I am not an expert but from what I gather from the whitepapers and watching Crypto Maniacs Worker Bee is the Governing token of the Hive Engine BlockChain. Worker Bee is also a mining token as it mines Bee. Bee is the official currency of the Hive Engine BlockChain. For example Hive Engine pays it's Witness Servers with Bee tokens. 👍
If you are asking for the specifics of How Worker Bee works that is beyond the scope of my current knowledge base. You might be able to get better info from the Worker Bee white paper.
