I have two different projects. In one, the build/token.json file contains an unlinked_binary field. In the other, there's no unlinked_binary, but there's bytecode.
What's the difference between the two?

It's about Library Linking. To perform a call to an external or public function defined in a library the compiler must know the address of the library. If you do not provide it using the --libraries option, the compiler will insert a temporary address placeholder instead. You can do linking separately to eliminate these placeholders.
unlinked_binary is bytecode that still contains placeholders while bytecode is the final bytecode that does not have any and can actually be deployed.
