I'm aware of BM's POW but it's in no way related to Bitcoin's use of it. Bitmessage's POW is not a way to reach consensus about a chain of events. POW as a means to limit email spam messages was already proposed with Hashcash in 1997. BM just added a P2P distributed message database to provide decentralization. The POW was no breakthrough from Bitcoin either: IMO Bitcoin's core concept (and the real genius) is the distributed agreement protocol, which is nowhere found in Bitmessage. That's what I meant with "POW as an agreement protocol", not just "POW", and why I think Bitmessage does not really benefit from Bitcoin's protocol.
