Even if you haven’t heard of Steem before, chances are, you’ve probably heard of cryptocurrency and blockchain technology. But how does it all work? A blockchain, by definition, is a decentralized and open ledger that records every economic transaction in real-time.
Imagine that every person has a spreadsheet that has information about every sale that has ever happened. As more sales occur, a computer updates each spreadsheet just as every sale occurs. This is what blockchain technology is.
For blockchain to work as it does, every block (a group of transactions) in the chain must be in agreement. Data cannot be corrupted because changing any information on the blockchain means that one computer would have to overpower an entire network, and this is almost impossible with a decentralized network.
