Too Long; Didn't Read

Aims to learn more about cryptocurrencies from an engineering perspective. Explains why cryptocurrency requires a decentralised currency to function in society. The most crucial aspect of blockchain security is the use of cryptographic techniques to prevent data manipulation. Cryptocurrencies are decentralised, meaning there can't be a centralised government or a central bank to oversee how money is used on a daily basis. We can't keep a central authority in our society, and therefore it is harder and harder to ensure that a currency is functioning and harder it is properly functioning.
