How long does a transaction have to wait before it can no longer be reversed? Don't worry—the class rep is here to explain:
Ethereum blocks generally enter the “finalized” state after two epochs (about 12.8 minutes).
Probabilistic finality is like a stack of paper that gets taller and taller: the more paper piled on top, the harder it is to pull out the sheet at the bottom. Deterministic finality is more like a signed contract—once it's signed, there's no going back.
When I first started out, I thought understanding candlestick charts was all I needed. Turns out, the rules are lesson one.
