How a blockchain works
Welcome! I am excited to help you demystify how blockchain works. Before we dive into the technology, I'd love to know a bit more about your background so we can make this session as useful as possible.
I know a little bit about basic tech and business concepts, but not blockchain.
It is great to have you here! Since you already understand basic business and tech concepts, you will find that blockchain is really just a new way of keeping records.
Let's display our learning roadmap so you can see exactly where we are heading today.

The Decentralized Ledger
To understand blockchain, it helps to start with a concept you are likely already familiar with: a ledger. In business, a ledger is simply a book or a digital file used to record transactions, like who paid whom and how much.
Traditionally, these ledgers are central. For example, if you send money to a friend, a central bank holds the master ledger, verifies your balance, and updates the records.
But a blockchain is a . Instead of one central bank keeping track, copies of this exact same ledger are shared across a massive, global network of computers.
