Greetings, Hive account@factionless, and I wish you a Warm Welcome to Steemit! :D

How warm? Well, I'm now one of your early followers, based simply on your fine comment here and on your intro post... :D

Indeed escrow is possible, and I have been told, and have seen hints that the mechanisms already exist within the Steemit blockchain.

While I'm not aware offhand of a "working tool" for escrow, one should be "doable" at least on the Steemit side of a transaction. When fiat is involved, the trouble always arises if there is a dispute of some sort, in which case some sort of arbitrator needs to be available to step in.

I suppose a mechanism could be created (may already exist?) on the fiat side as well, something involving debit cards? But in any case, a large part of my motivation here is to completely get away from the existing banking system.

Thanks so much for your comprehensive comments, and for reading and visiting my blog.

BTW, the thought of Hive account@creatr exchanging with Hive account@factionless right now is not entirely out of the question... Please see Bullet Points (4) and (8) above, and get back to me if you're interested. ;)
