What is Cryptocurrency?
Cryptocurrency is a type digital currency based on cryptographic mathematics and blockchain technology. Bitcoin is the first and most famous cryptocurrency although it was not planned for it to be a currency. Bitcoin was established to be ‘’A Peer-to-Peer Electronic Cash System’’ that is truly decentralized - having no central controlling authority.
In the 90s there were many attempts to invent digital cash, however, they all failed and Satoshi Nakamoto saw that all the centralized attempts were a failure so he tried something different he built the digital cash system without a central entity similar to a Peer-to-Peer network for file sharing such as Napster. After that decision a new cryptocurrency era was born.
Satoshi calculated that digital cash would need networks of payments with balances, accounts and transactions. However, there is one main problem that literally every payment network faces that is called double spending.
Double spending is when two or more people spend the same amount at the same time so there is no way of knowing which one is the first transaction. A decentralized network such as Bitcoin requires a number of verification confirmations of transactions before they are places on the blockchain. While this process is happening a double spend attack could occur.
In the cryptocurrency network only, miners will be allowed to confirm transactions, they do this by solving a cryptographic puzzle. They will spread them across the network when they take the transactions and validate them. After that, all the nodes within the network will be added to its database. When the transaction is successfully confirmed the miner will receive a reward and transaction. Additionally, once the transaction is confirmed it will become irreversible and unforgeable.
Principally, every cryptocurrency network is constructed on the absolute consensus of all the participants in regards to the validity of balances and transactions. Although, within the network, there are nodes if they disagree on a single balance the whole system would basically break. Nevertheless, there are rules programmed within the network to prevent this from occurring.
