How cryptocurrency works?

Just few know that the cyptocurrency project emanated as a side product of an invention by Satoshi Nakamoto. He is known for the invention of bitcoin which we all know today as the leading cryptocurrency, but Satoshi never intended to create a currency.

During his announcement, he declared that he created “Peer-to-Peer Electronic Cash System” which he said was something that failed to be created before the invention of digital cash. This was when he announced the release of Bitcoin which is an electronic cash system that makes use of a peer-to-peer system which helps to prevent spending twice during a transaction and not controlled by any central authority.

The decision to build this decentralized network gave the birth of cryptocurrency. To get digital cash one will need a payment system having accounts, transactions and balances, but major payment methods fail to solve the problem of double-spending which is simply the issue of spending the same amount of money twice which is a foul in the central server.

In the decentralized system, you will not be having the central server, therefore every part of the network will be needed for a transaction. To avoid a double-spending, there must be a consensus between the future balances which is usually done by a central authority.
