Lack of consolidated language file
Currently the error messages and other statements are all presented in-line throughout the code. They are all randomly written, depending on when they were added and by whom.

Example: hive_evaluator.cpp#L1933 / hive_evaluator.cpp#L1972 Almost the same message, different text.
Terminology/statements across repositories, statements and files should be equalized and consolidated as possible.
Additional errors handled by applications that build on Hive such as Condenser should likewise be drawn from the consolidated language file as they are also haphazardly written in-line, as in TransactionReducer.js, for example.
