Decentralised marketplace, maybe? Open-source, trustless. So people can't scam you. Not saying that blockchain is a good way to do this: For instance, privacy would be a major red-flag, as well as the question of who's going to do the mining. [edit] Just found this: https://openbazaar.org/ https://openbazaar.org/ Doesn't appear to use its own blockchain. Does use cryptocurrency though, for largely privacy and anti-censorship reasons. Uses multisig capabilities in Bitcoin to enable escrow/chargeback. As to why you wouldn't do the same thing for bananas: Weed is illegal, so any business selling weed is in danger of being shut down. Something decentralised is more immune to getting shutdown. Compare Napster (centralised) to BitTorrent (decentralised).
