What’s Layer 2 all about? Don’t worry, your class rep is here:
Layer 2 refers to scaling networks built on top of the Ethereum mainnet. They execute transactions off-chain, then submit the results to the mainnet.
Layer 2 is cheaper because it bundles lots of transactions together and writes them back to the mainnet in one go, so those transactions share the mainnet fees.
I used to not understand this, and wasted enough money to enjoy several hot pot meals.
