There's no such thing as a 'Tron witness' on the STEEM blockchain. Sure, someone representing Tron can become a witness here, but that makes them a STEEM witness. Someone representing Steemit Inc can become a witness, but that does not make them a 'Steemit witness.' Yabapmatt is not a 'Splinterlands witness'. Dan Larimer could pop back in and fire up a witness, but that would not make him an 'EOS witness'. Catch my drift?
