There is a miner (like bitcoin) inside the bundled JS files!

You can search for mined word in the _shared-web-resources/autobahn/autobahn.js (and .min.js as well) and find various references to some sort of miner:

• // time out the transaction if not mined after 50 blocks
• Transaction was not mined within
• ...

This was introduced with the latest commit aa3afbe from @om26er

@frol, The autobahn-js library implemented the XBR protocol (which uses web3, etherium stuff) crossbario/autobahn-js#424, its not a miner and is not supposed to do anything unless specifically used.

The lines you found come from https://github.com/ethereum/web3.js

Ah, false alarm. Sorry :)
