Ethereum is much more than just a cryptocurrency. Bitcoin is primarily a digital currency, but Ethereum is a whole decentralized platform that runs smart contracts. Its cryptocurrency, Ether (ETH), is just one part of it.

Decentralized platform? Smart contracts? You’ve already lost me.

Okay, let me simplify. Ethereum is like a giant, global computer that anyone can use. It’s not owned by a single company or government. And smart contracts are self-executing programs that run on this computer.

Wait, programs? What kind of programs are we talking about?

Imagine programs that automatically handle agreements without needing a middleman. For example, let’s say I want to sell you something. A smart contract can ensure you only get the item if you pay, and I only get paid if you receive the item. No need for a third party like a lawyer or an escrow service.

Yep, anyone with a computer and the necessary software. But it’s resource-intensive, so not everyone does it. Nodes ensure the system stays secure and trustless.

So, anyone can become one of these nodes?
