Introduction
I had a job interview in 2014 where I was asked what is Bitcoin. All I could say back then was that Bitcoin was “Internet Pirate Gold” because of a documentary I had seen on the Silk Road. Fortunately my answer was satisfactory at the time and I got the job. Throughout the next few years I would learn more about the blockchain.
In a nutshell:
Bitcoin allows for a number to be securely transferred between addresses. The sender subtracts this number from their total and the receiver adds this number to their total. There is a rule that prevents the sender from sending a number larger than their total.Ethereum allows for more complex logic to be securely carried out. Various applications can be built and a range of different types of tokens can be created and transferred, such as an NFT.
Both Bitcoin and Ethereum use a blockchain for security reasons, however this comes at a huge computing cost and so high fees are needed to complete transactions securely.
