A mobile wallet doesn’t have data for the entire chain. How can you confirm that a transfer was actually included in a block?
When a block contains thousands of transactions, proving that one transaction is included takes only a dozen or so hashes—you don’t need to download all the transactions. This is crucial for mobile wallets.
There’s no homework for this lesson, but the market can test you at any time.
Markets are always full of surprises, so think ahead about what to do if your judgment turns out to be wrong.
