TLDR
Blockchains are made up of a network of computers (or nodes) that are essentially public databases of transactions where everyone can add to, or view, at any time. Instead of the data residing on a single centralized server, the data is copied across thousands and thousands of nodes worldwide, allowing each node access to this database of transactions. This is essentially what gives blockchains their decentralized nature. There is a mechanism in-built into all blockchains to help their network of users verify, and come to consensus (through voting) on, the new transactions being added to the document.via the TL;DR App
