A type of technology that makes a blockchain faster and cheaper by "rolling up" many transactions into one.
It's a system of financial services built on the blockchain that doesn't need a central company like a bank.
Stands for "Ethereum Virtual Machine." It's the computer inside the Ethereum blockchain that runs smart contracts.
A virtual world you can enter and interact with, often with its own economy based on cryptocurrency.
Stands for "Non-Fungible Token." It's a unique digital item that can't be replaced, like a digital painting or a special video clip.
A rollup that assumes all transactions are correct and only checks them if someone proves they're not.
