of getting the value back.
