A Blockchain is simply a global computer network that manages all movements of Cryptos from one peer to another using a shared database, or the Blockchain.
These computers are referred to as “miners” and they have the capacity to create and maintain their Blockchain.
They do that by validating and transmitting data that is published by all the users in the network, the so called “entries”. Each “entry” is unique and represents the amount of Cryptocurrency send to another peer.
It is singular and irreversible so that “double-spending” does not occur, and all “entries” remain always in the network for the purpose of checking each new “entry”. Over the past few years Blockchain Technology has changed dramatically.
