Fungibility means every coin is the same, or interchangeable.
Definition: In economics, fungibility is the property of a good or a commodity whose individual units are essentially interchangeable, and each of its parts is indistinguishable from another part.
We serialize the coins, because this is how we would transfer the data over the network.
Serialization is the process of converting data into a binary format.
In this lesson we learned:
- Coins can be created.
- Coins need to be validated.
- Coins can be written to disk.
- We understand how to make Coins, pass them as transfers to our class PNGCoin, validate those transfers, then write coins to disk.
